Solar LED Lantern

Model: Tejas

These lanterns are a viable solution to replace Kerosene Lamps. Kerosene lamps are costly, inefficient, and provide poor lighting. It can be charged by solar panel and is AC grid compatible for emergencies

It is cost effective and long lasting as compared to earlier solar lighting systems. We have developed it in such a simple way that a village person can operate & maintain this after short training. Uses the world’s most efficient LEDs when fully charged it will provide up to 12 hours of bright light. The lamp gives an even white light that is projected at wide angle ‐ it is able to effectively illuminate a rural household with a room size of 4m x 4m.

It is 8 ‐ 10 times brighter than a kerosene lantern and 30 ‐ 50% more efficient than fluorescent lights. Though there is subsidy provided by the government on Kerosene still kerosene lamp is expensive as compared to the solar lighting system that we have developed. Based on our calculation we assure that the pay back period for the system is approx 1½ year.
