How much electricity will I save running a grow light 240 volt?
There is no energy savings from running your lights at 240 volts. That is a misconception that many people have. The main advantage is the fact that you can run more lights on one electrical circuit. For example if you run a 20 amp 120 volt circuit, you can only run two 1000 watt lights on that circuit. If you were to wire the circuit up for 240 volts you can run four 1000 watt lights on that circuit. This makes for a lot less wiring but does not save you on your electricity bill because each light still uses the same amount of watts.
