The demand for energy in form of electricity is increasing across the world. The estimated consumption of electricity which was 13250 Twh (Terawatt Hours) in 2007 is expected to rise to 40000 Twh in 2040. With increasing focus on generating electricity from green sources, the gap between electricity supply and demand will grow even larger. If the gap between demand and supply is not closed in a cost effective manner, either the price of electricity to the end consumers will go up or the governments across the word will have to subsidize it. In both cases, the BOP segment which already has a limited access to electricity will continue to be deprived of access to reliable and affordable electricity. Trying to close this demand-supply gap using fossil fuels by increasing supply will have disastrous consequences on climate, which will again affect the BOP segment the most. To close this gap without affecting the quality of life and not much investment, it is also important to improve on the demand side of electricity consumption.

Use of energy efficient lighting
A major portion of electricity generated today is lost because of use of inefficient appliances and lightings. Use of energy efficient appliances and lightings can greatly reduce peak energy load and significantly increase the utilization of available power without having to invest in expensive electricity generation facilities. Around the world the household and commercial sector accounts for around a third of electricity usage and lighting is almost a third of that. Majority of lighting is obtained from incandescent bulbs. Based on a 100 year old technology, the incandescent bulbs converts only 5% of the electric energy into light and waste the rest as heat. A huge amount of savings in electricity consumption can come simply from use of efficient lighting by all sections of customers, both BOP and non-BOP.
From the energy saved by using efficient lighting India would be able to electrify 41 million more homes, and South Africa 8 million homes, without making any new investments in electricity generation.
Lightings are required by all, the process to move away from incandescent bulbs is very easy, switching cost is relatively low, and consumers can see immediate savings with lower electric bills. These incentives should help quick adoption of efficient lighting by all customer segments BOP and non-BOP. Also the grid connected BOP customers use electricity mainly for lighting so compared to development of other efficient appliances, development and easy availability of efficient lighting will help them the most. Use of efficient lighting will also help spread the use of solar powered to off-grid BOP consumers as relatively smaller, cheaper and portable solar panels and batteries can be used to get the same amount of light.

Target Market: All geographies and all consumer segments
A market analysis report by US Global Industry Analysts Inc estimates that by 2018, the global market for lighting fixtures will exceed US USD 121 billion and the market for lighting controls will be USD 8 billion. Countries around the world are beginning to phase out inefficient incandescent lamps by enforcing mandatory minimum energy performance standards for lighting. Companies competing in lighting industry can capture a larger share of lighting market by designing energy efficient lighting fixtures which meet the prescribed energy performance standards.

Innovation: Lighting fixtures based on LED (Light Emitting Diodes) technologies
CFL (Compact Fluorescent Lamps) and LED are the two technologies that have emerged to replace the incandescent bulbs. CFLs which are simply efficient miniature versions of full-sized fluorescents have gone out of favor because of the mercury content in them. The latest invention in lighting, LEDs or Solid State Lighting are more energy efficient than CFLs, have no environmental impact and have a very long life. LED light have an estimated
