That's not really surprising for a lightbulb that gets used for maybe 10-15 minutes per day :-)
Probably more than that; it's on a motion detector. It's intially on for 15 minutes before turning itself off. Then triggered by wildlife or SWMBO's arrival and if she doesn't turn it off, it keeps being randomly triggered until the following day. This is precisely the condition that kills CFLs.
While you can leave your CFL on constantly to achieve the rated lifespan, the fire service recommend turning them off when leaving a room as they occasionally catch fire.
Yes, I would have gone LED as I said in an earlier post, but $AU60,000 seemed a bit OTT. The double glazed windows only cost $AU30,000!
