emergency lights are- very common nowadays but the problem with them is the supply time. most of them can lighten for maximum of 2 to 3 hours and some which works more than this are too much costly. i tried to develop it so that it can work for minimum of 5 hours at a low cost in price. for this i used different type of led lights and modified the circuit. this light is very easy to use and can be charged with any mobile charger. it provides light for 5 to 6 hours and is very handy. the light output is 650 lumens which is good enough to use in time of load shedding or power cuts. i have also added a charge indicater circuit which remains red at the time of charging and after full charge it turns green.
with some modern diagrams and additions in the circuit the charging time has been elapsed and it gets fully charged in just 1 hours only. i am sharing this for the first time on steemit and ever on any website later on after completion of the project i will bring this product to light.
