Cree's COB LEDs to operate beyond 60,000 hours at 105°C

February 28, 2017 // By Julien Happich
Cree has enhanced its industry-leading XLamp CXA2 family of chip-on-board (COB) LEDs, including new premium colour options, higher light output levels and the longest lifetimes published for this type of LED.

The premium colour quality options include high fidelity (98 CRI) and specialty colour points for the 9 to 19 mm LES sizes with up to 50 percent higher efficacy than LEDs of similar sizes and light quality. These enhancements to the CXA2 family LEDs give Cree’s customers the ability to upgrade the performance of existing designs and to sell their products into lighting applications where colour quality is important, such as museum, retail and medical lighting.

The CXA2 Standard Density LEDs now deliver up to 10 percent higher light output levels across all CRIs and light emitting surface (LES) sizes, providing the highest COB LED efficacy for all applications.  The CXA2 LEDs are claimed to be the only COB LEDs in the industry to have more than 11,000 hours of LM-80 data available. Based on this data, the CXA2 LEDs provide L90 lifetimes well beyond 60,000 hours, even at extreme 105°C test conditions. Product samples are available now and production quantities are available with standard lead times.
