Best practice to extend short cable to external light

[DIYHacker]

Hi all

 

I need to move & replace the existing external light we have. As you can see its mounted to the board with the wire cut short. This light provides pretty useless coverage outdoors so I am going to replace it but would like to mount it on the other corner wall (as visible in 2nd picture) so I need to extend the wires to reach (maybe 20cm). As they will be exposed to the elements, what is the best / safest way to do this?! I will then mount the wire on the board, paint it etc so you don't notice it.. running new cabling is not really an option here.

Fit a waterproof external junction box in place of the old light and extend your cable from there.  Most LED outdoor lamps now come with a captive length of flex.

Easiest thing to do is to buy two lights, replace the original, wire up to original supply. Then run a new cable from the replacement light's terminals to the new light on the other corner. 1.5mm cable should be enough.

What Dave said. IP65 black junction box and extend the cables/connect the new light via Wago is probably what id do.

To join a cable I would solder the wires, use heat shrink tubes on each wire and also total external and wrap in tape self amalgamating.

Or … join cables with this gel box

Thanks all for the advice! Managed to get it sorted over the weekend and got it all decorated. Only bit left is to paint the bit of cable black when I sand down the board and repaint it.. Think it all turned out pretty good.
