LEDs are unquestionably the future of aquaria lighting. The question is how long will it take for the volumes to ramp up so the prices can come down.
Right now, the manufacturers are feeding mightily at the 'early adopter' trough; prices are probably double what they could be.
As this effect wears off expect prices to get more competitive. With even a modest allowance for future bulb changes, purchasing an LED fixture will soon make a lot sense vs conventional lights.
I'll go out on a limb and predict that within 2 years, you'll be able to buy a quality 48" LED fixture that will replace a MH/T5 setup for $1000 or less.
I can hardly wait.
In fact, I may not. If I upgrade tanks, I'll consider making my own LED fixture.
