1. What is the LED Wattage Equation?

The LED Wattage Equation estimates the approximate power consumption of an LED light bulb based on its light output in lumens, assuming a typical efficiency of 90 lumens per watt.

2. How Does the Calculator Work?

The calculator uses the LED Wattage Equation:

\[ W = \frac{L}{90} \]

Where:

\( W \) — LED wattage (W)
\( L \) — Light output in lumens (lm)
90 — Typical LED efficiency (lm/W)

Explanation: The equation converts light output (lumens) to power consumption (watts) based on typical LED efficiency.

3. Importance of LED Wattage Calculation

Details: Calculating LED wattage helps in energy consumption estimation, cost analysis, and comparing the efficiency of different lighting options.

4. Using the Calculator

Tips: Enter the light output in lumens. The value must be valid (lumens > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why use 90 lm/W as the efficiency factor?
A: 90 lumens per watt is a typical efficiency for modern LED bulbs, though actual efficiency may vary between products.

Q2: How accurate is this calculation?
A: This provides an approximate estimation. Actual wattage may vary based on the specific LED product and its efficiency.

Q3: Can I use this for other light sources?
A: This calculation is specifically designed for LED lighting. Other light sources have different efficiency ratings.

Q4: What if my LED has a different efficiency?
A: For more precise calculations, use the actual efficiency rating provided by the manufacturer.

Q5: How does this help with energy savings?
A: By understanding the relationship between light output and power consumption, you can make informed decisions about energy-efficient lighting choices.
