LED chip, lamp and lighting maker Cree Inc of Durham, NC, USA claims to have set a new industry benchmark with its higher-performance XLamp XP-G2 LEDs, boosting brightness by 7% compared to the existing XP-G2 family.
XP-G2 LEDs are used in a wide variety of applications, including street and area lighting, PAR replacement lamps and high-performance flashlights. The new XP-G2 LEDs now deliver up to 142 lumens per watt at 350mA, 85°C, or 155 lumens per watt at 350mA, 25°C, in warm white (3000K). This enables lighting manufacturers to use fewer LEDs to achieve the same brightness at a lower system cost or to increase performance levels using the same LED count and power, says Cree.
“The higher-performance XP-G2 results in fewer required LEDs, which means fewer optics, a smaller printed circuit board and less handling, all of which translates to lower system cost,” says Paul Thieken, Cree’s director of marketing, LED Components.
Cree is also announcing the availability of 6000 hours of LM-80 long-term testing data for the XP-G2 LED. The LM-80 data provides TM-21-reported L85 lifetimes of more than 36,000 hours, translating to just 15% light loss after four years, even at the maximum current of 1500mA. In addition, the XP-G2’s predecessor, the XLamp XP-G LED, now has more than 12,000 hours of LM-80 data available. All XP-G data sets provide TM-21-reported L95 lifetimes of more than 70,000 hours (8 years), reflecting the long-term reliability of the XLamp XP package.
The higher-performance XLamp XP-G2 LED samples are available now. Production quantities are available with standard lead times.
