dear all,
one of my favorite LED to use in random projects are the generic 10w Chinese COB. they're under rs 50 a piece and very powerful for what they are.
what puzzles me is absence of any research regarding over /under driving them ?.I have found at length research about the subject on 5mm and 1w- 5w single emmiters. but nothing about COB (Chinese or otherwise ).
anyone has any lead on them?
the ones I use are rated 900ma at about 9-11v. they have 9 dies in a matrix and are easily available on eBay.
thanks.
