New “Cold Cathode” Fluorescents: 85% Less Mercury

It’s a new fluorescent bulb that could have a bright future — the cold cathode fluorescent lamp (or CCFL). These bulbs contain half the mercury of conventional “hot cathode” fluorescents. They have a thinner tube diameter, which allows them to run cooler, and last up to four times as long (a lifespan of 25,000 hours). This means that the mercury is reduced by 85% over the life of a cold cathode bulb, because a regular CFL would have to be replaced three times during that period. Another big advantage of CCFLs is that they are fully dimmable, and “on/off” cycles do not shorten their life.
