Maybe. Depends on your troubleshooting skills.

You likely have a wire connected to the wrong splice. Does it pop the breaker without a bulb installed?

Thanks! im up for a challenge

It does not pop the breaker. It is one of 3 ceiling fixtures and im using the other 2.
It used to work, and then suddenly the bulb in the fixture stopped working, so i put in a new bulb and that one immediately fused. that was a year ago and havent tried since.

Try one of the known good bulbs. What type of bulb are you using, incandescent, LED, other?

Take a multimeter (set for 250 volts) and measure the voltage at the socket. Or take the fixture down and measure the voltage where the fixture wires connect to the house wires. You should get 120 volts.

My guess is the cfl that tripped the breaker has a problem. The difference in load between a 5W LED and a 20ish (?) cfl is minimal. Do you know what other lights or other loads are on that circuit? What size is breaker that is tripping?

thing is Bud, it used to work on a CFL that was like 15-20W then it stopped working after like a year. I replaced with another 15-20W cfl which immediately stopped working. That was a year ago. Yesterday I put in a 5w led and it still works now.

the kitchen has 4 light fixtures like the picture below, the other 3 have 15W cfl bulbs. The breaker never tripped that i remember.

You keep using words like "tripped" or "blows fuse". Exactly what is blowing or tripping?

well the bulb is probably what blew a fuse internally. no breakers tripped. the fixture is also fine, apparently.
