I just picked up a 24 inch dual bulb fluorescent shop light from lowes. I got two t8 18 watt ge aquarium lights. The light didn't come with a power cord, just a ballast with wiring. I have white and black wires not connected, I'm assuming I use these to wire the power. How do I wire it to an ac plug? Doesn't need an on off switch, I will just hook it to my timer.
