    An energy peak in the 490-nm cyan region enables BIOS’s SkyBlue technology to increase daytime alertness and now a new Lumileds LED delivers significant efficacy gain.

    Lumileds’ most recent executive changes include moving Matt Roney up to CEO, from his former position driving the automotive business for the LED manufacturer. (Photo credit: Image courtesy of Lumileds.)
