The Economic Feasibility Study of Light Emitting Diode (LED) Lamp Replacement for Rural Kerosene Lamps (Dhibari)

A million of people in India depend on kerosene based lamps, Dhibari, Lantern and candles for the purpose of lighting, because of non existence of electric network in harsh terrains and unreliable electricity supply. Due to this, they have spent a major part of their expenditure on lighting. In this paper a Light Emitting Diode (LED) Lamp is introduced with two modes of illumination, high and low. A illumination intensity of 7 lux and 0.64 lux of light output can be achieved by this LED lamp at 1 meter distance in high and low mode of illumination respectively. The LED lamp saves one third of expenditure on lighting as compared to Dhibari and Lantern.
