Look into Cree COB lights, they're usually built with LED setups.
I ended up grabbing the 3000w version of this brand for my 4 site rdwc setup. Here's a link as requested.
Wondering if I'd have been better off grabbing 2 of the 2000w ones instead to hang them next to each other... would have given better coverage imo.
The light itself tho is worth it regardless of which you end up with and gives great coverage, don't let my last statement throw u off. I was just looking at the prices and the 2 2000w would run just about the same $$ and I'd have technically been getting another 1000w.
Good luck!
