dali.THE LIGHTING GUIDE
A brighter way to think about lighting

Good light is
always in control.

Meet DALI: the open digital language that helps lighting work smarter, feel better, and adapt to the spaces we use every day.

✳ DIGITAL BY DESIGN✳ INDIVIDUAL CONTROL✳ MADE FOR FLEXIBILITY✳ BETTER LIGHTING EXPERIENCES
01 / The protocol

Lighting that listens,
and responds.

DALI stands for Digital Addressable Lighting Interface. It is a standardized communication protocol that connects lighting equipment, giving each device a voice and making lighting easier to control as needs change.

◉
01 / 03

Addressable by nature

Control individual luminaires or arrange them into groups for a space that works the way you do.

↗
02 / 03

More than on and off

Adjust light levels, recall scenes and create the right atmosphere for different moments.

⌘
03 / 03

Built to evolve

Update groups and scenes through commissioning, without having to redesign the whole lighting installation.

02 / The bigger picture

One conversation.
Many possibilities.

A DALI system brings control devices and lighting equipment together over a shared two-wire bus. Commands go out, devices respond, and the whole space works as one.

Get to know the
building blocks.

From the devices behind the ceiling to the controls you touch, each part has a role to play in a thoughtfully designed lighting system.

▤
Control gear

LED drivers

Power the light source and translate DALI commands into dimming and other supported functions.

◫
The brain

Application controllers

Coordinate inputs, lighting behaviour, scenes and schedules according to the system design.

◉
The inputs

Sensors & switches

Provide input from people or the environment, such as occupancy or available daylight.

A thoughtful place to start

Better spaces begin
with better light.

Whether you're planning a new space or exploring smarter control, understanding the system is the first step.

04 / Good to know

A few bright answers.

What is the difference between DALI and DALI-2?

DALI-2 is the updated certification program based on the DALI standard. It includes requirements for control devices as well as control gear, with a focus on interoperability. Check the specific certification and supported features of each product.

Can DALI control lights individually?

Yes. Addressable control gear can be controlled individually, or assigned to groups and scenes during commissioning.

Is DALI only for large buildings?

No. DALI can be used in a range of spaces, from a single room to larger buildings. The appropriate system depends on the project and its control needs.

What should I look for when choosing equipment?

Check certification, compatibility, supported functions, power requirements and the needs of your project. A lighting controls professional can help with system design and commissioning.
