Lumileds will be releasing a new white Luxeon (I assume it includes the I, III, V, K2, and rebel) with lumiramic technology which in short terms means an LED chip that is composed of a ceramic substrate, the thin film flip chip blue substrate layer and a Lumiramic phosphor top layer. Lumileds reports in the press release that the minimum lumens per watt of these LEDs will be 115lm/watt. These LEDs will be out on the market according to Lumileds in early 2008, but Lumileds will begin a sampling program in the fourth quarter of 2007 (mid september thru the end of December I assume). These new LEDs should be interesting to play with and are showing signs that lumileds is *Finally* catching up to Cree and SSC but is still lagging behind a bit. The only up side I really see to this is that it will make old Luxeon lights easily upgradeable (no messing with optics) to the new LED and the new LED die construction according to Lumileds should yield a better color temperature uniformity, therefore allowing Lumileds to get rid of at least 75% of the current cool white bins and making the binning structure much more stringent and color tint in white LEDs much more balanced. The press release is available here .
