Mmmmmm... I think those actinic Watts are just as valuable as the 10K Watts. My understanding is that the actinics give you the blue wavelength of light that's normal at the depth the corals are underwater. Yes... it does add up to better coloration from our eye's standpoint, but it also serves as valuable and needed lighting for coral. Or maybe I'm just reading what you wrote wrong.
Regardless... I agree that you can go without for a bit. No LFS
around you have any replacement bulbs available?
