i just tried doing this,
in the process i nearly fucking killed myself,
i got a massive electric shock and everything in the house turned itself off, my heart was racing and my muscles twitching all over my body.. !!
always wondered why the UK went w/ 220 volts for standard wiring.anything over 200 volts hurts like a bitch.here in US we use 110 volts,it doesnt tickle but not as painful.I will swap a outlet or lightswitch live because I am too lazy to walk to the breaker.
it didint have a positive or negative side so did it matter which way i did it?
it does matter which way its done. if you look at the screw thingies(aka screw terminals) you will see 1 leads to the center post of the bulb & the other leads to the base that the bulb screws into.the 1 that goes to the center is your hot leg & gets the brown wire.my guess is you wired it bacwards and had the hot wire going to the base so when you touched it.....
if/when you try it again, wire it up,set it down and plug it in carefully.
you got zapped because you were touching something grounded when you touched something hot.
quick lesson about electricity,it is looking for a path to the earth,also called earthground or just ground. it can travel through your body to get to ground.
common paths to ground is the blue or green/yellow wires,any water pipe,concrete in contact w/ the earth or any metal in contact w/ the earth.if you are wearing dry rubber soled shoes and not touching anything grounded,you can touch the brown wire while it is plugged in.grab a water faucet while holding the wire & the current will travel through you to the pipe to ground.
work carefully & pay attention to grounds and you should be OK
