The XLap XP-G3 LEDs from Cree are the third generation of the XLamp XPG platform. The LEDs deliver 31 percent more lumens and 8 percent higher lumens-per-watt than the previous generation. Optimised for directional, high-lumen applications from indoor and outdoor to portable and lamp retrofits, the XP-G3 LEDs deliver the benefits of the Cree XP-G platform — a compact, 3.45 × 3.45mm package and established ecosystem — enabling designers to simplify the design process and shorten time to market.

The LEDS which are available from Mouser Electronics, deliver over 205 lumens-per-watt at 350mA and up to 863 lm at 2A. The high-density LEDs are available in 3- and 5-step ANSI white color temperatures from 3,000K to 6,000K, and offer standard Colour Rendering Index (CRI) of 70 or 80.

The LEDs offer a maximum driver current of 2,000mA with low thermal resistance of 3 degrees Celsius per Watt, and offer a wide viewing angle of 125 degrees.

The new RoHS- and REACH‑compliant XLamp XP-G3 LEDs are characterised and binned at 85 degrees Celsius and meet the higher efficacy and lumen maintenance requirements of DLC classification. Based on the LM-80 standard, XP-G3 LEDs provide beyond 50,000 hours of L90 light levels, even at an extreme 105 degrees Celsius, 1500mA test condition.
