1. What is LED Savings Calculation?

The LED savings calculation estimates the cost savings when switching from fluorescent to LED lighting by comparing energy consumption differences over the lifetime of the LED product.

2. How Does the Calculator Work?

The calculator uses the LED savings equation:

Where:

• Energy Diff — Difference in energy consumption between fluorescent and LED (kWh)
• Price — Cost per kilowatt-hour of electricity (USD/kWh)
• Lifetime — Operational lifetime of the LED product (hours)

Explanation: The equation calculates total savings by multiplying the per-hour savings by the total operational lifetime.

3. Importance of LED Savings Calculation

Details: Calculating potential savings helps justify the upfront cost of LED conversion projects and demonstrates long-term cost benefits.

4. Using the Calculator

Tips: Enter the energy difference between your current and proposed lighting (kWh), your electricity price (USD/kWh), and the expected lifetime of the LED product (hours).

5. Frequently Asked Questions (FAQ)

Q1: How do I find the energy difference?
A: Subtract the LED wattage from the fluorescent wattage and divide by 1000 to get kWh difference.

Q2: What's a typical LED lifetime?
A: Quality LED products typically last 25,000-50,000 hours (about 3-6 years of 24/7 operation).

Q3: Should I include maintenance savings?
A: This calculator shows energy savings only. Additional savings come from reduced replacement and maintenance costs.

Q4: How accurate is this calculation?
A: It provides a basic estimate. For precise calculations, consider duty cycles, dimming, and environmental factors.

Q5: Can I use this for commercial projects?
A: Yes, but for large projects, a detailed lighting audit may be needed for accurate projections.
