(PhysOrg.com) -- For the first time, researchers have demonstrated that an LED can emit more optical power than the electrical power it consumes. Although scientifically intriguing, the results won’t immediately result in ultra-efficient commercial LEDs since the demonstration works only for LEDs with very low input power that produce very small amounts of light.
I’ve got new blue LED bulbs that emit 133 lux while consuming 5 watts of electricity, which is 26.6 lumens/watt.
It is so bright that it blows the room out with blue color/light, so I completely believe this article.
