Use this calculator to determine either the size of the circle of light how far away you should place the light or which degree of lens you should use.
Led light beam angle calculator.
For example a beam angle on 30 degrees means the light has a shape of a cone and its borders form a 15 degree angle with the center axis.
If you already know which lights you want to install you can enter their size and beam angle to get the approximate number of lights needed.
Handy tool to calculate the size of the light beam coverage.
This can be determined very well with the beam angle calculator.
For example a 1 candela light source will product 1 lumen per square meter at the distance of 1 meter.

The beam angle of a lamp is the angle at which the light is distributed or emitted.
Lamps such as halogens and some leds come in a variety of angles from 4 degree to 60 degree with some of the larger halogen lamps up to 120 degree.
Use our lux lumens calculator to determine how much light is needed for your industrial lighting application.
The ideal beam angle usually depends very individually on the place of use of the lamp and on your own use case.
The beam angle of an led spot determines the diameter of the generated light circle on the illuminated surface or object.
Beam angle calculator december 11 2007 by rob sayer on stage lighting presents a simple beam angle calculator to help you find the correct spotlight for your show.
The beam angle is the angle of radiation for a light source.
Use the number of lights calculator to get an approximate number of recessed lights a room needs for general lighting.
If you need to project a gobo image to a certain size or the pool of a spotlight to be a specific width you need to find out the beam angle.
Enter the size of your led chip or select from one of the defaults we have entered and the desired lens size to calculate the achievable beam angle.
Most leds produce a lambertian beam.
Please note that the estimate works for leds with a lambertian beam angular profile.
Figure out the led lens beam angle needed.
Just enter two known values and click the calculate button to calculate the unknown value you are looking for.
Distance from surface to light.
How to use it.
Enter lens beam angle distance from wall and height.
This calculator provides a rough estimate based on a etendue calculation.
Values can be in feet or meters but both values must match.
Then you can use the placement calculator on the next page to get an idea of where to place them.
