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 Q4
The Neewer Q4 is a compact battery-powered studio flash aimed at photographers who need a lightweight strobe for outdoor portraits, events, and small mobile setups. Its portable format and integrated battery make it easier to deploy on location than traditional AC-powered flash heads.
Positioned as an accessible option in the portable flash segment, the Q4 is designed to balance affordability, usable output, and practical field convenience. It is typically used with softboxes, reflectors, or umbrellas in fast setups where transport and speed matter as much as raw power.
