Fluorescent tubes and compact fluorescent lamps (CFLs)![](http://www.ecoresource.ca/dat/services/26.jpg?ttt=1335466423)
use less electricity and last longer than conventional light bulbs,
but they also contain small amounts of mercury, a poisonous heavy
metal, which is used to produce their light.
Eco Resource Management can arrange for safe disposal of fluorescent bulbs and ballasts.![](http://www.ecoresource.ca/dat/services/25.jpg?ttt=1335466423)
