LED Conversion Calculator
Calculate energy savings, cost reductions, and environmental benefits when converting from traditional lighting to LED. Compare different bulb types and estimate payback periods.
Step 1: Current Lighting Setup
About Traditional Lighting
Incandescent bulbs are only 5-10% efficient, losing 90% of energy as heat. Halogens are slightly better at 15-20% efficiency. CFLs are about 25-35% efficient.
Step 2: LED Replacement Options
About LED Lighting
LEDs are 80-90% efficient, converting most energy to light. They last 15-25 times longer than incandescent bulbs and use 75-80% less energy for the same light output.

Lighting Technology Comparison
Comparison Details
LED bulbs provide the same light output (lumens) while using significantly less energy. A 9W LED produces about 800 lumens, equivalent to a 60W incandescent or 14W CFL bulb.
Cost & Energy Breakdown
Savings Calculation Formula
Annual Savings = (Current Wattage – LED Wattage) × Hours × Days × Rate × Bulbs
Calculate energy savings by comparing wattage differences, then multiply by usage hours, days per year, electricity rate, and number of bulbs. Include bulb replacement costs for accurate savings.
