1. This large size special shape decorative vintage led bulb has a semi-dark color glass bulb, we also call it dark grey color glass bulb, or black semi-transparent color glass. This glass is dark grey color, and transparent, just like the dark grey color glass bottle, or like sun glasses. In our factory, we call it smoky gray color.
2. This dark grey color is made by Plasma plating, so the semi-dark color is much even, and much beautiful! Also, there is several different dark gray transparent color, the main difference is its dark color, some is light dark, some is deep dark, different people has different preference, we can control the color definitely. However, there must be some color difference between different batch of production, because plasma plating always has such problem! But we can make the color difference as small as possible. For one batch production, bigger glass bulb has a little darker color than small glass bulb, because large size of glass bulb absorbs more plating than small glass. All these factors are the necessary information when we are producing dark grey color semi-black decorative vintage filament led bulbs.
