The Physics of Light and Color - Color Temperature

WebLumens 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 are to light what. Pounds are to bananas. Gallons are to milk. Lumens let you buy the amount of light you want. So when buying light bulbs, think lumens, not watts. WebExplanation. If a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, the total luminous flux emitted into that angle is one lumen (1 cd·1 sr = 1 lm). Alternatively, an isotropic one-candela light-source emits a total luminous flux of exactly 4π lumens. If the source were partly covered by an ideal absorbing …
