My concern would be that the bulb may not be making good contact with
the lamp socket. If the connection is loose, excessive heat will be
generated and cause more damage then from overtightening.

Yes, the best way is to see when it just lights up and then measure the
fraction of a turn to where it stops going further, then back off halfway.
Europeans say 1/3 of the way, but that's because they use the stupid metric
system (220 volts) as opposed to the imperial system (110 volts).
