LED vs CFL vs Incandescent

Comparison

What is a Lumen? Lumens measure how much light you are getting from a bulb. More Lumens means you see a brighter light; fewer Lumens means you see a dimmer light. Rules of Thumb 100W Incandescent: 1600 Lumens 75W Incandescent: 1100 Lumens 60W Incandescent: 800 Lumens 40W Incandescent: 450 Lumens

Human Light Sensitivity
