Gday,
Im makeing myself a couple of camping lights and have found some cable in the shed left over from another job.
I think it is called twin active?
1.5mm sq
7/0.50 1.5 TAWH
450/750v Flat two core.

I know its for 240 volt, but what is wrong with using about 4 meters of it for my camping light???
I assume voltage drop? will it be noticable?

Cheers

Hairy

Hi Hairy

The 1.5mm twin active would ok for lighting as long as it is only low power. The main draw back with that type of cable is that it is not very flexible, far better to use some multi strand cable that is more flexible.

regards
Rocky

Sounds like the common figure-8 flex.
Depends what sort of camping light you are thinking of, but if you are using a CFL, these draw a bit less than an amp on 12v, and should work fine.
If you are thinking of an incandescent light, it might be a bit light-on (pardon pun).

Cheers Fellas,
Yeh I am using a compact fluro.
I will buy some 12volt if I get time...its just incase Id dont make it to the shops and have to use something laying around home.

What about the cable left over from my garden lights (12 volt I think)??? That might be better hey?

Cheers

The garden light cable will be fine. The types I have seen have more than 7 strands of copper

Use a cable with multiple strands of copper, not the 240V stuff as most of it only has 1 or 7 strands and it breaks very easy on a few corrigations. Its no designed to be flexible at all. Yes it will get you going but not a recommended thing to use a permenant. Garden cable would be ok just give the cable some protection where it goes through holes in walls etc.

Hi Hairy

As per others OK but not optimum

The numbers indicate you will have no voltage drop , and have 7 strands which again is ok but not Optimum

Thanks everyone...
I found an old cigarette lighter plug with a heap of cable on it,
Wired that through a bedside lamp with the bendy shaft and a clamp on it and put in a 12volt compact fluro.

Works great...

Remember to give the tube a squirt of yellow paint to keep the bugs away.
