Lighting beam calculator
WebJun 2, 2024 · The beam calculator uses the following formula to calculate beam angle for a light bulb or a lamp: ∝ = 2 ( t a n ( − 1) θ 2 × d) Where, ∝ = Beam Angle θ = Diameter of the object or surface to be illuminated d = Distance between lamp and object or surface tan -1 = Inverse function of the tangent for angle calculation WebPictures & ArtworkCalculator. To use the Number of Lights and Placement Calculator, you’ll need to measure your rooms. If you have an open floor plan or an area without four walls, consider each area a separate room when measuring and calculating the lighting. Just imagine a wall wherever you would consider the edge of the room to be.
