I'm looking to install some new 4 foot 4 bulb T5HO fixtures in my garage and I've noticed that the balasts say that they can be wired with either 110V or 220V. My question is, is there any benefit to wiring them up in 220? The downside to me seems like it is a lot more work and extra materials/wires to run an extra hot to every light fixture in the 220V configuration. Is there a reason why anyone would choose to run the lights in 220V?

Thanks,
