Independent DALI network without programming
As the unit is a MCU (Master Control Unit), it can be used without the traditional DALI MASTER. The controller receives mains power and the two wires (DALI bus) are fed directly to the DT8 RGB DALI transformers and controllers. Nothing else!
The device thus acts as a DALI master for up to 50 devices. This makes it ideal for an office or home as a simple controller without DALI programming.

What is DALI?
DALI dimming is a lighting control system that uses a digital protocol to communicate between the lighting controller and the lights themselves. This allows precise control of the brightness and colour of individual lights or groups of lights, as well as the storage and recall of pre-programmed lighting conditions. DALI dimming systems usually consist of a DALI controller that sends commands and DALI-compatible luminaires that can receive and respond to these commands.
DALI works best when it is designed and built from the ground up. This is because it needs two control wires running between the devices.
![DALI-järjestelmä]({{media url="wysiwyg/DALI-system.png"}})
The main features of a DALI system are
- It is a free protocol! Anyone
- can use it.
- DALI2 certification requires devices made by different companies to work together. LedStore only uses certified products.
- DALI is fairly easy to implement. You can install the power and control wires side by side, because they don't need to be protected. So 5 wires run everywhere: L, N, ground and 2 control wires (5×1,5 MMJ). the
- wires can be installed in any way you want, as long as they are within 100 m of the DALI BUS controller. The distance can be even greater if repeaters are used. The
- maximum recommended length of the DALI network is 300 m .
- Since DALI uses digital signals for communication instead of analogue signals, the devices have the same dimming values. This makes control groups highly functional and accurate.
- The system addressing system (DALI address) ensures that each device or group can be controlled individually.
- Up to 64 DALI ECDs can be
- controlled by one DALI master.
- Up to 64 DALI ECGs can be controlled by one DALI master. Up
- to 16 groups can be
- controlled by one DALI master. Up

DALI terminals
DALI is challenging for a beginner to understand. What do all the terms mean? Here are the terms in brief
DALI-master
A DALI master is a control centre or heart, which usually also contains the power supply for the DALI bus. The DALI-master is the brain of the system, controlling all the devices. The master can be programmed and used in different ways depending on the master.
- A USB connection is made between the computer and the master and the DALI software is installed on the computer.
- IOT version where the master is controlled by a mobile phone/tablet wirelessly over the same Wlan network.
DALI bus
Where the DALI Master is the heart of the system, the DALI bus is the artery. It carries all commands digitally between all devices. The bus is a 2-pole cable that connects to EACH DALI device! The maximum length of the bus is usually 300 meters. The bus can be extended with repeaters/power supplies or by adding DALI masters.
DALI bus power supply
This is usually included in the DALI master. Its function is to maintain the bus voltage, the bus carries a 100-300mA 16V voltage which carries information.
ECG
ECG stands for Electronic Contor Gear, which is any device that supplies voltage to lights etc. This includes DALI transformers and DALI relays. One DALI master can control up to 64 (OUTPUT) ECG devices.
ECD
ECD stands for Electronic Control Device, a device that controls devices such as DALI buttons and DALI sensors. One DALI master can control up to 64 (INPUT) ECDs.
Group
In DALI, devices can be added to groups. One DALI master can have up to 16 groups. The purpose of a group is to reduce the number of DALI signals in the network and to facilitate operation. When a group receives a command, for example, to dim, all ECG devices in that group will dim. The devices in the group therefore behave identically. If you want the devices in the group to be at different levels, this is a scene.
Scene
In DALI, scenes can be programmed/stored on buttons. There can be up to 16 scenes in one DALI master. These have values between 0 and 15. The purpose of a scene is to create different lighting modes.
For example, 50% of the output of a spotlight in a living room and 80% of the output of an LED strip light with a single command. This makes everyday use easier.
Advantages of DALI dimming
Dimmable DALI is an efficient and flexible lighting control technology that offers many advantages over traditional analogue dimming systems. Its accuracy, energy efficiency, scalability and ability to integrate with other building automation systems make it well suited to a wide range of applications in commercial, industrial and residential buildings. These are the benefits of DALI dimming:
- Accuracy: DALI dimming allows precise control of the brightness and colour of individual lights or groups of lights, which can be particularly useful in commercial, industrial and residential buildings. This allows greater control and flexibility in lighting design.
- Energy efficiency.
- Scalability: DALI dimming systems can be easily extended to control a large number of lights, making them ideal for large commercial or industrial projects.
- Integration: DALI dimming systems can be easily integrated with other building automation systems, such as HVAC and security systems, allowing better control and automation of building lighting.
- From simple on/off switching to more advanced control options such as setting and resetting pre-programmed lighting conditions, DALI dimming allows a wide range of options for controlling lights.
- A common standard: it ensures that devices from different manufacturers always work in the same way when connected together. You can also replace existing parts with newer and better ones as they become available.
- Easy to install: thanks to DALI fibre optic technology, you don't need to split lights into zones or keep track of wiring. DALI systems have two connected wires. These wires control all the devices. Installers don't need to keep track of everything because they don't need to know how the lights will eventually be installed.
- Easy to change. After a while, you might want to change the lights and get something nicer. With centralized software, you can change lighting profiles easily.

WHAT IS CRI, THE COLOUR RENDERING INDEX
High quality LED lights also have a high colour rendering index, or CRI. A good colour rendering index (CRI) for home use is above 90, and nowadays many market lights are unfortunately closer to 80.
CRI tells you how well an LED light displays colours as they should be. For designers and architects, as well as interior designers, it should be one of the most important considerations. Make sure the lighting is perfect so that your artwork is what it is meant to be.
Colour rendering index
The colour rendering index is expressed as a number on a scale from zero to 100, where 0 = no colour rendering and 100 = full colour rendering. The colour rendering index of LED lights is also known as Ra, which is measured on a smaller scale than CRI. This Ra value does not include red tones or skin tones, for example, so it is a 'glossed' figure for the true quality of an LED light.
RA value
The Ra value measures the reproduction of colours using eight different reference colours. CRI takes into account the wider (15) wavelength range, including reds and other warm colours.
The Ra value is calculated by cutting the wavelength range, weighting the blue and violet tones, and calculating the weighted average of R numbers 1-8.
Excluded from the Ra value are, for example, the colour rendering of bright reds, yellows and greens, and shades close to skin tone. These are described by R-values between 9 and 15. The following is a picture of a measurement result that easily confuses the consumer.
This measurement is from a 9W CCT Led spot

CCT CONTROLLABLE PRODUCT has won gold and bronze medals in two international design competitions in 2023!
Janne Halttu has been developing his own product family since the beginning of the company. Throughout the product development process, his own experience in building houses and installing lighting has been at the top of the list of requirements. The requirement list for CCT spotlights with colour temperature control included the following features:
- High quality - All parts of the luminaire are finished down to the connectors.
- High light quality - The LED circuitry of the luminaires has a very high colour rendering, CRI98!
- Smart home capability - Connectable to smart lighting management systems such as Zigbee, DALI2 without the need for a dedicated base transformer
- Quick to install - The luminaire has a quick connector for a Basic transformer, a pre-terminated connecting cable or a harness
- Minimum 600 Lumens - The luminaire has a removable opal which has the function of reducing the glare of the luminaire. By removing the lens, the light output can be increased by 10-15%
- Up to 55 mm high luminaire - The luminaire must fit into a standard Finnish ceiling structure consisting of 49x49 mm batten + 13 mm plasterboard.
- Small size transformer - The standard transformer of the luminaire can fit through the mounting hole of the luminaire.
- TRIAC dimmable - The basic transformer of the luminaire is TRIAC dimmable.
- Chainable - The standard transformer of the luminaire is chainable
- Long life - The luminaire has a burn time of +50,000 hours and a 7 year warranty
- Modular body - The luminaire's heat sink is a standard size spiral LED module which is interchangeable. We always use the same LED module in as many products as possible to make it environmentally friendly.
- Sustainability - The components of the luminaires must be able to be bought later.
LedStore's innovative CCT led family of luminaires has been entered in both the International Architecture & Design Awards 2023 and the A'Design Award 2023!
The results were gold and bronze in the lighting design category!
WINNING INNOVATION IN PARTS
All of the above are features of CCT spots. For example, we still have in stock LED circuits from products manufactured 10 years ago. This way, the customer is assured of a long availability of spare parts. The CCT led luminaire product family was initially launched with 10 luminaires, but since then the family has expanded and evolved. Today, the family consists of 55 products:
- 35 different CCT led spots, the development of which started in 2018 and the family has been launched in 2019
- 10 different CCT Led panels, development started in 2019 and the family has been launched in 2020
- 10 different CCT Led strip lights, which started development in 2019 and will be released in 2020
All-in-one system. Choose your CCT adjustable led luminaire of your choice. All products have high quality: colour rendering CRI 98 and a 5-7 year warranty.
WHAT IS THE REAL INNOVATION HERE?
There have been CCT lights on the market for a few years now, but all of them have used only pre-fixed switches, with a CRI of around 80. These products have also often been made of plastic, or thin sheet metal, with poor colour rendering. It's okay for customers to be free to choose the shade of light during installation, but why stop there?
"I wanted to make sure that when the interior changes, when new art is added to the wall or the carpet changes colour, the luminaires always bring out the best in the objects. So I designed a whole range of down lights that are beautiful, long-lasting, freely usable in any smart lighting system and with the highest possible lighting quality, CRI98. The luminaires are easy to install, and because they are low-voltage and have plug n play connectors, so no compromises!"
- Janne Halttu
TWO INSTALLATION METHODS
Basic:
Standard, where the luminaire comes with a transformer with a 3-position switch. The switch allows you to select a light temperature of 2900K/4000/5500K at the installation stage. The luminaire is TRIAC dimmable. The Led luminaires can be installed in chains.
Customizable:
Freely selectable from 2900-5500K. Selection is done by the desired lighting control system such as ZIgbee, DALI2, Z-Wave, etc. All lights are 24VDC parallel connected. Easy to add/remove Led lights. That is, the luminaire is purchased "Without its own transformer" and the luminaires are connected in parallel to one group transformer. This way all the luminaires behind the transformer are controlled by one single group and the CCT colour temperature of the luminaires can be freely adjusted and dimmed.
ACCESSORIES FOR THE PRODUCT FAMILY
The CCT product family also includes a complete IP54, pull-protected cabling kit with a 3 metre intermediate cable, and a choice of 3-piece or 6-piece splitter.
You can also use your own 3 pole cable for installation.
WHAT IS A COLOUR TEMPERATURE ADJUSTABLE LUMINAIRE?
A CCT-led light is a luminaire that allows you to change the colour temperature of white light. The range depends on the led luminaire, but can be as low as 2500K - 6500K.
The changes in colour temperature, which are clearly visible to the eye, range from yellowish light to bluish light. A temperature-controlled LED light changes the hue of the light so that the luminaire itself always has two LED circuits in parallel; cold and warm.
When the mixing ratio of the two is changed with a control, the colour temperature of the light changes. In addition to the possibility of changing the colour temperature of the light, the luminaires are dimmable.
Different materials and colours react differently to different light spectrums. It is very important to find the right colour temperature to suit your needs.
