I would expect that they would be pre-setup for 120 and just need a plug. If you need to do any adjusting inside it looks like that color coded grid will tell you whats what.

AC fixtures use black and white for AC input wires. Get yourself a heavy duty replacement tool cord and some wire nuts from (insert favorite hardware store name)

Lots of sharp edges on fixtures like that so protect your wires and make clean tight connections. Wire nuts are more than fine allthough I solder mine.
