    Abstract
    Currently, most countries in the world have been interested to reduce the power consumption due to energy resources shortage. So, manufacturers excited to expand in lot of production of low-power LEDs for huge benefits that summarized in over age life span and the least power consumption. Standard Specifications evaluated few low power LEDs types compared to rapid production of lighting units which leads the shortage of technical datasheet in general. This aims to establish actual studies in this paper to stand and detect the performance requirements of low LED units. Light flicker phenomenon is one of the important power quality criteria of LEDs especially for interiors because of its effects on human healthy and so, causative factors on flickers must be studied and analyzed. Several meter systems have been established to measure flicker metrics (flicker index and percent flicker) of lighting units. Reference meter system (PNNL system) is one of these meters composed of portable measurement device which is simulated and designed in this paper to test low power LED samples in experimental procedure. Also, the measures are evaluated under Standards and compared with sample CFL unit. Also, the light flicker waveform of low frequency LEDs is investigated
