Halogen and Hybrid Fluoro lamps are breakable, but these small lamps are not built like the large suspended elements found in 240 volt lamps in Australia or 110 volt lamps in the US, which you only have to shake a bit and the filaments break. These quartz lamps are the same as the ones fitted into car and truck headlights, the very ones that can go for a rough ride in a four wheel drive vehicle over a corrugated dirt road and still work fine. My guess is that the rock and roll from large earthquakes would have no adverse effects, because these quartz lamps are well proven in road vehicles. Hybrid Fluoro lamps are so tough they need to be physically crushed to put them out of service. In any case, all the more reason to build a bungee rack for fragile gear and store extra spare bulbs in advance.
These lamps are all 12 volt quartz Halogen, using low watts, but because of the nature of low voltage, the low watt quartz Halogen light in lumens is quite significant and may be the answer to lighting in the aftertime!
