    Could you tell us what country you're in?

    Also, what do you mean by "2 red into a loop connection"
    It would be great if you could post a photo.
    Thanks.

    Hi
    I am in Australia
    Light that I took down had 4 terminals 2 were labeled
    Earth & loop
    The other 2 terminals had nothing & black & white wires went into each of the remaining terminals
    2 red wires were one red wire from each cable
    The cable going to switch has only red & white wire & other cable with red, black & earth goes to power
    No picture as already dismantled.

    Okay, if I am correct, in Australia red is live and black is neutral, earth should be bare or green. At the light switch itself, is the cable with the red and white wire the ONLY cable connected to the switch?

    Yes only the red & white at switch

    Okay, I don't much about Australian wiring practices, but I think I know what's going on, you have what is called a "switch loop" where power goes to the fixture and then to the light switch.

    You need to find a way to connect the red wire from the incoming power cable (red, black earth) to the red wire of the other cable that is going to the switch (the red/white cable). In the US we use screw-on wire connectors (like these: wire connectors - Bing Images). I don't know if they use these in Australia, or if they use something similar to British connectors (like these: 2.5mm Push-Wire Connector - 6 Pole - QVS Electrical Supplies | Electrical Wholesaler). Your local hardware store or electrical supply probably sells the connectors you need.

    So basically, the two red wires go together. The white wire will go into the "line/live" connection of your new light, the black will go to the "neutral" connection of the light, and the bare/earth connections will go together.

    Hope this helps.

    Yes it did it is what I thought but just wanted it clarified
    I am from UK & we would use a terminal block to put the red loop wire in. Hopefully have some in my tool box
    Thanks

    Just wondering, can you do your own electrical in australia, and buy your own Hardware? Or is it like a "protected trade?"
