You can use it no problems... its silvered copper wire is it not?? Will conduct very well and you can solder to any point as its pre tinned.
But... being single core it is not as pliable as the multi core stuff and snaps easier... all flouro lightboxes must use single core but it should never be used for mains in case it gets broken along the line somewhere
Yeah silvered copper and I tried bending it back and forth maybe 30 times and it didn't break but thats not saying it broke the copper inside the silver.
The only issue I can maybe see is replacing globes where you need to bend the holder to get to them. Dunno if they could break the wire??? Thanks for your reply
