1. What is an LED Strip Wattage Calculator?

Definition: This calculator estimates the total power consumption of LED strips based on their length and wattage per meter.

Purpose: It helps electricians, lighting designers, and DIYers determine power requirements for LED lighting installations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Total power (watts)
• \( L \) — Length of LED strip (meters)
• \( W \) — Wattage per meter (watts/meter)

Explanation: The strip length is multiplied by the power consumption per meter to get the total wattage.

3. Importance of LED Wattage Calculation

Details: Proper wattage calculation ensures correct power supply sizing, prevents overloads, and helps estimate energy costs.

4. Using the Calculator

Tips: Enter the strip length in meters and wattage per meter (default 7.2W/m for standard RGB strips). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical wattage for LED strips?
A: Standard RGB strips are about 7.2W/m, while high-density or white strips can be 14.4W/m or more.

Q2: How do I find my strip's wattage per meter?
A: Check the product specifications or divide the power supply wattage by the strip length.

Q3: Should I add extra capacity?
A: Yes, power supplies should be rated for 20% more than the calculated wattage for safety.

Q4: Does this include voltage drop calculations?
A: No, this is total wattage only. For long runs (>5m), consider voltage drop separately.

Q5: How does this relate to amperage?
A: For 12V systems, divide total watts by 12 to get amps (e.g., 72W ÷ 12V = 6A).
