Lumileds Lighting announced the release of the Luxeon Portable PWT1, the market's smallest power LED designed for flashlights and other portable lighting applications.

Lumileds Lighting today announced the release of the Luxeon Portable PWT1, the market's smallest power LED designed for flashlights and other portable lighting applications.

The new emitter generates 26 lumens at 350mA from a package size of only 2.0 x 1.6 x 0.7mm, providing market-leading light output for its size along with a 2,000-hour life and uniform white light produced by Lumileds' patented conformal coating process.

The Luxeon Portable PWT1 is roughly 75% smaller than other LEDs with similar light output and delivers about 4.5 times the amount of light (lumens) per square millimeter.

This enables manufacturers to build flashlights and other portable lighting products with smaller optics, smaller form factors and less weight than ever before.

Luxeon Portable PWT1 offers the best moisture sensitivity rating - JEDEC level 1- allowing for unlimited factory floor life.

This eliminates the need for dry storage or baking of the package after exposure to air.

The surface-mount package simplifies manufacturing and the toughest electrostatic discharge (ESD) protection in the industry with an 8kV ESD protection chip.

Lumileds' exclusive die coating technology ensures uniform coloration in the beam pattern, eliminating commercially unacceptable colour irregularities that occur with white LEDs from other vendors because of a lack of uniformity in phosphor coverage of the die.

Lumileds utilizes special tools and procedures to distribute the phosphor at a regulated and consistent thickness over the entire Luxeon chip.

The new emitter, which is lead-free and RoHS compliant, expands Lumileds' family of portable LED lighting solutions, which also includes the larger Luxeon V Portable with a 500-hour life and a typical flux of 120 lumens at 700 mA.

Luxeon Portable PWT1 joins the Luxeon I, Luxeon III, Luxeon V and Luxeon K2 products as the most widely used high-power LEDs for portable lighting applications.

Luxeon LEDs are selected for their ruggedness, longevity, quality of white light and efficacy in portable applications.

The datasheet (DS51) and Portable Lighting Designer's Guide are available now along with pricing and availability from Lumileds Future Electronics at www.lumiledsfuture.com.
