Product Features

The UL Listed Hi-lume A-Series Constant Voltage Driver is a high-performance LED driver that provides smooth, continuous 1% dimming for 12 V- and 24 V- constant voltage LED light bars or LED strip lights up to 40 watts. The UL listing ensures a safe and reliable installation because the driver is pre-packaged with its own specialized wiring and mounting enclosure.
