Cree has introduced a second generation of its XP-G lighting LED, claiming up to 20% more lm/W and 2.5x lm/dollar compared with the original, writes Steve Bush.

Called XP-G2, the device has the same 3.45×3.45mm footprint as the XP-G and “is compatible optically with the original, providing drop-in-ready performance enhancements”, said the firm.

Characterised and binned at 85°C, efficacy is up to 151 lm/W (350mA, 85°C) or 165 lm/W (350mA 25°C) in 6,000K cool white.

In 3,000K warm white, up to 133 lm/W (350mA, 85°C) or 145 lm/W (25°C) is available.

Maximums are: 1.5A, 4.9W and 488 lm (4.7W, 85°C).

Typical forward drop is 2.8V (350mA) and viewing angle is 115°.

“Luminaire makers seeking Energy Star qualification will have access to specification and performance data, including LM-80 reports,” said Cree. “XP-G2 LEDs are a successor product to the original XP-G LED for LM-80 data, accelerating qualification of luminaries using 3,000 hours of LM-80 data, instead of the normal 6,000 hours. The XP-G2 LED is also UL-recognized and features a level 4 rating.”
