Do you have further information on this? I understood that avoidance
of switch-on surges gave only minimal extra life to GLS lamps, though
considerable extra life to halogens.

As anecdotal evidence only...
I've noticed (as have others) that side-mounted filament lamps don't
last long, typically a few months of normal useage. Since powering a
desktop lamp through a push-button dimmer and using that dimmer as the
only on/off switch the same bulb has been in that lamp for the past 4
years. Ordinary 60W bulb, btw.

Many dimmers don't let you achieve full brightness. The bulb may
randomly have longer-than-average life. Some "ordinary" bulbs are
long-life versions (with slightly less light output).

So I am not surprised.
