If the building has a 480V/277V service and you have a lot of lights
to install, then the contractor can use smaller wire with 277V
lighting but will have to use more expensive lighting panels.
Also you will not be putting the extra current load on your existing
step down transformers if you use 277V.
I would talk to the contractor and the owner and ask them each to
present thier case. As far as the lighting goes, there really isnt
much difference. 120V installations tend to be cheaper and safer
if you have enough power at that voltage.

I have a new small commercial building being designed and the building
owner wants 277 volt lighting and the electrical contractor would like
120 volt lighting. What are the advantages and disadvantages of both
systems? Help! Thank you.
