Tony I have tried many of them and it all depends on what size tank you will be lighting, and what actinics will be used. If this is on the 30gal cube with no supplement I would consider the Phoenix 14k, AB 20k, Hellios 20k. If you're very concerned with par the phoenix is your only option, although I'm sure these is some new brand that I don't know of yet. I was able to get good growth with all these bulbs so I opted for the AB 20k, IMO best color.

Sorry if this is a silly question, but what's the AB in AB 20K?

I'd throw the Ushio 14K DE and the new Iwasaki 14K into the mix too. I love the Ushio lamp, but it might not be as blue as you are looking for. The Iwasaki might just fit the bill though it is no where near as blue as a Phoenix or any 20K. Also remember the ballast and reflector combo is going to change the way all these lamps appear.
