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? You do not save much if any
energy if it is only turned on for a couple of minutes and the
manufacturing process is not very green when compared to an ordinary
cheap filament lamp.

You salve your conscience if you are gullible enough to be taken in by
the hype surrounding all of this.
