100 Watt COB LED

WELCOB HA5054-220-100W-CW COB LED is a driverless AC COB light source that operates normally with a direct AC 220V-240V input voltage, requiring no external LED driver. This LED module features multiple circuit protection functions, enabling stable operation even under significant voltage fluctuations. The substrate uses 2.0W/(m·K) high-quality aluminum, offering excellent thermal conductivity, and combined with flip-chip packaging technology, improves the LED's heat dissipation efficiency significantly.

This LED boasts high brightness and reliable, stable performance, making it suitable for various high-heat-density, compact LED lights, including LED floodlights, streetlights, landscape lights, LED grow lights, industrial and mining lights, and explosion-proof lights.
