LEDs still are not much more energy efficient than T5 High Output fluorescent lights (unless the LEDs are run at very low power levels) and LEDs are a lot more expensive.
The latest Cree LEDs that I have seen produce 1000 lumens at 10 watts (100 lumens per watt) and cost in the range of $10-$20 per unit for just the bare LEDs. A two bulb, 4 ft T5HO fluorescent fixture will produce 10,000 lumens at about 93 lumens per watt and cost $100 or less.
I have one of these T5HO fixtures:
48" Wet Location Fixture - 54W T-5/2 - TekSupply
Hybrid Mode
