Coloured light: RGBW luminaires
Some luminaires in our range are offered as RGBW luminaires.
These luminaires utilise four LEDs (red, green, blue and white) for
additive colour mixing. The option to modify the intensity of each
LED allows the rendering of millions of distinct colours. The added
white LED creates soft pastel colours as it impacts on the light
colour saturation.
RGBW luminaires therefore offer a broad range of colours and
a better white rendering than RGB luminaires.
Colour Rendering Index
At BEGA, the natural colour rendering of our luminaires is a priority.
The Colour Rendering Index (CRI) rates the natural quality of light
under a light source. Our luminaires with a CRI of 90 or higher
offer excellent colour rendering, meaning the colours appear
almost as natural as in daylight. That is an important feature for
applications in museums, art galleries or wherever precise colour
perception is essential. Our luminaires with a CRI of 80 also
deliver good colour rendering with outstanding efficiency and
are ideally suited for general use in interior spaces.
Colour consistency
White isn’t just white. Consistent and reliable light quality requires
the use of highest quality components.
We are very consistent in our approach for careful binning.
It requires the sorting and selection of the LEDs we use according
to strict criteria: colour temperature, luminous efficacy and
electrical characteristics. This precise binning ensures that our
luminaires offer a uniform light quality and colour consistency –
a very important factor for larger scale installations.
BEGA luminaires feature LED modules with a maximum colour
deviation of three MacAdam steps within the same module type,
denoting a high level colour consistency of the LEDs to ensure
a uniform and attractive light pattern.
These requirements are decisive considerations for high-quality
lighting systems in architecture and any application where
seamless and uniform lighting result is crucial.
