Spectrum and Color
Useful for evaluating light quality, comparing fixtures, shaping mood and feel, and recreating looks more consistently.

Illuminance
Useful for measuring light levels in technical, production, stage, studio, and architectural workflows.

Flicker Analysis
Useful for identifying problematic light sources, analyzing flicker behavior, and reducing the risk of rolling artifacts or poor footage.

Typical Use Cases
