CF light bulbs, a dangerous bulbs for women and children

If broken indoors, compact fluorescent (CF) light bulbs release 20 times the maximum acceptable mercury concentration into the air, according to a study conducted by researchers from the Fraunhofer Wilhelm Klauditz Institute for German's Federal Environment Agency.

CF bulbs use only 20 percent as much energy as traditional incandescent bulbs and have become highly popular among consumers seeking to reduce both their energy bills and their climate footprints. The European Union has already begun to implement a phase out of incandescent bulbs.

Unlike incandescent bulbs, halogen bulbs or LED bulbs, however, CF bulbs are made with mercury, a potent neurotoxin that is especially dangerous to children and pregnant women. For the new study, the researchers tested a worst case scenario for two different CF bulbs that lacked a protective casing. Both bulbs were broken indoors when hot. One bulb contained 2 milligrams of mercury, while the other contained 5 milligrams.

When broken, the bulbs released roughly 7 micrograms of mercury into the air, 20 times the British government's recommended maximum exposure of 0.35 micrograms. Mercury levels remained elevated at floor levels for up to five hours after breakage.

There is no safe level of exposure to mercury.

"The presence of mercury is the downside to energy-saving lamps," said Federal Environment Agency president Jochen Flasbarth. "We need a lamp technology that can prevent mercury pollution soon. 'The positive and necessary energy savings of up to 80 per cent as compared with light bulbs must go hand in hand with a safe product that poses no risks to health."

If a CF bulb breaks, the U.S. Environmental Protection Agency recommends that you shut off all central air or heating and then ventilate and evacuate the room for 10 minutes. The bulb should then be cleaned up, such as with a damp cloth, and placed into a sealable container. The debris should be placed outside until it can be taken to a hazardous waste disposal facility.

All CF bulbs should be disposed of as hazardous waste, never in household trash.

Can I just replace the bulb & not the entire lamp housing? LMP H180 replacement lamp VPL-HS20?

I have Sony Home Theatre projector.
Can I replace just the bulb & not the entire housing? If so what other bulbs/lamps are compatible?

I've experimented with Mitsubishi and Sony lamps by going to a good lamp manufacurer like Ushio for the raw lamp. It's not recommended by the TV companies and it's not much of a savings. The cage is cheap, it's the lamp that's expensive.

I've had no trouble, but you should know there are several critical specs to the lamp, and the rest of the light engine is designed around those specs. For example, the color temperature of a TV lamp should be about 6400 kelvin, but not exactly. Arguably, 6504 is perfect.

If you don't understand this stuff, buy the complete unit and pay the extra 20 or so bucks. And I'd recommend doing it before the original lamp burns out. It's nice to have a spare laying around on Superbowl Sunday... Just in case!
