yep, on the top of my reflector there is 2x electrical boxes and I wired half to one, half to the other. From there its just a extension cord out to the timing powerbar.
The reason I did it seperately is so that theres less stress on the cords, If something fucks up atleast I will have half the lights on. Easy setup, pretty cheap too. I got all my material from HD. Single sockets and splitters easiest way to go, you can order those splitters on ebay for 99cents a piece free shipping. They work better then the ones i got from homedepot.
