I noticeds that about week ago...
I think someone had some mess in the year we have or had accidentally starter a time machine or so.
The IRC's were here since 1970's, with their practical use peaking in the first decade after 2000 (and featuring the described performance), I really haven't fount anything else in that article...

And the "more efficient than LED's" was originally meant as "more efficient than the less efficient LED's", well that was the case with standard incandescent and LED's already in the 1990's...

I've also heard from this. I'm just somewhat skeptical if we ever gonna see any real product as there has been very little information about how ready this technique is for real life productiuon. Still, it's interesting to see how it will develope.

But I wonder what is supposed to be novel there?
The IR reflection lamps are on the mass market since 2000, produced by practically all major lamp makers (well, till some of them decided to even stop manufacturing some of those products). The first experiments were here in 70's (and even at MIT), yielding the first attempt to bring this concept to the market, although at that time not successful.
The concept does improve the efficacy by about 30..50% together with doubling the lamp life in real, mass produced lamps (so no just some scientific demonstrators). So for the same lamp life as standard halogens the potential is already double efficacy in real life and for a demonstrator even higher.

This article does describe just this performance, nothing better. The only difference is the use of flat assembly, but that is just one of the many ways to use that concept.
