Example
Input: 60W vs 9W, 5h/day
Result: $14 saved/year
Step-by-Step Guide
- Old Wattage – Power of current bulb (e.g. 60W).
- LED Wattage – Power of replacement (e.g. 9W).
- Usage – Hours used per day.
- Calculate – Annual savings per bulb.
What is LED Savings Calculator: Lighting ROI?
The LED Savings Calculator quantifies the financial and energy benefits of upgrading lighting fixtures. LEDs consume significantly less power to produce the same light output compared to traditional incandescent bulbs. This tool projects cumulative savings over time.
How it Works
Savings are derived from the difference in wattage multiplied by usage.
Formula: $Savings = (OldWatts - NewWatts) \times Hours \times 365 / 1000 \times Rate$.
FAQ
Do LEDs really save that much?
Yes, they use 75-90% less energy.
Lumens vs Watts?
Buy based on Lumens (brightness), not Watts.
Lifespan?
LEDs last 25,000+ hours vs 1,000 for incandescent.
Heat?
LEDs run cool, reducing AC costs in summer.
CFLs?
LEDs are safer (no mercury) and more efficient than CFLs.
Conclusion
Replacing bulbs is one of the highest ROI home improvements. With a lifespan of 20+ years, LEDs pay for themselves in months and continue saving money for decades.
