Bulbs / Tube Light / CFL are kept ON during the night to keep the surrounding area lighted.  It is essential as lighted area offers security and mental relief.  However in most places such lights are often kept ON  even after day break  and are switched OFF only when somebody notices them resulting in wastage of electricity and correspondingly higher costs.  Also it is noticed that lights are not made ON even in the evening after dark as no one is available. Electro-Arts now offers a  simple, versatile as well as cost and energy efficient solution to this problem.  Twilight Switch offered by Electro-Arts  switches  the lights ON only when they are actually required.
