Check out the details that explain what you can do from this data.


Longus - LED Track Spot

We provide luminance (IES) curves for each luminaire on our website.
The light curve graphically shows how the light diffuses into the space.
The light source is located at the center of the system (ie in the polar area of the graph).
When the fixture assembly is symmetrical about the vertical axis (such as circle-round, square), we create only one density distribution curve in a vertical plane.
So the red color appears, when the Armature assembly is not symmetrical, we add a blue curve to the graph.
The blue curve shows how the light source shines with a 90 degree movement against the initial position.
When measuring the luminaire inside the source axis, we measure the plane C90-C270; when measuring the light axis vertically, we measure the plane C0-C180.

LONGUS – LED Track Spot
  • The given brightness values are measured by Goniophotometer.
  • In the KARMA laboratory (compared to accredited organizations)
  • we measure our luminaires ourselves and record the luminaire output (.IES/.LDT).
  • So you can be sure that the luminaire illuminates as shown.
