I did an in depth speech and Q&A on the CFLs a few months ago to a few people at my school that wanted to become "greener"
My team and I could come up with NO reason they could pose a health threat except for 1 way and it doesn't compare to the dangers of allowing coal planets to produce 20% more Waste to power the old incandescent bulbs
CFL bulbs contain mercury and it is dangerous to life in the environment, especially in water... like fish and frogs (salmon naturally have fair amount of mercury)
BUT coal burning plants produce much much more mercury like 3000 time more than a CFL can in its lifetime, and the coal plants release the mercury in the AIR.
The only way a CFL can release mercury is if you drop it and crack it.
At home it will go into your carpet/wood floor.
its released in a powder form, so clean it up with a wet paper towel and gloves. Just be more careful next time
don't use a vacuum. it will only kick it into the air and into your lungs.
In the trash it WILL end up in the landfill and seep into the dirt > water
If you use CFLs you can drop your electrical usage by something like 40% ----- if everyone did that then we could reduce mercury productions coal plants by 20% (we use other things like fridges and ac units that still use the majority of electricity in the home)
point being --------- CFLs ultimately reduce mercury levels
AS LONG AS YOU RECYCLE THEM....
Almost EVERY place that sells CFLs offers a FREE recycling plan for you.
Just bring them back when they go out.....
DO NOT THROW THEM AWAY......
I think I recall CFLs have about .03 mg of mercury....... its not alot at all and quit harmless even if you swallowed that much.
BUT if you put together 10,000 of them in a landfill...... then well, what do you think will happen?
********************************************************************
OH, people don't like the cheaper/older ones. They tend to take a few second to turn on and the light just isn't quite....... comfortable?.... more like a blue grey light instead of a warm yellow.
some claim it causes Seasonal Affective Disorder, but in actuality, CFLs are used to treat it.
I replaced ALL my bulbs (15) with CFLs.......
I went from about 900w to about 120w and saved about 20 dollars on my monthly electric bill.
that savings payed of my bulbs in about 1.5 months and now I'm just saving approx 20 a month.
and they last 10 times longer.
Go Go Go getchya some
oh and the old incandescent bulbs are going to become illegal to produce and sell soon due to their HUGE power waste and consumption.

Well, the tubes in use contain mercury which is toxic over the long term. However, the mercury only gets out if the tubes are broken.
They cost more to produce, but use a LOT less energy and generate less waste heat than a standard incandescent bulb.
The flickering they can sometimes do, however, can cause headaches, eye strain, etc. related to the frequency of the pulses of light (incandescent bulbs generate light by exciting a filament, but fluorescent bulbs to it by passing a stream of ions down the tube, exciting the gas in the tube to eliminate electrons, which cause the coating on the inside of the tubes to give off photons.)
I'd use them - I do at home - replaced every standard bulb with compact fluorescent bulbs.

attempt employing Halogen or get your compact fluorescent at IKEA they have a lots greater valuable decision which incorporate some that produce gentle that seems and feels greater like incandescents. i exploit a mix of lights fixtures and for analyzing I actually have a gold lined color to develop the gentle ability and furnish a relaxing glow. Coloring your lampshade can do a international of sturdy.

My dad changed every single light bulb in our house to those energy saving bulbs, I guess they have mercury in them but I heard it wasn't dangerous. I personally don't like them but I don't pay the bill so whatever. I don't know if this is the same thing as what u r asking though.

Likely for the same reasons you shouldn't pick up the broken glass. The gasses used in the lights can be toxic. ...but think about the energy savings. Is the coal being used to burn a regular light not toxic as well?

There are all kinds of crackpots out there trying to sell books.
Flourescent bulbs contain small amounts of mercury. They pose no danger to the environment as long as they are properly recycled. No different than your rechargeable batteries.
