Get a deep cycle 115AH 12 volt (1300WH) battery and string some 12V
lamps around. It all depends on how much you want to spend and how
they need to run.
CY: Spend: As little as possible. How long: About two hours. We
arrived at 6 PM, and the meeting broke up about 8 PM. About an hour of
that needed light.
You can buy standard incandescent MR16 20W flood lamps
for less than $1.50 each. You could run 10 of them for several hours
from a marine battery. You can buy LED MR16 lamps but they're much
CY: That's an excellent idea. The wiring wouldn't be too bad. The
farmer was thinking to run some kind of 12 volt lights, and then be
able to power the lights off a tractor or golf cart.
Probably four propane lanterns would be the most cost effective.
CY: Yes, that's better. As small as the pavillion is, one propane
lantern would do the job nicely.
