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 three 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, up to 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 wiring 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 in 2023 participated:
International Architecture & Design Awards
A'Design Award
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.
