CCFLs (Cold Cathode Fluorescent Lamps)
Basically tubes of light. They come in different colors like red, blue and green. You also have UV CCFLs. When the light from a UV CCFL hits a UV reactive product like a fan or a IDE cable, the fan or the cable glows.
UV Reactive Cables
IDE, SATA and floppy cables run through the motherboard and are very visible. UV reactive cables are made of UV reactive materials and glow when exposed to UV light in the form of UV CCFLs.
