Why switch to LED light bulbs?
An LED bulb typically uses up to 90% less energy than a regular incandescent or halogen bulb and lasts far longer. That saves you money on your electricity bill and on replacing bulbs, and it cuts the CO₂ released by generating the power.
The most common light bulb alternatives
Incandescent bulbs were the standard home bulb for decades but waste most of their energy as heat, and have been phased out in many countries.
Halogen bulbs are a variation on the incandescent and use roughly 20–30% less energy, but have a shorter life than CFL and LED bulbs.
CFL bulbs (compact fluorescent lamps) use roughly 60–80% less energy than incandescent bulbs and last much longer.
Working out your CO₂ saving
The CO₂ figure uses a conversion factor of 0.542 kg of CO₂ for every kWh of electricity saved.

LED Savings Calculator
The LED Savings Calculator is a simple online tool that helps you figure out how much money you can save by switching from regular light bulbs to energy-efficient LED bulbs. This calculator helps you estimate potential savings by upgrading your home’s lighting, lowering your office’s energy use, or reducing your electricity bills.
How to Use the LED Savings Calculator
Enter the wattage of your existing bulbs and the wattage of the LED bulbs you want to use. Add the number of bulbs, average daily usage hours, electricity cost per kilowatt-hour (kWh), and estimated purchase cost of the LED bulbs. These details help the calculator estimate your electricity savings and how long it might take to recover the initial cost.
Calculate Electricity Savings
LED lights generally use less electricity than traditional incandescent bulbs while providing comparable brightness. You can estimate potential energy savings over time by comparing the wattage of your current bulbs with that of LED alternatives.
Your actual savings will depend on bulb wattage, required brightness, usage hours, and your electricity rate.
Estimate How Much Money You’ll Save
The LED Savings Calculator helps you compare the running costs of traditional bulbs and LED lighting. You can estimate daily, monthly, and yearly savings to understand how switching to LED bulbs might reduce your electricity expenses.
Calculate the Payback Period for LED Bulbs
Although LED bulbs may cost more initially than some traditional bulbs, their lower electricity consumption can help recover the purchase cost over time. The calculator helps estimate how long it might take for your energy savings to offset the additional cost of LED lighting.
Why Should You Use an LED Savings Calculator?
- Lower your electricity bill: Estimate how much you could save by switching to LED bulbs.
- Compare energy use: Understand the difference between traditional bulbs and LED lighting.
- Plan your budget: Estimate monthly and yearly electricity savings.
- Evaluate your investment: Calculate how long it might take for LED bulbs to pay for themselves.
- Make energy-efficient choices: Identify opportunities to reduce electricity consumption.
Ways to Maximize LED Lighting Savings
Choose LED bulbs with the right brightness and color temperature for each room. Compare both wattage and lumens instead of judging bulbs by wattage alone. To maximize savings, replace frequently used traditional bulbs first and choose quality LED products with reliable energy-efficiency information.
Keep in mind that your savings will depend on bulb prices, electricity rates, usage patterns, and the type of lighting being replaced.
Calculate Your Potential LED Savings
Use the LED Savings Calculator to estimate electricity savings, compare lighting costs, and determine whether switching to LED bulbs makes financial sense for your home or business. When several lights are used every day, even small reductions in energy consumption can add up over time.
