Decide how you want to control the lights before ordering. Standard switching, dimming, app control and voice control are different requirements and must be checked for the exact product combination.
Switching, dimming and smart control
| Requirement | What it means | Confirm before buying |
|---|---|---|
| Switching | On or off | Compatibility with the chosen switching equipment |
| Dimming | Adjustable brightness | Lamp or light, driver where applicable, and dimmer as one supported combination |
| Smart operation | Control through a specified system | Supported platform, control function and everyday operation without the app |
Smart control can provide switching without dimming. Likewise, separately switched groups offer different lighting scenes without changing the brightness of each lamp.
Start with the scene you want
If you only need bright working light and softer evening light, separately switched groups may meet the brief without dimming every fitting. If smooth brightness adjustment is essential, select and confirm the complete compatible system before ordering. Smart switching and dimming are different functions.
Keep everyday operation simple
Discuss how the lights will work from the wall, how other household members will use them and what happens if the app or network is unavailable. Ask for compatibility confirmation for the exact variants. LUMI’s confirmed 12W and 16W downlights are non-dimmable; do not specify them for a dimming circuit.
Identify the complete chain
Record the fixture, lamp, driver or power supply, existing switch or dimmer, and any proposed controller. Ask the manufacturer or supplier to confirm the supported combination. A fixture name alone cannot establish control compatibility.
Make your requirements specific
- Simple on/off switching or adjustable brightness?
- Existing dimmer to retain or a new control system?
- App or voice control, and which platform?
- One room or several separately controlled zones?
Do not assume a product is dimmable because it uses LEDs. Similarly, adding a smart switch does not by itself confirm that every connected lamp or driver will operate correctly.
For an existing installation
Share photographs of accessible model labels and describe the current controls. If there is flickering or unexpected behaviour, arrange assessment rather than repeatedly swapping unverified components.
Before checkout
Ask LUMI to confirm any control feature not clearly stated on the product page. Keep the written confirmation with your order. Browse the lighting range and request installation support separately where required.
