| Term | Meaning | Lighting use | Boundary |
|---|---|---|---|
| Phase-cut dimming | AC waveform dimming used with compatible loads and controls. | Common in retrofit dimming contexts. | Compatibility depends on the dimmer, driver and minimum load. |
| Trailing-edge dimming | A phase-cut method that turns off later in each AC cycle. | Often discussed for lower-load LED dimming. | Still requires a compatible driver and control pathway. |
| DALI | Digital Addressable Lighting Interface control. | Used for addressable lighting control and grouped scenes. | This row is a term definition, not commissioning guidance. |
| 0-10 V | Analogue control signal for compatible drivers. | Used in some commercial dimming systems. | Control wiring and isolation requirements are outside this table. |
| Constant-current driver | Driver that regulates LED current. | Common for LED modules where current control is specified. | Wrong driver type can damage equipment or create unsafe conditions. |
| Constant-voltage driver | Driver that supplies a set voltage to compatible LED loads. | Common for LED strip load estimates. | Sizing output is not wiring design or installation advice. |
