Lighting Technologies & Controls: Customized Solutions & Integrated Systems - Colour Filters & Diffusers
Colour has been an important component of architectural lighting designs since the days of candles and silk. We use ROSCOLUX range of filters, as most of the colors in the Rosco range have been created by designers over the years to achieve specific effects, and the range is extensive. By additive mixing using multiple sources and by using multiple filters in units, a virtually unlimited palette can be achieved. There is no need for an expensive RGB or RGBW lighting luminaires to acheive a specific one hue of lighting colour in your architectural lighting design, when there is a huge palette of colours in our filters range, that can be easily tested in actual application to ensure the final effect desired.
Filters Effect

|---|
Lighting designers mix or blend colors through an additive or subtractive process. Blending light beams of different colors on a surface is an additive process. Creating a colored beam by filtering white light is a subtractive process – the desired color is transmitted while the other wavelengths are absorbed (or “subtracted”). |
How does it works?
 |
|---|
A color filter functions by selectively transmitting or blocking (absorbing) spectral elements of a beam of white light emanating from a light source. For example, a Roscolux 27 Medium Red filter will allow red light frequencies to pass through and absorb blue and green. Of the radiant energy which is blocked, by far the largest part is absorbed by the filter as heat. This is why heat stability is a significant consideration in filter design. The heat created by the absorption of energy leads to degradation of the filter. |
Sample Project: Dynamic Filters

The design team wanted a dynamic water effect that would glow in front of the train station at night. Their design objective was to create a lighting landmark. Explore it.. |
