I just wanted share something interesting in addition my last post in this section regarding the deep red/ photo red 660nm LED's.
CREE have just set a new industry bench mark for 660nm LED's which is absolutely massive news for LED grow light manufacturers and DIY enthusiasts. You can see the full specs here http://www.cree.com/~/media/Files/C...d-Modules/XLamp/Data-and-Binning/XLampXPE.pdf. In short there new HE (high efficiency) Photo red 660nm can operate at a wall plug efficiency of around 55% which is a huge jump in performance and even more efficient than most white LED's. I have asked them to share some information about how they have managed to develop this new material technology and if this will lead to higher current deep red emitters in the same way that the developments of the blue LED led to higher current white emitters. Developments like this could eventually lower material costs of a good quality LED light considerably whilst increasing the performance.
