I was looking for some interesting lights for my soon to be indoor grow-op (no just annuals this spring) and I came across this light. It is a nice looking fixture with 4 HO T5's (54 watts each) in it ... $209.00. I have a single T5 and it is a nice light. If you can live with 6500K I expect this rocks...

The best thing is the replacement bulbs are $14.99, they are 95.29 lumens per watt...down side...They are in BC.
