LumiBOX en LumiString guidelines regarding brightness of light boxes / columns

We developed the LumiBOX LED strips for the illumination of two-sided light boxes and columns.

Both LumiString LED modules LED strips, and LumiBOX LED strips can be used for single-sided light boxes.

For outdoor signage applications we  distinguish three different brightness levels:

  • Low brightness: <75 cd/m2 or <200 lux
  • Average clarity: 75-150 cd/m2 or 200-400 lux
  • High Brightness: > 150 cd/m2 or> 400 lux
  • A light box with fluorescent tubes has an average of 750 cd/m2

Guidelines for the LumiBOX LED strips with illumination from the side:

  • 135 cd/m2 or 360 lux: a double-sided light box with 100x100x14cm with illumination from one side with 8 LEDs (80% energy savings compared to fluorescent tubes).

  • 55 cd/m2 or 150 lux: a double-sided column of 300x125x30cm with illumination from the two short sides with 2 x 6 LED (90% energy savings compared to fluorescent tubes).

Guidelines for LumiString LED module with direct illumination from the back plane:

  • 800 cd/m2 or 2150 lux: a single-sided light box with a depth of 10/14/20cm (40-50% energy savings compared to fluorescent tubes )
  • 400-500 cd/m2 or 1250 lux: a single-sided light box with a depth of 10/14/20cm (60-80% energy savings compared to fluorescent tubes).
