LED Revolution in Lighting -This presentation endeavors to give a fundamental outlook on why, where, where not and what’s of LED in the world of lighting. - LED lighting for general illumination - Where to use LED - Efficiency, cost economics and maintenance required - How to select the right LED luminaire? - Knowledge of LM 79, LM 80 EMI/EMC standards and certain thermal aspects - Verification after installation whether the luminary has been delivered as per the specifications promised

Application Efficacy, Cost, Cost of Electricity generation, Life, Maintenance, warrantee as compared to other efficient light sources such as T5, CFL, sodium vapour, induction lamp, etc. Use of lenses increases the usable efficiency So, application in street lights, industrial high bay, solar, table lamps, work bench, sign boards/hoardings, and other task lighting www.suvegelectronics.com
