To replace the 100-watt light bulb with an LED, you will need a bulb that has at least 1200 lumens.

How do I replace my incandescent bulbs with LEDs?

Back in the day, 100-watt incandescent light bulbs produced between 1200 and 1600 lumens, depending on voltage and who made the bulb. They also emitted light in all directions.

To replace the 100-watt light bulb with an LED, you will need a bulb that has at least 1200 lumens.

The LED should also be omni-directional so the light illuminates in all directions.

If you are also looking for the same light color as the standard 100 watt incandescent, you will need a 2700 Kelvin LED. The 3000 Kelvin will be brighter and whiter than a standard incandescent.

Use the guide below to replace your incandescent light bulbs with LED:

  • Replace a 250 watt incandescent using an LED with at least 3600 lumens 
  • Replace a 150 watt incandescent using an LED with at least 2800 lumens 
  • Replace a 100 watt incandescent using an LED with at least 1600 lumens 
  • Replace a 75 watt incandescent using an LED with at least 1200 lumens 
  • Replace a 60 watt incandescent using an LED with at least 800 lumens 
  • Replace a 40 watt incandescent using an LED with at least 500 lumens 

We recommend trying a few LED bulbs before investing in LED. We know many customers who replaced a 100-watt incandescent with a 800-lumen LED and they tell us it appears to be brighter than their old bulbs.
