What sort of tubes are these, are they the tanning lounge U.V. tubes?

Yep exactly. 100 and 120W. I was by bike and these lamps are really too long for a travel I just rescued a seventys Philips ww 40w T12.

S'pose these are pretty common in Bavaria. Here in Australia a Chinese Malaysian Girl died of skin melamoma from using one of these tanning beds. The Government had a crackdown and they are very rare here now. I have some 100w Ralarium brand Calcium Plumbous Metasilicate Phosphor ones, which emit at about 365nm.

The picture was takken in Hessen. However these aren't rare lamps anyway. BUT to say you the truth I don't think much of solarium visits. Here is enough sun for free

Well it is summer over there now, but its a but dark and dim here at the moment, but we don't get snow, too much ocean around us!
