LED Watts Formula:
From: | To: |
Definition: This calculator converts the wattage of incandescent bulbs to the equivalent wattage in LED bulbs.
Purpose: It helps consumers and professionals determine the appropriate LED bulb wattage to replace traditional incandescent bulbs while maintaining similar brightness.
The calculator uses the formula:
Where:
Explanation: LED bulbs typically use about 1/10th the power of incandescent bulbs to produce the same amount of light (lumens).
Details: Proper conversion ensures energy savings while maintaining adequate lighting levels in your space.
Tips: Simply enter the wattage of your current incandescent bulb to find the equivalent LED wattage. The value must be > 0.
Q1: Why is the ratio 1:10 for LED to incandescent?
A: LED technology is about 10 times more efficient at converting electricity to light than incandescent bulbs.
Q2: Will the LED bulb be as bright?
A: Yes, a 10W LED produces similar brightness (lumens) as a 100W incandescent, but uses much less energy.
Q3: Are all LEDs exactly 10x more efficient?
A: This is an average ratio - some high-efficiency LEDs may be 12-15x more efficient, while others may be 8x.
Q4: How much energy will I save by switching?
A: You'll save about 90% on lighting energy costs for equivalent brightness.
Q5: Do I need to consider lumens too?
A: For precise matching, check lumens (brightness) as well, especially for task lighting.
