Turnkey Goniophotometer Testing Laboratory
Delivering East Africa’s precision photometric testing infrastructure — a goniophotometer laboratory engineered to full international standards from a blank floor plan to operational facility.
Photometric testing laboratories are among the most technically demanding scientific environments to design and construct. A goniophotometer — used to measure the precise luminous intensity distribution, spectral power distribution, and efficiency of light sources and luminaires — requires an integration of mechanical precision, environmental control, electromagnetic isolation, and spatial accuracy that few engineering firms in the region are equipped to deliver.
Imperial East Africa executed this project as a complete turnkey scientific solution: taking full ownership from initial facility design through to equipment supply, installation, calibration, system commissioning, and comprehensive staff training. The result is a fully operational testing laboratory capable of producing internationally recognised photometric and spectroradiometric test reports compliant with IES LM-79 and CIE 121 standards.
Challenge
The client required a photometric and spectroradiometric testing facility capable of certifying lighting products to international standards — meeting the requirements of both IES LM-79 (the North American standard for electrical and photometric testing of solid-state lighting) and CIE 121 (the international standard for photometric measurements using goniophotometers).
Achieving this demanded far more than procuring a goniophotometer. It required a precisely controlled physical environment, mechanical integration that eliminates vibration and positional error to within fractions of a degree, electromagnetic shielding to prevent measurement interference, and a complete data acquisition and reporting system capable of producing audit-ready test documentation.
