Comments: This 250w burns like a 15K. It definitely burns white as apposed to blue. Since buying this bulb a week ago, I purchased a Coral Color 20k which outs out a nice blue-ish hue.

Comments: I put this in the day it came in. So far a like the blue tint of this light. It came well packed, which is maybe something people forget about, but it's important when it comes to this kind of product. I can't really say much about how much my corals like it as of yet.
