Cree Releases Highest Efficacy Color LEDs & Ceramic LEDs

June 27th, 2013 by  

XPE2_Warm_medCree, a leader in LEDs, recently announced the commercial availability of XLamp® XP-E2 color LEDs. According to the company, XP-E2 color LEDs produce up to 88% higher maximum light output than competing high-power color LEDs.

From Cree: “Built on Cree’s revolutionary SC³ Technology™ next-generation LED platform, the new XP-E2 color LEDs deliver higher lumens-per-watt and lumens-per-dollar compared to the original XP-E color LEDs to lower system costs for existing XP-E color designs. The new XP-E2 color LEDs leverage the same XP footprint (3.45mm x 3.45mm) and are optically compatible with the original XP-E LED – providing drop-in-ready performance enhancements to shorten design cycle and improve customer time to market…. XLamp XP-E2 color LEDs deliver up to 1409 mW for royal blue, 109 lumens for blue, 253 lumens for green, 203 lumens for amber, 193 lumens for red-orange and 155 lumens for red, all at maximum drive currents in the 3.45mm x 3.45mm footprint.”

ceramic LEDsEven more recently, Cree also announced that it is also now offering “the first family of mid-power ceramic LEDs that offer no-compromise performance and reliability,” the XLamp® XH Series LEDs.

“Unlike today’s common mid-power plastic packages, XLamp XH-G and XH-B LEDs enable lighting manufacturers to create a new generation of more energy-efficient, longer life LED lighting solutions without sacrificing cost or performance. XH LEDs are optimized for fluorescent replacement lighting applications such as troffers and panel lights, where high efficacy, lifetime and smooth appearance are critical.” Specs and key features include:

  • efficacy levels of up to 170 lumens-per-watt at 65 mA, 5000K, 80 CRI and 25°C.
  • designed to deliver the long L70 lifetimes at high temperature and high current operation.
  •  3.0mm x 3.0mm footprint package with a 13 percent wider beam angle than most plastic mid-power LEDs.
  • offered in 2700K to 7000K color temperatures with high CRI options available.

It’s great to see innovation and new consumer options expanding so fast in the LED arena. Do you have more cool LED news to share?

    I did the math on the little Xh-G led…
    For 26.8 lumens, the specs say about 2.9v at 65mA = .1885 watt.
    1 / .1885 = 5.305
    5.305 x 26.8 = 142 lumens per watt for the highest efficiency, 8300K led.
    And 124 lm/w for the 5000K neutral white

    Even though these “real numbers” suggest less efficiency (probably based on real world conditions, instead of “perfect” heat sinking and environmental conditions) these are still OVER TWICE as efficient than the Chinese leds!
