Some designs of low energy bulb are better than others in this duty
cycle, just like some designs of GLS bulb are.

So the advantage of putting a relatively expensive low energy lamp in
such a location would be what exactly?

Not having to replace the bulb so often. Reducing greenhouse gas
emissions.

You do not save much if any
energy if it is only turned on for a couple of minutes

One will indeed only save a little energy over the space of a few
minutes. However, little things add up over the years.

and the
manufacturing process is not very green when compared to an ordinary
cheap filament lamp.

That would be a factor, if both types of bulb lasted for the same
time and used the same energy.
