Cree introduces mid-power LEDs

LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has introduced its new XLamp XH Series of mid-power, ceramic LEDs. XH LEDs are optimized for fluorescent-replacement-lighting applications, such as troffers and panel lights, where high efficacy, lifetime and smooth appearance are critical, says the firm.

The XH-G LED delivers efficacy levels of up to 170 lumens-per-watt at 65mA, 5000K, 80 CRI and 25°C. In addition, the ceramic-based XH LEDs are designed to deliver the long L70 lifetimes at high temperature and high current operation of Cree’s other high-power LEDs, such as XP and XT LEDs. In comparison, plastic LEDs are known for very short L70 lifetimes at high-temperature and high-current operation, says the firm.

“We're excited that Cree is offering high-quality, ceramic-based, mid-power LEDs designed for real-world lighting applications,” says Roger Suen, supply chain management director, Light Engine. “The XH LED family gives us confidence in providing products that deliver stable lumen maintenance and good color consistency that cannot be duplicated by plastic packages.”

Both XH-G and XH-B LEDs share a common 3.0mm x 3.0mm footprint package with a 13% wider beam angle than most plastic mid-power LEDs. Cree XLamp XH LEDs are offered in 2700K to 7000K color temperatures with high-CRI options available. Samples are available now and production quantities are available with standard lead times.
