hey man circuit breaker was X n X i agree....but i think fuse should be 0.2 A because 0.25 is full brightness and lamp ratings are of norm brightness so then wouldnt fuse have to be 0.2A ... i mean ne higher than full brightness means the lamp blows up rite so then 1A is 4 times that value....someone reply

lool if u used a 0.2a fuse, then it will melt before the lamp will work (in its full brightness)
for the circuit breaker, it has to be on the live wire along with the fuse

agreed...i completely agree wid u....
if its a .2 amp fuse,, the fuse would break too easily and frequently...it would be pointless
