Alrighty guys, I'm not the bandwagon type, but you twisted my arm far enough and the price point(low enough that I could cover it with the change I hide from the wife and kids) helped drive it home. Placed my order through Digi on Thursday, had my package Saturday morning. So points for shipping speed and the packaging was adequate as well. I got 8 * 3500k 280mm and 3 5000k 560mm. If you're wondering why the odd numbers and different sizes it's like this: I was laying in bed, beyond medicated, watching a movie and of course led's, drivers and combos are ruining my attention. Remembered seeing this thread, hit up Digi and these were what I found that wasn't backordered and could be functional for any stage of growth. I used 1"x .125" aluminum flat bar for the heatsinks/bars. Those are bolted to .75"x .06" aluminum angle framework. I used a Meanwell RSP-320-24 that I already had and just backed it off with the internal pot. @ 19v(which is actually what it puts out when turned all the way down) she's drawing 500ma at the wall. Im lucky to have extremely stable line voltage that never seems to dip below 120-121 so that gives me roughly 61w at it's lowest setting. At the highest she draws 2.4a resulting in roughly 290w. Running at full tilt, the strips get warm and I literally mean JUST warm to the touch. So far, I'm beyond satisfied given the price, ease of installation, how even the light is spread and damn near everything else you could mention. Anyway, that's enough of my rambling, bring on the pics. Don't be too harsh please, I know it doesn't look the greatest. Oh, and I'm in the process of nursing the ladies back to health. I had to go out of town and the designated gardener turned out to be the designated asshole.

Im new here but have several EB I bought awhile back. Ive been trying to figure out all the LED stuff...

I looked at your photo trying to figure out the wiring? and help you could give would be great.

thnx

Exactly as the user above me... I saw the 3ftx3ft build on LedGardener except they used a Meanwell hlg-320-20b... I have the Meanwell RSP-320-24..I saw the user above had turned his V+ down.. ledgardener used 15 2ft EB strips and got 294W__the user here got as much wattage with less strips unless the 1footers he bought adds more power?

I still dont completely understand the math side of LEDs

I have the same EB 2000lm Bridgelux bxeb-l08560z 19.5V leds... the Meanwell RSP-320-24 ....I have 12 of the EB 2ft. (8) in 3500k an (4) in 5000k... for 3'x3'...
I think I need to order a few more...I think the 1 footers he used added to his voltage...
MY MATH__ with 12 strips... 2 in series 6 pair = 240v I need 320? something like that?
thnx

With a CV driver like you have, you're not adding up voltage of the strips,(in most cases, until you start pairing) You have a voltage set, and you are dividing current output from the driver, by the number of individual strips.
That driver puts out 13.4a, at a constant voltage of around 24. That is adjustable on other MW drivers.(edit: evidently this one too)
If you wire your 12 EBs, in parallel individualy, each strip will get 1100(ish) ma.
(Dividing 13.4 by 12 strips in parallel)
I'm not completely familiar with the RSP series, but I imagine they operate the same way as what I'm used to.
