Om dette verktøyet

This watts to lumens converter helps you calculate the brightness (in lumens) of light bulbs based on their power consumption (in watts) and bulb type. Different bulb technologies have different efficiency levels, so the same wattage produces different amounts of light. Our tool uses industry-standard conversion factors for incandescent, LED, CFL, and halogen bulbs to provide accurate lumens calculations. Simply enter the wattage, select the bulb type, and get instant results with energy efficiency information.

Frequently Asked Questions

Finn raske svar

What is the difference between watts and lumens?

Watts measure power consumption (energy used), while lumens measure light output (brightness). Lower wattage bulbs with higher lumens are more energy efficient.

Why do different bulb types have different conversion factors?

Different lighting technologies have varying efficiencies. LEDs produce more lumens per watt than incandescent bulbs, making them more energy efficient for the same brightness.

Are the conversion factors accurate for all brands?

Our tool uses industry average conversion factors. Actual values may vary slightly between manufacturers, but these provide a reliable estimate for comparison.

Can I use this tool for commercial lighting calculations?

Yes, this tool provides accurate estimates suitable for residential and commercial lighting planning, though professional lighting design may require more detailed calculations.
