1. What is an LED to Incandescent Watt Calculator?

Definition: This calculator converts incandescent bulb wattage to the equivalent LED wattage that would produce similar brightness.

Purpose: It helps consumers choose energy-efficient LED bulbs that match the brightness of their old incandescent bulbs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• LED Watts — Power consumption of LED bulb
• Incandescent Watts — Power consumption of traditional bulb

Explanation: LED bulbs typically use about 10% of the power of incandescent bulbs to produce the same amount of light.

3. Importance of Wattage Conversion

Details: Proper conversion helps in selecting energy-efficient lighting while maintaining desired brightness levels, reducing electricity costs.

4. Using the Calculator

Tips: Enter the wattage of your current incandescent bulb to find the equivalent LED wattage. Value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Is the 10:1 ratio always accurate?
A: It's a general rule. Some high-efficiency LEDs may use even less power, while others might need slightly more.

Q2: What about lumens?
A: For precise comparison, check lumens (brightness) rather than just wattage, as this varies between manufacturers.

Q3: Why do LEDs use less power?
A: LEDs are more efficient because they convert more electricity into light rather than heat.

Q4: Can I use this for halogen bulbs?
A: Halogens are slightly more efficient than incandescent; use about 7:1 ratio instead of 10:1.

Q5: How much energy can I save?
A: Switching from 60W incandescent to 6W LED can save about $7 per bulb annually (at 3 hrs/day use).
