Calling out to Weezard for LED advice
Cause I cooked them, too. Both of 'em. :sadcrying
They were working fine, although they wern't too close electrically.
Blue#1: 15.2V gave 1.5A, 14.7V gave 1.2A
Blue #2: 15.6v gave 1.5A, 15.1V gave 1.2A
I ran them singly, and together, and let 'em burn in for awhile. Here's where I must have made a mistake, but then I'm still not sure how these CC / CV supplies are "bending" the "law." It seemed like the pair should be able to handle 3A between them. 14.8V gave 2.2A when I dialed it in. I played around near those parametersfor awhile, disconnected them (spike there somehow?) and when I tried to reignite them, they too had one "corner" out.
So the blues are history, too. :i feel stupid:
Not really sure why I've had such a destructive night. I've still got 3 working reds, but now I don't want to hook them up as a group without some advice. Should 3 of them be able to take 3.6A at 10.8V, or will this PS somehow feed 3.6A to each of them?
DreadedHermie Reviewed by DreadedHermie on . Calling out to Weezard for LED advice My friend, I've read your stuff here and at Steve F.'s site. I want to build a dedicated flowering lamp using Ledengin 15 watters. (4 reds, 1 blue, and possibly 1 warm white; LM 317's so I can tweak the ratios.) Essentially, a copy of your 4+1 cake pan lamp but built on a 4 x 18" finned heatsink so I can see what's going on under it.) If I were to post my picks for power supply, resistor ratings / values, etc., would you critique and perhaps offer some guidance? I have already purchased Rating: 5Need advice wth plant problems?
