Introduction: In recent years, use of compact fluorescent lamps has increased in order to optimize energy consumption. The aim of this study was to evaluate the radiations of electromagnetic spectrum from usual compact fluorescent lamps.

Methods: In this study, 48 compact fluorescent lamps from different brands and cover (warm – cool) were selected. For studied lamps, operational factors consisted of: UVA, UVB illuminannce, intensities of electromagnetic field in very low frequency (VLF) and extremely low frequency (ELF) ranges were measured using calibrated devices.

Results: The results showed that intensities of electromagnetic fields and UVA were below the exposure limits, but UVB was above the exposure limits. UVA lamps based on different light color (cover) had significant difference (P =0.008), UVA radiation between companies had significant difference. (P<0.001). Difference between the intensities of electromagnetic fields based on manufacturer was significant (p<0.05).

Conclusion: According to the study, compact fluorescent lamps had different amounts of UVA, UVB and electromagnetic fields, and UVB was above the exposure limits. Therefore, it is recommended not to use these lamps as the local electric lightings source without shield at distances of less than one meter. Observing the safety notes against the radiation of electromagnetic spectrum, increasing the distance from the source, and training seems necessary.
