Best option is a good quality LED bulb. They are supposed to have a life up to 50,000 hours and use about 80% less energy than a conventional light globe (and less energy than cfls for the same lux output). Unlike compact fluorescent bulbs (cfl), they don't need time to warm up to achieve their maximum light output.
They also run cold unlike other forms of light which means they should be a lower fire risk, especially when used in the ceiling cavity.
They will replace almost all bulbs, except those in high temperature environments such as the oven light.
They may cost more than cfls, but in the long term they pay for themselves with lower energy use than cfls.
We have gradually replacing our cfls with leds and wouldn't ever use a cfl again as the led performance has been great.
