Manufacturer Claims Abound in the Development of LED Technology

Cree's green XLamp XR-E is said to be 70 percent brighter than the company's previous generation of green LEDs.

GO Lighting Technologies says its GO Flat LED Lighting reduces electrical consumption by 20 percent or more when compared with fluorescent lighting and is fully recyclable with no hazardous disposal requirements. Osram Opto Semiconductors recently introduced the Diamond Dragon (inset), which the company claims is “the brightest single-chip surface-mount LED” on the market and can achieve a brightness of up to 250 lumens.

Philips Lumileds recently introduced the Luxeon K2 LED (inset), which the company says is the first of a line of products that will lower light costs while delivering more light and a higher efficacy. PowerXED from Lexedis Lighting is said to have “excellent thermal management” in addition to a color rendering index of up to 90 in the warm white range.

Osram's organic light-emitting diode (OLED) prototype boasts a luminous efficiency of more than 20 lm/W at a brightness of 1,000 cd/m2, while Seoul Semiconductor claims its product Acriche (inset), a semiconductor light source for AC power outlets, achieves near-daylight quality with 42 lm/W.
