LED light bulbs are more efficient than incandescent lights bulbs. Incandescent bulbs produce light by heating a thin tungsten coil. This causes generation of a large amount of heat resulting in huge energy wastage. In case of LED lights, electrical energy passing through the semiconductor efficiently converts into light energy, with no production of heat. LED lights also have a longer life span, and are cold lighting options that reduce the risk of fire. LEDs can also work in both AC and DC modes. In addition, they are smaller, lightweight and resistant to breakage.
