i used tri chip led tubes. they are very bright and draw very little power. i got them from http://www.oznium.com/tri-chip-led-tube
heres a pic showing how bright they are.
Depends on the use and what you are trying to illuminate.
I am off to visit a supplier about using some of these for drive illumination - in this case a very low level of light is perfect (for walking really) and they will only be in use for a few minutes per day.
