The latest XHP packaged LED from Cree can deliver up to 2654 lm to enable high-intensity spot and street lighting

The latest XHP cree LEDs are available in 6V and 12V nominal forward-voltage configurations and can be driven at a maximum of 3A and 1.5A, respectively. At maximum current lumen output is 2654. Cree said typical forward voltages are actually 11.2V and 5.6V and that leads to maximum efficacy of 165 lm/w whereas the first-generation products were in the 125–132-lm/w range.

As is typically the case with evolutionary LED lights announcements with newer products offering upgraded performance, SSL developers can easily update existing product designs passing on the performance improvement either in terms of maximum led lamp or luminaire output or in improved energy efficiency at the same output level of prior products. Or developers can shrink product form factor using fewer LEDs. And being that the second-generation packaged such LED bulb or led light products are based on the same basic technology platform as the first XHP50 products, Cree was able to quickly deliver the LM-80 data that is necessary for certifications such as Energy Star.

Already lighting manufacturers are making plans to use the new LEDs. "Our goals are to achieve the best cost-efficacy and versatility using the most efficient LEDs," said Lorenzo Trevisanello, R&D manager of Arianna. "Thanks to the XHP50.2 LED’s lumen density and proven reliability, even at high operating temperatures and drive currents, we are able to push the performance and size boundaries of our products even further. Arianna shares Cree’s vision that LEDs should not compromise quality or performance and should provide better lighting experiences in all aspects."

Cree now has XHP LEDs across three form factors. At the original launch, the company announced 7×7-mm XHP70 LEDs. And then in mid-2015, Cree announced the 3.45×3.45-mm XHP35 LEDs. Those LEDs are in the same footprint as other popular Cree high-power LEDs including the XP-G/G2, XP-L, and XP-E/E2.
