No. The risks are approximately equal. For some time it was hoped that UV lamps could be made safer by making more use of long-wavelength (UV-A) radiation. That type of radiation is much less carcinogenic than the shorter-wavelength UV-B radiation, but one needs more UV-A than UV-B for acquiring a tan.

The UV rays emitted by indoor tanning lamps do not emit sufficient energy to penetrate past the skin layers. Thus, despite claims and rumors to the contrary, internal organs are not directly impacted by longer wave UV light.

The amount of UV radiation that a person is exposed to depends on many factors including time of day, season and latitude. The spectrum of UV radiation from a tanning bed is similar to that of sunlight. It is less intense than being in the sun at the equator in June at noon, but more intense than being in the sun in Boston or San Francisco at the same time of year.

Natural sunlight is a good healer for many people with psoriasis, but there are some who do not respond and some who are made worse. Sunlight consists of several different types of light across a spectrum ranging from infra-red, through visible light, to ultraviolet (UV). It is the ultra-violet part that can help in treating psoriasis.

Yes. If you plan to tan in a UV bed and the Sunless Express Spray Spa on the same day, we recommend you tan in the UV bed first. Tanning in the UV bed after the Sunless Express Spray Spa may alter your results due to the heat and perspiration.

No. To date, no well-designed studies support the connection between melanoma and UV exposure from tanning beds. The relationship between melanoma and UV light exposure is complex. For example, melanoma is more common in people who work indoors than in those who work outdoors, and those who work both indoors and outdoors develop the fewest melanomas. Further, melanoma most commonly appears on parts of the body that do not receive regular exposure to UV light.

Since UV readings vary dependent upon meter brand, lamp brand, ballasts, voltage, age, and acrylic transmission, lamps need to be measured when new to determine what they should read in OEM equipment. Since it takes a "burn in" periods for tanning lamps to evenly distribute the gases and mercury, you may want to wait until you have 10 or more hours on the lamps before taking your first reading. Take readings from 2 or 3 different lamps in the same manner.

Lamp manufacturers generally strive to minimize ultraviolet light (UV) radiation in all lamps used in general lighting applications. The amount of UV produced by standard fluorescent lamps, such as those in your office, home, or school, is not hazardous and does not pose a major health concern. In fact, a paper by the National Electrical Manufacturers Association (NEMA) explores this subject in more detail.

CaluTech products use UV-C germicidal lamps which operate at a wavelength of 253.7 nanometers and can last as long as 3 years. Each lamp is under warranty for 1 year, and 36W replacements are only $22.99 each, not $40 or $80 each like other companies (we don't mark them up). Replacement 18W lamps are $22.49. It is a very cost effective UV air purifier. The lamps are known to operate for as long as 3 years. We recommend annual changes of the UV lamps for maximum ultraviolet air sterilization.

If you want to find tugtupite, especially the hard-to-spot-in-daylight tugtupite, these LW LED sources -- even the good ones that work really well -- can be your worst enemy. Here's why: tugtupite has a set of emission lines in the yellow-orange that's best stimulated by UV in the 350-400 nm range; i.e. the excitation peak for the orange response lies squarely in the LW.

Many UV lamps intentionally produce ozone in large amounts (UV-V), which we do not recommend, nor does the EPA or American Lung Association. The UV lamps we use (UV-C) have special tubing that filters out the 185nm ozone wavelength, however all UV lamps that are considered 'ozone free' do produce some ozone, but the amount of ozone produced is so minute it is not considered an ozone producing lamp.

Indoor tanning is a controlled environment, which allows you to slowly build a gradual tan, to develop pigmentation and increase your natural SPF - thus providing a controlled environment. The external factors of tanning in the sun, such as time of year and day, altitude, cloud coverage, pollutants, reflective surfaces, etc. are harder to control or predict - which increases your risk of overexposure.

Several safety measures protect service technicians and homeowners from eye or skin UV exposure, including a lamp shutoff switch, and a sight glass for safe and easy lamp inspection. A protective cover with a safety interlock switch immediately deactivates the lamp before the service technician or homeowner can access or service the unit. The effectiveness of germicidal UV-C is limited once molds, which are more resistant to UV energy than airborne bacteria, have already formed on surfaces.

CAP UV-C and UV Plus products are equipped with high quality, high-output U.S.-made lamps for optimum performance and reliability. The hard quartz lamps are rated for at least 9,000 hours (1 year) when installed and used in accordance with the operating manual. Lamps may last much longer in some situations, but annual lamp replacement is recommended since the UV output of any lamp typically starts to drop off after about 9,000 hours. On/off lamp cycling will reduce lamp life.

Indoor tanning parlors should be avoided, since they expose people to the same kinds of ultraviolet radiation as sunlight. Most tanning devices give off as much as 10 times more ultraviolet A (UVA) radiation than is received from the sun. UVA radiation in high doses, whether from tanning devices or sun exposure, may increase the risks of skin cancer and premature skin aging.
