Advantages
High brightness from a compact package
Excellent thermal performance when paired with a suitable heatsink
Long operating life (typically over 50,000 hours)
Available in white, monochromatic, UV, and infrared versions
Compatible with constant-current LED drivers
Suitable for demanding indoor and outdoor applications
Thermal Considerations
A 5W LED converts part of its input power into heat, so effective thermal management is essential. For reliable operation:
Use an aluminum MCPCB or copper substrate.
Mount the LED to an appropriate heatsink.
Drive the LED with a regulated constant-current driver.
Keep the LED junction temperature below the manufacturer's specified maximum (typically under 120–150°C).
Proper cooling helps maintain brightness, color stability, and long service life.
