The use of solid-state lightings using energy saving lights such as light emitting diodes (LEDs), High Pressure Sodium Vapour (HPSV) and induction light in the illumination has represented a major technological breakthrough in recent years. Several recent studies focus on the development and performance of energy saving street lighting systems such as LED, induction etc. These modern lamps use electronic ballasts contain a switching power supply circuit typically operate in the range of 20kHz to 60kHz to achieve low power consumption in which may cause interference to communication equipment as well as health effect to human body, which is not an issue in traditional electromagnetic 60Hz ballasts. This paper investigates the electromagnetic and electric field exposure to human body from three street lights systems; LED, HPSV and Induction lights. The electromagnetic and electric field measurement are conducted in the laboratory that represents a controlled environment in which free from external factors or interferences. The electromagnetic and electric field exposure measurements are conducted using the Aaronia SPECTRAN hand held spectrum analyzer model NF-5030 on five streetlights from three different types in accordance to MS2230-2009 standard. The results presented in this paper can be utilized as references for measurement in open space that may have some interferences from other sources as well.
