LED lighting has made massive leaps and bounds lately. One of my other obsessions is a large saltwater reef aquarium where I grow corals. Corals are HIGHLY photosynthetic and require massive amounts of light.
Until recently I had a few thousand watts of high output metal halide lighting over the tanks, sucking up a MASSIVE amount of electricity and generating a ton of heat. (We're talking several hundred dollars a month in electricity alone)
Year and a half ago I replaced 'em all with new high output LED's. The amount of light actually went UP (I've got a PAR meter to measure light output in the photosynthetically actively frequencies) but the power usage dropped to about 1/10th of what it used to be, not to mention the heat output dropped.
I haven't switched to LED's on my Valk yet, but I'm thinking very hard about it now.
Thanks for the info!
