SST-40-W Specialty White LEDs

The SST-40-W is a 15 W high brightness cool white LED intended for directional applications requiring a combination of high efficacy and high lumen output. It operates at up to 5A input current, delivering in excess of 1,650 lm under real-life “hot” operating conditions (85ºC junction temperature). Its monolithic chip design removes any far-field optical artifacts commonly observed on products made of chip arrays, simplifying optical design. With a typical efficacy of 170 lm/W at 700 mA, the SST-40-W is ideal for battery-powered applications as well as any application requiring a high performance, directional and cost-effective LED solution.
