This tool converts watts to lux, helping you accurately measure light intensity.
How the Watt to Lux Calculator Works
This calculator converts watts to lux, taking into account the distance from the light source, light efficiency (lumens per watt), and the beam angle. Lux measures the illuminance, indicating how much luminous flux (lumens) spreads over a given area.
To use this calculator, follow these steps:
- Enter the electric power in watts of your light source.
- Enter the distance in meters from the light source to the point of measurement.
- Enter the light efficiency in lumens per watt. This value can usually be found in the specifications of your light source.
- Enter the beam angle of the light source in degrees.
- Click the “Calculate” button to get the results.
The calculator does the following calculations:
- Calculates the lumens by multiplying the watts by the light efficiency.
- Converts the beam angle from degrees to radians and uses it to find the area illuminated by the light.
- Calculates the lux by dividing the lumens by the illuminated area.
Limitations
This calculator assumes a uniform distribution of light within the beam angle and does not account for variations in light intensity or reflections. Actual results may vary due to these factors.
