110 is the way to go...if you went 12vdc you need heavy wire
to get the lummens you need, and those tend to corrode and
components are not common.
Heat is a problem though with incandescents, but that gives
the best broad spectrum light, showing up color well and
healthy for the tree.
Maybe warm *full spectrum..fluorescent flood bulbs would work,
they max out at 100w though. if you dont like them you can
screw regular incandenscent outdoor floods or spot bulbs
in...you can run 14/2 to the individual lights...that will
carry 9 amps steady. (1000 watts at 120v)
You will probably want some 200 to 600 watt spots to light the
top of the tree. you could easily have 1000 watts on that
thing...thats 9 amps... 12/2 would be fine. Myself I would
pull at least 10/2 in case I wanted more light... the 12/2
maxes out at 15 amps (steady) 20 is just the max limit.
