Context:" <response>: ```One very small amount of water vapor inside light bulb fit affect lamp darkening well well. Water vapor dey break into hydrogen and oxygen for the hot filament. The oxygen dey attack the tungsten metal, and the tungsten oxide particles wey come out dey waka go cooler parts of the lamp. Hydrogen from water vapor dey reduce the oxide, e dey form water vapor again and e dey continue this water cycle. The same as one drop of water wey dey spread for 500,000 lamps go increase darkening well well. Small amounts of substances like zirconium dey inside the lamp as getter to react with any oxygen wey fit come out from the lamp components during operation.```
