Deven,
Did you want a retro fit kit or a fixture? How many bulbs? Need to know how wide your tank is. Reefgeek has a wide selection of both.
As for bulbs, always get more than you need to get the look you want,look at 2@ATI blue+, UVL Super Actinic, ATI ProColor, UVL AquaSun, GE 6500K and Geismann Aquablue +. With these bulbs and individual reflectors, you can keep any type of corals and clams you want. Do you want a bluer look, looking for mainly growth? Or a combo of the two.
My current light config is:
Front to Back
ATI Blue+
UVL Super Actinic (Dusk Dawn)
Aqua Blue+
ATI Blue + (Dusk Dawn)
Pro Color
ATI Blue + (Dusk Dawn)
Hope that helps.
