1. What is a Fluorescent to LED Savings Calculator?

Definition: This calculator estimates the cost savings when switching from fluorescent lighting to LED 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:

• \( W_{\text{fluor}} \) — Wattage of fluorescent fixture
• \( W_{\text{LED}} \) — Wattage of LED replacement
• \( \text{Hours} \) — Annual usage hours
• \( \text{Rate} \) — Electricity cost per kWh

Explanation: The difference in wattage multiplied by usage hours gives energy savings in watt-hours, which is converted to kWh and multiplied by the electricity rate.

3. Importance of Lighting Upgrade Calculation

Details: Calculating potential savings helps justify the upfront cost of LED bulbs and demonstrates their long-term cost-effectiveness.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: It provides a good estimate, but actual savings may vary based on real-world usage patterns and electricity rate changes.

Q2: What's a typical LED wattage replacement?
A: A 32W fluorescent tube can typically be replaced with a 16-18W LED tube for equivalent light output.

Q3: Should I include ballast wattage for fluorescents?
A: Yes, include the total system wattage (lamp + ballast) for accurate comparison.

Q4: How do I estimate annual usage hours?
A: For businesses: hours/day × days/week × weeks/year. For homes: average 3 hours/day × 365 days.

Q5: Does this include maintenance savings?
A: No, this only calculates energy savings. LEDs also last longer, reducing replacement costs.
