Back to Nature with Spectrum & Locus Adjustment (SLA)

SLA (Spectrum & Locus Adjustment) – The innovative Lightspot technology for precise definition of spectrum and color temperature.

The light spectrum changes continuously from dawn to sunset. To ensure natural and healthy lighting with sun-like spectra, LEDs with different color temperatures are usually combined. However, if, for example, warm white light (2700 K) and cool white light (6500 K) is mixed, this does not result in a "true" neutral white with 4000 K.

The resulting mixed light merely suggests to our eyes that it lies between warm white and cold white - like how the human eye can be made to believe that a mixture of red and green light is yellow.

Lightspot's SLA technology makes it possible to produce any desired color temperature with a spectral distribution that lies on the blackbody curve. Or to put it another way: the correlated color temperature practically becomes a real one again: CCT = CT.

 SLA technology is therefore perfectly suited to generating LED light with the optimum spectrum for any time of day. But it's not just the spectrum and color temperature that always match perfectly – all Lightspot LEDs that produce physiological light can offer optimum color rendering across the entire range of test colors from R 1 to R 15 (this corresponds to Re)!

The color rendering index for the SOL and PW series is CRI/Re> 98 for all available light colors.

The main difference between the SOL and PW series is the extended non-visual component in the near infrared (in PW). This makes the SOL ideal for all areas where, in addition to a broadband spectrum and outstanding color rendering is also increasingly about brightness and energy efficiency. The PW series is recommended the best physiological quality of light is required that can be achieved with LEDs today.
