This A19/A60 vintage bulb has a smoked glass color, which is a necessary factor for antique lamps. But why it is smoked glass color? The reason is that when we manufacturing vintage antique bulb, the filament must be coated with red phosphorus for a longer lifespan, as red phosphorus will eliminate the oxygen inside the bulb, the red phosphorus will be evaporated when the vintage bulb is lighting on and the filament creating heating, and when the vintage bulb is lighting off, the bulb is cooling down, some of the red phosphorus will stick to the glass, it will make the glass looks like smoked. That is why quality vintage bulb is with smoked glass, just for a longer lifespan, and it is not smoke on the glass, it is red phosphorus. So no worry of the quality when we see the smoked glass for vintage bulb.
