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.

Neewer CB300B
The Neewer CB300B is a 300W bi-color LED panel covering a color temperature range from 2700K to 6500K. Positioned in the mid-range segment, it offers competitive output and color rendering for its price point, making it accessible to independent filmmakers and content creators.
The CB300B supports DMX control and includes a digital display for direct parameter adjustment. The spectral data collected here allows an objective evaluation of its CRI, Duv, and illuminance performance across dimming levels.
