ENERGY EFFICIENT LIGHTING

In this study we explored technical details of two most efficient lighting sources i.e. LEDs and Induction lamps. In the absence of an effective regulatory body, there is no check on the quality of products being brought into Pakistan markets in this vast and emerging technological area. The push for lower cost drives lower quality solutions being introduced in the local market without technical due-diligence. This has resulted in an influx of poor quality light sources where the electronics, luminaire and spectral considerations are not considered. We investigated the technical parameters such as power consumption, power factor, power quality, luminosity, color rendering index (CRI), color temperature, spectral analysis, flicker, emission angle and optimal operating conditions for characterization of different fixtures and conducted technical audit of some available products to confirm the claims of the vendors / manufacturers.
