Tommy:Interelectric is a very reputable company. We will test some more of their lamps after the 1st of the year. We have tested their Panther lamp that is designed for use in 10 minute MTI (maximum timer interval) sunbeds and it reaches 4.0 in slightly under 10 minutes.All 5.0 UVB lamps manufactured by a specific lamp manufacturer will be the same no matter what "private label" name is printed on them. That does not necessarily mean that it tests out at exactly 5.0 UVB but all of the lamps manufacturered in that "batch" will be the same. One of the reasons we set up the UVR Research Institute was to standardize the testing of lamps (and sunbeds). We think that tanning salon owners deserve to have an independent rating of sunlamps.Hope this helps.Don |
