Tunable white illuminant for warm and cold white.
The SL 20.2 LED luminaire offers tunable-white possibilities.
With this luminaire the colour temperature can be variably adjusted from warm white to neutral or cold white using a controller. The intelligent TW light source consists of two different colour LEDs to achieve different colour temperatures ranging from 2,700 to 5,000 K with brightness and chromaticity actually being stored in its own memory.
Colours are controlled via DALI DT8 ensuring a constant luminous flux and Colour Rendering Index (CRI) exceeding 83 over the entire range of 2,700 to 5,000 K. Dynamic lighting with adaptable correlated colour temperatures (known as CCT) offer opportunities to greatly enhance ambience, productivity, aesthetics.
It is often considered as an essential core element in human centric lighting (HCL). As chromaticity coordinates and brightness are constantly evaluated by the system a perfect match can always be achieved regardless of the Bin of the LED used.
