    Very good - the phosphor is the main source of loss in LEDs.

    They are quite an unknown player in the LED market, Cree,general electric and phillips have spent billions investing in r&d developing their products.

    Having a new encapsulating material and proclaiming it "brighter" without any facts is quite a stretch considering cree this year are breaking the 160lumens/watt barrier.

    It would be better to show a prototype at least before making the claims but if it works out then it will be great.

    LED's are already way brighter than I remember in the 70's when I started with electronics. The colours were very dull back then.

    Ha! Just needs a funky 3D title in WordArt and it could be any school kid's science report. I particularly love the aliasing on the arrows. Nice.

    They still aren't efficient enough though.

    compared to what? They are massively more efficient than any competing lighting technology.

    Not always and it depends how define the efficiency. The chips themselves are efficient but when you start putting them in GU10 lamp form factor with nasty onboard circuitry then the efficient and lifetime drops massively.
