I am going to replace my fluorescent lights in the garage with regular fixtures so I can use screw in bulbs. When I took down one of the fluorescent fixtures there were 3 hot wires wrapped together running to the fixture and 3 neutral wires wrapped together running to the fixture. There's 1 ground wire. Why the extra hot and neutrals? Can I simply cap off 2 of each and wire the other 2 to my new fixture?

Thanks
