CFL Bulbs, better known as compact fluorescent lamp or energy saving bulbs are actually very dangerous. They emit carcinogenic EMF( electo-magnetic field) radiation and contain a low pressure mercury-vapour gas which is also highly toxic.
These bulbs should have never been approved for use around people or animals due to their carcinogenic properties but we have our American Standards Association to thank for that.
I also have replaced all conventional or incandescent light bulbs due to their high energy consumption and high heat emission.
Incandescent bulbs do not emit EMF radiation but are dangerous due to hot surface and being a fire hazzard.
The replacement bulbs of my choice were 7 watt LED bulbs which give the same illumination and lumen output as a 60 watt incandescent but stay cooler and use 850% less current.
Light emitting diodes or LED lighting is the choice for most lighting applications today due to their longivity, which usually last 100,000 hours, as well as some of the reasons that I mentioned before.
