What to know about mercury in light bulbs?
Mercury is essential to a fluorescent bulb's ability to emit light; no other element has proved as efficient. As effective as it is at enabling white light, however, mercury—sometimes called quicksilver—is also highly toxic. It is especially harmful to the brains of both fetuses and children.
What do light bulbs contain mercury?
Do light bulbs contain mercury? A bulb can be an efficient light source if it has mercury in it. The mercury is sealed inside the glass tubing. The mercury in older thermometers is equal to the mercury in over 100 small fluorescent light bulbs. See also Battery Operated outdoor Lights with Timer.
Can mercury in light bulbs hurt you?
Fluorescent bulbs contain mostly mercury vapor, but can contain small amounts of liquid mercury. The nervous system and kidneys are sensitive to mercury exposures. Mercury can also harm unborn children. Health effects of mercury depend upon exposure route, duration and level of exposure.
Which light bulbs contain mercury?

Do light bulbs give off mercury?
Light bulbs. Traditional tungsten or filament light bulbs don't contain mercury. These bulbs are being phased out and replaced with energy-saving light bulbs. Some energy-saving light bulbs contain a tiny amount of mercury, sealed inside the bulb.
What if I break a CFL bulb?
Is it harmful to be in the room where a CFL bulb has broken? The amount of mercury vapor that is released from one broken CFL bulb is not enough to make anyone sick. However, to avoid any exposure to mercury, we recommend that you leave the room for at least 15 minutes before cleaning up the broken bulb.
What happens if you break an LED light bulb?
Although they contain hazardous materials, such as lead and nickel, LEDs are considered safe because the concentration of these substances is so minimal. Beyond the obvious dangers of shattered glass, broken LEDs have no dangerous implications and can easily be disposed of.
What happens if you breathe in mercury vapor?
If inhaled, mercury vapors can be highly toxic. What immediate health effects can result from elemental mercury exposure? Inhaling high concentrations of mercury vapor can cause a cough, chills, fever, and shortness of breath, and sometimes nausea, vomiting, and diarrhea.
How much mercury is toxic to humans?
For elemental mercury vapour, several studies show that long-term workplace exposures– at around 20 µg/m3 of air or higher – have subtle toxic effects on the central nervous system.

Do LED light bulbs contain mercury?
LEDs use significantly less energy than even CFLs, and do not contain mercury.
What are the safest light bulbs to use?
One of the most efficient and long-lasting types of bulbs on the market, LED bulbs pose no fire hazard thanks to their ability to absorb the heat that they create. LEDs have been found to contain a number of harmful chemicals and substances including arsenic, lead, and nickel.
Do UV light bulbs contain mercury?
Overview. Although UV disinfection is generally considered safer than chemical disinfection, all conventional UV lamps typically use between 5-200 mg of mercury per lamp.
Do all fluorescent bulbs have mercury?

Is mercury in light bulbs toxic?
Since the type of mercury (elemental mercury) in mercury-containing light bulbs is toxic, consumers should handle certain light bulbs with care.
What is mercury vapor lamp?
Mercury vapor lamps are bright, long-lasting light sources that are often used to light large areas such as streets, gyms, sports arenas, banks, or stores . The bulbs have an inner quartz tube containing the mercury vapor discharge. This is enclosed by an outer glass bulb that filters out harmful short-wavelength ultraviolet (UV) radiation.
How long does it take for a mercury vapor light bulb to shut off?
“T” type light bulbs have a self-extinguishing feature that shuts off the light within 15 minutes after the outer bulb is broken. “R” type light bulbs do not have a self-extinguishing feature.
Can mercury vapor lamps cause eye burns?
Under normal operating conditions mercury vapor lamps provide efficient, long-lasting sources of light. However, if the outer bulb breaks, and the inner tube continues to produce unshielded light, intense UV radiation is emitted. UV exposure at this level can cause eye and skin burns, blurred or double vision, headaches, and nausea.
Can mercury vapor light bulbs cause burns?
Ultraviolet radiation burns from high intensity mercury vapor light bulbs are a public health concern, especially in schools and other indoor facilities where the light bulbs may be subject to damage. The best way to reduce the risk of burns is to use fully-enclosed fixtures or self-extinguishing “T” type mercury vapor light bulbs in facilities where the public can be exposed to the UV radiation from a broken bulb.
How to dispose of mercury?
Vacate the room and ventilate it for at least 15 minutes. Do not use a vacuum cleaner, but clean up using rubber gloves and aim to avoid creating and inhaling airborne dust. Sweep up all particles and glass fragments and place in a plastic bag. Wipe the area with a damp cloth, then add that to the bag and seal it. Mercury is hazardous waste and the bag should not be disposed of in the bin. All local councils have an obligation to make arrangements for the disposal of hazardous household waste.
How much mercury is in a CFL?
How much mercury do CFLs contain? Up to 5 milligrams - a tiny amount when compared to the 3 grams in a mercury thermometer, says Adrian Westwood, from the UK Environment Agency. Fluorescent strip lights contain similarly tiny amounts, reduced from the 100 milligrams present in first-generation CFL bulbs.
How to clean a broken light bulb?
Their advice for cleaning up a broken bulb: Vacate the room and ventilate it for at least 15 minutes. Do not use a vacuum cleaner, but clean up using rubber gloves and aim to avoid creating and inhaling airborne dust. Sweep up all particles and glass fragments and place in a plastic bag.
What happens when a light bulb is switched on?
When the bulb is switched on, electrons stream from a tungsten-coated coil. They collide with mercury atoms, exciting their electrons and creating flashes of ultraviolet light. A phosphor coating (typically composed of metal oxides or phosphates) on the inside of the tube absorbs this light and re-emits it at visible wavelengths.
Is mercury released from CFL bulbs?
The amount of mercury released while powering and disposing of CFL bulbs is much smaller than is emitted for old-fashioned filament bulbs.
Is tungsten light bulb going to be phased out?
Old-fashioned tungsten light bulbs are due to be phased out in Australia, the UK, and the US over the next five years, and the spotlight has fallen on their low-energy replacements. The new light bulbs contain mercury, which has triggered a rash of concerned media stories - but is there any fact behind the fear?
Is mercury in fluorescent bulbs?
The presence of mercury in fluorescent lights, though well known, seems not to have been well communicated to the public in the UK. But as Steve Poole, laboratory manager for the UK trade body The Lighting Association, points out, ’fluorescent technology has been around for years without this being worthy of comment before.’ Now that CFLs are seeing widespread use in households, the mercury issue has been rediscovered, leading to calls for advice on light bulb disposal to be printed on CFL packaging. The disposal advice itself has not changed.
How much mercury is in a fluorescent light bulb?

When did the state of New Jersey require mercury information?
In 2002, the state of New Jersey requested mercury dose information for lamps purchased through the state contract, which included many different types of lamps. See the New Jersey fact sheet at https://informinc.org/fact-sheet-mercury-disclosure-requirements-new-jersey-lamp-contract (or access PDF version) for that information.
Does an Alto lamp burn out faster than a TCLP lamp?
INFORM received some anecdotal claims that TCLP-compliant lamps, and particularly the Philips Alto, burn out faster than non-TCLP-compliant lamps. However, INFORM is aware of no records that substantiate these claims. All lamps are rated for average lamp life and should be replaced by the manufacturer if they do not meet the performance claims. Also, to function at their rated capacity, lamps must be used with compatible ballasts. Ask your vendors to help identify the lowest-mercury lamps compatible with your existing ballasts.
Can mercury be leached from a TCLP?
There is no evidence that the chemicals or mechanisms used to prevent mercury from leaching in the TCLP would prevent mercury from volatilizing if the lamp were accidentally broken, exposing nearby workers. The best way to reduce risk is to buy lamps with the least amount of mercury and to implement handling and storage methods that minimize the risk of breakage.
