Didn't look @ specs to realize PSU is only for 220v NOT 220V/120V switching. Light power supply is for 220v but seems to still work @ diminished capacity @ 120v. But not sure if arc is strong enough to provide UV @ 120v or is just making visible white light. Just make sure you're not ordering for the USA.

The first one I received was broken. They replaced it for free. New one works well. It cleared up the green water within 3 days.
