Tanning Bed Bulb Replacement Tips

By Mattie MacDonald


Many people love having a golden tan all year long. When seasonal changes make outdoor sun bathing impractical, it is possible to get similar results indoors using a tanning bed. Although commercial salons are always popular, increasing numbers of users are choosing to buy their own equipment. Regular tanning bed bulb replacement helps ensure optimal performance.

Hundreds of designs for these platforms have been created, but all employ similar operating principles. They are built around a padded, pod-like bed with attached cover containing the strongest light sources. The sources themselves fall into two categories, low and high pressure. They are able to produce high levels of ultraviolet rays, helping to limit accidental overexposure. Low-pressure varieties look like fluorescent tubes.

They work with a current regulator called a ballast. Like the neon signs that still brighten some city nights, light is created by exciting the phosphors that coat the interior of these structures, producing photons similar to solar emanations. The glass used for the exterior acts as a UVC (ultra-violet C) filter, allowing only the radiation effective for tanning to reach and interact with human melanin.

High pressure lamps are usually called bulbs, and differ considerably in size, shape, and output. Often used to target specific areas such as the face, they are usually less than five inches long, and range from low-power 250-watt models to high-performance 2000-watt varieties. They generally produce only UVA, making them an integral component of medical sterilization procedures.

Light sources of both pressures have a general life span between one and two-thousand hours. They are optimal only for the first fifty hours, after which they gradually begin to lose efficiency, becoming largely ineffective as ultraviolet sources. They may still produce visible light, but not tanning. Most home users learn to replace old bulbs at half their estimated life, between 500 and 800 hours.

Because of this typical decline in performance, it is advisable to swap out all high-pressure bulbs at the same time, or at least rotate them to different spots. Not only does this increase their overall effect, but it also encourages even coverage of all skin regions. Individual skin reactions to exposure also vary, and what seems overwhelming to one user may feel ineffective to another.

Unlike the bulbs used in standard home lighting, different brands are not always interchangeable. Using the wrong strength unit may cause electrical malfunction, or produce too much heat. To be safe, keep all installation information originally included with the unit, and when necessary only buy replacements from the original dealer. Never economize by purchasing an off-brand, because the results can be costly.

Purchase only those bulbs that match UVB and UVA exposure limits precisely, and consider keeping spares on hand. Some users prefer buying fixtures in bulk, saving not only money, but the headache and annoyance of an unexpected equipment failure. When questions arise regarding availability or upgrade of maintenance products, the dealer who sold it can provide information regarding safe, compatible replacements.
