How LED Lights Proved to be Energy Efficient

LED lights virtually produce no heat (limited to 80%) in the illuminating process, therefore they are relatively cool. Approximately 20% electric energy gets transformed to light energy in these bulbs. While in traditional bulbs, about 80% electric energy is lost as heat energy resulting on only 20% efficiency, that is, conversion to light energy.
