The artificial lighting used today in home and workplace have confirmed capability to induce skin problems, DNA damage, tumor formation as well as worsening arthritis, migraine and visual fati-gue by longer exposure of ultraviolet radiation from discharge lighting sources. In this paper an ignition-angle controller (IAC) is used to demonstrate the reliability of incandescent lamps (ILs) in comparison with discharge lighting feed by switching-mode supplies. Analysis of harmonic of the line-current flow consumed by the ignition-angle controller (IAC) circuit has shown that produc-tion of distorted rms currents does not produce hazard, because single harmonic distortion (SHD) values are keeping lower to 50%. As energy policy, the modern artificial lighting must be replaced by economical, stable and nonhazardous incandescent lamps (ILs)
