radium is nice
not on an Ice cap ballasthands down, great
I have to agree with both points... In my experiences there's nothing better then a Radium 20k bulb but it would depend on the ballast your using it with.not on an Ice cap ballast
thats a plan. wtg randyBorrow another bulb you know lights correctly and screw it in. If it looks similarly bad it is the ballast. Alternatively, take the questionable bulb to someone with a 250w set up and screw it in. If it looks good , you know it is the ballast, if it still looks bad it is the bulb.
Keyword 400w. Reeflux 20k 250w sucks horribly...400w is a whole other beast all together...I like the growth from a reeflux 20k 400 watt.. I think it's had the best growth, and the color is overly blue...
ok, but with what type of ballast?If you want to step down to a lower K, the pheonix SE 14k has that blue 20k look, gives great color and growth.
