It's not only the quality of the lamps that's the problem, it's the quantity.
If you have a single lamp in the centre of a room, as we used to, then, if it has a rated life of 2000 hrs, then you would expect to replace it after 2000 hrs of it being lit.
If you have ten downlights in a room, each with a rated life of 2000 hrs, then you can expect to replace a lamp every 200 hrs on average.
