The amount of mercury in a fluorescent lamp varies from 3 to 46 mg, depending on lamp size and age. Newer lamps contain less mercury and the 3–4 mg versions are sold as low-mercury types. A typical 2006-era 4 ft (122 cm) T-12 fluorescent lamp (i.e. F34T12) contains about 5 milligrams of mercury.
How to Dispose of Fluorescent Tubes Safely
- Source.
- These tubes are considered universal waste and can be dropped off at a universal waste handler in large or small quantities.
- Head to your local Batteries Plus Bulbs store.
- You can also call 800-CLEAN-UP for help finding an appropriate disposal center near you.
EPA does not have a separate policy regarding the disposal or recycling of "green tip" lamps. Although these bulbs are not listed hazardous wastes, they are still hazardous waste if they exhibit a characteristic. The green tip fluorescent bulbs typically contain mercury in lower quantities than other fluorescent bulbs.
Managing and Recycling CFLs
Luckily, under the Environmental Protection Agency's (EPA) Universal Waste Rule, many mercury-containing light bulbs can be treated as non-hazardous waste, if properly recycled. The EPA-recommended method for the safe disposal of all types of fluorescent light bulbs is actually recycling.How to Dispose of Fluorescent Tubes Safely

Cleanup Steps for Hard Surfaces
- Carefully scoop up glass fragments and powder using stiff paper or cardboard and place debris and paper/cardboard in a glass jar with a metal lid.
- Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder.
Although mercury is a toxic pollutant, mercury exposures from broken CFLs are not likely to harm you and your family. More importantly for health, you can also be exposed to mercury through the air, as elemental mercury vaporizes readily (essentially becomes a gas) and can thus be inhaled into your lungs.
LED lights use the blue part of the spectrum to give out light. Which by the way is how the circadian rhythm in our bodies are regulated by. So they affect the hormones and some forms of cancer such as breast cancer and prostate cancer are hormone related. Research indicates that LED lights do cause cancer.
The Bad: Fluorescent tubes & CFL bulbs contain a small amount of mercury gas (about 4 mg) – which is toxic to our nervous system, lungs and kidneys. So long as bulbs stay intact, the mercury gas is no threat. This means bulbs should be handled properly to avoid breakage.
Traditional incandescent bulbs are fine, but many people are looking for a more energy efficient option. Luckily, “warm light” CFLs (Compact Fluorescent Lights) are okay for your eyes, as well as being much more efficient. They do emit UV rays, but a much smaller amount. You can also use LED bulbs or halogens.
Fluorescent tubes are a form of arc tube. The filaments in the ends heat up the gas and mercury in the tube to get it close to ionizing. If one of the filaments is not working the normal background may not be quite enough. Touching the bulb will introduce a new potential source providing enough kick to get it started.
* If you already vacuumed a broken CFL: For a recent break (within a couple of days of the break): Air out the house for up to several hours to get rid of any remaining mercury vapor and change your vacuum cleaner bag or wipe out the dust cup.
In short, the exposure from breaking a compact fluorescent bulb is in about the same range as the exposure from eating a can or two of tuna fish. The tiny amount of mercury you're exposed to when breaking a CFL is extremely unlikely to cause any ill effects, noticeable or otherwise.
Compact fluorescent lamps and risk of skin cancer. RESULTS: On average, the UV radiation from CFLs and subsequent carcinogenic exposure is lower than that from incandescent bulbs. However, defective bulbs can emit higher levels of UV radiation, which may cause significant damage.
The curlicue compact fluorescent lamps (CFLs) oft touted as an Earth-friendly alternative to standard incandescent bulbs may cause skin damage, according to a new study by researchers at Stony Brook University. Now researchers have found that ultraviolet radiation seeping through CFLs may damage skin cells.
Compact fluorescents, like their tubular fluorescent precursors, contain a small amount of mercury—typically around five milligrams. Mercury is essential to a fluorescent bulb's ability to emit light; no other element has proved as efficient. The problem comes when a bulb breaks.
Fluorescent lamps, including compact fluorescent lights (CFLs), use about 75 percent less energy than incandescent bulbs and last six to 15 times as long, according to the U.S. Department of Energy (DOE). But it's widely believed that these popular bulbs use a lot of energy to start up. Otherwise, turn the light off.
LED blue light exposure
But they also tend to produce more blue light. The physics of fluorescent lights can't be changed, but coatings inside the bulbs can be so they produce a warmer, less blue light.Fluorescent lights are ideal for plants with low to medium light requirements, like African violets. They are also good for starting vegetables indoors. In addition to this, fluorescent bulbs use 75 percent less energy than incandescent lights.
