In our houses now days, at every place where a socket for plug is required, there are usually two different sockets, they differ in shape and they differ in their supply of electric voltage as well. One is usually for 220V while the other is for 110V. These two different voltages are required because some products require high power to function while others require lower. Products like television and vacuum cleaners require higher energy therefore they have to be plugged into 220V socket where as table lamps and many mobile charging devices require lower power therefore they are plugged in to 110V socket Signreen 50W Equivalent Halogen Bulbs B07C2DW7D3.
Lower the power consumed, more efficient the product is. We are living in an age where energy efficiency is given a consideration because of two reasons; one being that humans have noticed the outcome of their careless waste of energy as wasted energy always ends up in the form of heat energy and increases the average temperature of our environment, now resulting in global warming. It’s the selfish human act why ice-caps are melting, water level of the oceans is rising and we are running to make every specie of animal into an extinct memory to be placed and viewed in museums only. Another reason why energy efficient products are preferred is because they knock off a significant amount of cash from electricity bill back into our pockets
