Occupancy sensors

Technology, mount, coverage, and the settings that make a sensor seem broken.

0–10V dimming interfaces

A separate low-voltage pair that dims a group of drivers together.

Relay panels

One cabinet that switches many lighting circuits. The relay rating matters more than the wattage.
