if you have a roomy hall, or a spare corner, you can have a table or standard lamp or uplighter, which is less troublesome than altering your ceiling fittings. As they run off plugs you can more easily have them switch from Daylight in the morning to Warm White when evening comes, which feels more natural and helps the body clock. For some reason SAD lights are set to illuminate ceilings and you can't usually see the lamp directly.
I don't like spots or downlighters, unless you want puddles of light in a dark room.
Warm White lamps are marked 2700k and daylight lamps at about 5000k I think, but I only ever get 2700k
You can still get long fluorescent tubes, but in a house (or hotel) they would usually be concealed by a pelmet or something so you only see the light they cast on ceilings and walls.
Halogens are whiter and bluer, but cost much more to run, and give out a lot of heat. Try to use something cheaper.
CFLs and LEDs cost about the same to run for the same light output, but LEDs are currently more expensive to buy.
