Digital cameras see LED light differently than tungsten/daylight sources. Additionally cameras interpret these light sources differently from each other. Color temperature meters are unable to see the full spectrum and therefore do not work for the evaluation of LED light. Samples are only taken in three or four places of the spectrum (narrow band filters). Spectrum analysis and CRI values offer a serious step for evaluation, but usually do not include colors called R9, which is a very important and critical red value, and R13 – skin tone. Even expanded CRI evaluations do not offer reliable criteria.TLCI (Television Lighting Consistency Index), the new standard of the European Broadcasting Union (EBU), offers a better and more reliable base for the way studio cameras see LED light. These studio cameras usually work with three CCD sensors. Thus, the results are not really indicative for the way different CMOS cameras see LED color. Only practical tests with many different cameras and shooting different skin tones in reference light comparisons bring us closer to the target.

Focusing LED lights present special challenges regarding color distribution. Specially developed LED light sources in combination with our patented double-aspheric technology (recognized by the Oscar committee for Technical Achievement) have allowed us to provide five different dedolight DLED focusing LED light fixtures. All deliver perfect light distribution, the widest focusing range in the industry and allow the use of our unique line of light shaping accessories.

TLCI evaluation of theabove meentioned light with TLCI values 97 in bicolor version and its lowest color temperature 2629K.
In this field we have always offered the worldwide lowest and safest uv-value. With LED light sources an additional hazard can be found, caused by the unavoidable blue peak. New criteria have to be applied as in bio-hazard standard EN6247.
Our products comply with the requirements of bio-hazard standard EN6247 in the category of “exempt” (without any health hazard criteria).
