Dimming

LED lighting is a very different technology than traditional lighting. Because the light emitting diodes (LEDs) themselves are components on a circuit board, the light fixture has become an electronic device. This means that varying the current with a standard dimmer doesn’t necessarily have the same effect on the brightness of the light.

The ability to dim an LED device depends on the individual product. If the manufacturer has built the proper circuitry into the device, it can be dimmed. Generally speaking, lights meant for outdoor use are unable to be dimmed, while most interior lighting has a dimming feature.

Some products with dimming can be installed into an existing circuit with a standard dial dimmer and respond just like a halogen lamp. Most of our direct replacement lamps and residential recessed can light modules will respond to rheostat dimmers with no trouble.

Some commercial products can be dimmed using a 0-10v dimming circuit. Our commercial recessed can lights have this feature, as well as our lay-in panel lights.

The data sheets for each product indicate the dimming features in the ‘Control’ column. The code is ‘S’ for static (not dimming) and ‘D’ for dimming. 0-10v requirements are noted as well.
