1. What is an LED Light Savings Calculator?

Definition: This calculator estimates the cost savings from switching to LED lighting compared to traditional lighting.

Purpose: It helps homeowners and businesses evaluate the financial benefits of upgrading to energy-efficient LED lighting.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W_{\text{old}} \) — Wattage of old light fixture
• \( W_{\text{LED}} \) — Wattage of LED replacement
• \( \text{Hours} \) — Daily or annual usage hours
• \( \text{Rate} \) — Electricity cost per kilowatt-hour

Explanation: The calculator determines the wattage difference, multiplies by usage time and electricity rate, then converts to kWh.

3. Importance of LED Savings Calculation

Details: Understanding potential savings helps justify the upfront cost of LED upgrades and demonstrates long-term benefits.

4. Using the Calculator

Tips: Enter the wattage of your current lights and LED replacements, daily/annual usage hours, and your electricity rate (default $0.12/kWh).

5. Frequently Asked Questions (FAQ)

Q1: What's a typical LED wattage replacement?
A: A 60W incandescent can often be replaced with a 9-12W LED bulb for similar brightness.

Q2: How do I find my electricity rate?
A: Check your utility bill - it's usually listed as "price per kWh" in the charges section.

Q3: Should I use daily or annual hours?
A: For annual savings, multiply daily usage by 365. For monthly, multiply by 30.

Q4: Do LEDs really save that much?
A: Yes! LEDs typically use 75-90% less energy and last 25 times longer than incandescent bulbs.

Q5: What other factors affect savings?
A: Consider bulb lifespan (fewer replacements), cooling costs (LEDs emit less heat), and potential utility rebates.
