I have one it has mostly white Leds with some blue the cheaper model has two switches the more expensive model only has one, it has a little bracket that fits nicely on the side of the tank. It is a basic light and cheap and works OK. It would be nicer if it had more blue leds.
i just ordered the ray2 daylight and the ray 2 actinic. ive been using the ray2 on my freshwater tanks and it is nice and very bright. both lights should come in this week. i could take a few pics and give a little input when they arrive. in total everything was under 200 for 2 30 inch lights.
