Mike,
Last time I did outdoor lighting it was for a mini Golf Course that someone had put in their back yard. Putting the lights (small Halogens) up in the trees to shine down gives a nice effect. These were put on dimmers that could be controlled from the house.
As far as Garden lighting goes I like the low voltage stuff. (metal, not plastic fixtures). They have a lot of nice looking styles and it's very easy to change and move fixtures around.
