The linear Q H lamps at church seem to fail fairly frequently, which is awkward as they are so high up. They normally run for more than an hour.
In contrast, the security light outside my garage seems to last fairly well, for several years. Maybe this is because it is only on for short periods, and so does not get so hot.
The 24V 50W Q H worklight on my lathe used to eat bulbs, until I filed two slots on opposite sides of the reflector, to improve ventilation. Since then (asking for trouble!) have had no failures. Just as well as around here, (East Anglia) none of the electrical stockists, trade or retail, seem to stock. Fortunately, when I could, I bought a load for stock.
Maybe the problem is related to: frequency of "switch on", (current surge of cold filament); length of time running; ventilation; or a combination of these factors.
Certainly, normal GLS lamps do not like running cap down, (possibly lacking the ability to dissipate heat into the cap, fitting and wiring?), and are reputed to be designed to run cap down.
All types of Fluorescent lamps are better if left running for long periods; again no doubt, because of the effects of the voltage surge generated by the choke and capacitor to make the tube "strike".
