Using the new XP-G3 Royal Blue LED and the recently introduced XP-E High Efficiency Photo Red LED, Cree has created a new horticulture reference design that achieves a Photosynthetic Photon Flux (PPF) efficiency of up to 3.2μmol/J at steady-state, which is over 50 percent more efficient than the traditional high pressure sodium solutions in use today.

The XP-G3 Royal Blue LED delivers up to 3402mW radiant flux, which corresponds to 13 μmol/s PPF, at its 2A maximum current and 85 C junction temperature. The XP-G3 Royal Blue LED is built on Cree’s ceramic high-power technology, which can deliver excellent lifetimes even at the extreme temperature of 105ºC.

Product samples of the new XP-G3 Royal Blue LEDs are available now and production quantities are available with standard lead times.
