Rep Power: 23 | A 20 Minute Session In A Tanning Bed Is Equivalent To How Many Hours In The Natural Sun? It is difficult to make a simple comparison between the sun and modern indoor tanning equiptment. Just as various kinds of indoor tanning and equiptment differ in spectral output and energy emitted, the sun's strength is dependant on several factors as well, such as the time of day or year, the latitude, cloud cover, pollution and reflection. Consequently, there is no formula for relating indoor tanning exposure times to outdoor exposure times. I think Don Smith knows this answer. Christopher can you see in achives under Ask Don if he did this study. I think I remember him having the exact answer here to this. Jim |
