Can somebody explain the 1000 times efficiency gain? I thought that LED is over 10% effective on power so I don't get this.

- birschtl 13y agoI guess one factor in this "1000 times more efficient" scam is the higher photon output per surface area. LEDs efficiency drop a lot when maximizing photon per surface area. Edge emitting blue lasers have a much better power conversion rate than LEDs when driven at higher input power. The much better photon/surface area plus higher input power create a much narrower and brighter beam. Therfore only ~10% loss opposed to ~30% with LEDs... http://m.phys.org/news/2013-11-laser-diodes.html http://m.phys.org/news/2013-11-laser-diodes.html http://www.winlab.rutgers.edu/~crose/capstone12/entries/SolidStateLightingwBlueLaserDiodes-Revised.pdf http://www.winlab.rutgers.edu/~crose/capstone12/entries/Soli...
