Cold Cathode Light Bulb

A cold cathode light is a tubular light that works by passing an electrical current through a gas or vapor, much like neon lighting. Cold cathode lights can come in many sizes and colors, and there are many advantages over neon and fluorescent lighting.

The first advantage is that cold cathode lights do not get hot. They are also used for decorative lighting and to modify the interior and sometimes the exterior of cars, most often the undercarriage.

A cold cathode light is up to five times brighter than neon lighting, and it has one of the longest lives of any lighting fixture at about 50,000 hours. Unlike incandescent bulbs, the longevity of one of these lights is not shortened by the repeated action of turning it off and on.

For architectural and design purposes, cold cathode lights are ideal. Cold cathode lights take as little as 7.5 watts of electricity per 1 foot (.3 meters) and are flicker-free. The instant power is supplied the cathode tube illuminates to its full brightness and remains so until the power is cut.

For all of its flexibility of design options, longevity, brightness, color and cool temperature, cold cathode light is finding its way into nearly every aspect of life.
