Lighting fixture?

[HUNTER1]

This fixture comes with these bulbs:
1 10k 2 actinic and 1 purple
I thought it should be 2 10k and 2 actinic, what's up with the purple?
They just changed it to this bulbs configuration, why? thanks

I hear the purple will bring out the reds in corals. Sounds like a nice combo, actually - but you may want to change the actinics out for a bulb like an ATI blue + (sounds like actinics aren't that great...weird, I know, but they're not as penetrating).

Sounds good and that took care of the purple bulb question, thanks

you're welcome! I'm no expert though, but that's what I've heard :)
