Values can be in feet or meters but both values must match.

Use our lux lumens calculator to determine how much light is needed for your industrial lighting application.
Please note that the estimate works for leds with a lambertian beam angular profile.
This convenient calculator will determine the beam angle the beam spot size or the distance of a beam.
This can be determined very well with the beam angle calculator.
The beam angle of a lamp is the angle at which the light is distributed or emitted.
Use the number of lights calculator to get an approximate number of recessed lights a room needs for general lighting.
Just enter two known values and click the calculate button to calculate the unknown value you are looking for.
Figure out the led lens beam angle needed.
Enter lens beam angle distance from wall and height.
This calculator provides a rough estimate based on a etendue calculation.
Handy tool to calculate the size of the light beam coverage.
The beam angle of an led spot determines the diameter of the generated light circle on the illuminated surface or object.
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.
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.
For example a 1 candela light source will product 1 lumen per square meter at the distance of 1 meter.
The ideal beam angle usually depends very individually on the place of use of the lamp and on your own use case.
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.
Most leds produce a lambertian beam.
Distance from surface to light.
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.
Put in two of the values and then hit calculate to find the third value.
Then you can use the placement calculator on the next page to get an idea of where to place them.
The beam angle is the angle of radiation for a light source.
The amount of lux in an area or on a surface can vary depending upon the distance the light travels and the angle at which it is dispersed.
