Ok... I'm getting nowhere, here! I have searched everywhere I can think of for info reguarding the best Halide brand for my ballast(dual 175 watt Cool Touch). I bought it used so I don't know if it has the pulse upgrade. I am interested in Hamilton's or XM's, but they gotta be a true as possible 10k. Ushio's would be great, but I don't believe my ballast will fire em. I am currantly running 12k CoralVue's and think they're more like a 20k(too dim and blue for my liking). Davej seems very fond of his 10k Coralvue's and his corals look terrific!!! Argh ... any help would be appreciated.
