LED Arrays

UL services cover light-emitting-diode (LED) arrays, modules, or other assemblies of LEDs, and circuitry for controlling the LEDs. The devices require connection to a source of power that, as a minimum, limits the voltage and current. This category also covers devices connected to isolated (non-utility connected) power sources, such as batteries, photovoltaic panels, fuel cells and the like.
