I've had 3 or 4 bulbs blow in the last couple of weeks on one fitting. It's a flush mounted ceiling light, I've been up and checked the fitting which is reasonably new, the whole house was rewired 5 years ago, there's plenty of space around the fitting in the loft space (insulation pulled well back), etc.
Why? Could I be that unlucky with a bad batch of bulbs? Worth replacing the fitting or something else to consider.
BTW as part of the rewire we have a RCB installed and that doesn't trip as the bulbs blow if that's any help.
