Ok got it, yes be nice, pity I dont have one , if some does be very interestingI meant measuring in a integrating sphere.
oh i forgot i have a 185c-1400 CC that would work for the 135WSame here with the drivers. I do have some 700 mA drivers though if these are efficient enough to work with that
happy to flip you one gratis if your happy to do a review here and have enough gear to put it through its paces?, Dont care if its good or bad, prefer an honest unbiased view as I dont want to waste anyones time on a product that does not exceed expectations, especially mineoh i forgot i have a 185c-1400 CC that would work for the 135W
I'd offer to be a tester myself but I'm not as much of a COB guru as a lot of the guys here.happy to flip you one gratis if your happy to do a review here and have enough gear to put it through its paces?, Dont care if its good or bad, prefer an honest unbiased view as I dont want to waste anyones time on a product that does not exceed expectations, especially mine

sure i will try to do a ppfd/W curve over a current range side by side vs a 3590 or two. similar to supra's top bin graph which i found very informative. a holder for it would be cool (if they exist) so i dont have to solder to chip. if not no biggie. ill email you.happy to flip you one gratis if your happy to do a review here and have enough gear to put it through its paces?, Dont care if its good or bad, prefer an honest unbiased view as I dont want to waste anyones time on a product that does not exceed expectations, especially mine

4-50C is a BIG range. Can you narrow it down a little?Have you seen the update on citizen cobs ? Now version 5: http://ce.citizen.co.jp/productse/info.php?no=107
Not much of a revolution in terms of watt-to-luminosity, but nice decrease in thermal resistance. That's truely where citizen shines: they are easy to cool. My clu-046, now running for 5months straight is constantly 4-50°C cooler than my cxb3070, albight running at 4W more. If only the chips were easier to source....
mine are too4-50C is a BIG range. Can you narrow it down a little?
Believe me when I tell you that my CXB3590 chips are running cooler than yours.
