148-lm/W LED cuts cost, time-to-market

Using a technology platform introduced in January ( www2.electronicproducts.com/-article-hlrc02_feb2012-html.aspx), the XLamp XT-E white LED not only delivers twice the lumens-per-dollar of other LEDs, but also delivers the highest efficacy in the industry — up to 148 lm/W in cool white (6,000 K) at 85°C and an operating current of 350 mA — to reduce the number of LEDs needed to achieve a given brightness. The warm-white (3,000-K) version provides 114 lm/W at 85°C and 350 mA.

With its 3.45 x 3.45-mm XP footprint, the LED can be used for almost all lighting applications, replacing existing XP LEDs in lighting to shorten the fixture design cycle. Further reducing time-to-market, the LED is a successor to XP-E high-efficiency LED, and therefore application for Energy Star qualification with the new LED requires only 3,000 hr of LM-80 data, instead of the usual 6,000 hr. (Samples, free; commodity pricing competitive with existing LEDs — samples available now, production quantities with standard lead times.)
