While possible to do what you mention, there are a few concerns. Both power cords on one side makes a larger set of wires running down the same side of the fixture. We wanted to keep it a little more symmetrical.
Allowing the dual lamps housing to be flipped would place the ballast channel toward the center of the fixture and a set of lamps toward the edge of the light, possible but not what we figure people would want.
The extrusion of the fixture only has a certain set of points that allow screws to be anchored to the plate. The end plates would have a lot more holes in it to make it more universal.
We are open to suggestions and will try to use them to improve the product.
So if I do the math there's six feet of cord coming out of the end of the light. It's 4-5" to get to the cord notch and then another 36" of light. So out of 60" I have 20" of cord left to make it to an outlet. My suggestion is if the cords need to come out of opposite ends there should be more than 20" of play.
"Allowing the dual lamps housing to be flipped would place the ballast channel toward the center of the fixture and a set of lamps toward the edge of the light, possible but not what we figure people would want." Why not flip them in the other direction?
