If a sodium lamp it about 400watts it will be high pressure.
Uncertainty or not knowing causes depression, Im happy because I know I'm going to die one day!

Yes its a normal 400w high pressure sodium lamp that you may find in high bay luminaries and the like but with blacklight blue coating on the glass to filter out most of the visible light spectrum leaving mostly the ultra violet range. Its not atchelly just the ultra violet range because you would not see it if it was. I wonder if it would work out cheaper buying an ordinary 400w son fitting without the lamp and just buying a uv lamp to put in it.

All discharge type lamps need a ballast. Some lamps have internal igniters and some don't relieing on one in the fitting. You have to check you get the correct lamps for the fitting (or the correct fitting for the lamp as the case may be). The lamps with internal igniters have a little triangle symbol on the side with an 'I' in it. I am not sure if the UV ones have them or not.
