Do fluorescent lights give off radiation?
Since CFLs are designed to provide general illumination, the majority of the light emitted by CFLs is localized to the visible region of the spectrum (approximately 400-700 nm in wavelength). In addition, typical CFLs emit a small amount of UVB (280-315 nm), UVA (315-400 nm) and infrared (> 700 nm) radiation.
Are LED lights healthier than fluorescent?
We suggest using incandescent or halogen bulbs throughout the day + night if you're after a greater sense of well-being.

Why are fluorescent lights so popular?
It’s easy to see why: these lights are bright, energy-efficient, inexpensive and long -lasting – and they require very little maintenance and extremely infrequent bulb changes.
Can UV light cause headaches?
Exposure to UV light can cause dizziness, eye strain and migraines in some people, but it can do this only if you’re exposed to a large amount of radiation in a short amount of time. The Canadian study found that these bulbs don’t put off nearly that required amount of radiation and ultimately concluded that as long as the bulb is at least a foot away while using it, you won’t experience any harmful effects. As for those long tubes that light up your office, the simple cylindrical shape makes them even more effective at containing this radiation, which means you’re even less prone to exposure than you would be with a CFL bulb.
Do Fluorescent Lights Impact Your Sleep Pattern?
Some people have claimed that working under fluorescent lights for eight hours a day disrupts their circadian rhythm to the point where they can’t sleep properly .
Why do we need fluorescent light bulbs?
So using fluorescent lightbulbs that allow some UV radiation to escape would have the same effect as spending some time in natural sunlight, enhancing physical and mental health.

Fluorescent bulbs out-last incandescent bulbs, and you point out, are significantly more efficient. LED bulbs are even more efficient, safer, come in white, yellow, blue, and many other colors. Do not lick light bulbs. Dispose of light bulbs properly.
How much mercury does a broken CFL release?
A child exposed to a broken CFL bulb will receive eight thousand timesthe recommended amount of mercury vapor! A broken 13-watt CFL bulb will only have released 30% of its mercury a full four days after it is broken —the remainder is trapped in the bulb.
What are the chemicals in CFL bulbs?
German scientists foundthat several different chemicals and toxins were released when CFLs are turned on, including naphthalene (which has been linked to cancer in animals) and styrene (which has been declared “a likely human carcinogen”). A sort of electrical smog develops around these lamps, which could be dangerous.

They recorded concentrations near the bulb of up to 800 mcg/m3, which is eight times the average eight-hour occupational exposure limit allowed by OSHA (100 mcg/m3).
What happens when you expose skin cells to CFLs?
Healthy skin cells exposed to CFLs showed a decrease in their proliferation rate, an increase in the production of reactive oxygen species, and a decrease in ability to contract collagen.
What happens when a bulb is hit by an electric current?
Once that vapor is hit with an electric current, it emits a great number of UV rays. UV rays are theoretically absorbed by the layer of phosphor that coats the bulbs—but the signature twisted spiral shape makes these bulbs more prone to cracks in the phosphor, which dramatically increases UV/mercury exposure.

Outdoor sunlight can supply the maximum recommended daily UV exposure in 20 to 100 minutes.
Can CFLs emit UV light?
Not all open CFLs produce significant UV emissions. However, close proximity to bare skin can result in exposure levels similar to direct sunlight. The Health Protection Agency of the United Kingdom recommend that in situations requiring close proximity to the light source, open (single envelope) CFLs be replaced with encapsulated (double envelope) CFLs.
How do fluorescent lights work?
The best way to find the answer is to firstly understand how fluorescent lights work. Inside the bulb, electrical discharge excites a gas (usually neon or mercury vapour in argon), which emits ultraviolet radiation. But the ultraviolet radiation is not visible to human eyes and must be converted into visible light.

Safe distances. The emissions from all sources of light decrease rapidly with distance. At a typical use distance (more than 25cm), the UV light emitted from fluorescent lights falls below the level of general concern for healthy individuals.
How long does it take for UV light to penetrate skin?
The UV level absorbed by our skin after eight hours’ exposure to indoor lights, at a typical use distance (25cm), would be equivalent to just over a minute of midday solar exposure on a clear summer day in a city such as Sydney or Melbourne. This shows the risk to us is very small indeed.
How long is the exposure time for a light bulb?
At a measurement distance of 10cm, an exposure time of less than eight hours would be safe for almost all types of lights. Compare this to the permissible exposure limits (PELs) in typical midday summer sunshine, which is six minutes in Brisbane and seven minutes in Sydney and Melbourne.
Can UV light be converted to visible light?
But the ultraviolet radiation is not visible to human eyes and must be converted into visible light. This is done by the light’s interior fluorescent coating, which is able to absorb most of the UV radiation and emit lower-energy wavelengths in the visible spectrum. But some UV rays get through the bulb, especially if the bulb’s internal coating is ...
Is fluorescent light harmful to humans?
So, if a standard fluorescent tube lighting source is shielded by a standard acrylic plastic diffuser, there’s rarely a risk for human health, even for people who are affected by light sensitivity.
Can UV light pass through a light bulb?
But some UV rays get through the bulb, especially if the bulb’s internal coating is cracked, allowing more UV light to pass through. In fact many types of lighting used in our homes emit small amounts of UV radiation.
