Philips Lumileds Lighting Company is based in San Jose, California. It was started in 1999 as a joint venture between Philips and Agilent (spun off of HP), but in 2005 Philips bought Agilent's share, so now it is part of Philips. They developed some of the first power LEDs to be used in flashlights, like the Luxeon I, III, and V, and continue to produce the Luxeon Rebel. Red and blue Rebel LEDs are used in the household lightbulb that won the L Prize for Philips in 2011.
Luxeon RebelMaglites flashlights. Also used in early versions of Fenix LxD/PxD series. Datasheet
Luxeon Rebel ES
Same size package as the regular Rebel but with a larger die under the dome, the Rebel ES is capable of output of 200 lumens at 700mA and 320 lumens at 1000mA. The brightness bins below are not directly comparable to the ones above since the ES series are rated at a higher current. Datasheet
Slightly larger than the Cree XP-G at 3.7 mm square, the Luxeon T is binned at 700mA and 85°C with a maximum current of 1000mA. The Luxeon T was introduced in December 2012. The LED is available in CRI values of 70, 80, and 90. Tints are based on ANSI White points (27 corresponds to 2700K, up to 57 for 5700K). To compare to other LEDs which often use 25°C as the temperature, the values below have been increased by 8% from the datasheet.
Luxeon I a 1-watt LED capable of producing 30-60 lumens at 350mA, this LED was used in the Fenix L1S
Luxeon III a 3-watt LED LED capable of producing 60-90 lumens at currents up to 1400mA. Used in the Fenix L1T
Luxeon V a 5-watt LED
Luxeon K2 smaller than the earlier Luxeons, but with greater output of up to 140 lumens at 1500mA.
