I am amazed how many people say they love their lights. I've been in the hobby 20 years and never loved my lights. Lots of it is a 'grass is greener' mentality-'if I had halides instead of t5s, I could keep Acropora easily', 'if I we LEDs instead of halides, we'd have less heat and use less electricity', 't5s are almost as efficient and have such a nice glow', 'look at that new LED technology, so much better'.
