Dimmable LED switches regulate the electrical power or control signal sent to compatible dimmable LED bulbs and fixtures, allowing the light level to rise or fall from the wall control, a companion control, or a connected lighting system. Standard LED dimmers support compatible line-voltage LED loads, while 0-10V dimmers work with four-wire 0-10V or 1-10V fixtures, and low-voltage modules control 12- or 24-volt constant-voltage LED strips.

Many dimmable LED switches require a neutral wire, while some companion controls or low-voltage dimming modules use different wiring arrangements. Before installation, confirm the switch’s wiring requirements, LED load compatibility, voltage, and whether the application uses standard line-voltage control, 0-10V control, or a separate low-voltage power supply.

Line-voltage dimmable LED switches regulate power directly to compatible LED fixtures on a line-voltage circuit, such as a 120V installation. 0-10V dimmable LED switches send a separate low-voltage control signal to compatible fixtures, often with a built-in relay for on/off control, so they require fixtures and wiring designed for 0-10V or 1-10V dimming.

Yes, many dimmable LED switches support multi-location control through companion switches, wireless controls, or connected lighting systems. Options in this category can also integrate with smart lighting platforms, allowing users to adjust LED lighting locally or remotely, create scenes, and coordinate control across multiple locations.
