Old style incandescent light bulbs have an efficiency of about 10-17 lumens per watt, meaning they convert only 10-17% of the energy they consume into visible light, with the rest being lost as heat. This makes them much less efficient compared to newer LED light bulbs, which typically have efficiencies of 80-100 lumens per watt.
