brian i dont think you are correct i work in national lab and i work on alot of spectrophotometers and the blue glass is used i have never seen clear glass if you have info to back up your claim please give it out because i need to change alot of data from millions of experiments.i checked my beds and they have the clear glass next to lamps and blue FILTER glass farthest away who is correct.

brian i ment to say the blue FILTER glass is next to my lamps and the clear glass is farther away.WHO IS RIGHT im glad we have this board to sort this stuff out.

I have seen it both ways, with the clear glass next to the lamp, and also with the blue glass next to the lamp.I have 2 meters, one is a UVA meter and the other is a UVB meter, i will check the output of a 400w facial lamp, thru the clear glass and also thru the blue filter glass and will give you my results of the UVA and the UVB.

Ever wonder why your face tanners or high-pressure units don’t seem to work as well after 700 hours as they did when the bed was new? This is due to a phenomenon called “Solarizing”, which effects all Blue and Black Filter Glass used in sun tanning equipment. UVA is transmitted, but virtually no UVB - a principal requirement in the tanning process - is allowed through. Most photobiologists agree that PURE UVA IS HARMFUL TO THE SKIN. JUST LIKE LAMPS, THE FILTER GLASS NEEDS TO BE REPLACED PERIODICALLY TOO! http://www.google.com/search?q=cache:www.amexport.com/vistalite.htm+uva+suntanning+lamps&hl=en

Sounds very risky to me!Salons that don't know a thing about the filter glass in their facial tanning units.They don't have even the basic understanding!!!Clients you are at risk for extremely high cancerous UVC rays and sun burning from facial tanning bulbs if the filter glass is not installed right or has been replaced with non factory approved replacement filter glass!!!!!

chipp the factories will tell you to go buy it from the parts suppliers in the catalogs and please tell me the difference from the blue glass in my beds and any other bed,do certain beds have a different transmittance for there glass or what.

chipp why would the facial glass need to be replaced if all it needs is cleaned,are you saying to throw my filter glass away for some reason,lets get back to the basic question,does anyone have documentation to back up which way the 2 layers of glass are in a facial one BLUE FILTER GLASS AND ONE TEMPERED CLEAR GLASS.please answer the question with documentation .

When only a blue filterglass is used it is the UVB filter. When a clear glass and a blue glass is used the clear glass is the UVB filter. In this setup the clear glass is closest to the lamp and the blue is closer to the client. The most current blue filter is MUG6. Oh, and hoser, you don't even have any equipment with high pressure so you have no idea. And again, filterglass does not solarize.------------------Friends help you move, Real friends help you move bodies.

brian if that is the case my beds are all wrong from the factory,all my royal sun facials are blue glass next to lamp clear next to tanner and i dont think it can be switched because the glasses are different thicknesses and wont swap . what problem would i ever encounter if any,thanks again for all this info.
