They are 120W. 50/50 white and blue. The white and blue are on separate power cords so you can have only the blue on for actinic. They are quite bit cheaper than other comparable lights but they don't come with a dimmer. Personally I'm not worried about dimming them, and for the price, they're a great light!
Definitely worth looking into for anyone that wants high efficiency LED's and want to save money.
