Dialight Expands SAE/DOT Vehicle Lighting Portfolio with New 4”x6” LED Low Beam Headlamp

FARMINGDALE, N.J. - Dialight (LSE: DIA.L), an innovative global leader in LED lighting technology, today announced the addition of the new LED Low Beam 4”x6” Headlamp to its growing line of SAE/DOT approved LED lighting products for mass transit busses and commercial vehicles. Operating at less than 14 watts, the Dialight Low Beam Headlamp uses more than 70% less energy than conventional halogen headlamps and one-third the energy of the leading LED competitor in its class. This exceptional energy efficiency helps to reduce stress on the vehicles’ electrical system and potentially improve fuel economy.

Leveraging Dialight’s proprietary thermal design, the Dialight Low Beam Headlamp requires no cooling fans or other moving parts to manage heat, eliminating the failure points commonly found in other LED products. The combination of exceptional energy efficiency and innovative thermal management makes the long-life Dialight LED 4”x6” Low Beam the most reliable product of its kind for this application.

Where typical conventional headlamps require replacement about once every nine months, the Dialight unit offers a life expectancy of more than 10 full years, seven of those backed by Dialight’s full-replacement peace of mind warranty. This saves mass transit bus operators significant maintenance time and cost over the life of the product.

“This product is the latest edition in our family of highly efficient forward lighting that incorporates Dialight’s exclusive reflector-based optics design to enhance visibility in adverse weather conditions and reduce glare for oncoming traffic,” said Roy Burton, Dialight’s Group Chief Executive. “Based on the data we’ve seen, this new 4”x6” headlamp is far superior to anything else on the market with regard to energy efficiency and maintenance savings.”

Made in the USA at Dialight’s Roxboro, NC facility, the new 4”x6” headlamp meets the Buy America requirements and is SAE/DOT FMVSS108 compliant. Its rugged aluminum alloy die cast housing and hard-coated polycarbonate lens make the weather-proof unit impact resistant to hold up to the wear and tear of transit use. The plug-and-play unit is a perfect match in fit and function to existing incandescent headlamps and features universal 12V and 24V dual-voltage operation.

Dialight representatives will officially unveil the new product with a display unit at the 2011 Bus & Paratransit Conference, sponsored by the American Public Transportation Association, May 22-25 at the Marriott Memphis Downtown in Memphis, Tenn.
