It appears that future of illumination will be based on both LED and Laser technology but nobody seem interested in the possible positive outcomes of the second to ground astronomy.

Any opinion?

I just skimmed, as I'm already late for work, but it looks like they are trying to get more light out of smaller packages, which I don't thik is good.  The intensity of LEDs is already a bit painful to lok at.  Squeezing even more light into a small space could be harmful unless it can be spread evenly over a very wide diffuser.  I've seen some LED lights that have very effective even diffusers, but still the surface brightness is harsh.  What positive effects do you see on astronomy?

It's not clear to me what the applications might be for this technology..
