Seoul Semiconductor's Z-Power P7 Series

SEOUL, Korea - Seoul Semiconductor (KOSDAQ: 046890), one of the world's leading LED manufacturers, today announced the development and commercial release of the ultra bright LED, Z-Power P7 Series. The Z-Power P7 Series, which the company started producing in volume quantities today, delivers the world's highest brightness of 900 lumens at 10-watt.


The 10W P7 single LED package produces luminous flux of 900 lumens -- much higher than the 60-watt general residential incandescent lamps, which only produce 660 lumens. The Z-Power P7 Series has an efficacy of 90 lumens per watt from a single package, which is eight times higher than incandescent lamps.

A compact fluorescent lamp consuming electricity of 15 watts and emitting light at 924 lumens shows an efficacy of 61 lumens per watt, while Seoul Semiconductor's Z-Power P7 Series' efficacy is nearly one-and-a-half times higher at 90 lumens per watt.

Seoul Semiconductor's Z-Power P7 Series can be applied in many fields such as general residential lighting, streetlights, a variety of task lights, high-end flashlights for military, police or rugged use, and landscape lighting requiring extremely bright light.

The Z-Power P7 Series overwhelms incandescent lamps in terms of energy efficiency, a significant development that signals LED's penetration into the general lighting market is just around the corner. Compared to general 60-watt incandescent lamps, which provide an efficacy of approximately 11 lumens per watt, Z-Power P7 Series emits light at 900 lumens and has efficacy of 90 lumens per watt. This breakthrough is happening at a time when rising oil prices and environmental concerns have fueled the interest for energy efficient systems all around the world.

In addition, the Z-Power P7 Series shows remarkable performance compared to compact fluorescent lamps, which are widely available at most retailers. In a comparison between Z-Power P7 and a compact fluorescent lamp consuming electricity of 15 watts and emitting light at 924 lumens, the compact fluorescent lamp shows an efficacy of 61 lumens per watt, while the Z-Power P7 Series' efficacy is nearly one-and-a-half times higher at 90 lumens per watt.

Another advantage is low light loss rate. General light sources, such as fluorescent lamps and incandescent lamps, emit in all directions and the light loss rate is high. This means that only 60% to 70% of light produced from general light sources is applied to illuminate an object. In contrast, Seoul Semiconductor's Z-Power P7 series is able to focus light in a specific direction based on the users' need. As a result, there is little loss of light generated from the source. Not only is efficacy of the Z-Power P7 Series nearly one-and-a-half times higher than general light bulbs, but when the light loss is considered, the actual luminous efficacy of the Z-Power P7 Series is nearly two-and-a-half times higher compared to a general light bulb of approximately the same luminous flux.

Seoul Semiconductor's Z-Power P7 Series can be applied in many fields such as general residential lighting, streetlights, a variety of task lights, high-end flashlights for military, police or rugged use, and landscape lighting requiring extremely bright light.

"Development of the 900 lumens, 90 lumens per watt P7 Series is a milestone achievement that reinforces Seoul Semiconductor's leadership position in the global LED industry," said Hyuk Won Kwon, a general director of Seoul Semiconductor's power LED business department. "We will develop new ultra high power products emitting over 1,000 lumens during the third quarter of this year to consolidate and continue advancing our technology."

Seoul Semiconductor won accolades from the LED industry when it announced the world's first 240 lumens single die Z-Power LED P4 Series in December 2006. Since then, the company has consecutively introduced many other innovative products to the market including the 420 lumens super bright single-package LED, the world's thinnest chip LED at 0.17mm, and Acriche featuring 80 lumens per watt which runs directly from AC outlets. These achievements have allowed Seoul Semiconductor to maintain its leadership position in the industry as one of the world's most competitive and innovative producers of leading edge LED technology.

Increasingly, governments around the world have proposed regulations to ban the use of inefficient incandescent lamps in an effort to conserve energy and substantially reduce CO2 emission that contributes to the greenhouse effect. Seoul Semiconductor is keeping pace with significant advancement in LED technology including the introduction of the P7 Series to offer consumers a viable alternative to incandescent lamps that is energy efficient and environmentally friendly.
