Philips Lumileds continues to advance its core LED technology and recent breakthroughs implemented in the latest LUXEON Rebel LEDs for illumination applications improve efficacy and light output performance at luminaire operating temperatures. Hot/Cold Factor compares the light output of the LED at 100°C Tj and at 25°C Tj—which is how LEDs are specified on a datasheet. LEDs in a luminaire are operated at very high junction temperatures, often between 80°C and 110°C.
