Efficiency record for production LED
Nichia claims its 319A high-power LED is a record breaker by achieving a whopping 164 lm/W at 700 mA (5,000 K). And the 319A is a production device, Nichia say, i.e. not one shining brightly deep down in a liquid nitrogen vessel or in the minds of a few theorists at MIT. Mass production of this super LED is planned for late this month or early January 2017 so with a bit of luck you will be dazzled by your daughter’s new flashlight for Summer Camp.
