    Default CREE is working on interesting things

    Take for example, this recent patent application for an LED with multiple internal layers, that emit R, G, B, and UV which can also be tuned to adjust the color over a variety of shades:

    That would make the Kroma obsolete, or at least it would make it smaller!

    It looks to me that they have just found the recipe for making true white light...

    Sounds promising for sure... True white, no more tint issues, and just dial up red when you need it... Awesome...

    Do they mean the user can actually change the color of the light or that the R/G/B/UV mix can be fine tuned at the factory for a specific (white) tint or color temperature?

    This is one of the things I asked for in the ultimate light. To be able to turn any color you want it too!

    It seems they mean the color can be fine tuned by ajusting the layers, it does not look like, based on the drawings that you could control current to each layer individually which, would be necessary to to control color "on the fly".
