im coming out with different numbers on this.You have approx. 12 sq ft of canopy you're trying to flower, so I'd shoot for at least 320 watts of good diodes.
Drivers are usually sold as 240 watts, 320 watts, 480 watts, and 600 watts.
Plenty of different form factors to choose from so it depends on what you want to do.
I've used cobs, QB light engines, and strips on the fixtures I've built and they all work well.
regarding driving them hard, they are actually a little less efficient that way. lets use a 185 watt driver (200ish actual watts) to make thing simple.I want to push it real good! Haha . I like that idea of the two drivers . I'll be mounting them with the light for added heat in room because it gets cold sometimes ..anyways ...as I sit here and look at the space and the upcoming possibilities I have, I think I am going to make it a 2x2 for my mother's and clones and the other 2x5I want to just do SOG undermy own bare hand built light that's efficient! And not a waste of power. Do these strips like bridge lux have any red diodes or UVB ? Also I think I can get 24 1 gallon pots in the 2x5 area
So hlg 240 and I just ordered 20 of those ones from above from bridge lux ?regarding driving them hard, they are actually a little less efficient that way. lets use a 185 watt driver (200ish actual watts) to make thing simple.
those strips take a max of 1400ma so you could run 6 at full blast. if you instead run them at 1050ma x 8 strips you will get more light out of each watt to put it simple since the diodes are cooler. Ideally though, running them at only 700ma and using 12 strips makes them even more efficient. This would have the added benefit of more diodes spread over your canopy. Really comes down to how much you want to spend on strips and aluminum.
those ones that @TintEastwood linked you to I think have a tiny bit of red, but are 90cri. much better quality of light overall. they would be a great choice, i am thinking of grabbing some of those myself. just search the forum for eb gen3 and you will find a bunch of threads with people discussing them.
if you are only going to flower the 2x5 then i think the 2 185w drivers will be plenty. could probably do just fine with 2 150w.
240W is a little underpowered for a 2x5. You want 300W total to cover the extra foot.So hlg 240 and I just ordered 20 of those ones from above from bridge lux ?
