LED lighting

The future of lighting seems to be the energy efficient Light Emitting Diodes.

If the street lighting in Pune was to change over to using LED street lights,this is how it would pan out.Pune has about 1,50,000 street lights, most of them being 250 watts Sodium Vapour.At a special rate of Rs.2.90 / kW, the electricity the PMC coughs up is approximately Rs.11 lakhs per day and carbon emitted by these inefficient lights is nearly 161 tons.By using LED based street lights which consume 45 watts,the PMC will spend Rs.2 lakhs for equal effect and will be save about Rs.60-70 per point per month on maintenance costs.Along with this the city will be benefited reduced carbon emission of approximately 130 tons per night.The value of carbon units amounts to more than Rs.2 lakhs per day.This means the city would be lit up at no cost!
