K

Kelvin Unit of measurement for color temperature, expressed in degrees Kelvin (K).
  • 1900K-3000K Warm White (flames, light bulbs, sodium...)
  • 3000K-4500K White (dawn, dusk...)
  • 5600K-6500K Daylight (daylight, sun at its zenith)
  • 6500K-10,000K Overcast (overcast sky, bluish sky...)
Key Light

Key light, the main lighting source of the scene, directly illuminates the subject's face. *see three-point lighting.

 

L

Louver Lighting accessory that narrows the light beam. A grid or filter with regular interstices, attached to the front of the projector.
Lumen Unit of measurement for luminous flux expressed in lumens (lm). It is a photometric unit, just like the candela (cd) from which it is derived, based on human perception of light using the spectral luminous efficiency function (lm/W).
Lux

Unit of measurement for illuminance, denoted (lx). It characterizes the luminous intensity received per unit area, uniformly distributed, with a luminous flux of one lumen per square meter.

 

M

Mapping Displaying patterns, images or videos on LED panels.
Match To match an existing source (halogen light, screens...)
Minette Small, lightweight, and portable light source.

 

O

Octa Eight-sided softbox.

 

P

Protocol

DMX channel configuration modes to be defined according to scene requirements. For example, for the same DMX channels 1-2-3, protocol A: 1=Intensity 2=White 3=Amber; whereas protocol B: 1=Red; 2=Green; 3=Blue.
