Luminous flux calibration facility with an integrating sphere has been installed at the National Metrology Institute of Turkey (UME) in order to realize lumen. A LabView-based computer-controlled electrical system has been developed to operate light sources and to control electrical parameters. Owing to the corrections of the sphere system, inner coating reflectance, spatial non-uniformity, self-absorption factor and interior temperature variations have been characterized. The overall uncertainty in luminous flux measurement has been determined with an uncertainty of 1.14% (k = 2) in the range between 5–5000 lm
