Yes, A dim bulb is extremely inefficient, it will use a lot of electricity for a very small amount of light.
On the other hand you can make very efficient lightbulb that will be very bright for a small amount of electricity but last only for a few minutes.
The 1000 hours limits is a nice middle ground.
And what of the noble gas filled bulbs that were both brighter and longer lasting?
i mean, all incandecant bulbs are filled with a noble gas, Argon. If they didnt any bulb would have a lifespan measured in seconds.
Back in the 1920's and earlier they were commonly just in a vacuum.
