CCFL (Cold Cathode Fluorescent Lamp) tubes are sealed glass tubes filled with inert gases that emit ultraviolet (UV) light when a high voltage is applied. This UV light excites a phosphor coating inside the tube, producing visible light. CCFLs have been used as white-light sources to backlight LCDs and are valued for their even lighting, brightness, and long life. In PC builds, they provide smooth, uniform illumination without the hot spots typical of LED strips, making them ideal for aesthetic lighting inside cases or reservoirs.

CCFL tubes provide even lighting along their length and strong UV output, which can be advantageous for certain aesthetic effects in PCs. However, LEDs are generally more energy-efficient, produce less heat, and have longer lifespans (often over 100,000 hours). LEDs also offer more vivid color options and are smaller and cheaper. CCFLs require high-voltage transformers that generate heat and electromagnetic interference, and they can dim after about a year, whereas LEDs maintain brightness much longer. Due to these factors, LEDs have largely replaced CCFLs in modern PC lighting.
