Bruce Pelton (center), vice president of Lumatech Corp. in Emeryville, Calif., recently presented Lab Director Charles Shank (left) with a royalty check for a lighting technology developed at Berkeley Lab and licensed to Lumatech. Inventor Michael Siminovitch (right) of the Lab's Lighting Research Group, developed the technology with Pelton.

Lumatech, one of the larger manufacturers of lighting retrofit products, makes a line of compact fluorescent lights used as replacements for incandescent down lights. Siminovitch and Pelton developed an efficient fixture geometry that includes novel optical and thermal management systems. The new technology, which was jointly patented by Lumatech and Berkeley Lab, is 15 to 20 percent more efficient than conventional technologies, and will advance the use of energy-wise, compact fluorescent lights.
