For example, a 100 W incandescent bulb produces about 1,600 lumens, for an efficiency of 1,600/100 = 16 lumens per watt. A halogen bulb, on the other hand, consumes only 72 watts for the same amount of brightness, making its efficiency 1,600/72 = 22 lumens per watt. A CFL bulb ...

On average, an LED bulb can produce around 70-100 lumens per watt. This means that a 10-watt LED bulb can emit 700-1000 lumens, providing a level of brightness comparable to a 60-watt incandescent bulb. This significant difference in efficiency showcases the superiority of LED technology. ...
watts = lumens ÷ (lumens per watt) What is the (lm/W) figure? lm/W stands forlumens per wattand is a unit measuring luminous efficacy and energy efficiency - how much visible light is produced for a given amount of electricity. As an example, a 60W incandescent light bulb may produce...
a 100-watt bulb would be reliably brighter, and so on and so forth. Today, that’s no longer the case. LEDs, fluorescents, and more-efficient incandescents all have varying levels of wattage, and that wattage is no longer tied to brightness. Which is brighter today, a 40-watt fluoresce...
Old technology bulbs had an efficiency of 15 lumens per watt. Now LED bulbs typically offer 70 to 100lumens per watt. Therefore LED bulbs are five to six times more efficient in producing lights compared to old incandescent bulbs. So you can use 5:1/ 6:1 ratio while replacing old ...

At maximum efficiency, 683 lumens can be "harvested" from 1 watt (W) of power. However, a typical 100-W incandescent light bulb is good for only about 17 lumens per watt. This gives an efficiency of only (17/683) = 0.0249 = 2.49 percent. Newer light-emitting diode (LED) bulbs are...
