The right driver keeps your lighting reliable and compatible

The driver controls power, dimming and output for each luminaire. We help match drivers to modules, controls and existing systems.

Common Applications

  • OEM luminaire manufacturing
  • Retrofit and driver replacement
  • DALI control system integration
  • Emergency lighting schemes

Common questions

  • How do I find a replacement for an obsolete LED driver?

    Start with the details of the existing driver and luminaire: output current or voltage, wattage, dimming protocol and physical format. With this information we can help identify a compatible modern or successor driver. Where an exact match no longer exists, we can suggest suitable alternatives and explain any differences in dimming, size or wiring that may affect installation. Confirming module data helps avoid unsuitable substitutions.

  • Which driver is compatible with my LED module?

    Driver and module compatibility depends on matching the module’s forward voltage and current to the driver’s output range, along with the correct dimming method and control protocol. Share the module specification or product code and we can help confirm a suitable driver. Getting this right protects light output, flicker performance and long-term reliability, and reduces the risk of failures or unpredictable dimming once installed.

  • What is the difference between constant-current and constant-voltage drivers?

    Constant-current drivers deliver a fixed current and suit most individual LED modules, while constant-voltage drivers supply a fixed voltage and suit strip or multi-module loads wired in parallel. Choosing the wrong type can damage components or cause poor performance. If you are unsure which your luminaire needs, share the module or fixture details and we can help you select the correct driver type.

Driver Selection

Choosing the correct driver protects light quality, dimming performance and the long-term reliability of the whole luminaire.

  • Load Matching

    Driver and module matching

    We help match driver output to module voltage and current, protecting performance and avoiding premature failure or flicker.

  • DALI Compatibility

    Reliable controls integration

    Guidance on DALI and DALI-2 driver features helps ensure dimming, addressing and commissioning work correctly with your control system.

  • Replacements

    Obsolete driver replacement

    We help identify compatible successor or alternative drivers when an original is discontinued, reducing downtime and avoiding full luminaire replacement.

  • Programming

    Programmable driver guidance

    Programmable drivers can be configured to set output and behaviour; we can advise on suitable options based on your requirements.

Selecting and integrating LED drivers

LED drivers regulate the power supplied to LED modules and determine how they dim and perform. The range spans constant-current, constant-voltage, fixed-output, dimmable, DALI and programmable drivers, supporting everything from single luminaires to connected, controllable lighting schemes across commercial buildings.

How we support driver selection

  • Driver and module compatibility checks
  • Replacement and successor-product identification
  • DALI and control-protocol guidance
  • Dimming and output advice
  • Emergency driver and gear selection
  • Technical support and product sourcing

Featured use case

Frequently asked questions

  • Can you supply drivers for older or discontinued luminaires?

    In many cases, yes. When an original driver is no longer available, we can help identify a compatible successor or alternative based on the output, dimming protocol and module details. Where a direct equivalent does not exist, we can explain suitable options and any differences that may affect fit or wiring. Sharing the existing driver code and luminaire information helps us confirm the most suitable route.

  • What information do you need to recommend a driver?

    The most useful details are the LED module’s forward voltage and current or wattage, the required dimming method and control protocol, the number of modules per driver, and any size or wiring constraints. For a replacement, the existing driver’s product code is valuable. With this information we can help match a suitable driver and flag anything that may need checking before installation.

  • Are your LED drivers suitable for DALI-2 systems?

    Many Tridonic drivers support DALI and DALI-2, but features vary between products. The correct choice depends on the functions your control system requires, such as addressing, dimming behaviour and feedback. Tell us about the control system and luminaires involved, and we can help identify drivers with the appropriate protocol support, subject to confirming the full system requirements.

  • Can a programmable driver be set to a specific output?

    Programmable drivers allow output and certain operating parameters to be configured, which can help standardise performance or match a particular luminaire design. The available settings depend on the specific driver. Share your target output and application, and we can advise on suitable programmable options and what configuration would involve, so you can plan the approach with confidence.

  • How do I avoid ordering the wrong driver?

    The most common issues come from mismatched output, the wrong dimming protocol or an incompatible physical format. Confirming the module data, control requirements and any replacement details before ordering removes most of this risk. We can review the information with you and help confirm a suitable driver, reducing the chance of returns, delays or unsuitable substitutions on site.
