Additional Details

The XREWHT-L1-WG-R2 LED is typically packaged in a ceramic substrate with a silicone lens. It is designed to operate at a forward current ranging from a few milliamperes up to several hundred milliamperes, depending on the desired light output. The color temperature of the white light emitted by this LED is typically within the cool white range, providing a crisp and clear illumination. It is also compliant with RoHS standards, ensuring it is free from hazardous substances.

Proper thermal management is crucial for maintaining the performance and lifespan of this LED. Heat sinks or other cooling solutions are often used to dissipate heat generated during operation. The LED’s light output and color characteristics are specified at a junction temperature of 85°C. Its performance is also affected by the drive current, ambient temperature, and airflow. Detailed datasheets are available from Cree/Wolfspeed, providing comprehensive information on its electrical, optical, and thermal characteristics.
