    Not sure whether this is the correct forum to use - I have seen that members say return pumps will only work when you use a true sine wave inverter. is that also the case with LED lights?

    AC pumps requires a pure sine wave to run, DC pumps can run on modifies sine wave... leds, T5 can all run from modified sine wave...

    Basically anything that has its own power supply will run off of a modified sine inverter. Many AC pumps will work as well but there has been occasions where the AC pumps did not work.

    Thanks for the feedback. I spoke to a UPS suppliar and he said I can bring a spare return pump to the shop and then they can test it before I take a decision.

    The LED lights I was referring to is a Maxspect Razer - so you do not think I need to test that as well?
