And bull, any led will dim just by using it, now if its abused it will crap out much quicker than one kept in absolute perfect conditions, but it will still dim
ok, so if i set a spare regulator to a a mid range level until it reads say 15ma, i'll leave it at 2.1v or 2.3v or whatever it is, i'll have an identical one to that i wont touch (only to power it up once to compare brightness), and i'll leave it on for a week and i'll take a before and after picture... don't expect me to do it right now, but I will tomorrow... and i'll see how much visible differences they are
A week? Try 3 months maybe more to get a real drop.
I wonder if leds kept colder than room temp, say in a walk-in freezer, would last appreciably longer, more than 10-12%?
Or what using a led as a light sensor does to its lifetime?
