Power Consumption Formula:
From: | To: |
Definition: This calculator estimates the total power consumption of an LED strip based on its length and power consumption per meter.
Purpose: It helps electrical engineers, lighting designers, and DIY enthusiasts determine the power requirements for LED lighting projects.
The calculator uses the formula:
Where:
Explanation: The total power is calculated by multiplying the length of the LED strip by its power consumption per meter.
Details: Proper power calculation ensures correct power supply selection, prevents overloading circuits, and helps estimate energy costs.
Tips: Enter the LED strip length in meters and power per meter (default 7.2W/m for typical 5050 LED strips). All values must be > 0.
Q1: What's a typical power consumption for LED strips?
A: Common values range from 4.8W/m (2835 LEDs) to 14.4W/m (high-density RGB strips).
Q2: Should I add extra capacity to the calculation?
A: Yes, it's recommended to add 20% buffer to the calculated value for safety.
Q3: Where can I find the power per meter specification?
A: Check the product datasheet or packaging of your LED strip.
Q4: Does this include power supply efficiency losses?
A: No, consider power supply efficiency (typically 85-90%) when sizing your power supply.
Q5: How does voltage affect the calculation?
A: The formula works for any voltage as long as you use the correct watts/meter value for your specific strip.
