LR-100WHCF 12V

The LR-100WHCF series are high-efficiency 100W constant-voltage LED drivers with 5-in-1 dimming capability, designed for indoor and outdoor LED lighting applications. They support TRIAC, 0–10V, 1–10V, 10V PWM, and resistance dimming, delivering smooth, flicker-free dimming from 0–100% with ultra-low dimming depth. The drivers feature comprehensive protections, wide AC input range, IP67 housing, and long service life, making them suitable for professional and architectural lighting installations.

⚠️ It is recommended to keep ~20% margin to avoid running the power supply at 100% permanently (which wears it out prematurely).
