LED Explosion Proof at 480 Volts Lighting fixtures are fixtures that are designed to operate on voltages that come from the panel at 480 volts. On the other hand, the voltage range that these lights' LED drivers function in is 277 to 480 volts. When the drivers are switched on, they immediately detect the incoming line voltage and adjust accordingly. The voltage does not have to be adjusted by the electrician.
Compared to an explosion-proof light working at 120 volts, an explosion-proof light operating at 480 volts would need a lot fewer amps per fixture. This implies that with 480 volts as opposed to 120 volts, the electrician might add more lights to each circuit. (four lights at 480 volts draw the same amount of amps as one light at 120 volts)
