Wrong Starter for Fluorescent Light

I have a twin fluorescent light fitting in the kitchen.

I replaced the starter on one side but the starter was 100-125 Watt and the tubes were 70Watts.

It worked for 2 days then the lighting trip went up. It has not worked since.

The other side is fine and works as normal so we have one working tube.

What usually happens of you put a heavy starter into a lighter tube?????

The starter in a fluorescent fixture is there to cause current to heat up the ends of the tube for a few seconds, then cause the high voltage to light the tube.

If the starter was too big, it would either burn the tube out, or burn up the ballast. Pretty much a toss-up as to which one.

Try putting a known good tube and starter in the fixture that doesn't work. If it still doesn't work, the ballast is very likely bad.

Are you sure we are talking "starters" and not ballast's (transformers). New fluorescent fixtures very seldom use starters any more, if at all. The newer fixtures have rapid start ballast's in them and require no starter.
