Laser and Light Treatment of Acquired and Congenital Vascular Lesions

Laser and Light Treatment of Acquired and Congenital Vascular Lesions
IPL treatment of PWS
IPL devices are broadband filtered xenon flashlamps that work based on the principles of selective photothermolysis. The emission spectrum of 515–1200 nm is adjusted with the use of a series of cut-off filters, and the pulse duration ranges from approximately 0.5 to 100 msec, depending on the technology. The first commercial system, Photoderm VL (Lumenis, Yokneam, Israel) became available in 1994, and has been used to treat vascular anamolies. Another, IPL Technology (Danish Dermatologic Development [DDD] Hoersholm, Denmark) with a dual mode light filtering has also been used to treat PWS. Many other IPL system have recently been developed, and the appropriate parameters for congenital vascular lesions are being developed. The IPL has been used successfully to treat PWS (Fig. 39.7),78–80 but pulsed dye laser remains the treatment of choice.
IPL technology has also been used to treat pulsed dye laser-resistant PWS. In the study by Bjerring and associates seven of 15 patients achieved over 50% lesional lightening after four IPL treatments. Most of these patients had lesions involving the V2 dermatome (medial cheek and nose), which are relatively more difficult to lighten. Six of seven of these patients showed over 75% clearance of their PWS. A 550–950-nm filter was used with 8–30-msec pulse durations and fluences of 13–22 J/cm2 to achieve tissue purpura. The 530–750-nm filter can also be used with double 2.5-msec pulses, with a 10-msec delay and fluence of 8–10 J/cm2. Epidermal cooling was not required. Treatment resulted in immediate erythema and edema, and occasional crusting. Hypopigmentation was observed in three patients, hyperpigmentation in one patient, and epidermal atrophy in one patient.
The basics of body fat
Let’s start with the basics. Not all fat is created equal. We have two distinct types of fat in our bodies: subcutaneous fat (the kind that may roll over the waistband of your pants) and visceral fat (the stuff that lines your organs and is associated with diabetes and heart disease).
From here on out, when we refer to fat, we are talking about subcutaneous fat, as this is the type of fat that cryolipolysis targets. A recent study showed that the body’s ability to remove subcutaneous fat decreases with age, which means we are fighting an uphill battle with each birthday we celebrate.
From popsicles to freezing fat
Cryolipolysis machine — which literally translates into cold (cryo) fat (lipo) destruction (lysis) — was invented, in part, by observing what can happen when kids eat popsicles. No kidding here. The cofounders of this process were intrigued by something called “cold-induced fat necrosis” that was reported to occur after young children ate popsicles that were inadvertently left resting on the cheek for several minutes. Skin samples taken from pediatric patients like these showed inflammation in the fat, but normal overlying skin. Thus, it appeared that fat may be more sensitive to cold injury that other tissue types.
HOW DOES IT WORK?
Coolplas Fat Freeze Machine uses rounded paddles in one of four sizes to suction your skin and fat “like a vacuum,” says Roostaeian. While you sit in a reclined chair for up to two hours, cooling panels set to work crystallizing your fat cells. “It’s a mild discomfort that people seem to tolerate pretty well,” he says. “[You experience] suction and cooling sensations that eventually go numb.” In fact, the procedural setting is so relaxed that patients can bring laptops to do work, enjoy a movie, or simply nap while the machine goes to work.
WHO IS IT FOR?
Above all, emphasizes Roostaeian, CoolSculpting is “for someone who is looking for mild improvements,” explaining that it’s not designed for one-stop-shop major fat removal like liposuction. When clients come to Astarita for a consultation, she considers “their age, skin quality—will it rebound? Will it look good after volume is removed?—and how thick or pinchable their tissue is,” before approving them for treatment, because the suction panels can only treat the tissue it can access. “If someone has thick, firm tissue,” explains Astarita, “I won’t be able to give them a wow result.

WHAT ARE THE RESULTS?
“It often takes a few treatments to get to your optimum results,” says Roostaeian, who admits that a single treatment will yield very minimal change, sometimes imperceptible to clients. “One of the downsides of [CoolSculpting] is there’s a range for any one person. I’ve seen people look at before and after pictures and not be able to see the results.” All hope is not lost, however, because both experts agree that the more treatments you have, the more results you will see. What will happen eventually is an up to 25 percent fat reduction in a treatment area. “At best you get mild fat reduction—a slightly improved waistline, less bulging of any particular area that’s concerning. I would emphasize the word mild.”
WILL IT MAKE YOU LOSE WEIGHT?
“None of these devices shed pounds,” says Astarita, reminding potential patients that muscle weighs more than fat. When you’re shedding 25 percent of fat in a handful of tissue, it won’t add up to much on the scale, but, she counters, “When [you lose] what’s spilling over the top of your pants or your bra, it counts.” Her clients come to her in search of better proportions at their current weight, and may leave having dropped “one or two sizes in clothing.”

Although the mechanism of cryolipolysis is not completely understood, it is believed that vacuum suction with regulated cooling, impedes blood flow and induces crystallisation of the targeted adipose tissue with no permanent effect on the overlying dermis and epidermis. This cold induced ischaemia may promote cellular injury in adipose tissue via cellular oedema and mitochondrial free radical release. Another theory is that the initial insult of crystallisation and cold ischaemic injury is further perpetuated by ischaemia reperfusion injury, causing generation of reactive oxygen species, elevation of cytosolic calcium levels, and activation of apoptotic pathways.
Whichever the mechanism of injury, adipocytes undergo apoptosis, followed by a pronounced inflammatory response, resulting in their eventual removal from the treatment site within the following weeks. The inflammatory process sees an influx of inflammatory cells at 14 days post treatment, as adipocytes become surrounded by histiocytes, neutrophils, lymphocytes, and other mononuclear cells. At 14-30 days after treatment, macrophages and other phagocytes envelope and digest the lipid cells as part of the body’s natural response to injury. Initial concern was that cholesterol, triglycerides, low density lipoproteins (LDLs) and high density lipoproteins (HDLs), bilirubin and glucose levels were affected, however these have been shown to all stay within normal limits following the procedure.
Four weeks later, the inflammation lessens and the adipocyte volume decreases. Two to three months after treatment, the interlobular septa are distinctly thickened and the inflammatory process further subsides. Fat volume in the targeted area is apparently decreased and the septa account for the majority of the tissue volume.
Patients and treatment areas
Although all studies show reduction in every area examined, it is still unknown what areas are most responsive to cryolipolysis. Various factors may play a role in the degree of fat reduction observed after cryolipolysis. The vascularity, local cytoarchitecture, and metabolic activity of the specific fat depots in questions may play a role.
There is lack of substantial research to identify the ideal patient or even the ideal area to be treated. Given a modest (yet significant improvement of up to 25% reduction in subcutaneous fat), it is thought that the best candidates are those within their ideal weight range and those who engage in regular exercise, eat a healthy diet, have noticeable fat bulges on the trunk, are realistic in their expectations, and are willing to maintain the results of cryolipolysis with a healthy, active lifestyle.
New design Cryolipolysis is safe for all skin types, with no reported pigmentary changes, and is safe for repeated application. Ferraro et al. suggest that patients who require only small or moderate amounts of adipose tissue and cellulite removal would benefit most from cryolipolysis treatment. Contraindications include cold-induced conditions such as cryoglobunaemia, cold urticaria, and paroxysmal cold haemoglobinuria. Cryolipolysis should not be performed in treatment areas with severe varicose veins, dermatitis, or other cutaneous lesions.
HIFU Decide Guide: Which Device is for you?
High-Intensity Focused Ultrasound also known as HIFU machine is a non-surgical, non-invasive treatment procedure that tightens and lifts the skin using ultrasound energy. It is taken to be a safe and effective procedure for tightening the facial skin.
HIFU treatment procedure has loads of advantages over the traditional means of facial improvement: painless, zero incisions, scarring, and recovery time. In addition, it is far less expensive too.
Granted, HIFU is a popular means of looking better. Little wonder that there are tons of clinics and spas that offer services they claim can make you look better. However, that’s not enough reason for you to jump on the bandwagon of folks searching for ways to look better
Why Choosing The Right HIFU Device is Important?
Be sure to get a professional assessment before you start your HIFU treatment. This is because a professional and objective assessment from a specialist will help you discover the best form of treatment using the right multifunctional HIFU that is suitable for you.
Ultrasound technology is completely safe and has been used in medicine for decades. It works by contracting and shortening muscle fibers, thus causing the lifting and tightening effect that makes the skin look better.
Lifting, tightening, and fats melting are natural processes that result in a slimmer face, reduced jowl line & facial tightening. Confused about how to go about the HIFU facelift treatment in Singapore?
You will be able to decide on the best HIFU device to use when you finally decide to undertake the treatment. Let’s look at some of the most common HIFU devices in Singapore.
What is the working principle for HIFU vaginal machine?
The vaginal HIFU machine uses an noninvasive ultrasonic focusing technique to focus on the mucous membrane fibrous layer and muscle layer directly. Using ultrasonic waves as the energy source and taking advantage of its penetration and focus, the system will send out ultrasonic energy focusing in the the lamina and muscle fiber layer in a predetermined depth. A higher intensity of ultrasonic region, called focus region, is formed. In 0.1 second, the temperature of the region can reach to above 65 ℃ , so the collagen is reorganized and the normal tissue outside the focal region is undamaged. Therefore, the desired depth layer can obtain the ideal effect of collagen concentration, reorganization and regeneration. Ultimately, the mysterious effect of vagina tightening is achieved.

Every cartridge can reach 20000 lines lifetime. 

4D HIFU machine uses the power of High intensity focused ultrasound to safely lift and tighten skin. High intensity focused ultrasound is a form of energy that is significantly different than light such as IPL and Lasers or Electrical (Radio-Frequency) energy. HIFU, protects the skin surface, whilst precisely penetrating at deeper depths and higher temperatures than Radio Frequency for example, treating beyond the Dermis and Foundation layers, where structural weakening starts.
Tissue at the target point is heated to 65°C, Thermal Heat is created with the skin tissue creating both spaced ‘wounds’ and cellular friction – which in turn promotes healing, immediately contracts collagen and stimulates a rapid production. Over the next 90-180 days, the wound-healing response stimulates long-term tissue and leads to further lifting and tightening, with results that can last years.
4D HIFU also helps to improve the tone and all the features of your face such as your eyes, cheeks, mouth, chin and skin also making it a viable alternative to Botox, with the benefit of being able to maintain facial expression. Excellent for post surgical face lift to maintain the lift and treat blood stasis, scarring, and numbness. 
This mode could minimize treatment time achieves the great anti-aging result. It will be leading the new treading in the market, and help you to expand your business.

What is the LED Batten light?

LED batten lights have come along way in the last few years with the technology of LED, now batten lights have loads of different options as oppose to every batten being 2 x 36 fluorescent battens. LED battens now are much more streamlined with a slim and minimalist look but yet still put out the same brightness, this is great because 4 foot fluorescent battens are a real eye saw but now with LED battens they can manipulate the fittings to give a much cleaner and less commercial look. The best thing about battens is they are super practical with a real bright light and wide beam angles. When buying your LED upton batten lights there are a few considerations to make so in this blog I will run through what questions to ask before buying and our favourite best selling LED general batten lights.

IP Rating – The IP rated refers to the light being suitable for indoor or outdoor. If your application is outdoors then go with IP66, this is a high rating which will protect from water and dust. If you are buying for indoor you can still go with a IP66 as it will still protect from dust and physical impacts, otherwise an IP20 is fine as well with most batten still sealed. 
LED – There are still loads of fluorescent batten and tubes out there with people still replacing the tubes and ballasts, this is a bad idea as you can now buy for T8 LED direct replacement tubes. LED Battens use 70% less power and last 10 times longer than fluorescent tubes, LED tubes also now perform better in brightness and imitate a fluorescent tube without you knowing the difference. So always go with LED for all these reasons. LED tube lights are also much safer and better for the environment with fluorescent tubes containing mercury.
Integrated LED or LED Tubes – Most LED battens sold today are integrated which means once the light batten dies basically throw it out which isn’t ideal as you will need to replace and get an electrician to come back and replace, this can cost around $200 with the call out fee. When a manufacturer makes something integrated they can make it better with heat sinks and pushing up the performance as there is only so much technology you can fit into a tube. So if you are buying a LED integrated batten, only buy from quality brands, buying from LiteHome these brands means you are buying from a manufacturer with strict quality control. Avoid cheap brands as you will only get headaches and they maybe not even comply. When buying anything, I think practical and purchasing a batten with LED T8 tubes means you can always replace the tubes yourself so literally can’t go wrong, however with T8 battens, they look much more bulky and commercial, with LED integrated battens they much more slimline.
Colour Temperature – This is crucial to get right if you are installing LED battens in work environments such as garages, car parks, warehouses, workshops, kitchens etc, you should always look to use a temperature of a minimum 5000k as this colour spectrum reacts with the brain most in keeping alert and active. If your application needs to suit a heritage or traditional set up then you could look to use a 3000k or 4000k per perfuably and this will soften the light to create more ambience and warmth.

LED Linear light is a phrase we often hear in the realms of commercial interior design, but what exactly does it mean and how do we use it? This article aims to ‘de-mystify’ commercial LED Linear lighting and give you an insight into how and where to use it, to effortlessly turn cool offices into exceptional ones!

Firstly let’s talk about LEDs. An LED is short for ‘Light Emitting Diode’, which is a highly efficient long-lasting source of light that uses a semiconductor to convert electricity into light. When a suitable voltage is applied to the leads, electrons are able to recombine with ‘electron holes’ within the device, releasing energy in the form of photons (light). The colour of the LED trunk linear is determined by the energy band of the semiconductor.

De reden waarom de Led Linear Light niet oplicht

De reden waarom het led lineaire licht niet oplicht

Het led lineaire licht moet antistatisch zijn: omdat leds elektrostatisch gevoelige componenten zijn, als u geen antistatische maatregelen neemt bij het repareren van led lineaire lichten, zal de LED Linear Lamp worden doorgebrand, waardoor afval ontstaat. Men zou hier moeten opmerken dat de soldeerbout een antistatische soldeerbout moet gebruiken, en het onderhoudspersoneel moet ook antistatische maatregelen nemen (zoals het dragen van statische ringen en antistatische handschoenen, enz.)

Het aangepaste LEIDENE Lineaire Licht kan geen op hoge temperatuur ondersteunen: de twee belangrijke componenten van geleide lineaire lichten en FPC, geleide lineaire lichten zijn producten die geen op hoge temperatuur kunnen ondersteunen. Als FPC aan op hoge temperatuur verdergaat of zijn weerstaat temperatuur overschrijdt, zal het de dekkingsfilm van FPC veroorzaken te bellen, die direct zal veroorzaken de LEIDENE lineaire lamp om worden afgedankt. Tegelijkertijd is de LED Tri-Proof Lamp niet continu bestand tegen hoge temperaturen. Na een lange tijd bij hoge temperatuur, zal de LED chip doorbranden door de hoge temperatuur.

Daarom moet de soldeerbout die wordt gebruikt bij het repareren van de led-lichtstrip een temperatuurgeregelde soldeerbout zijn, en de temperatuur is beperkt tot een bereik, en het is verboden om naar believen te veranderen en in te stellen. Bovendien, zelfs zo, is het noodzakelijk om aandacht te besteden aan de soldeerbout niet te blijven op de pinnen van de LED Linear System lijn lamp voor meer dan 10 seconden tijdens het onderhoud. Als deze tijd wordt overschreden, kan de chip van de led-lijnlamp worden verbrand.

Als het led-lampje niet brandt, controleer dan of het circuit is aangesloten, of de verbinding slecht is en of de positieve en negatieve polen van de lichtbalk omgekeerd zijn aangesloten. De helderheid van de lichtbalk is duidelijk laag. Controleer of het nominale vermogen van de voeding lager is dan het vermogen van de lichtbalk, of dat de aansluitdraad te dun is, waardoor de aansluitdraad te veel stroom verbruikt. De voorkant van de lichtbalk is duidelijk helderder dan de achterkant. Controleer of de serielengte groter is dan de norm van de fabrikant.

Volgens de analyse van het materiaal van de printplaat, heeft de printplaat ook vele kwaliteitsniveaus. De meeste goedkope lijnlampen op de markt gebruiken het secundaire materiaal printplaat, die gemakkelijk delamineert na verhitting en de koperfolie is te dun. Gemakkelijk af te vallen, slechte hechting, koperfolie laag, en PCB laag zijn gemakkelijk te scheiden, niet om de stabiliteit van de schakeling te noemen, verwacht u dat de schakeling stabiel is, zelfs als de printplaat is als deze?

Met de voortdurende verbetering van de levensstandaard van de mensen, zijn LED-lampen overal te zien in het leven van mensen. Meer en meer klanten kiezen het voor verlichting, en het wordt begunstigd door iedereen voor zijn hoge helderheid, laag energieverbruik, en lange levensduur.

1. Wat moet ik doen als de LED High Bay Lamp-lamp niet brandt? De nieuw geïnstalleerde lamp moet worden gemeten met een elektrische pen om te zien of er spanning in het circuit zit. Als de lamp niet brandt, kan er een probleem zijn met de driver.

2.Wat moet ik doen als de helderheid van de LED-lamp afneemt? De lampkralen op elke string in de lamp zijn in serie geschakeld, en de strings zijn parallel geschakeld. Daarom zal, als er één lamp doorbrandt, de string met lampkralen niet oplichten. Als er niet veel lampkralen doorgebrand zijn, kunt u de twee soldeerpennen achter de doorgebrande lampkralen met een elektrische soldeerbout doorsolderen; als de lampkralen te veel doorbranden, moet u een nieuw lampkralenbord kopen.

3.Wat moet ik doen als het LED-lampje knippert? Controleer of de neutrale draad en de stroomdraad zijn omgewisseld. U moet controleren of de leiding bij de schakelaar rood is. Zo niet, overweeg dan dat de schakelaar mogelijk de neutrale lijn controleert. Vergeet niet deze op tijd te vervangen.

Veel huiseigenaren upgraden hun huizen van traditionele of klassieke stijlen naar ruimtes met een modern gevoel.

LED Tubular Light lineaire verlichting is een veelgebruikte verlichtingsarmatuur in de commerciële binnenhuisarchitectuur. Ze zijn echter niet exclusief voor deze sector. Met verschillende technologische ontwikkelingen is de esthetiek van lineaire verlichting geëvolueerd naar woonhuizen.

Maar voordat u de stap waagt, is het belangrijk om de verschillende soorten en toepassingen van lineaire verlichting te kennen. Lees verder om te ontdekken hoe u ze kunt gebruiken.

Wat is LED Panel Lamp lineaire verlichting?
Dit type plafondverlichting maakt gebruik van heel veel lichtgevende diodes (LED). Fabrikanten verpakken ze samen in een lange, smalle behuizing. Dit resulteert in een strook licht.

Het is een eenvoudig maar revolutionair concept voor de verlichting van woonruimtes. Voorheen bestond er wel LED lineaire verlichting, maar het verlichten van grote ruimtes was lastig. Je kon twee of meer fluorescentielampen gebruiken, maar het was moeilijk om een doorlopende lichtlijn te creëren.

Nu produceert LED Tube Light lineaire verlichting ononderbroken licht zonder zwarte of donkere vlekken achter te laten. Naarmate de technologie zich verder ontwikkelt, worden de esthetiek en de prestaties steeds beter.

Wat zijn de types van LED Wall Light lineaire verlichting?
Er zijn verschillende lineaire verlichtingsopties beschikbaar voor uw ruimte. Of het nu gaat om een kantoor of een grote woonruimte, het juiste type zal een tastbaar verschil maken. Bekijk deze twee soorten lineaire verlichting:

Hangende lineaire verlichting
Hangende lineaire verlichting is een van de populairste verlichtingstrends ter wereld. Creëer een onverwachte look door verschillende dramatische vormen en ophangniveaus te gebruiken.

Door de hoogte van de armaturen te verhogen of te verlagen, wordt de intensiteit van het licht aangepast. Dit kan een dramatisch verschil creëren voor de sfeer in een ruimte. U kunt kiezen tussen directe en indirecte opties om de nadruk te leggen op verschillende designelementen.

De eerste optie is ideaal voor sterke verlichting. Het verbetert de zichtbaarheid bij het uitvoeren van taken. De indirecte optie is uitstekend voor het creëren van de juiste sfeer of het uitbalanceren van harde elementen in een ruimte.

Ingebouwde lineaire verlichting
LED-inbouwstripverlichting neemt minder visuele ruimte in beslag. Het helpt om uw kamer groter te laten lijken omdat de verlichting terug in het oppervlak van het plafond is geplaatst.

Het doel van deze verlichting gaat verder dan het verschaffen van licht, het helpt de belangstelling voor de architectuur van de ruimte te bevorderen en creëert een eigentijdse sfeer. Google Promotional Products

Het is ook een geweldige optie om licht te werpen op specifieke objecten, zonder storende elementen toe te voegen aan het oppervlak van het plafond, zoals plafondlampen, tracklights of spots. Het resultaat is een strakke, eigentijdse en moderne look.

Godot Engine: Why is baking light making my scene darker?

Apparently I don’t understand real time lighting. I have an interior scene with some windows. The light is from an OmniLight near the ceiling, default environmental light from outside, and a desk lamp with emission. Without baking light, the scene looks like this:

enter image description here

Consistent with the documentation for emission, the desk lamp is not affecting the surrounding objects. I want to bake the light to see the lamp’s effect and to support low end hardware.

I followed the baked lightmaps tutorial and set the BakedLightmap’s extents to encompass the entire room. After baking, the scene looks like this:

enter image description here

I can see the lamp’s light, as expected, but now everything is too dark. It is unclear to me from Godot’s documentation if scenes include indirect light without baking. I have tried this with the OmniLight set to bake "all" and only indirect light.

What am I missing here?

Does the blindness inflicted by wall of light end when concentration on the spell does?

The wall of light spell states

When the wall appears, each creature in its area must make a Constitution saving throw. On a failed save, a creature takes 4d8 radiant damage, and it is blinded for 1 minute.

Xanathar’s Guide to Everything, page 170

The spell duration is "Concentration, up to 10 minutes," so the durations are already different. Would this imply that the blinded condition it affects would continue even if the spellcaster ended the spell or were knocked unconscious?

The brainchild of Yuta Hosokawa, READYMADE is a Japanese streetwear brand like no other. Their aesthetic is their own, and they flaunt their avant-garde sensibilities with heater collaborations. They were recently tapped by Nike and asked to inject the nieuwkomers with an experimental look. So, that’s exactly what they did, making their version of the Blazer into more of a piece of art than a sneaker.
</br></br>
We got our first whiff of the nike schoenen heren collaboration in October last year, and it’s fair to say that people were pretty divided. The basic construction of the Blazer has remained the same, the most major change is the large panels on either side and morphed Swoosh. Down below, there’s a bubbly midsole, while up top there is exposed foam to add to the deconstructed look. Two colourways have been created: a white with black accents and black with orange accents.
</br></br>
The relationship between nike schoenen dames and cult New York skate label Supreme is unparalleled. Ever since their first 2002 Dunk Low collaboration they’ve continually been spitting out heat, with each link-up garnering instant Grail status.
</br></br>
The dynamic duo are back in action this year on the nike outlet amsterdam, crafting four tasty combos with nods to their ’03 Dunk High colab. After constant leaks, rumours and teasers, a potential release date for the collection has finally surfaced.

Does the light from Branding Smite persist after the target dies? [duplicate]

The players were exploring Castle Ravenloft. A trap separated the human paladin from the rest of the party and placed him in a deep pit with no light source. In looking for a way out, he accidently released and then began to fight a wight. This was initially quite bad as he was attacking with disadvantage, while the wight (with darkvision) was attacking twice with advantage. The paladin remedied this by casting Branding Smite, hitting the wight, and making it glow.

Branding Smite, emphasis mine:

The next time you hit a creature with a weapon attack before this spell ends, the weapon gleams with astral radiance as you strike. The attack deals an extra 2d6 radiant damage to the target, which becomes visible if it is invisible, and the target sheds dim light in a 5-foot radius and can’t become invisible until the spell ends.

After two more hits and some Divine Smite, the wight was dead. The paladin wanted to hack off a piece of the glowing wight corpse and use it as a light source to help him climb out of the pit (spell duration is Concentration – 1 minute, the paladin needed three rounds to climb out of the pit). I hesitated, because when the wight ceased to be undead and became just dead, it was transformed from a creature into an object and was thus no longer a valid target of the spell.

Ultimately I ruled that one thing is a valid target for casting the spell itself, another is the persistent effects of the spell, and that the corpse would go on glowing for the duration. However, I would like to know RAW for this and whether all the effects of the spell would cease when the wight was killed.

Related: Is a target suppressed or removed when the target becomes invalid?. Superficially this might appear like a duplicate of my question. However, the question there is about the dominate person spell when the target is no longer a Humanoid because of polymorph. Obviously dominate person cannot continue to work if the target is no longer a Humanoid to dominate, but a dead wight could still continue to be a source of light. I feel like that question is a different situation than Branding Smite where the 2d6 radiant damage is the spell itself and the light produced is a persistent effect of the spell. Maybe the answer is not different, but I believe the question is different enough that it stands on its own.

Also, although not a reason to say that this is not a duplicate, I am unsatisfied with the accepted answer to that question being based on a Crawford tweet.

Does Deadly Agility work with light thrown weapons?

Does Deadly Agility work with light thrown weapons?

Deadly Agility (Combat)

Prerequisite(s): Weapon Finesse

Benefit(s): You may add your Dexterity modifier in place of your Strength modifier when wielding a light weapon or a weapon that gains the benefits of the Weapon Finesse feat (such as the rapier) when determining additional damage inflicted upon a successful attack.

When wielding a weapon in your off-hand, Deadly Agility will add the same fraction of Dexterity as you normally would for Strength.

I’m just asking as RAW "add your Dexterity modifier in place of your Strength modifier when wielding a light weapon or a weapon that gains the benefits of the Weapon Finesse feat" since there are weapon the are light that can be thrown (daggers, shuriken, darts, etc.).

If you succeed on the saving throw for the Sickening Radiance spell, do you still take the level of exhaustion and emit the light?

The Sickening Radiance spell says:

When a creature moves into the spell’s area for the first time on a turn or starts its turn there, that creature must succeed on a Constitution saving throw or take 4d10 radiant damage, and it suffers one level of exhaustion and emits a dim, greenish light in a 5-foot radius.

The grammar and punctuation here makes me wonder: do the level of exhaustion and greenish light happen regardless of the result of the saving throw, just like how some spells still deal half damage when you succeed on the save?

I suspect they do. Otherwise it should have been written "…must succeed on a Constitution saving throw or take 4d10 radiant damage, suffer one level of exhaustion, and emit a dim, greenish light…"

Should unarmed melee weapons like fists and claws have the *finesse* and *light* traits? [closed]

In DnD 5e you find under Melee Attacks:

Instead of using a weapon to make a melee weapon attack, you can use an unarmed strike: a punch, kick, head-butt, or similar forceful blow (none of which count as weapons). On a hit, an unarmed strike deals bludgeoning damage equal to 1 + your Strength modifier. You are proficient with your unarmed strikes.

Also Martial Arts for monks, and Claws for tabaxis and tortles deal with unarmed strikes.

All use Strength for the attack and damage roll, with the exception of the Martial Arts for monks, which accepts Dexterity too.

Should "unarmed strikes with these natural weapons" have the finesse and light traits, because wrestling and boxing are not only based on strength but also dexterity like wushu or bujutsu, and there is no reason to use two daggers but can’t do so with claws or fists, feets etc.? The monk still has more damage and would gain two-weapon fighting with its body. So it would not unbalance in game, but give the tabaxi and tortle non-throwable natural daggers.
