## Description

COB LED for compact fixtures, provides cool white light with good flux and high efficiency, at 36V power supply through constant current driver. The uniform emitting surface of approximately 6 mm ensures easy integration and optical control, and the wide angle of approximately 115 degrees makes it suitable for downlight, retrofit and commercial lighting. Recommended power 3-7W, nominal current 200mA, maximum 400mA.
Power SMD LED, CXA1304C, COB type from the Cree XLamp CXA1304 family, designed for compact luminaires that require good luminous flux and high efficiency in an easy-to-integrate format. It has a uniform emitting surface of approximately 6 mm, a wide illumination angle of approximately 115 degrees and is suitable for both directional and non-directional applications, from lamp retrofit to downlight and commercial lighting.
The diode also allows connection on the top side.

For more details, download the data sheet from the product page.
Use:
Mount the COB on an aluminum heatsink, with thermal paste or thermal pad, without air gaps between the surfaces.
Use a 36V compatible constant current driver, do not power directly from the fixed voltage source.
Choose the current so that the power remains between 3 and 7 W, the power is calculated as P = V x I.
At 36 V, the recommended currents are approximately 80 mA for 3 W and 200 mA for 7 W, fine-tuned depending on the driver and temperature.
After starting, check the radiator temperature, if it heats up quickly, increase the radiator or reduce the current.
If you use a reflector or lens, optically center it on the COB and fix it mechanically without pressing directly on the emitting surface.
