LED Lamps to Replace Halogen and Wedge Bulbs

Sam Penny announced this week that four new, improved LED product are now available on the website: two to replace 12-volt halogen bulbs in “puck” fixtures and two to replace wedge-type bulbs in RV ceiling and sconce fixtures. The new halogen bulb replacements are the G4.RV2N-H and the G4.RV3N-Flex. The new wedge bulb replacements are the W9.RV2N-H and the W9.RV3N-H. Product details and digital pictures are available at the website link provided.
The original white LEDs used in 12-volt environments had a stark, blue hue. They were high-heat single-emitter chips and used a plastic cap to focus the light into a narrow beam – a feature great for flashlights but bad for general lighting. Neutek led the industry in adopting flat, wide-angle, natural hue warmer phosphers and always used multiple emitters in each LED element to obtain more light at lower temperatures. They also incorporated into every product several voltage and power control circuits needed to protect LEDs from the harsh electrical and thermal environment found in RVs and boats.

LED lamps need to comply with the WEEE Regulations

You may already be aware of the WEEE Regulations which require electrical and electronic equipment to be recycled when it reaches end-of-life.

LUXEON Rebel PC Light Output Improve

LUXEON Rebel PC Amber is establishing new performance benchmarks for its phosphor converted amber LED that are proving important not only for automotive and specialty markets but for the illumination market as well. Hot/Cold factor, which indicates how much light is delivered at operating conditions as opposed to test conditions, has increased 12% at 80C. Lumens and lumens per watt (efficacy) performance exceed that of all other amber power LEDs.
Amber LEDs have been essential for automotive and construction/manufacturing lighting applications for some time and in the lighting market, they have been implemented in entertainment solutions. Now, there is particular interest from the makers of retrofit bulbs designed to replace traditional incandescent lamps and replicate the color change from white to reddish-yellow as the light is dimmed.
Unlike conventional bulbs, white LEDs do not change color as they are dimmed so the "color" of the white light is always the same. Adding an amber LED to the system allows a retrofit bulb's light to change in a way that people already expect. However, amber LEDs typically have poor light output and color stability at the high temperatures found in retrofit bulbs. LUXEON Rebel PC Amber combines the same blue, thin film flip chip used in the company's white LUXEON LEDs. By adding proprietary Lumiramic phosphor technology, Philips Lumileds manufactures a highly stable, reliable amber LED that performs in high application temperatures, high humidity, and high drive currents, and still delivers the light output, efficacy, and quality of light required.
