LED bulbs use much a lot less Electricity than halogen bulbs and previous as many as 50 moments longer than incandescent bulbs.
Large-ability LEDs can produce a A lot bigger light intensity and sometimes can deliver approximately a hundred lumen light per watt. Significant-power LEDs consume a good deal far more electricity and require a A lot increased latest than typical LEDs. Because of the amount of current being used by substantial-electrical power LEDs they deliver a substantial amount of thermal Electrical power.
