“Nichia 219 white LED offers typical 140 lumen output at 1 W input power with 5,000 K color temperature. Using a uniformly phosphor coated chip, Nichia 219 has the industry leading source brightness and tightest optical footprint. The spatial color uniformity is also optimized with Nichia’s leading phosphor technology. At 350 mA drive current, the typical forward voltage is only 3.0 V. Additionally, this package is capable of drive currents up to 1.5 A.”
Shuji Nakamura’s invention of the first high brightness blue-light LED, which was based on gallium nitride lead to the LED Lighting Phenomena.
