Just fired up a new Hamilton 14k 250 watt SE bulb, what a nice color I am very happy. I had a 7-8 month old Radium 20k that I was happy with but wanted more growth from the corals. Anyone running them? What do you think?
Are any of you running double ended? From my experience their color seems to shift VERY fast (like 4 months) to the color of a 10k.
The 175 single end Hamilton 14k I run in the basement has held it's color for a year.
