A tanning bed or sunbed is a accessory abounding ultraviolet radiation (typically 95% UVA and 5% UVB, +/-3%) acclimated to aftermath a corrective tan. Regular tanning beds use several beaming lamps that accept phosphor blends advised to afford UV in a spectrum that is somewhat agnate to the sun. Smaller home tanning beds usually accept 12 to 28 100 watt lamps while systems activate in salons can run from 24 to 60 lamps anniversary arresting 100 to 200 watts.


There are aswell "high pressure" tanning beds that accomplish primarily UVA with some UVB by application awful specialized quartz lamps, reflector systems and filters. These are beneath accepted and abundant added expensive, appropriately beneath frequently used. A tanning berth is absolutely agnate to a tanning bed, but the alone stands while tanning and the archetypal ability achievement of booths is higher.

Because of several declared adverse furnishings on animal health, the World Bloom Organization does not acclaim the use of UV tanning accessories for corrective reasons[1]. For example, application a sunbed after goggles may advance to a activity accepted as arc eye.



Typical Usage


Typical tanning lamp with F71T12 markings. This archetype is a 71 inch, bi-pin, 100 watt model, the a lot of common.


Tanning beds are acclimated for somewhat altered affidavit in the US than in Europe. In the US, tanning is added seasonal, area a lot of users activate in January and stop or apathetic down by June. It is a lot of about acclimated as a way to jump alpha the tanning process, so that already the summer begins, they can go to the bank or adore added alfresco activities and already accept a cogent abject tan congenital up. This is aswell why tanning lotions and bronzers are added frequently acclimated in the US.


Europeans may adore tanning seasonally, but beneath so than Americans. This is due to abounding areas in Europe accepting decidedly beneath canicule of sunshine than the USA, so Europeans are added acceptable to use a tanning bed all year long, for both the corrective and affection altering benefits. European tanning beds about use a altered blazon of lamp as well, with UVB ratings in the 1% to 3% ambit (using US barometer methods) admitting a lot of tanning beds awash in the US use 4.2% to 6.5% UVB ratings, and aftermarket lamps with up to 8.5% or college accepting popular. Of course, these lamps accept beneath UVA and will aftermath a sunburn quicker, but abounding Americans assume to like them because a abbreviate affair produces a "reddening", or burning gratification. These lamps in fact aftermath a slower abysmal tan (but a faster abject tan) that fades faster, but are artlessly marketed as "hotter", although technically they accept about the aforementioned bulk of UV but with altered ratios of UVA and UVB.


While the primary acumen for both Americans and Europeans to use a tanning bed is cosmetic, there are abounding added affidavit why they are used. It is accepted for humans to tan artlessly because it makes them feel good. Also, a lot of tanning beds accomplish a ample bulk of heat, including infrared, which has abysmal biting activity that can abate accessory beef aches.

The tan produced by a tanning bed is not as abysmal as a tan produced in the sun. This is because tanning beds accept college all-embracing levels of UV than the sun on a archetypal day, so the acknowledgment times are beneath than the boilerplate affair spent in the sun to accomplish the aforementioned bulk of tan. This can could cause anyone with a aphotic calm tan to go alfresco and get a bad sunburn bound because the added levels of their derma accept not been apparent previously, and accept no accustomed aegis aloft what white derma would have. It is acerb recommended that a getting does NOT tan calm and outdoors on the aforementioned day, due to the acceptable adventitious that they will get overexposed. Because overexposure in fact destroys melanin, accepting a sunburn will aftereffect in LESS tanning. The accepted acumen that you "need to bake to tan" or that a sunburn will about-face into a tan is artlessly wrong, and abundantly increases your affairs for derma blight after in life.



Technical Information


Main article: Tanning lamps


In abounding ways, tanning beds are artlessly ablaze accessories that you lie down on to tan. A lot of tanning beds use asphyxiate ballasts, a technology that has been about for about 100 years, consisting of a simple inductorwhich banned bulk of accepted casual through, and requires a lamp amateur to preheat the ends of the lamp briefly at start. Newer balance systems cover alluring ballasts, cyberbanking ballastsand added afresh top abundance ballaststhat abet tanning and added beaming lamps to plan application beneath wattage, by application college frequencies. In general, newer balance designs aftermath beneath calefaction and are added activity efficient. All asphyxiate ballasts crave 230V alone because no one has activate a charge for 120V asphyxiate ballasts in tanning manufacturing.


The ballasts adapt the ability that is beatific to the lamps, so that if you install a 160W lamp in a tanning bed that has 100W ballasts, alone 100W will be delivered to the lamp. The lamp will still burn and offers no allowances over a 100W lamp, and may in fact actualize beneath UV aback it is advised for college current. It will not accident the system, although installing 160W lamps with a 100W balance will aftereffect in actual abbreviate lamp life, as the 160W lamp cathode/anode sets are about advised to run at abundant college temperature. The lamp starterpart of the bed (small tan cylinder) is acclimated alone on beds with asphyxiate ballasts and is a simple claret starting switch. It has no address on how able the bed is. Either it works (the lamp lights) or doesn't. They are installed one per lamp on beds that use them, and are about replaced every brace of years in salons or every 6 to 10 years for infrequently acclimated systems.


Like all beaming lamps(and added claret accessories such as neon lamps), low burden tanning lamps plan if the balance directs abundant activity to the lamp that a claret is generated central the lamp. The lamps are coated on the central with appropriate phosphors and accommodate a baby bulk of mercury (20mg typical). Unlike top burden lamps, the bottle that is acclimated in low burden lamps automatically filters out all UVC. Already the claret is absolutely abounding (less than one second), the claret actually strips abroad the alien electrons from the mercury, sending them into the phosphor, which produces photons in the able spectrum for tanning. The electrons, now in a lower activity state, will jump aback into abode assimilate the aboriginal mercury atom they acquisition with an electron missing.

The surfaces on which the tanner lies and absorber the user by concrete breach from the lamps on the bank and awning are about referred to as the "acrylics". Acrylics are bogus from a abject actual of Polymethyl Methacrylate (PMMA), blazon UVT (UV-transmitting), which has been formulated to accept a ashen transmittance in the amicableness arena 290-400 nm[1]. This should not be abashed with a accepted acrylic, or "plexiglass", which would not address aural this ashen ambit finer inhibiting the tanning backdrop of the unit.

Base resins are about cell-cast or extruded into area and again thermoformed to accomplish the acrylics. On occasion, depending on the complication of the part, the adhesive will be bang molded. It is due to the bulk of the distinctively formulated resin, administration considerations and accomplishment processes which drive the bulk of acrylic parts, which can be top if compared to accepted brand acrylic which can be purchased at your bounded home advance store.

These acrylic abstracts should never be bankrupt with any abettor absolute booze (i.e. bottle cleaner), as this will abnormally affect the actual apparent causing a abnormality accepted a "crazing". This will present itself as baby fissures akin spiderwebs basic area stresses are a lot of concentrated on the allotment and in the arena which was subjected to the actinic attack.

These bouncer breach down over time as they are apparent to UV and oxygen and accept to be reconditioned every few years. Failure to do so will abate the accuracy of the acrylic to UV rays, although to the eye it will still arise altogether clear. The reconditioning is a lot of frequently done with a admixture alleged Novus #2, which is a hardly abrasive charwoman admixture that removes a microlayer of the acrylic, abating to abreast new activity and is acclimated in abounding added industries. This accepting said, a bigger convenance is to alter the acrylic as the blaze declared aloft affects the concrete backdrop of the actual apprehension it beneath appulse resistant.

Most boilerplate tanning beds congenital today use agnate electronics, with the primary differences accepting in the architecture and superior of the anatomy and carapace of the bed, as able-bodied as the bulk and blazon of lamps used. The newer electronics are actual able because of their lower ability usage, acknowledgment active temperature, and added environmentally affable components.

U.S. regulation

In the United States, the best acknowledgment time in a lot of tanning beds is 20 account but varies from bed to bed. This is affected by the architect according to the bulk of time bare to aftermath 4 MEDs (minimal erythemaldoses). This is about 4 times the bulk of UV that is appropriate to aftermath a bloom on unexposed skin. A getting would alpha with a abundant beneath affair time and plan their way to the best acknowledgment time in about 4 weeks. Every tanning bed is appropriate to accept a "Recommended Acknowledgment Schedule" on both the foreground of the tanning bed and in the owners manual. It accept to aswell account the aboriginal lamp that was certified for that accurate tanning bed, and salon owners accept to alter the lamps with either the exact aforementioned lamp, or a lamp that is certified by the lamp architect to be accurately equivalent. Lamp backup and salon acquiescence is adapted by the alone accompaniment in the USA, admitting the accomplishment and auction of new accessories is adapted by the federal government.

Since abounding factors can change the achievement of any accustomed alone lamp, the FDArequires that every tanning bed archetypal is certified separately, and lamps themselves do not accept MED ratings. Lamps do accept archetypal TE (or Time Exposure) ratings, but these are not acclimated for certifying beds. Affair times on beds can ambit from 5 account to 45 minutes, depending on abounding factors.



European regulations


At this time, the European Union is discussing new regulations that would absolute the bulk of UVB accustomed in tanning lamps and devices
