Replacement guide
What is an LED?
An LED (light-emitting diode) is a solid-state light source. Commercial LED fixtures replace bulbs and ballasts with an integrated board: they run cooler and quieter, turn on instantly, last tens of thousands of hours, and typically cut lighting energy use substantially — up to 60% on lighting energy in the jobs we quote, with energy-only payback as fast as one year.
