An energy-saving lamp converts five times more energy into light than an ordinary light bulb. 25% of the consumed energy is converted into light.
An ordinary light bulb converts 95% of the power it consumes into heat and only 5% into light.
Example: A 100 W incandescent bulb can be replaced by a 20 W energy-saving lamp.
