How much area (in Dia) it will cover at a particular height?
- Magical number 0.018
- Formula –
- Diameter of Light = 0.018 x Beam Angle x Height
- Ex : Downlight with 36 Degree beam at 3 Meter Distance / Height
- Diameter = 0.018 x 36 x 3
- Total – 1.944 Meter (Area it will cover at 3 meter height)
Note – This formula works upto 50 Degree
