Most tanning beds use choke ballasts, a technology that has been around for about 100 years, consisting of an inductor which limits amount of current passing through, and requires a lamp starter to preheat the ends of the lamp briefly at start. Newer ballast systems include magnetic ballasts, electronic ballasts and more recently high frequency ballasts that induce tanning and other fluorescent lamps to work using less wattage, by using higher frequenci Wed, 10 Oct 2012 09:25:05 +0000 http://conservativehome.blogs.com/localgovernment/2012/01/councils-should-offer-real-help-now-to-families-cost-of-living.html#IDComment459718396 http://www.kabobfest.com/2010/08/7-girls-arab-guys-hit-on.html#IDComment459712260 Another trend is spray on tanning (a form of sunless tanning), using either special booths or a hand held setup similar to an airbrush. Many people who try spray on tanning often still go to the tanning salon, and use the spray on as a way to jump start the appearance of a tan, while others use it as a way to look tan while avoiding UV exposure of any kind.

Many people[citation needed] are now opting to own their own tanning system instead of going to the salon. The primary reasons are for convenience and privacy.

They are much more expensive to operate, thus more expensive for the user. Retail prices in the $20,000 to $35,000 range are common with individual sessions costing $20 to $45, depending on the market.

The lamps are still fluorescent type, using special phosphors that create a spectrum in the UVA and UVB range.

In addition, states have the opportunity to offer regulations for salons themselves, regarding the operator training, the sanitization of the sunbed and eyewear, and additional warning signs.

These are much more expensive, thus less commonly used. A tanning booth is similar to a tanning bed, but the person stands while tanning and the typical power output of booths is higher.

When not used for sleeping, the lower bed, with mattress removed, may be used as a general storage drawer.
