Spectrum

With a standard LED light spectrum, the pupil diameter tends to be larger than in natural daylight for the same illuminance. Zumtobel Spectrum has modified the wavelengths of LED lighting to more closely match daylight. In the process, the intensities of the blue wavelengths are significantly reduced, while the azure wavelengths are increased.  Zumtobel Spectrum reduces the diameter and helps the pupil to remain in its natural size. This reduces the amount of light entering the eye and reduces the strain on the retina. The result: the eyes remain relaxed and do not tire as quickly. The technology was developed in collaboration with the Japanese semiconductor company Nichia, an inventor and one of the world’s largest manufacturers of LEDs. A patent application is currently being filed for the technological world premiere!

Spectrum key features:

• Positive effect on concentration
• The eye can relax more quickly and easily after strenuous visual tasks
• Available as a CCT version in a wide variety of Zumtobel fixtures.
