Lumens vs. Watts

What are Lumens?

Watts measure the amount of energy required to light products, whereas lumens measure the amount of light produced. The more lumens in a light bulb, the brighter the light. 

For instance:

  • 40-watt incandescent bulb = 450 lumens
  • 60-watt incandescent bulb = 800 lumens
  • 75-watt incandescent bulb = 1100 lumens
  • 100-watt incandescent bulb = 1600 lumens

As of January 1, 2012 the traditional 100 watt incandescent light bulb is no longer being manufactured.  Of course this does mean that consumers will be unable to buy the  incandescent light bulb or that they will have to puchase compact florescent (CFL) bulbs.  The stores will not be removing incandescent bulbs from their shelves, their current inventory will still be available for sale until it is exhausted.

There will be similar standards for other types of light bulbs over the next several years.

75-watt incandescent light bulb will no longer be manufactured after January 1, 2013.

60-watt & 40-watt incandescent light bulb will no longer be manufactured after January 1, 2014.
