I never answered your question though, it’s 10 of the gen 2 strips and 9 of the gen 1. There’s a slight difference in forward voltage between the two.

as soon as the rain stops i’m going to do some measuring.
i can get 40 280mm strips and put them in a square configuration on each corner
possibly 5 one in the the middle.
thoughts?

I think so? Do your measuring and see what works, then maybe put your artistic skills to work and draw me a picture lol. That’s for something besides the 2x2 right? 130-150 Watts is probably more than you need for it.

yea,that is losing the blurple lights…lol i’ll move then to the other side of my room with hps light…
Gotcha. If there’s more room, it’s a little easier to get Watts with the bigger strips. In terms of the 2x2 the 560’s are difficult to get in there, from my own experience.

ok,i can do 280mm for my little box…
on the 1120 3000k gen 2 ,a hlg-80h-700a will drive how many strips?

Three of the gen 2 1120mm strips. Do you need me to check the gen 1 strips?
How many of 1120’s are you thinking? Voltage wise you can go up to the hlg-240 at 1050ma. I think the hlg-185 would be voltage limit at 700ma. And they have the 120 (150 watt max) in there too

idk, i have two 2by 4 pieces maybe10-14 strips?

What do you want to cover with them?

roughly 5by5’
Hmm… the hlg-185h-c700a has max 286 volts on the output. That’s 7 gen 2 1120mm for like 191 led watts, probably 200-210 wall watts.
5x5 is tough because you’re going to have to run them up a little for coverage, and it’s not the strips strength. If you want to try it on two fixtures, hlg-320h-c1050a will do 7 gen 2 strips at about 294 led watts and probably 310 wall watts. Two fixtures like that probably do pretty well.
If you decide to go that route, we’re talking just under 300 volts dc. So you’ll want to make sure your wiring is neat and tidy.

Two questions…
How important is having a dimmer on these lights?
And
Did you happen to see what the price difference was in the gen 2 560mm strips vs the 1120mm strips?
The lpc -150-1050 is like a $30 driver, but it doesn’t have any dimming. I think one of them will run 7 560mm strips, I eyeballed it quickly can run exact numbers later if need be. Anyway, if you ran 14 560mm strips and two drivers per fixture cost in that should be around $200 per fixture for leds and drivers for about 290ish led watts.

Not so much for you, although we don’t want that happening either!
Not sure if you got 300v wire, or 600. But the connectors are limited for 300v too. I always get a little sketched out dabbling in the neighborhood of component limitations is all.

You’re good without the dimming then?

No problem.
Here’s the kicker. The fv of 1120mm strips is around 40v. The fv of the 560mm strips is around 20v. So a driver that fits 3 1120’s but leaves some headroom could fit 7 560’s. Since the 560 is exactly half the 1120, 7 560’s is better than 3 1120’s.
Running at 700ma is going to take more strips to hit desired power level than 1050. But 700ma will be about 4-5% more efficient. 1050 is probably your best bet as far as cost goes, but I’ll help you figure it either way.
After that, we just have to consider voltage and current limitations of the different components.

1050 is ok with me @dbrn32
what kind of spacing would you recommend on the 560mm?
on a 2’by4’sheet how many strips would fit and still be, ‘‘safe but awesome’’…lol
i am considering since this is going to be an investment i just as well add potientiometer on it…
