Rated 5 out of 5 by jerry044 Hamilton 20K bulbs...
I have used these on my 120 mixed reef for many years and intend on doing so in the future. I like the way they bring out the colors on my sps and lps and the way my corals grow and multiply. I replace them every year.

Rated 5 out of 5 by Josh30 PERFECT 20K BULB
These Hamilton 20,000k are a perfect blend of blue with a hint of white giving off a deep water look definitely doesn't need supplementation actinics but they make it even better this bulb reminds me of a phoenix 14k bulb side by side its hard to tell apart I recommend this bulb for the 20k lovers or anyone looking for a "blue" look for their reef and I also get good growth with these better then other 20k bulbs which seem to slow growth overall I give it 5 stars!!!!!!!!!

Rated 5 out of 5 by DJ2005 Excellent Color
I use the Hamilton 250 Watt 14K and WOW - I LOVE the color from this bulb. I have used several different metal halide bulbs but I find this one to be the perfect balance of blue and white light. It draws out a lot of fluorescent color from my corals. My corals have opened up well and are growing more than before. My frogspawn looks great under this bulb. I recommend it.

Rated 4 out of 5 by TonyM1955 The product is excellent for those still using halide
a rather inexpensive solution to the reef tank lighing requirements.. Halide lights are getting more and more difficult to find and some brands have a yellowish almost "halogen" coloration. These Hamilton lights are bright and white with a tint of blue and seem to not give off as much heat as other halides.. If you have a large reef aquarium setup, and do not need to retrofit your lighting to halide, these are a great way to go.
