“Precision Spectral Measurement Beyond Broadband Metrics”

Belgralux is a specialist light measurement and analysis consultancy focused on greenhouse and controlled-environment agriculture. Our work centres on spectrally accurate, high-resolution measurement of horticultural lighting at crop level, combined with rigorous data analysis and transparent reporting. By treating light as a measurable physical parameter rather than an assumption, we support growers, researchers, and technology providers with objective insight that enables informed technical and commercial decisions.

Our measurement technology leverages high-performance spectrometers with broad spectral coverage and fine resolution, capturing light data across a wide range from ultraviolet through visible to near-infrared wavelengths. These instruments deliver spectral resolution on the order of a few nanometers, enabling precise discrimination of spectral features and accurate characterisation of light quality beyond simple intensity metrics — essential for detailed crop-level analysis.
