I recently read an article about the advances in LED lighting in the USA Today technology section. Despite the sometimes questionable slant of USA Today's hard news, their Tech section does a decent job. I have included a link to the article at the end of my post.
Apparently the technology has taken off in the past few years to the point where LEDs can recreate any color of light (including sunlight) by using a combination of red, green, and blue lighting (just light lighting a stage with halide lights and gels).
Just this week, researchers at the Lighting Research Center at Rensselaer Polytechnic Institute in Troy, N.Y., said they had boosted the light output per watt of a white LED to almost six times that of an incandescent light bulb, beating even a compact fluorescent bulb in efficiency.

The exciting prospect of LED lighting is that it is solid state, lasts virtually forever, and is entirely self contained. Add to that list of benefits that the fact that LED lights give off little heat and use a fraction of the energy required by flourescent, incandescent, or MH bulbs.
The article discussed the fact that there would be an astounding number of commercial uses for such lighting, and theorized that the commercial volume would quickly drive down the production price to the point where consumers could think about purchasing LED home lighting solutions.
My question is: Has anyone heard about an all LED aquarium light? Currently Aqualight has the Lunalight, so they are certainly experimenting with the technology. An LED aquarium light, if done properly, would alter the aquarium lighting landscape. LEDs are sealed in plastic so there would be no condensation concerns. If the light fell into the tank, your fish might not get electrocuted! These lights are totally shock proof. In the article they mentioned firing a shotgun at one and it still worked! No more worrys about rattling the light or bulbs while doing a replant or a water change. The reduction in electricty expenses does not need any explanation. Between lights, heating, and filtration we aquarists certainly use our fair share of killowatts.
Please let me know if anything is on the horizon. This prospect has me totally jazzed!
