EBU GROUP on LED-based studio lights
  

Background

 

This Group addresses the use of High efficiency lighting, such as LED lights, in professional television and film production.

 

The challenge

 

The introduction of high efficiency LED lighting is leading towards a number of unintended and possibly expensive consequences for both television and film production.

 

Studies already undertaken show the lighting industry colour-rendering index is inappropriate for television because of the floating white point.

 

The aim of this group is to show how these studies could lead to the design of a “Standard camera” model, much along the lines of the human CIE “Standard observer” .
