High pressure tanning beds use quartz lamps that may vary in length. The older style bed tanned the body from above while the tanner rests comfortably on a contoured mattress.  However in recent years vast improvements of the high pressure beds have led to products like the Convex tanning bed which tans the user from both sides making it much faster.   The term "high pressure" comes from the manufacturing process of the bed, which maintains the gasses inside the quartz lamp at a little above atmospheric pressure, while the gasses in the tanning tubes of conventional tanning beds are held below atmospheric pressure. Most high pressure tanning beds have an elaborate ultra-violet filtering system, which blocks the UVB rays almost entirely. Some of the more advanced systems even remove the higher frequencies of the UVA rays, leaving only what they call the safest, most effective part of the spectrum to provide a deep, dark & long lasting tan without a high risk of burning.  Additionally, a second filtering system removes a large percentage of the infrared spectrum for a 'cooler' tan, and also the bright white light is toned down for a more relaxing and comforting environment. The difference is a higher quality, faster tan.  UVA is what is responsible for a lot of the deep photo-damaging (elastin damage).  This is why filtering most of the UVA spectrum is sought after.
