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?
