do not know if you lot have already seen this, but I thought it was interesting:

Solar Panels Inspire LED Breakthrough : Solar Power Engineering

Some excerpts:

Light bulbs that last 100 years and fill rooms with brilliant ambiance may become a reality sooner rather than later, thanks to a National Renewable Energy Laboratory discovery.NREL scientists found a way to generate a tricky combination of green and red that may just prove to be the biggest boost for illumination since Edisonâ€™s light bulb.

For a decade, LED researchers had tried and failed to make a reliable efficient green light by putting indium into gallium nitride.
He and his fellow solar-cell researchers had dealt with the same problem trying to build a solar cell with gallium indium phosphide. When the lattices created by molecular gases donâ€™t match up with the lattices of the layer below, it canâ€™t grow well and the efficiency is very, very poor.
NRELâ€™s solar cell experts found a way around that. They put in some extra layers that gradually bridge the gap between the mismatched lattices of the cell layers.

Actually, that's pretty damn cool!!!!
I would love to see nice high output white LED, that you can dim, and color temp will not change!!!

Nice find Tripp, Thanks!!
