Since there is daily powercut in my location.
This emergency light is very useful and helpful.
it is build with powerful LED lights which works continuously for average 4 to 5 hours and charging time takes 3 hours.
it has very good battery which is lead acid and capacity is very good.
it can be plugged to power outlet and light can be turned on, so that it turns on immidiately when power goes off.
I bought this for rs: 1750 one year ago and now the price may vary.
it is good quality product with long duarability.
Since it is lead acid battery just distilled water is uses when battery performance becomes low.
