Viso Systems

Description :

Simply measure beam angle, lumen, cri, colour temperature and lumen per watt with no expert knowledge required. The system is comprised of full spectra spectrometry and a 50K/sec sample power analyser giving you a professional measurement. The LightSpionTM comes with the “Viso Light Inspector” software that connects via USB to your computer.

EU Regulation EU No 1194/2012 requires directional light sources luminous flux to be measured within 90° or 120° cone. Luminous flux measurement is normally done at full 360° in all direction. But the new EU Regulation EU No 1194/2012 require that directional lamps are measured in a 90° or 120° cone, meaning that only light illuminated in the cone is calculated efficient luminous flux.

The Viso Light Inspector software v4.2 now supports limited spherical measurements making it easier than ever to test your light sources against the new standard.
