- Lumens to Watts Converter
This free online calculator will help you convert lumens to watts and vice versa. So you can calculate how many lumens the new LED lamps should have based on your previous lights. If you already have some LED lamps on your shortlist, you can convert their lumen value into the output (in watts) of previous lighting.
To make sure you get the same brightness from your energy efficient bulbs, use this chart to compare the wattages of different technologies.
Use this calculator to estimate the lumen output that will be created from your chosen wattage of light source. Enter the wattage, then either choose the most appropriate light source from the list or enter the lumens per watt of your light source, to get the light output in lumens.
Use our lumens to watts conversion chart to choose the right LED bulb every time.
23 Οκτ 2024 · Learn how to convert lumens to watts, choose the right LED bulbs, and maximize energy efficiency with our detailed guide and conversion charts.
Formula of converting watts to lumen. Фv (lm) = P (w) x η (lm / W), which means that the luminous flux in lumens is calculated by multiplying the power in watts by the luminous efficacy in lumens per watt. The watts to lumen calculator delivers accurate results based on the values entered in the text fields.
