Makers of lighting controls fall into a few kinds. Some build one category: sensors, wall switches, relay panels, drivers, or timeclocks. Some sell a system, so the sensor, the switch, and the panel are meant to speak the same protocol. Some build the control into the fixture. Lines aimed at houses tend to sell switches, dimmers, and bulbs. Lines aimed at commercial buildings tend to sell sensors, panels, and schedules.
The useful comparison is the category and the interface. A sensor and a panel are not substitutes for each other. Two system lines work together only when the protocol matches: a 0–10V group, a digital addressable bus, a low-voltage switch circuit, or a building network such as BACnet. If the protocol differs, the parts will not run as one system.
Read voltage, load type, and the listing before you buy. A multi-voltage mark only covers the range printed next to it. A relay or a dimmer listed for incandescent loads is not automatically listed for LED drivers. Emergency gear has its own listing. It is not borrowed from the ordinary control catalog.
Start from the job. Pick the category, then the protocol you already have, then the voltage and the load. The buyer guides on this site walk through sensors, dimming, drivers, relay panels, timeclocks, and the lines on a spec sheet.
