International EMC standards describe the measurement environment (setup, equipment, frequencies) and applicable limits for the electromagnetic emission testing of lighting equipment, including compact fluorescent lamps (CFLs). These standards consider the compact fluorescent lamp a ‘black box’. In order to better understand the emissions from this type of light source, the operation of the equi...

BACKGROUND With the fast growth in the market of fluorescent lamps, particularly compact fluorescent light, the associated risk of mercury exposure, which is an essential component in all types of fluorescent lamps, has received increasing public attention worldwide. Even low doses of mercury are toxic. OBJECTIVE To study the health consequences of occupational exposure to mercury in workers ...

The photostability of tretinoin tocoferil was investigated under irradiation with three kinds of lamps, i.e., a cool white fluorescent lamp, a UV-A fluorescent lamp and a D65 fluorescent lamp. A combination of the cool white fluorescent lamp and the UV-A fluorescent lamp, and the D65 lamp having relative spectral power distribution similar to that of direct daylight, correspond to options 2 and...
