A touch, a shortcut, a different atmosphere.
BEFORE YOU CHOOSE
Choose the right dimmable lamp.
A qualified electrician must verify the lamp, driver, load and wiring before connection. A dimmable label alone does not establish leading-edge compatibility.
Dimmable LED
Total ≤150 W; driver must support TRIAC leading-edge dimming.
Incandescent / halogen
Compatible resistive lighting ≤200 W total.
Minimum & low brightness
Recommended lamp load ≥5 W. Stable low-end brightness depends on the lamp and driver; some LEDs may flicker or turn off below 10%.
One compatible circuit
Do not mix lamp types or brands. No smart bulbs, CFLs, non-dimmable lamps or non-lighting appliances.
Wall box
Depth >38 mm plus wiring space; EU fixing 60 mm / US 83 mm. Follow the selected drawing.
DIMMING ON THE DISPLAY
Fine adjustment. Familiar shortcuts.
Set brightness on the LCD panel, use your shortcuts and customise their names. The device also remembers the previous brightness setting after a power interruption.
Adjust brightness on the screen or use a saved shortcut.
Real device interface examples; select a tab to explore. Actual settings are changed on the device or app, not on this page.
PERSONALISE YOUR DISPLAY
Your screen, your routine.
Set names and themes, adjust display brightness in the device settings, and choose the orientation to match your installation.

L8 · EDGE LIGHTING
A softer glow. Even at rest.
Let the panel edge breathe and change colour while idle, or choose a colour of your own. The decorative edge light is separate from the controlled lights or appliance.
EXPLORE THE GLOW
Automatic breathing & colour changes
Let the edge light fade gently in and out as its colour changes. Automatic mode takes care of the colours for you.
Light when you want it.
Set the edge light and its time settings on the device. These controls preview the effect on this page; they do not configure a switch.
CHOOSE YOUR BRIGHTNESS
Change the light. Change the mood.
Explore four supplied room illustrations. The switch offers 1% setting steps across 1–100%; actual light output and stable minimum brightness depend on the connected lamp and driver.
SMART LIVING
Adjust the lights from your phone.
Use Smart Living for brightness control, schedules and energy information. Connected features require setup, 2.4 GHz Wi-Fi and available network services. Screenshot figures illustrate the interface.
WI-FI MESH
L8 series. Different controls, one Mesh.
Mix compatible L8 switches in one network: 7-in-1, 4-in-1, dimmer, fan and water heater controls. Switches connect through neighbouring nodes, so each switch does not need a direct Wi-Fi connection to the router.

Configure the first switch where the router signal is good. The system automatically sets this first configured switch as the master.
Add the other switches
Complete setup for the other compatible switches. Keep adjacent Mesh switch nodes no more than 8 metres apart.
Let switches form the network
The switches automatically form their Mesh network. Any compatible switch can serve as the master when configured first; a separate gateway or host is not required.
L8 switches form a network within the L8 series; it does not extend household Wi-Fi for phones or computers. Remote app and cloud features still require the router, internet access and available services.

Check the installation space.
EU: 86 × 86 mm square or ≥60 mm round box; 60 mm fixing centres.
Verify the actual terminals and current model-specific wiring instructions with a qualified electrician before connection.
LAMP COMPATIBILITY
Match the driver as well as the lamp.
Compatible lighting
Incandescent and mains-voltage halogen lamps within 200 W, or dimmable LEDs within 150 W with drivers explicitly supporting TRIAC leading-edge dimming. Check the actual lamp and driver combination.
Do not connect
Non-dimmable LEDs, CFLs, fluorescent lamps, smart bulbs, non-lighting appliances, trailing-edge-only drivers, or lamps needing 0–10V, DALI or PWM signal control. Do not mix lamp types or brands on one circuit.
Check the low end
A 1% setting does not guarantee 1% light output for every lamp. Some LEDs may flicker or turn off below 10%. Leading-edge dimming may also produce a slight hum in some lamps or the switch; verify suitability for the room.
INSTALLATION
Confirm the circuit before connecting.
- Have a qualified electrician isolate power and verify live and neutral wires.
- Confirm lamp and driver compatibility, total load and one consistent lamp type and brand on the circuit.
- Check the selected wall box and fixing points. Verify actual terminal markings against the current model-specific wiring instructions from support.
- Secure the unit and panel, inspect connections, then restore power and check stable operation across the required brightness range.
