Take a measurement

Measure your lights with Spectrum Genius Studio for parameters including Television Lighting Consistency Index (TLCI), White Balance, Exposure Compensation, ISO, TLMF, etc.

Television Lighting Consistency Index

The Television Lighting Consistency Index, developed by the European Broadcasting Union (EBU), is a new evaluation standard for studio lights and luminaries. TLCI scores lights in five different categories ranging from the poorest quality (85). A score of 90 is widely regarded as the minimum for television use.

The ultimate tool to test studio light sources

Combined with the Lighting Passport spectrometer, Spectrum Genius Studio is the most versatile tool to help you monitor studio lights or luminaries.


The Television Ligting Consistency Index helps evaluating lights and liminairies with a score on a scale from 0 to 100.

White Balance

Set your target CCT and use the color chart to adjust your image or photograph to specific or neutral colors.

Exposure Compensation

Use the built-in scale to adjust the exposure and optimize the quality of your image.


The Television Matching Factor allows users to use Fresnel or Flood Light as a reference for calculations.


ISO, Aperture & Shutter

Use Spectrum Genius Studio to set your Photo-Sensibility (ISO), Aperture and Shutter parameters.

Colorchecker Chart

Use the chart to visualize the difference between the reference and the measured light source as well as the Q value.

Advice for Colorists

Use the Avdvice for Colorists guide to adjust your lightness, chromaticity and hue for 12 different color sectors.

Smart Filter

Set your target color temperature and SGS will provide filter suggestions to change the color temperature of your luminaries.

Exposure Compensation

With Spectrum Genius Studio, adjust your exposure using the built-in scale to optimize the quality of your work. Set your ISO, Aperture and Shutter parameters and let the app do the work.

The ability to measure color and to instantly compute color metrics ranging from RA (CRI), R1-15, CQS and GAI, to the compliance with ANSI and IES colorimetry standards, and to the new TM-30 metrics, is in my opinion an essential part of lighting practice for everyone on the industry. I have owned a spectrometer since 2013 and cannot imagine working without one.
