One system, mixed lighting technologies

Phase dimmers use phase-cut dimming to bring 230V loads into a DALI or hybrid system. We help select devices matched to your loads for reliable, integrated control.

Common Applications

  • Retrofit installations
  • Mixed-technology environments
  • Legacy load integration
  • Flexible control upgrades

Common questions

  • When do I need a phase dimmer rather than a DALI dimmer?

    Use a phase dimmer when you need to dim and integrate legacy 230V loads into a DALI or hybrid system; use a DALI dimmer for digital control of DALI loads within the system. The right choice depends on your load types and how you want to control them. Share your loads and we can help select the most suitable device.

  • Can phase dimmers bring old lighting into a modern system?

    Often, yes. Phase-cut dimming lets suitable 230V loads be controlled within a DALI or hybrid system, so legacy lighting can be integrated rather than left separate. Suitability depends on the load type. Share the loads involved and we can help identify compatible phase dimmers and confirm they suit the application.

  • How do I ensure a phase dimmer suits my load?

    Compatibility depends on the load type and whether it is suitable for phase-cut dimming, along with the control protocol. Matching the dimmer to the load is essential for stable performance. Share the load details and we can help select a compatible phase dimmer and validate the combination, reducing the risk of poor or unstable dimming.

Phase Dimmer Selection

The right phase dimmer, matched to the load, integrates legacy lighting into your control system and delivers stable, flexible dimming.

  • Load Matching

    Load-suitable dimming

    We help match phase dimmers to your 230V loads, so dimming is stable and suited to the load type.

  • Integration

    Legacy into DALI

    Guidance on bringing legacy loads into a DALI or hybrid system for coordinated, flexible control.

  • Compatibility

    Validated combinations

    Advice on matching the dimmer, load and control protocol, so dimming performs reliably.

  • Retrofit

Selecting phase dimmers

Phase dimmers use phase-cut dimming to control light output and can integrate legacy 230V loads into DALI and hybrid control systems. This supports flexible control across mixed and retrofit installations. The right device depends on the load type, its suitability for phase dimming, and the control protocol. Correct matching protects dimming stability and system reliability.

Integrating legacy loads into DALI?

Phase dimmer selection depends on the load type, its suitability for phase dimming, and the control protocol. Share your loads and control approach and we can help select a compatible device and validate the combination, subject to confirming load suitability.

Frequently asked questions

  • What information do you need to recommend a phase dimmer?

    The most useful details are the load type and whether it is suitable for phase-cut dimming, the load rating, and the control protocol or system you are integrating with. With this we can help select a compatible phase dimmer and validate the combination, flagging anything that needs checking. Sharing the load details helps ensure stable dimming.

  • Are all 230V loads suitable for phase dimming?

    Not all. Phase-cut dimming suits certain load types, and some loads are not designed to be phase-dimmed. Matching the dimmer to a suitable load is essential for stable performance. Share the loads and we can help confirm whether phase dimming is appropriate and recommend a compatible device, or suggest an alternative control approach.

  • Can I mix phase-dimmed and DALI lighting in one system?

    Yes. Phase dimmers let 230V loads be controlled within a DALI or hybrid system alongside DALI lighting, supporting mixed-technology control. We help select compatible devices so the system coordinates consistently. Sharing your loads and control objectives lets us recommend a suitable combination for reliable, flexible control.

  • Do you provide product data for phase dimmers?

    Yes. We can provide datasheets and technical documentation to support selection and compatibility. Tell us the loads and system and we can supply the relevant data or help identify a suitable phase dimmer, supporting stable dimming and reliable integration of legacy loads.

  • Can you supply phase dimmers alongside the rest of the system?

    Yes. We supply phase dimmers alongside DALI dimmers, relays, power supplies, interfaces and Tridonic components, so you can source a complete control system from one place. We help ensure the phase dimmer suits the loads and integrates with the system, supporting flexible, reliable control across the installation.
