Longus - LED Rail Spot - LIGHT CURVE

We provide brightness (IES) curves for each luminaire on our website.
The light curves graphically show how the light is spread to the field.
The light source is located at the center of the system (that is, at the pole of the graph).
When the armature assembly is symmetrical about the vertical axis (circle, square), we only construct a density distribution curve in a vertical plane.
My status is red. If the assembly of the lamp is not symmetrical, we add a blue curve to the graph.
The blue curve shows how the light source shines with 90 degrees of movement against the first position.
When measuring the armature in the welding axis, we measure the C90-C270 plane, while measuring the light axis perpendicularly measure the C0-C180 plane.

LONGUS – LED Rail Spotlights
  • The given brightness values are measured with a goniophotometer.
  • KARMA laboratory (in comparison with accredited institutions)
  • we measure our armatures by ourselves and record the output of the light.
  • So you can be sure that the armature is illuminated as shown.
