Choose centralized lighting accessories by matching the load and wiring: use three- or five-channel low-voltage modules for 12- or 24-volt constant-voltage LED tape, a 0-10V dimmer for compatible commercial-style fixtures, and an adaptive phase dimmer for phase-dimming loads such as LED, incandescent, halogen, or low-voltage lighting. Add terminal blocks to organize line, neutral, and load connections in a panelized installation, and select an accessory switch-dimmer when a compatible in-wall circuit needs additional points of control.

Plan for line, neutral, and load terminations at the centralized lighting panel, using the appropriate terminal blocks for dimmer, relay, 0–10V, or power-supply modules. Low-voltage LED accessories generally require a 12V or 24V DC constant-voltage power supply, while 0–10V and phase-dimming devices require their specified line-voltage wiring, and some in-wall controls require a neutral wire.

Centralized lighting accessories connect field wiring for line, neutral, and load to terminal blocks or centralized dimming modules housed in a lighting panel. The modules then switch or dim connected loads, while low-voltage LED control modules can communicate wirelessly with the control system and connect to LED tape through a constant-voltage power supply.

When selecting centralized lighting accessories, match the control type and channel count to the loads, such as line-voltage fixtures, 0-10V lighting, adaptive-phase loads, or low-voltage LED tape, and confirm the required power and wiring. For new construction, terminal blocks can support field-wire termination during rough-in and module installation during trim-out, while retrofit projects may benefit from accessory switch-dimmers that add control at existing wall locations.
