How Much Energy Do LED Light Bulbs Really Save?

LED lightbulbs are efficient compared to traditional incandescent lighting or even fluorescent options.

You’ve probably asked yourself: how much energy do LED light bulbs really save? For an accurate answer, it’s important to understand that energy savings run far beyond the simple total amount of energy consumed by a single fixture with an LED bulb. Let’s take a look at some of the information about LED bulbs, and how much energy they really save.

LED vs. Incandescent: A Clear Choice When it Comes to Saving Energy

In this day and age, LEDs have surpassed incandescent bulbs as a preferable option. Let’s start off with this simple statistic: incandescent consume more than six times as much energy as an incandescent bulb. Not only that, incandescent bulbs require replacement far more often than LEDs because their lifespan is about 50 times shorter on average.

When we take that figure, we can do some key head-to-head comparisons between LEDs and Incandescent bulbs.

LED Light Bulb

Incandescent Light Bulb




Primary cost



Cost to run second year



Cost to buy and run for 3 hrs/day for a year






Working out how much energy is saved by an LED means working backwards from operation cost to the national average for cost per unit of energy. The average price of electricity in the USA works out to about 12 cents per kilowatt.

Money to Killowatt-Hours for LEDs vs. Compact Fluorescent Bulbs

LEDs work out better in terms of energy savings over the long term compared to compact fluorescent bulbs. Let’s take a look at two quick stats that illustrate this.

Cost to operate 3 hours per day for one year:

  • LEDs: $2.81
  • Compact Fluorescents: $5.04
  • …at 12 cents by kilowatt-hour gives…
  • 23.5 kilowatt-hours for LEDs versus 42 kilowatt-hours for compact fluorescents.

Energy Savings for LEDs: The Bigger Picture Beyond Your Facility

LEDs are more durable than incandescent bulbs. That means that not only do you get to save money and energy on operating costs, you also get to save time that would otherwise be spent up on ladders replacing burnt out bulbs. When you think about the bigger energy picture, you have to remember that dynamos don’t need to work as hard to power LED bulbs. That means putting a dent in our dependency on coal fuel. The more efficient we are, the less energy needs to be spent harvesting coal in the first place in the long run.
