The present research aimed to investigate some lighting characteristics of six commercial compact fluorescent lamps (CFLs). The lighting characteristics such as spectral power distributions (SPDs), and spectral mismatch correction factor (SCF) to human response eye curve V(λ) have important roles on visual health effects of the lamps. A set up based on National Institute of standards of Egypt (NIS) Spectroradiometer ocean optics HR 2000 with uncertainty 4.7% and the photometric bench has been

Calculations of comparative analysis have been done for spectral mismatch correction factor (SCF) to human response curve V (λ). The spectral power distributions (SPDs) diagrams for the commercial compact lamps (CFLs) showed typical CFLs response, with a few narrow spectral peaks. The histogram for comparison of spectral mismatch factor shows the spectral mismatch factor for each CFL lamp and the degree of perfectly spectral matching with human response eye curve V (λ). Data analysis was performed and uncertainty model includes all parameters accompanied with the measurements are calculated.
