I have a 5mtr roll of 5050 SMD led's. I want to make up a couple of light sticks to use. Just after some ideas on what to use for the backing. I'm thinking of making them around a metre each with something on either end so they can be hung up horizontally. I'll put in the wiring a little rocker switch so they can be turned on and off with ease too.
Plus what size wire would be good to use? I was thinking of 3mm twin core or maybe 4mm sheathed twin core for added strength as I would want to make the leads around 5 metres each, maybe longer...

Thanks.
