too many wires

I'm changing the ceiling light fixtures in my house, but one of the new fixtures has six sockets, and six pairs of black and white wires. One of the pairs also has a bare copper ground wire. The box in the ceiling has 1 white and 1 black wire, so I'm not sure what to do with all the wires in the fixture.

My assumption, which I don't plan to test, is that all the white wires from the fixture somehow need to be connected, and then attached to the one white wire from the box, and the same for the black wires.

I'm in the US, the wiring in this part of the house is from the 50's, and has no ground wire.

You are correct in your assumption about connecting all the wires of a similar colar together.

However, The fixture may contain a warning about only installing on wiring rated for 90 degree C. Your house will not have wire with the insulation rated that high. You fixture should NOT be used with the old insulation types. The heat from 6 bulbs will bake the remaining life out of the wire insulation.

I didn't see any warning on the fixture or in the useless directions. Would the warning normally be on the fixture itself?

The current fixture in that location has 5 bulbs, and has been in operation for about 25 years, so I'm thinking the wiring is capable, plus I will be using fluorescent bulbs rather than incandescent, which should remove any problem with the wiring, since they only draw about 1/4 as much.
