Oh this is too easy.Honest question, what do you like about this MH over other options?
I'll try to keep this short. 6 months ago I set up a 60g cube. On my old tank I had 2 metal halides plus 2 gen4 XR15s, I added these for fun, before that I had an XHO Reefbrite but thought the ramping up/down would be nice. So the new cube I'm using one metal halide with one gen4 pro with it. Price wise, the Radion is more money and about a third of the wattage. Based on running it not full out usually around 60 or 70watts. Compared to 250watts from the metal halide. I know efficiency and all that comes into play but these are simple numbers. I have a 12"x12" reflector, and it throws the light around. I like daylight viewing, not windex viewing, so the 14k spectrum is perfect. Output, blending, spread, coverage, natural shimmer, the Radion doesn't compare. I'm going SPS dominant and if I were to go all Radion I would have 3 XR15s or 2 XR30s over my tank to match my single metal halide. Aesthetics wise, looks fine to me, either way something is going to be hanging over my tank lol.
Not a good pic but this shows the aesthetics. I've since lowered the setup down a couple inches to around 12" above the tank.
