That UFO design is being knocked off by different manufacturers all over China. Some work much better than others. Find a real person (not some undercover sales dick) who's had success with one (as in, successfully completed a grow) and get the same brand.

I would recommend 660nm reds over the more common 630nm (which is really a red-orange, IMO) if you have an option. 660's will give you buds as nice as HPS, if you know how to use them, and if you have enough of them.
