I have one. It's pretty good light, but it gets pretty hot. I have a fan on the side of my wall that blows across the water and into the side of the light. Since it doesn't have any cooling, it probably cuts the T-5 lifespan nearly in half. I have also retro-fitted some moonlights onto the fixture, another thing it lacked.
Although I don't really have any complaints, if I were to do it again, I think I'd look for a fixture that has some fans built-in to keep things cool while the lights are on.
