1000 Lumen LED  E-mail

Combining 6 super bright LEDs into one chip, German company Osram Opto Semiconductors (maker of Sylvania lightbulbs in the U.S.) has made a major breakthrough in LED technology - more than 1,000 lumens from a single LED package. Created in conjunction with the NanoLux project and available this Summer, the Ostar Lighting LED uses sophisticated chip-packing technology and a special lens to create a white spotlight that's the equivalent of a 70W incandescent or 20W compact flourescent - enough to light a workspace comfortably at a distance of about six feet.

Light Emitting Diodes have been heralded as the "next big thing" in energy saving technology for years- they draw very little power, can last up to 1,000,000 hours (they average 50-100,000), are remarkably durable when compared to glass bulbs, and contain no mercury or lead. LEDs have become brighter and less expensive in recent years, resulting in little mini-flashlights and lawn ornaments. We promise better things from this remarkable technology soon.

LEDs have recently been used in commercial applications such as landscaping, grocery stores, stage lighting, and as we recently noted, in street lights. Until now there was nothing powerful and compact enough to be used as a direct replacement for an incandescent or compact flourescent lightbulb, and while this doesn't quite fulfill our dream of the "perfect light bulb", it gets us closer.

At 1,000ma the Ostar Lighting LED produces 1,100 lumens from 22 watts - at 50 lumens per watt, that's not quite as good as the 60 lm/W I get from the 13 watt CFLs on sale at Wal-Mart today, but still dramatically better than the 15 lm/W an incandescent might get. At lower current the LED's efficacy really "shines" - drawing 700ma it gets 65 lm/W and at 350ma it gets 75 lm/W. Pricing, unfortunately, is not mentioned.
