Located in media Comparison of voltage to current and luminous flux to current between the new FOC chip structure and a conventional chip Located in media Epistar reaches warm-white light with efficacy of 170 lm/W and CRI of 88 applying several new technologies Located in media Epistar's record breaking 162 lm/W 5000K is achieved by 45mil blue HV-LED. Located in media Sandia researcher Jeff Tsao examines the set-up used to test diode lasers as an alternative to LED lighting. Skeptics felt laser light would be too harsh to be acceptable. Research by Tsao and colleagues suggests the skeptics were wrong.

In this photo, the bowl on one side was illuminated by a diode laser light and the other was lit by a standard incandescent bulb. The aesthetic quality of diode laser lighting (left bowl) compares favorably with standard incandescent lighting (right). (Photo by Randy Montoya) Located in media Four laser beams — yellow, blue, green and red — converge to produce a pleasantly warm white light. Results suggest that diode-based lighting could be an attractive alternative to increasingly popular LED lighting, themselves an alternative to compact-florescent lights and incandescent bulbs.
