I have the 150W Hamilton Reefstar HQI for sale. It's been used for 1 week. I had it over a 15 gallon and had major heat issues, and instead of buying a chiller, I've decided to go w/ a 70W fixture. The bulb is brand new, never been fired b/c I switched out the stock bulb for a Phoenix bulb. Everything is in perfect condition. For now, So Cal p/u only. Asking $190 OBO.
