16 LED Filters
LED conversion Filters Because the white light emitted from an LED fixture has a strong blue cast, it appears cold when compared with a tungsten white light. In order to overcome this problem, LEE Filters has introduced the LED CTO Filter range (CTO stands for Colour Temperature Orange), which is designed to give the white light from an LED source a more tungsten-like warmth. In effect, the filters take the 5000K to 7000K colour temperature of an LED source and convert them to the appearance of a 3200K tungsten source. This allows lighting designers to mix the two sources without the viewer or camera picking up on any difference.
