I had the same problem with blowing globes on a regular basis (2-3 a week). The problem was solved by tightening the screws in the switchboard for both the active & neutrals for all the circuits in the board (the nuetral for the lights was two turns loose) & replacing the 240 volt globes with 260 volt OSRAM 'rough service' globes. Result: up to 6 months before a single globe had to be changed.
