The XM-L2 fits in Cree’s track record of breaking barriers for High Power White LEDs. It typically takes 2-3 years for Cree to commercialize an R&D result into a high volume product. XM-L2 represents the commercialization of a 186 LPW product, when the 186 LPW barrier was achieved in the lab only 3 years ago. It is also important to note, Cree has a path to even higher levels of efficacy, from the announced R&D results up to 254 LPW. Many other LED manufacturers have begun to de-emphasize the benefits of higher levels of efficacy because they are not able to deliver higher efficacy products. As the designer will detail further in the training, new levels of efficacy means fewer LEDs, fewer optics and ultimately lower system cost. In addition higher efficacy LEDs means higher efficacy end solutions and ultimately newly enabled applications.
