Detailed explanation-1: -Lumens measure how much light you are getting from a bulb. More lumens means it’s a brighter light; fewer lumens means it’s a dimmer light. Lumens let you buy the amount of light you want. So when buying light bulbs, think lumens, not watts.
Detailed explanation-2: -Halogen, incandescent and fluorescent all product different types of light.
Detailed explanation-3: -Lumens = Light Output. In simple terms, Lumens (denoted by lm) are a measure of the total amount of visible light (to the human eye) from a lamp or light source. The higher the lumen rating the “brighter” the lamp will appear.
Detailed explanation-4: -Depending on the bulb and the manufacturer, LED technology typically produces 75-110 lumens/watt. So, LEDs are generally about 7 times more efficient at producing light than incandescent bulbs.
