How much do LED lights save?
When you consider that lighting can account for up to 25% of your electricity bill, knowing how to cut down on that one cost can make a big difference in your household budget. Imagine having a little extra money at the end of the year to do with what you please, instead of feeding the power plant.
With that in mind, let’s answer the question: How much do LED lights save?
There’s been a lot of talk in the last few years about switching one’s lighting from standard incandescent to compact fluorescent bulbs (CFL), and most recently to LED (light emitting diode) bulbs. But how much do LED lights save?
LED bulbs were originally designed for small, battery-powered items, but have since been expanded by bulb makers to cluster together up to 180 of the tiny LED bulbs on one standard sized lamp and then enclosed in a diffuser lenses and reflectors to give it a normal light bulb appearance.
One of the best things about LED light bulbs is that they last up to 10 times as long as CFLs and many more times longer than standard incandescent bulbs. They are also more durable, since they don’t have a filament, so they withstand more jarring or bumping. They also remain cooler than the other kinds of bulbs.
In terms of energy efficiency, this is where the LED bulbs shine, so to speak. They use from 1/3 to 1/30 the energy of incandescent or CFLs.
How much do LED lights save?
In a head-to-head comparison of LEDs, CFLs, and incandescent bulbs, the numbers are astounding. The up front costs of LED bulbs will scare some people into just sticking to their energy-guzzling incandescent bulbs, but in the long run, the numbers are staggering.
A 60-watt LED bulb will currently set you back about $35. The prices will likely come down significantly in the next few years as demand increases and technology improves.
But the first consideration is that this light bulb will last up 42 times longer than an incandescent, so that $1.25 light bulb will cost more than $50 in replacement costs in the long run. A CFL bulb that costs $4 will add up to $20 spent on replacements to equal the life span of the LED bulb.
The differences in money spent on the actual electricity is even wider: Over the 50,000-hour life of an LED bulb, the electricity cost will be only $50, while the CFL will cost $70 and the incandescent will cost $300 to run.
So the total costs over the lifetime of a 50,000-hour LED bulb, 5 CFL bulbs that have a lifespan of 10,000 hours each, and 42 incandescent bulbs with an estimated lifespan of 1,200 hours are:
Purchase price Electricity costs Total cost for 50k hours
LED $35.95 $50 $85.95
CFL $3.95 (x5) $70 $89.75
Incandescent $1.25 (x42) $300 $352.50
While a savings of $4 isn’t much compared to a CFL, the added factors of durability, lifespan, cool operating temperature, and convenience make it worth the added up front costs.
In the long run, however, the savings will be huge. Now that you know the answer to how much do LED lights save, if you were willing to bite the bullet and replace all of your bulbs today, you wouldn’t be buying any new light bulbs for many years and your electric bill would drop significantly right away.
