Sam Woodward, an expert in the lighting industry, explains the various methods that are available to control LED lighting. He explains the LED retrofit lamps can be dimmed using either a leading edge or trailing edge dimmer, and that an LED fixture can be dimmed using either mains dimming or a low voltage protocol. The option that is chosen for LED fixtures will impact the performance outcome of the LEDs, and will impact infrastructure planning and zoning, due to wiring.
