Sekonic SPECTROMETER C-800 ( 401-800)
The Sekonic C-800-U Spectromaster is a full-spectrum color and illuminance meter designed for photographers, cinematographers, and lighting professionals. It delivers unmatched precision in measuring LED, HMI, fluorescent, and electronic flash lighting.
Featuring a high-resolution CMOS sensor, it captures spectral spikes for superior color accuracy. Unlike other meters, the C-800-U provides direct values for major light sources and lens filters, simplifying color correction and speeding up post-production workflows.
It’s the only meter with SSI (Spectral Similarity Index), developed by the Academy of Motion Picture Arts and Sciences, allowing professionals to compare and score light sources based on spectral performance.
Key Features
✔ Full-Spectrum Measurement – Accurately measures LED, HMI, fluorescent, flash, and mixed lighting
✔ Advanced Color Metrics – Supports CRI, TLCI, TLMF, TM-30-18, and SSI for industry-standard analysis
✔ RGB & Multi-Color LED Matching – Measures (x, y) chromaticity coordinates, hue, and saturation for perfect LED light matching
✔ Real-Time Spectral Comparison – Compare light sources instantly for consistent color rendering
✔ Direct Brand-Specific Values – Simplifies color correction for major light and filter brands
✔ High-Speed Flash Measurement – Captures flash durations from 1/500s to 1s
✔ Multiple Display Modes – Includes spectral graphs, CRI, TM-30, SSI, TLCI/TLMF, and white balance correction
✔ USB-Powered & Portable – Runs on 2x AA batteries or USB bus power
