In Laos, power cut is a common problem whether it is a rural area or an urban lone. Besides, this common problem, there are many places which suffer from insufficient voltage supply. Therefore, such conditions lead to suspension in the work of offices, shops, hotels, schools, hospitals, etc. Solution to this problem (at Ileast to an extent) is emergency lights. Usually emergency light has a lamp fitted lin it of 60 watt and has a change over relay circuit-with the help of which as soon as the normal current stops, lamp of this emergency light lights up. When jthe normal current gets back, relay lamp stops and the circuit get disconnected 'as well. A battery and a battery charging unit is also fitted into the unit and when emergency light is not required, it keeps getting charged.
