i know a few aquarium keepers who are switching over to LEd. the cost is crazy initially, but in the same area, the right make of LED produce far brighter light with considerably less heat.

in terms of dollar efficiency it is probably more economical to use t5 or cf (today), but they are not "brighter" lights.
