XLamp XR-E LEDs deliver unprecedented levels of white LED brightness and efficacy. In the cool white range (5000 K – 10,000 K) the XLamp XR-E offers standard order codes up to 122 lm minimum at 350 mA. XLamp XR-E LEDs in the warm and neutral range (2600 K – 5000 K) are binned according to proposed ANSI standards.

    LED's Advantages:

    • Efficiency: LEDs produce more light per watt than incandescent bulbs
    • Color: LEDs can emit light of an intended color without the use of color filters that traditional lighting methods require. This is more efficient and can lower initial costs
    • Size: LEDs can be very small and are easily populated onto printed circuit boards
    • On/Off Time: LEDs light up very quickly. A typical red indicator LED will achieve full brightness in microseconds. LEDs used in communications devices can have even faster response times
    • Cycling: LEDs are ideal for use in applications that are subject to frequent on-off cycling, unlike fluorescent lamps that burn out more quickly when cycled frequently, or HID lamps that require a long time before restarting
    • Dimming: LEDs can very easily be dimmed either by Pulse-width modulation or lowering the forward current
    • Cool Light: In contrast to most light sources, LEDs radiate very little heat in the form of IR that can cause damage to sensitive objects or fabrics. Wasted energy is dispersed as heat through the base of the LED
    • Slow Failure: LEDs mostly fail by dimming over time, rather than the abrupt burn-out of incandescent bulbs
    • Lifetime: LEDs can have a relatively long useful life. One report estimates 35,000 to 50,000 hours of useful life, though time to complete failure may be longer. Fluorescent tubes typically are rated at about 10,000 to 15,000 hours, depending partly on the conditions of use, and incandescent light bulbs at 1,000-2,000 hours
    • Shock Resistance: LEDs, being solid state components, are difficult to damage with external shock, unlike fluorescent and incandescent bulbs which are fragile
    • Focus: The solid package of the LED can be designed to focus its light. Incandescent and fluorescent sources often require an external reflector to collect light and direct it in a usable manner
    • Toxicity: LEDs do not contain mercury, unlike fluorescent lamps


    • Do not drive LED for more than 5 seconds without proper heat sink


    Package Included:

    • 1 x CREE XR-E R2 LED Emitter
