for same power, led brightens more than bulb

actually, Bulb and an LED are two totally different things...you may be knowing the full form of an LED (Light Emitting Diode). It is a diode which emits light when a particular unit of current is passed.

Using a bulb of low power instead of LED is not at all preferred since low powered Bulb will not produce as much light as an LED of same power...a bulb makes use of a lot of electrical energy to heat up the tungsten coil and only a small fraction of it is emitted as light. So, a lot of energy is wasted. But in case of an LED it used almost whole electrical energy passed through it to emit light energy. Therefore, an LED is a lot better than a Bulb in all aspects.
