What is SPECTRD?
SPECTRD is a spectral measurement database for cinema, video, and photo lighting fixtures.
Every fixture in the database has been measured using the same spectrometer, under the same controlled conditions — across multiple color temperatures and dimming levels. For each configuration, you get the key colorimetric data: CRI Ra, Duv, color temperature, and illuminance, along with spectral distribution graphs and color rendering charts.
The goal is straightforward: provide clear, comparable, real-world data to help cinematographers, photographers, and gaffers make better-informed decisions about the lights they use.
Browse by brand, pick a fixture, select a color temperature — the data is there.
