Can I use speaker wire to wire all my projects? Is speaker wire same as regular

guys 600 feet right off the bat means about 60 different LED runs at less than 10 feet each - which is less than 600 feet

I just need to use it to light LED's in series, pretty much holiday lights that will blink to my liking.

Im getting people saying this that, when Im thinking the ampacity isnt going to be high for 5 5mm led's

I should be able to use fire alarm wire shouldnt I. Doorbell wire would work as well wouldnt it?
I saw the speaker wire on ebay and thought it was a great price -- but Ive come across some other auctions and think I might go after them

But for future reference, can I use speaker wire?
Its copper.

I was just wondering if speaker wire would impede more than regular wire would?

But am I safe to assume that I could get away with doorbell wire, or alarm wire, so long as the ampacity requirements will cover the 5 led sets I want to use?
