Did you guys know that the little 22 gauge wire that your telephones are using is carrying 48 volts dc and 90-100volts ac while its ringing and it goes for miles before the phone company uses repeaters to bring the volts back up. In highrise offices the volts are 24 and on 24 gauge wire. Unless you are pulling allot of watts on the other end, a light bulb can use 12 and under to be safe. But if it’s just an led then small wire is fine.
