Light Controller That Works Like an MP3
What do MP3s and light bulbs have in common? Quite a lot, it turns out, when the light bulbs are attached to a LumiSmart Intelligent Lighting Controller. The shoebox-sized solid state controller, developed by Cavet Technologies, costs $2,000, takes 20 minutes to install (with help from an electrician), and cuts electricity consumption by 30% to 40%.
The controller works by cutting off power to light bulbs for nanoseconds at a time--faster than a light or ballast can figure out. It's similar to compression algorithms used in MP3s, where cutting out select bits to decrease file size still maintains the file as a whole.
Cavet's controller is easy to use, too. "You plug it in, turn the circuit breaker panel on, and the configure level of light savings. There are 7 programs on it, optimized for different types of lights," explains David Berg, EVP of engineering at Cavet. The box doesn't discriminate by geographical difference, either--it will work on everything from 100-volt light fixtures in Japan all the way up to the 347-volt systems found in Canada and the U.S.
