I had a ReefStar 150 W setup, and I didn't think the quality was very good. Maybe the higher wattage units are better, but the reflector in mine was ineffective, and the ballast died after a couple of years. I went to a Lumen Max 2 pendant and like it much better, although it's a bit of a DIY project to wire the ballast. I suppose some vendors might sell a pre-wired ballast.
