I'm adding a bit of LED to a 1,8m² 2x 315w CMH flower area.
Been trying to figure out LED drivers for a day now, is suprisingly hard.
Okay, let's do a 320W white channel:
12x 4000k LM301B Strips, approx. 20V each.
A whopping 240V, if I do the strips all in series. It's the volts that tickle us, but the amperes that kill, right ...?
HLG-320H-C1050 should be the driver to do it? has a constant voltage region of 152 ~ 305V, my 240 is right in the middle.
At full power each of my 12 strips shoud get 320/12=26W, or 1,3 amps at 20V.
The driver is rated at 1050ma. At 240V, that's 252W.
If i go to 100% power on the driver, will it go past it's rated 1.05 amps, or is the voltage gonna go up? hmm, ¯\_(ツ)_/¯
and a 60W 660nm Red channel:
4x 50cm 10 pcs Osram Square Hyper Red, approx. 20V (I guess. min. is 16 and max. is 20V)
That makes 80V, 0,75A max.
I might wanna add the same amount red LEDs in parallel circuit for adjacent area, so I'll need ~120w.
HVGC-100-700 fits the bill, albeit not as nice as HLG series. HLG-120H-C1400 is a more efficient PSU but is awkwardly 150w and might get a bit bored.
Maybe I should put 2 and 2 strips in series for 40V and get a HLG-120H-42?
It's really 120w, looks neat and is 93% efficient. But a bit more cabling. Hmm, is this a coin-toss moment?
Soooo, any grave technical errors, better Ideas on drivers? I'm all ears.
I thought I'd go with 4000K LM301, because it's a more balanced spectrum than 3 or 3,5k. more healthy greens
60W of red is probably a bit much, I'd run at 10, 20W before trying anything crazy. Is 50W max, me thinks.
The item listed for the red strips says Oslon SSL hyper red, but I talked to the shop, they say they ship the newer Oslon Sqares.
