If i ever get some cash saved for it, had planned on adding like 6 kessil red boosters to my 3-400w hps flowering hoods. The kessils cover 2 foot diameter per light and my hoods are about 2 foot long, so i was thinking out hanging 2 kessils per hood, one at either end that wa it fully covers the area underneath my hood and the enhanced redspectrum would certainly be an added benefit.
I would only use them to supplement hid lighting atm, would not consider going full led only with no hid lighting.
My 0.02....
