Watts to Lumens Converter
How bright is a 60-watt bulb, and which LED matches it? Convert watts to lumens for each bulb type.
How to use the Watts to Lumens Converter
- Enter the bulb wattage.
- Choose the bulb type.
- Read the lumens and equivalent wattage for other bulb types.
How it works
Lumens = watts × luminous efficacy. Incandescent bulbs give about 15 lumens per watt, halogens about 18, CFLs about 60 and LEDs about 90. A traditional 60 W incandescent produces about 800 lumens, so an LED of only 8–9 W gives the same light.
