Cable to outdoor lamp too short

[MrsRenovator]

Hello. Hope you can help.

I fitted a Lap LED floodlight about a month ago. Hurray! We have light! Or, we had light. Whoever the numpty was that had fitted the old light, they had cut the 3 core cable to within 3" of the wall. I managed to connect the new light with difficulty. But no room to loop the cable for drips. Also the waterproof gland on the lamp is designed for 1mm round cable. (Not the flat grey twin and earth) So now I'm not surprised that the light has become temperamental.

So if i get back up the ladder and put up a weatherproof junction box, (or an inline connector) where can I find the needed 8" of 1mm ho5rnf-3g that the instructions suggest? When I Google it I keep finding, 'not suitable for permanent outdoor use'. If I get rubber tuff cable I'm not sure it will fit in the gland of the light.

What am I doing wrong?

Probably worrying too much
I am sure for 8" any old round 0.75 to 1mm 3 core flex will do the job, black or white, even a bit cut off an old appliance

Bite the bullet and replace the cable rather than mess about with a junction box. Which, BTW, will also have the problem of glanding T&E into it.

Ah yes, that's a given. Great, I'll hunt through my cable box tomorrow.

I doubt very much whether i could successfully feed a new cable back through to the switch. Who knows how many bends there are on the way. Or if there is conduit all the way .I could end up without an electric supply to my light!

Yes you're right, the twin and earth cable won't fit perfectly on a junction box gland either. The advantage is, I can enter the box from the base, whereas on the lamp it's rear entry only, and with the lamp angled down towards the path any water on the cable would run straight in. So hopefully having round cable from the box to the lamp will give it a good seal.

What? Not another set of manufacturers instructions being wrong?
