The tech looks pretty nice, the spectrum looks excellent (seems to lean toward the old HPS spectrum, but with more blue), and the warranty looks great (although the devil is in the details, obviously; it is a "limited" warranty). If the price isn't too high, I'd say they would be a good choice.
Note: Looked at the website and see they are a brand new, V. 1.0 product. That's usually a red flag for me as I like to buy from companies/products with some history of reliability....
