I found the silicone insulated cable, RS Components part 192-7940. Thank you. This cable is rated to 180°C, so much more suitable for use near a hot lamp. Whether it would survive prolonged direct contact with a halogen bulb, I suppose I could find out by experiment on the kitchen table...

Can ANY cable withstand direct contact with the back of a GU10 bulb? I had a quick look for heat-resistant cable, plus a search for the surface temperature of halogen bulbs, and it looks like the answer is going to be no. If I use flexible cable, there is no guarantee that the cable won't...

Thanks for the suggestion, but I don't see how 3-core flex offers any advantage over twin-core+earth cable. Being the lazily person I am, I don't want to bother joining the earth wires together all the way along the light run. Possible reasons that I can think of for needing an earth wire...
