I got my G2-160 today and I'm impressed and glad I went with the 160w over the 110w. The color isn't as bad as I thought it would be, it seems to be in the 12k range. I won't have it up and running for a month or so, I plan on getting an Elos Mini. I put it over one of my other tanks to see the color and I liked it, an nice crisp white, not yellow at all. With only the blues on it was INCREDIBLE!!! My corals were absolutely glowing, I have used VHO, PC, and T5 actinics throughout the years and they do not even compare to the colors my corals showed with the blue led's. No start up issues, no flickering, everything seems pretty good, but only time will tell, but for right now, I'm impressed.
