I "inherited" a bunch of Anglepoise (USA: Luxo?) lights from a closing down typography studio (greeting cards!), with 80W 240V halogen lamps in they give a light good enough for my old deflicted eyes - and the halogens are full-spectrum so they give daylight-like colour rendering, something compact fluorescents definitely don't!
On the lathe I've got a 50W 12V halogen in the original worklight (they're available in a bunch of different beamwidths from 10 to 60 degrees), with a bit of bodging to fit the holder in place of one for an Edison Screw 50V incandescent - the orignal LoVoLite 50V transformer (415v in) has been replaced by a 12V 60W electronic "transformer", only £3 from the local TLC electrical wholesaler!
Fluorescent lights... Hate 'em, just on colour rendering if nothing else, and they can "strobe" rotating machinery so it appears to be standing still - not a good idea.
