    Are the lights rated for mains voltage?

    The controller to mains is 230v but the controller to the lights are higher I'm assuming the controller is some sort of amplifier? Please see the image attached maybe I'm doing something wrong

    I have no idea why you are getting that sort of voltage but if that was my multimeter I'd be inclined to throw it in the bin as I could never trust any measurement after seeing that.
    You should be getting a much lower reading going to the lights.

    Yea I think you are right it's a dirt cheap rolson multimeter I'm was assuming the light would be at 12v as they are led

    Try to check the voltage with another meter if you can.
    Can you open the controller and see what's inside it?

    Will do sir. Just wondering though I'm getting correct readings on the mains which is 230v?

    I don't know to be honest. The only thing I know is there shouldn't be 457 volts going to the lights so that's why I think that reading is wrong.

    You are probably right on this I'm just stumped as it shows the correct reading on the mains plug �� but not on the lights I was under the impression it would be the same or lower be for I tested it

    Try setting the multimeter to dc

    I’ve just re-read your First post, what exactly are you trying to do? If you connect those leds to mains you will blow them as the voltage would be way too high for them.

    I wanted to hang them outdoors I have connected them to a rf relay that can turn it on and off via remote problem is when I turn it off and back on it resets and goes back to the flashing settings I just want them to be on and not flashing or anything, if they need to have a lower voltage I can get a led driver for it just want to know which of those wires are the positive and negative from my finding (if I'm correct) the left most wire is the positive and the three other wires are the negative

    So on the multimeter at 500v DC it's showing me 200v DC I think that's the correct reading now right?
