Common Scenarios
When purchasing LED bulbs, flashlights, or projectors, lumens are the key parameter. This tool helps you convert traditional incandescent watts to equivalent LED lumens and watts.
History & Background
The term "lumen" comes from Latin for light. In the mid-20th century, photometry defined the lumen as the luminous flux emitted by a point source of 1 candela over a solid angle of 1 steradian.
Conversion Details
Luminous flux (lm) measures the total visible light emitted. Watt (W) is electrical power. This tool provides an approximate estimate based on standard efficiencies.
When buying bulbs, lumens determine brightness, not just watts.
