Intematix lighting-quality LEDs set new price-performance benchmark

Priced below 1-cent per warm white lumen, Intematix’ C1109D LED is opening the door to wider adoption of energy efficient LED lighting

Fremont, California – April 28, 2010 -- Intematix Corp., a leading innovator in phosphors, LED components and solid state lighting solutions, today announced the introduction of its C1109D that sets a new value benchmark for lighting-quality LEDs. Ranging from 450 lumens at 143 lumens per dollar in cool white, to 345 lumens at 110 lumens per dollar in high color quality warm white, the ceramic-packaged LED is nominally rated at just 4.7 watts. A typical incandescent bulb would require 25 to 30 watts for an equivalent light output. The C1109D is suited for a wide array of luminaires, especially those demanding maximum operational cost-efficiency, such as street and roadway lighting, garages, gas station canopy, warehouse, and recessed downlights in restaurant, hospitality and other high usage applications.

“Breaking through 1-cent per lumen for a high color quality, warm white LED is precisely what the LED lighting industry needs in order to encourage more rapid adoption of this energy saving technology,” commented Ilkan Cokgor, Director of Business Development, Lighting Products, for Intematix. “While the business case for LED lighting in many 24x7 applications can be fairly clear, luminaire manufacturers are still struggling to show a short enough payback for the more common 12x7 applications, as you find on our roadways, in our parking lots and outdoor service environments, and in many downlight applications. With the LED offerings that have been available up to now, in order to make the business-case work, luminaire manufacturers are often forced to consider potentially less capable LEDs that may not deliver a consistent and high quality color over the long term. A quality LED product, at a breakthrough price point, is the solution.”

As with other Intematix patented chip-array-on-ceramic LEDs, the C1109D leverages Intematix' widely recognized patent-backed phosphors, with special production techniques, to deliver impressive color quality and highly controlled bin selections. At 4.7 watts, C1109D series delivers 95 lumens per watt (lm/W) from the 5000K correlated color temperature (CCT) cool white version. The 3000K CCT warm white version is a high color rendering implementation (CRI >80) well suited to general purpose lighting. At 9mm x 11mm, the package is compact enough for use in integral replacement lamps, such as R or PAR type bulbs, as well as other types of downlights and recessed fixtures.  The C1109D has several advanced design wins in luminaires that have received Energy Star certification.
