Overhead commercial lighting voltage is 277 so its less current and less
dangerous, but what if a contractor is still more picky?

I'd like to correct your thinking above.

While it is true, that a light using 277 Volts will draw less current

than a light using 120 Volts, assuming equal wattage lights,

it is false, that 277 Volts is safer than 120 Volts.

The 277 volt line may only deliver 1 amp to the light, it most certainly

could deliver several hundred amps for a short time and 20, 30 or even

50 amps continuously.

In any event, the power of commercial (even residential) wattage is
dangerous, but with more of it in voltage, its safer.

Please do not post rubbish.
There are some people trying to learn here.

The wattage used has no bearing on the risk of electrocution.
Any voltage above about 50 is considered dangerous and 240 is worse
than 120 and 270 ia worse.
The current will be dependant on the circuit resistance.

Please go and learn some basic electricity before you make foolish
statements. :-?
