High efficiency lighting in industry and commercial buildings

The amount of energy used from lighting varies from industry to industry but, typically, lighting accounts for approximately 15% of the electrical load in industry. In offices, the lighting may account for 5O% of the electrical load. By having an understanding of the lamps, ballasts, luminaires and control options available today, as well as the techniques used to develop efficient lighting, lighting can be produced that is energy efficient, cost effective and yields a higher quality of light.
