/ SERVICES / LIGHTING FIXTURES
Our goniolaboratory serves in the measurements of light distribution curves of luminaires. We use five goniophotometers for different types of needs, so we keep the delivery time short - results in up to 24 hours. Our measuring equipment meets the requirements of international measurement standards. With our goniophotometers, we measure the spectral, angular and temporal light distribution curves and light efficiencies of luminaires. The measurement data is reported in standardized file format of EULUMDAT/IESNA files suitable for Dialux / Relux. We also report the results in a variety of ways according to your needs in separate pdf reports.
Maximum dimensions of luminaires are 50 kg and 2.9 m.
Our services according to following measurement specifications:
- EN 13032-1 Measurement of Photometric Data of Lamps and Luminaires
