LED's consume much less power than fluorescent lamps. And last much longer.
Machine B will use more power.
It depends upon power of phosphorescent light. The power determines energy consumption.
Power = Voltage x Current. So it will be 60W of power consumption, in your case.
Depends on size - all will have a rating (power consumption) quoted.
Power = Voltage * Current Current = Power/Voltage, = 2,750,000/110,000 = 25 amps.
Not much, but it varies from machine to machine - a watercooled gamer computer needs far more power to cool it than does a laptop.
This will depend on how hard you are using it. If the machine is idling, it is not going to use as much as when you are using it full steam.
