About this calculator
The LED vs Incandescent light bulb economy calculator is a useful tool for those who want to know how many units of energy can be saved by replacing incandescent bulbs with LED bulbs.
The used formula is simple: W_diff (LED and incandescent power difference) multiplied by h (usage hour) and divided by 1000, all multiplied by the energy tariff. This allows you to calculate the monthly or annual savings in real.
This calculator is especially useful for those planning a lighting project in their home or commercial location, as it allows you to calculate energy savings before making a decision.
In addition, choosing LED bulbs can help reduce your energy bill and contribute to environmental conservation.
