| Apr 24, 2023 at 1:07 | comment | added | Nedd | These are most likely halogen bulbs. In a halogen bulb the tungsten atoms that boil off the filament combine with the halogen gas while hot, when the bulb and gas cool the metal redeposits back onto the filament rather then on the bulb's glass (quartz). This prevents the bulb's inner surface from darkening. Obviously some of the tungsten also redeposits onto the cooler internal metal parts. | |
