1. What is an LED vs Incandescent Calculator?

Definition: This calculator compares the energy costs between LED and incandescent bulbs based on their wattage, usage hours, and electricity rate.

Purpose: It helps consumers understand the cost savings of using energy-efficient LED lighting over traditional incandescent bulbs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Cost \) — Energy cost in dollars
• \( Watts \) — Power consumption of the bulb
• \( Hours \) — Duration of usage
• \( Rate \) — Electricity cost per kilowatt-hour

Explanation: The formula converts watts to kilowatts, multiplies by hours of use, then by the electricity rate to calculate total energy cost.

3. Importance of Energy Cost Comparison

Details: Understanding the cost difference helps in making informed decisions about lighting choices that can significantly reduce electricity bills.

4. Using the Calculator

Tips: Enter the wattage for both bulb types (default 10W LED vs 60W incandescent), hours of usage, and your electricity rate (default $0.12/kWh).

5. Frequently Asked Questions (FAQ)

Q1: Why compare LED and incandescent bulbs?
A: LEDs use significantly less energy (about 85% less) to produce the same light output, resulting in substantial cost savings.

Q2: What's a typical LED equivalent to a 60W incandescent?
A: About 8-12W LED bulb produces similar brightness to a 60W incandescent.

Q3: How do I find my electricity rate?
A: Check your utility bill - it's usually listed as cost per kilowatt-hour (kWh).

Q4: Does this include bulb replacement costs?
A: No, this only calculates energy costs. LEDs last much longer (25,000+ hours vs 1,000 for incandescent).

Q5: What other factors should I consider?
A: Light quality, color temperature, dimmability, and initial purchase price are also important factors.
