* A bed was designed to operate with a particular type of lamp (or a compatible replacement) to achieve the session length it is labeled with. The following factors of bed design play a part in the session length:
-Ballasts -Reflectors -Acrylics
-Voltage -Distance between lamp and the tanner
* For example, if you purchase a tanning unit with a 20 minute session length, the lamp that it came with was designed to tan up to a 20 minute session length in that unit. If you install lamps with a higher UVB ratio, it may reduce the exposure time significantly.
* Some state and FDA regulations may allow you to re-certify your tanning units for use with a higher UVB-rated lamp. You will have to change the exposure schedule accordingly. Please contact your inspector for more information concerning re-certification.
