LED Light Bulb Cost Per Year: Know How Much You Save With The Latest Technology!


Since the introduction of LED technology, it has become the number one option for energy efficiency and durability. Therefore, replacing your traditional light bulbs saves you a lot on electricity lighting bills. For instance, if you are running LED bulb with10 watts for 5 hours daily, it will cost $0.10 per kWh. The annual fee is thus equivalent to $ 1.83.

To calculate the total cost, enter the average number of hours the device uses daily. When the energy consumption is below 1 hour per day, use the decimal. For example, 40 minutes per day is 0.7. For the energy use (watts), place the average energy consumption of the device in watts. Price (kWh) is the total cost you are paying per kilowatt-hour on an average. 

For exact value, check the global electricity price or look at your electricity bills. Nonetheless, the comparison table below shows the approximate difference in their annual cost between LED and other traditional light bulbs. Check it for wise decision-making!

N/B: In the table, the assumption is that you are using the lights for 5 hours a day

Financially speaking, it is worthwhile buying the LED light bulb at a higher cost as it lessens your electricity bill in the long run. The cost of replacement is also minimized if not wholly taken off since the LED light has a longer lifetime of more than 20 years. They are also environmentally friendly because its mercury and lead-free. Overall, LED light bulbs offer the best option for energy savings and are much more superior to traditional lights we had been using for a while now.

How Much Does It Cost To Run An LED Light Bulb For 24 Hours?

Leaving your lights for 24 hours is not that costly, especially if you use LED energy-saving light bulbs. Yes, the cost might be slightly higher than your 5-hour daily use, but it won’t be close to what you might have spent on traditional lights. The total cost will be around 2.5 cents a day

Calculating the total cost is straightforward. For this case, let’s make an assumption that you are using a LED bulb equivalent to 10 watts at the expense of 10 cents per kWh of energy per hour in 24 hours. So, the cost is:

0.01(10 watts led equivalent/1000) kilowatts* 24 hours* 10 cents = approximately 2.5 cents in one day.

How Much Does It Cost To Run A LED Light Bulb In The UK?

If you light up your building or home for 10 hours per day in the UK, the cost of LED lighting is about £2.78 total average cost per year. The cost of purchasing an LED light bulb usually is £1.70 per year, and it uses £ 1.08 for electricity consumption, thus bringing your total cost to £2.78.

Electricity consumption and purchase cost annually are reviewed, and it is 12% cheaper to operate an LED light bulb than fluorescent energy-saving bulbs. In comparison, it’s 74% cheaper than its counterpart’s incandescent bulbs. So, over time, LED lighting is typically more cost-effective than traditional lighting.

Replacing your traditional lights with the red ones can save you up to £240 per year as a homeowner and even more as a business person. Furthermore, you benefit from a significant increase in productivity achieved due to healthy light emitted from LEDs.

Are LED Lights Cheaper To Run Than Regular Bulbs?

Running LED lights are way far much cheaper than regular bulbs like incandescent bulbs or CFL. Generally, LED bulbs consume only a fraction of the electricity that traditional light bulbs consume at a go. More so, they durable and can last you up to fifty times longer when you compare with the regular bulbs. Besides, it will run for years without any faults or problems as long as proper installation is done.

The total cost of switching to LED might be high, but it is worth it in the long run. You can save up to £5 per bulb yearly for making the changes. You might be hesitant to do so considering the upfront cost but notes that it will wrap off those online personal loans you usually take to cover your electricity bills.  

How Much Does It Cost To Run A 60-Watt Bulb For 1 Hour?

Let’s assume you have 60-watts incandescent light bulbs, and in your locality, one is paying 12 cents per kWh of energy. Now you want to know the equivalent cost that will amount to an hour to run your 60-watts bulb. The calculation will be;

0.06(60 watts over 1000) kilowatts * 1 hour *12 cents = 0.7 cents approximately in an hour.


Typically, a CFL or LED bulb consumes less than 25% of the total energy for the similar light power as the 60-watt incandescent. There is a chance for substantial savings because they run nonstop for about 70 to 100 hours for equal-cost energy. Also, note that the 60-watts incandescent light bulbs consume the same power as LED HD 37-inch quality TVs, which means the cost is similar when turned on.

Is It Cheaper To Leave LED Lights On?

While turning off the lights in most scenarios saves you energy, it depends mainly on the type of bulbs you use.  Sometimes it’s even cheaper to leave them on than to turn them off. Light-emitting diode or LED bulbs are not generally affected by being turned on or off at all. That’s what makes them the top energy savings lighting option. 

Yes, it’s even a great option when used with sensors that rely majorly on on/off operation. For example, the security or outdoor lights in our homes that light up all night long due to various reasons. The sensor will turn them off during day time. Remember, LED lights turn on at their full brightness instantly, unlike other types. As for halogens or incandescent lights, they need to be turned off immediately when not used to save up the electricity cost. Turn off CFL lights you are stepping out for more than 15 minutes.

How Do I Stop My LED Lights From Glowing?

There are various solutions you can use to stop the LED lights from glowing when turned off. You can either decide to replace the bulb, set up the earthed wiring or Zener diode, or use a CFL to seep off the extra voltage. Alternatively, you can use a neon indicator or talk to the LED lamp manufacturer.

But first, let’s understand what causes LED lights to glow when they are off. The problem is more associated with the electric current, so the lights themselves are of poor quality. The bulbs may not be affected, but the current is due to the neutral wire inside the circuit that doesn’t bond with the earth. Sometimes there might be an electric pick-up alongside the cable wire bring about via electromagnetic induction.

Do LED Lights Raise Electric Bills?

No, simply because LED lights use around 25 to 80 percent less energy if you compare with incandescent lights. Studies show that the annual average cost of 60 watts’ incandescent lights bulbs amounts to $4.80. On the other hand, the cost of 12W LED light bulbs, offering the similar light as a 60w incandescent light, cost $ 1.00 annually. Meaning it’s 75 percent less the energy that a 60 –watts incandescent light uses. Also, 72 percent less than a 43 watts’ halogen lights uses.

How Much Does A 1000W LED Cost?

The determinant factor of calculating the LED cost is the amount you pay in your home per kilowatt an hour. If in your locality you are producing $0.1559 kWh, the monthly calculation assuming your lights runs for 18 hours a day will be;

First, you need to divide your wattage by 1000, i.e., 1,000 kilowatts in 1 watt.

1*0.1559 * 18 *30 = $ 84.186 per month

What Are The Disadvantages Of LED Light Bulbs?

Indeed, the benefits of LED light bulbs outnumber its limitations. However, you need to be aware of the following disadvantages to be on the safe side:

1. The up-front cost is usually high

2. Possible transformer compatibility

3. The probability of color shift during its lifespan is there.

4. The performance standardization for LED bulbs has not yet been streamlined.

5. Overheating these bulbs can reduce their lifetime.


The LED light’s total cost per year is reasonably low. It will leave you wondering why you haven’t considered changing your traditional bulbs for such an extended period. It’s about time you embark on your journey of switching off to LED lighting. The product not only saves your electricity bill but offers quality lighting. They are also eco-friendly and durable.
