My Ray II and heater have arrived! I'm very pleased with the light so far. It's extremely lightweight and very elegantly designed. I must say, I could have built something that put out plenty more light, but it wouldn't look nearly as good. For what it is, and considering it's only 29w, the light output was surprisingly impressive.
Now just waiting on the eco-complete, which should be here tomorrow. Then I can finally get some water in here.
