Goniophotometers, Integrating Spheres & Spectroradiometers

Precision lighting and photometric test instruments from LISUN, spanning full photometric characterisation — goniophotometry, integrating spheres, and spectroradiometry — through to accelerated LED life and driver aging testing to LM-80/LM-84, and photobiological and mechanical safety testing for lamps and luminaires. The right measurement tool depends on what you're actually answering: an integrating sphere gives fast, repeatable total luminous flux for production QC, while a goniophotometer is needed when the intensity distribution pattern itself matters, such as for street lighting or automotive applications. 42 products covering luminous flux, colour, and photobiological safety testing across R&D, compliance, and production environments.
