Abstract : With the continuous surge in urban civilization, usage of lighting has increased by many folds. Typical industrial energy consumption by lighting would be 2 to 10 % depending on the kind of industry. Lighting is essential for working environment and has its role in safety, quality output and wellbeing of work force. Initial cost of lighting infrastructure would be 15 % when comparing with the overall life cycle cost. This paper compares the available lighting technologies with respect to parameters like Flux (lumen), luminous Efficacy (lumen per Watt), illuminance ( lumens / sq.Mtr) or (Lux), Colour rendering index etc., and at the same time on the different impacts it has over resource, air, soil and water. The paper discusses about the different approaches adopted for energy efficiency in lighting system keeping in mind also its impact over environment, cost and future technological development in this field.
