Information

This visualizer is design to show you what is possible with a fixture at a specific beam angle. The information used was gathered from manufactures' data sheets. If you find any inaccuracies, please use the contact link at the bottom of the page.

Red Line

The red line will let you find information at any position within the beam.

Beam Spread is the vertical (Y) measurement between the top and bottom red lines. If the bottom line is not present, then the bottom position is assumed to be 0.

Distance to Center is the length between the Instrument X and Y values and the spot where the red lines converge (Center Y and Red Line X).

The footcandle or Lux measurement is determined by the Center Y and Red Line X position.

Floor

This table will display data that applies to the floor or Y value 0.

Beam Spread is the distance between the outside blue markers. These markers show the spot where the field angles cross Y 0. If the left marker is past X 0, then it is assumed that the value is 0. The measurement will continue displaying the distance between the right marker and X 0.

Distance to Center is the length between the Instrument X and Y values and the spot where the center of the beam crosses Y 0 (Center X and Y 0).

The footcandle or Lux measurement is determined by the Center X and Y 0 position.

Back Wall

This box is exactly the same as the floor, except on the Y place with X being 0.

Units

The active unit of measurement is determined by the X. If the X is next to feet, then the unit of measurement is imperial.

Fixture Library

The library contains information from various manufactures. This information was collected from specification sheets and user manuals.

Select a manufacturer to display a list of all instruments associated with that manufacturer. These lists are not meant to be complete catalogs, please consult the manufacturer’s website for more information regarding their products.

The lamp data list is used to calculate the footcandles or Lux. If you do not select a lamp, then the footcandles or Lux values will be 0.

Custom Data

At the very least, enter a minimum beam angle. Setting a maximum beam angle will allow you to scroll through the degrees between the minimum and maximum values.

Enter candela to determine footcandles or Lux.

Press submit or hit the enter key to apply the custom data. This data will override any previous data in the visualizer. To determine want is currently active, look at the title above the grid.
