LED Technology is not just about efficiency, power and light color temperature. Luminous flux performance over lifetime and color rendering index, accordingly the spectrum, are important as well. A lot of people recognize cheap LED versions in any shops or retail stores that seem to be bluish and illuminate the space quite palely.

The manufacturing process is accompanied by variations in material and action itself. The results are white light LEDs with different characteristics. Binning systems have been introduced to support the performance of LEDs and LED products. Binning is focusing on LEDs chromaticity (light color) or luminous flux (brightness) and can be described as the grouping of the LEDs into samples with the same or closest light color or brightness.

LED Light Color – Binning System.

In a nutshell, recent studies tested different compositions of lighting spectra and found an influence on human condition. People who are sensitive to their surroundings tend to complain about headache, dizziness and even nausea when exposed to imbalanced spectra. Long term exposition is even expected to have a negative impact on human health. When buying LED light sources, retrofit kits and products have a look at the CRI or spectrum. The more balanced, the better for the people working under it.
