I agree...I'd like to see it more widely used before trying it out, but if you look
Here, there's been a LOT of research done, and they've actually shown the LEDs to produce more PUV than metal halide, use half as much energy, and produce little to no heat at all. On top of that, the Luxeon LEDs they use have roughly a 50,000 hour life (abt 11 years), reducing to about 70% output at that point. Can you imagine not changing bulbs for 10+ years?
They've also got pics of a reef tank they've been using to test the LED system for the past 2 years. You can check it out
