Calculate Beam Angle fromLumen ~ Lux
This Excel Spreadsheet contains calculations for lumen output, illumination diameter, and lux levels at different distances from lighting fixtures with varying beam angles. It compares the illumination levels from five different fixtures with beam angles ranging from 10 to 120 degrees that all have a lumen output of 12345. Wider beam angles result in greater illumination diameters but lower lux levels at a given distance compared to more focused beam angles.
- Calculate Lighting Fixture Beam Angle
- Calculate Illumination at Surface from Beam Angle.
- Calculate Lighting Fixture Lumen from Beam Angle.
