The Sekonic C-800 SpectroMaster is a high-precision, full-spectrum color meter designed for photographers and filmmakers to ensure accurate color rendering and matching across various light sources. It is uniquely capable of measuring LED, HMI, fluorescent, tungsten, natural light, and flash, and is currently the only handheld meter to include the Spectral Similarity Index (SSI) for comparing light sources based on their spectral distribution
