Armacost Lighting 120-Watt universal dimming LED lighting driver provides the utmost in performance, reliability, economy and versatility. It uses an integrated microprocessor to automatically sense and optimize LED dimming performance based on the load and type of dimmer being used. This electronic, solid-state power Supply is also compatible with the Armacost Low-Voltage 12-Volt to 24-Volt dc dimmers and RGB LED lighting controllers. The 120-Watt universal power Supply works equally well whether powering a single 20-Watt LED puck light or 120-Watt of tape lighting, or a combination of both. A small, 20-Watt minimum power load is required for effective, flicker-free dimming. Connect up to 100% of the rated 120-Watt maximum load.
