Currently LED + T5 for me, but hopefully within a week or two it will be "LED, T5 and Halide" (which wasn't a listed option, I guess "other"?
). I'm going to shoehorn 2 Radiums back over my tank, because honestly after going away from Radiums, the tank was just never the same for me. So I'll keep the LEDs for the primary I think, T5's flanking for supplementation, and then the two Radiums will pile drive some additional intensity for mid-day. Will see how it goes, I have to modify my light rack to accomodate all the gear.
