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.

Godox QT600III
The Godox QT600III is a 600Ws AC-powered studio monolight designed for high-volume shooting environments. Its third-generation design focuses on fast recycling — rated at under 0.05 seconds at full power — making it suited for fast-paced portrait, fashion, and product photography workflows.
The QT600III features a built-in 2.4GHz wireless receiver compatible with the Godox X system, allowing seamless integration into multi-light setups. Its durable construction and consistent output at various power levels make it a reliable workhorse for permanent and semi-permanent studio installations.
The spectral data collected here provides an objective view of the QT600III's color output, including color temperature and spectral distribution at its rated power settings.
