Boasting a strong heat dissipation capability and high luminous efficiency, this COB LED features certain waterproof protection and corrosion resistance for reliable operation. Suited for commercial trawler lights and multi-scenario high-power demands.
Utilizing advanced flip-chip bonding and high-quality aluminum substrates, the 47x200mm WELCOB HF47200 75V/400W board can be made to handle a maximum of 400W, with a light efficacy of 130-150lm/W, replacing SMD LEDs in fishing lights, advertising lights, high-mast area lights, and Plant growth lamps, among others.
Features
- Large size flip chip packaging, no gold wire, low internal resistance, high light efficiency.
- 2.0mm thick high-quality aluminum substrate with superior heat dissipation performance.
- Prevent dead light failure caused by gold wire collapse or false welding, and support continuous all day lighting.
- 500 large flip chips ensure high stability, and the LED lifespan can reach 50000 hours.
- Welding design, no risk of short circuit and explosion on terminal, more stable solder joints, preventing water leakage from causing short circuit problems.
- The COB process ensures the moisture resistance, waterproofing, and corrosion resistance of LEDs.
