Hi, I’m wiring up an outside light from a junction box and have realised I’ve brought 1mm cable and not 1.5mm. Really want to get it finished today, Can I still use it? Its powering an up and down light with 2 x 5watt led bulbs. Thanks in advance.

Although it depends on where the junction box is supplied from. If it's a lighting circuit, the answer is a resounding yes. If it's not a lighting circuit, the answer may be a resounding no because the fuse/circuit breaker for the circuit may not protect the cable in the event of a fault.

It’s off a lighting circuit so perfect. Thank you!!!
