The light colour is also called colour temperature in Kelvin . The higher this value is, the colder (bluish) is the light. Lower values produce a warmer (yellowish) light.
In general we can only make a recommendation here.
for living rooms we recommend a warmer colour temperature similar to a classic light blub with approx. 2700 Kelvin.
A neutral white light with approx. 4000- 4700 Kelvin is suitable for work rooms, offices, medical rooms; this also promotes concentration.
Accent lighting and colorful effect lights can be realized with RGB LED bands. With this version the color can be set freely.
LED bands in RGB-W version are the most flexible solution, because an additional white LED is not only able to show accents but also lighting tasks can be fulfilled too.
