LED light How Much Money Can LEDs Save, Anyway?You probably know that LEDs are efficient, long-lasting, bright, and even affordable. But do you have a grasp on exactly how much money you can save by switching to LED lighting?

Let’s compare a 9-watt LED to a 60-watt incandescent light bulb:

Assuming the cost of electricity is $0.10/kWh, the incandescent light bulb will cost you $300 in electricity over 50,000 hours. The LED will cost you $45. That amounts to $255 in savings for every 50,000 hours of use.

  1. Is the 9-watt LED as bright or cast its light as far as the 60-watt bulb? Even if you needed 3 there still seems to be a significant energy savings.

    • Ann, it depends on the 9-watt LED. You’re right though, even if you need more than one, the energy savings are so significant that it still makes a huge difference! The key to finding an LED that’s just as bright is to check the lumen output. 60 watt incandescent light bulbs emit about 800 lumens of light. (See this chart for more lumen ratings.) Philips now has their L Prize-winning LED on the market – that one consumes just 10 watts and does deliver the same amount of light output as a 60 watt incandescent. The L Prize winner was chosen by the U.S. Department of Energy, so you can be sure that LED will live up to its product claims! Again, the best thing to check for is lumen output. Hope this helps!

  2. […] Incandescents are a whole different story. Though they are obviously the cheapest up front, over time incandescents are much, much pricier. Each incandescent costs about $1, and lasts about 1,200 hours. So to get 50,000 hours of light, you’d be paying $42 just for the replacement bulbs. Add in the additional expenses from the inefficient energy use, and your incandescents could end up costing you hundreds of dollars more than LEDs!
