I was looking at Lamptech and some other resources at gas fill types for fluorescent tubes. All I can consistently find is that normal-output T12 tubes have approximately 3 torr of argon inside. Well that is all fine and dandy, but not all tubes are T12 NO. Are the gas fills for HO and VHO the same as NO? How about krypton tubes, are they pure krypton or a mix (and at what pressures)? I hear there is xenon and neon in some other tubes, what pressures are those at?

Does anybody have a chart or resource (or just know off the top of their head) what fills are in different diameter and different output level fluorescent tubes? I would like to add this to my public lamp spec sheet.

European T8 lamps have krypton. European "Eco T8" and "Eco T5" lamps have xenon. American VHO T12 have Neon. F34T12 have krypton and external conductive coating.
