My light bulb?

Question

doesn't say how many watts are on it, and I don't know how to use it :P

It's a black light, so it doesn't say it on the top of the bulb because you wouldnt be able to read it.

It is also one of those ones that you just like plug in kindof (rather than s******g)

On the side it has tiny writing, I think its probably the watts, but please tell me what kind of light I have to plug it into :P

This is the writing:

- 23QV75W -

Answer 1

This sounds like a type A bulb with a bayonet base.  Type A's have a spherical shape, extended at one end with a base attached; usually, these are threaded to be screwed into a socket, but some are bayonet base, with a cylindrical contact with a couple of small pins that keep the bulb in a socket with a slight twist.  These bulbs contain a filament in series with a mercury capsule; the filament throws visible light which is absorbed by the black glass, but the mercury capsule throws ultraviolet light which can penetrate the glass.  These bulbs are typically 75 watts, as implied by the legend, but the rest of the legend is probably 230V -- i.e., it is intended for use on 230 volts -- which conforms to the bayonet base, which aren't often used on 120 volt bulbs.
