Cree announces the latest XLamp XHP35 family of LEDs with 50% more light output than Cree’s previous highest-performing single-die LED, setting a new performance standard for the 3.5mm footprint. Built on Cree’s SC5 Technology platform, the XHP35 LED introduces Cree’s breakthrough high-voltage power die architecture, empowering manufacturers to unleash the full capacity of extreme high power LEDs using existing drivers. The XHP35 LED delivers up to 1,833lm without the optical inefficiencies of a multi-die LED to enable new designs with reduced size and lower system costs.

Unlike other existing high power LEDs, the XHP35 family uses a 12V monolithic power die to deliver extreme high power performance at drive currents at or less than 1A, making the use of high power LEDs more accessible for lighting designers. This breakthrough is uniquely enabled by Cree’s SC5 Technology Platform built on Cree’s industry-leading silicon carbide technology and features significant advancements in epitaxial structure, chip architecture and an advanced light conversion system optimised for best thermal and optical performance.

The XHP35 LEDs are available in high density and high intensity versions that are optimised to deliver the maximum performance for specific applications. The XHP35 High Density LED delivers new levels of light output in the compact XP footprint for high lumen applications, such as outdoor and high bay lighting. The XHP35 High Intensity LED is optimised to deliver maximum candela through secondary optics to boost performance and reduce size for applications requiring high light intensity, such as stadium, torch and track lighting.

“We’re excited that the XHP35 LED brings the performance of Cree’s Extreme High Power LEDs to the XP footprint,” said Jorge Fraile, CEO, Hispaled. “In addition to delivering an impressive amount of light, the XHP35 LED allows us to leverage existing drivers to achieve the full performance of Cree’s high power LEDs at lower drive currents.”

“Cree continues to redefine the performance of high power LEDs. The XHP35 LED represents a breakthrough that goes well beyond the incremental advances of other LED suppliers,” said Dave Emerson, Vice President and General Manager, Cree LEDs. “Now, more than ever, manufacturers will be able to tap the full power of extreme high power LEDs to forge lighting designs that were previously thought to be impossible.”

Samples of both XLamp XHP35 and XHP35 High Intensity LEDs are available now and production quantities are available with standard lead times. The XHP35 LEDs are available in 70, 80 and 90CRI and colour temperatures ranging from 2700 to 8300K with 2-step and 3-step EasyWhite options.
