Well let's clear up all of the myths here.
First, a Cayenne, E600, Cobra UXF are not High pressure beds, they are VHO beds that use florescent tubes, not full quartz lamps except for the facial areas. You did not tan in a high pressure bed.
As for the UVB content in High Pressure beds, it will be as much as 4 times higher than that of a base bed. Everyone needs to stop with
"PERCENT UVB!!!!!" This is not a reliable way to determine strength. It is amazing how uneducated most are in this industry about bed types, UV, the tanning process, business, etc... Anyway, High Pressure can and will burn you if you are overexposed. The difference is that the UVB in HP beds is more right shifted in the spectrum so it is not as harsh as the more left shifted UVB in the base beds but there is still a lot more UVB in HP beds due to the shear power of them.
Now things to look at on why you had the reaction that you did, are you on any medication that you don't usually take? This can make you photosensitive.
Was the bed used by a customer that used high tingle lotion and it was not properly cleaned before your session?
Is the salon properly cooled and clean or is it a hot box and filthy? If it is hot then it is possible that the lamps were not properly cooled in the beds and would have uneven output or if the bed is not well maintained then it would run hot and affect even tanning.
Did you apply your lotions evenly or did you rush and miss spots?
Did you eat something that made you photosensitive? Certain foods can do this.
There are plenty of things that could have taken place to get this kind of reaction. A couple of things that can fix this are sitting bent over on the lounge to tan the smileys.
Applying SPF to the dark areas and tanning so the untreated areas catch up.
Spray tan . (Holy $h!t, did I just say that?
)
Just let it go away and start over.
Another thing to look at is what kind of lamps are in the beds. Are they the same brand/make throughout all of the beds? Are they different in each of the beds? Are there only one kind in the bed or is there a mix of different brands and types? This here would signify that they just pop in what they have or just put lamps in when they burn out. Without actually metering the beds, it would be difficult to determine if there are strong and weak spots in the beds.
Are the acrylics clean on the inside? Are they old looking and crazed? It could be any number of things.
