Lighting controls & dimming

Dim it your way

Good acoustic lighting has to fit the way a space is actually controlled, from a single switch in a café to a building-wide DALI system in an office. Most products in the Lumisono range are available with a choice of driver, so the same luminaire can work with the controls you already have, or with the system you’re planning.

Options vary by product and size. Each product page lists what is available, and we confirm the exact driver for every line of your schedule.

The options at a glance

Protocol	How it’s controlled	Wiring	Typical use
DALI / DALI-2	Digital, individually addressable	Mains + 2-core DALI bus	Offices, schools, healthcare, any building with a lighting control system or BMS
Casambi	Wireless (Bluetooth mesh), app, wall switches and sensors	Mains only	Refurbishments, restaurants and retail where new control cabling isn’t practical
Bluetooth app	Wireless, smartphone app	Mains only	Small spaces and single rooms
Push-dim / touch-dim	Retractive push switch: short press on/off, hold to dim	Mains + switched line	Meeting rooms, small offices, simple local control
Phase-cut (trailing edge)	Mains dimmer on the wall	Mains only	Hospitality and retrofit, using compatible trailing-edge dimmers
1–10 V	Analogue control signal	Mains + 2-core control	Existing analogue systems
On/off	Standard switch or contactor	Mains only	Where dimming isn’t needed

DALI and DALI-2

DALI (Digital Addressable Lighting Interface, IEC 62386) gives every luminaire its own address, so lights can be grouped, dimmed and scheduled individually, and report faults back to the system. DALI-2 is the current, certified version of the standard, with better interoperability between drivers, sensors and controllers from different manufacturers.

Choose DALI when the building has (or will have) a lighting control system, when you need scenes or daylight dimming, or when emergency and maintenance reporting matter.

Casambi and wireless control

Casambi creates a Bluetooth mesh between luminaires, so they can be controlled from an app, wireless wall switches or sensors without any control cabling. It’s ideal for refurbishments, listed buildings and hospitality spaces where lighting scenes change through the day and opening up ceilings isn’t an option.

Push-dim, phase-cut and 1–10 V

• Push-dim is the simplest dimmable option: a standard retractive switch controls on/off and dimming level, with no special controller.
• Phase-cut drivers work with mains wall dimmers. Use trailing-edge dimmers matched to the LED load; we’ll check compatibility for you.
• 1–10 V is an analogue control signal, useful when connecting to existing systems.

Tunable white

Selected products are available with tunable white, adjusting colour temperature from warm to cool (for example 2700 K to 5500 K). That’s useful in offices and schools for daylight-matched lighting, and in hospitality for warmer evening scenes.

Choosing the right option

• New office, school or healthcare building: DALI-2, usually with presence and daylight sensors.
• Restaurant, bar or retail refurbishment: Casambi, for scenes and app control with no new cabling.
• Single meeting room or small office: push-dim.
• Replacing lights on existing wall dimmers: phase-cut (trailing edge).
