Multi voltage ballast

[Mack57]

I have some T8, 6 bulb, high bay lights that have 120/277v ballasts in them. I want to wire these lights to 120V. The fixtures have red, black and white wires for the connection to the power supply. Do I wire the red and black wire to 120v hot leg? Or do I just wire the black wire to the hot leg and cap the red wire?
