Precaution Note: Compact fluorescent (CFL) bulb contains about 5 milligrams (mg) of mercury, a toxic heavy metal, bulbs should be recycled or proper disposal. Please ensure it does not end up in landfills.
I have one broken Compact fluorescent bulb at home, I does not know how to recycle it at this moment in Malaysia, so I wrap it with few layers of newspaper and keep it in the cupboard. Hopefully will found out the way to recycle or dispose this bulb safely :)
Currently, there is a new invention of energy saving bulb using the LED technology. LED bulbs are lit solely by the movement of electrons. Unlike incandescents, they have no filament that will burn out; and unlike CFLs, they contain no mercury or other toxic substances. Proponents say LEDs can last some 60 times longer than incandescents and 10 times longer than CFLs. Example of energy savings calculation of LED bulb: a 1.3-watt LED bulb, could generates as much light as a 15-watt incandescent bulb, saving about 13.3 watt of electricty.
