Spot Light Beam Angle
A wider beam.
Spot light beam angle. For instance if you wish to know the coverage area spot size of a 10 beam mounted 25. Narrow beam angles from a very narrow 15 degree spot to a wider 60 degree flood make the light more intensive and intense. Just enter two known values and click the calculate button to calculate the unknown value you are looking for. The beam angle that the manufacturers provide as a degree does not help most people.
The below calculator will help you to figure spot size. Most led lights are available at selected beam angles. Most led lights are available in a choice of beam angles. What you want to know is the area that a flood light will illuminate.
The spot size of a flood light bulb is the diameter at any given distance that the bulb illuminates to 50 of the maximum light output. The beam angle of a lamp is the angle at which the light is distributed or emitted. This convenient calculator will determine the beam angle the beam spot size or the distance of a beam. For this reason the illuminated surface appears larger but also much darker.
A wider beam angle will distribute the light better to more areas of the room. Knowing how to use beam angles correctly can vastly improve the lighting. How to use it. The spotlight with a beam angle of 60 must illuminate a much larger area with the same light output as the 15 spotlight.
A narrow beam angle makes the light more focused and intense.
