Dimmer

A dimmer controls lighting output only when it is compatible with the load and driver.

A dimmer is a lighting control device. Compatibility depends on the dimmer type, driver, load range, control method and installation context.

Technical meaning

  • A dimmer is a lighting control device that changes light output when the connected load and control method are compatible.
  • Dimming terms can describe phase-cut, 0-10 V, DALI or other control approaches, each with different compatibility requirements.

Calculation use

  • Dimmer notes help note whether a lighting estimate assumes fixed output or controlled output.
  • Driver and strip load calculations can include a dimming compatibility note without turning the calculation into wiring advice.

Not the same as

  • A dimmer is not universally compatible with every LED lamp, driver or load size.
  • A dimmer note is not an instruction to connect controls or alter wiring.

Australian context

  • Australian lighting notes should name the dimming method as a compatibility item and keep any electrical work outside the public calculation.

Examples

ExampleValuePlanning note
Phase-cutLeading or trailing edgeOften discussed in retrofit contexts, but compatibility depends on the load and driver.
0-10 VControl signalA separate control method that should be matched with compatible control gear.
DALIDigital controlA control ecosystem term, not a simple brightness or wattage value.
