Default Re: lamp and glass change in magic

Jesus... you have TWO layers of filter glass and no clear???

Italian plus MUG-6? Weird!

ANY kind of glass (except quartz and fused silica) blocks any UVC from the bare lamps. Clear, blue, purple, green, orange, whatever...

Even though you are (now) getting normal 5.0 UVA readings... I bet your UVB and MED/hr are much too low due to two layers of "filter" glass. Didn't you learn UV-transmission basics at Circuit City?
