Same thing. Just look up catalina lights and you'll find lots of opinions. I've tried them for a nano a few years back because they did cheap custom work. From my experiences, the enclosures are built solidly enough. The reflector though could use some improvements. The ballast was an Advance ballast, the same ones hellolights use for thier retrofits. So all in all, not bad. Cheaper if you were to get a retrofit from hellolights, but if you need an enclosure, then its not too bad. The only thing is you might as well throw away thier crappy bulbs. So if you find a good deal on MH unit, just remember that you need to add $60 for each MH bulb to the cost.
