400W lamp suggestions for Reefbrite Pendant and Ballast


New member
I currently have a 20k/20k twinarc reef brite lamp 400w in a reef brite housing with reefbrite ballast. I am finding the lamps a bit unreliable - latest has stopped working after just 5 months. Being based in the UK I would have to import the hamilton lamps but can get access to radium and BLV lamps. I also have as well as the two reefbrite pendants, 3 x radion G5 on AB+ over my 8ft tank. The LEDS provide the blue to make the corals pop so was thinking of switching to 10k lamps for coral growth. I would be interested in halide users in the US opinion on this idea and which brands of lamp you would recommend with my ballast and pendant? Thanks in advance.
