I think a combination of lenses 90 and 60 degree would be good but I have no idea.
You're not telling us where you want that 1500 PPFD. How far away from the light do you want that sort of intensity? A good new 1,000w HPS will put that out about 2-3 feet away, which means 1-1.5 feet from the bulb you're hitting bleaching levels of photons.
khyberkitsune Reviewed by khyberkitsune on . LED grow lights... input please. Hello guys, I'm exchanging eMails with a representative from a LED company. I asked him if they could produce a custom light for growing, and here's what he told me: Our options are as follow: 940nm, 850nm, 660nm, 630nm, 610nm, 590nm 570nm, 530nm, 510nm, 470nm, 460nm, 400nm and a total of 64 LEDs in the bulb.
