1. This is a large size(oversized) thick frosted vintage filament led light bulb, size is diameter 143mm and 160mm length. Inside the white color decorative frosted light bulb, there is 4pcs 68mm length sapphire substrate filament led. Because this bulb is thick frosted white color, we can not see the led filament inside. However, as a lighting source, the filament design is very important for vintage led frosted light bulb and opal glass bulb, because the light output must be much even, no shadow, so the filament led must be spreading uniformly around the glass stem inside the frosted glass led bulb.
2. This is a outside frosted decorative led bulb. There is outside frosted glass led bulbs and inside frosted glass led bulbs, outside frosted glass is usually used for big size led bulbs, the frost is on the outside surface of the glass globe, the frosted glass is white color, looks noble and much beautiful. However, outside frosted glass led bulb is not smooth, the surface is something like a paper, it is easy to be dirty, that is why each of our thick frosted glass bulb is packed with a clean plastic bag, the plastic bag can only be removed after setting the bulb onto the lamp socket. If there is any dirty on these decorative frosted light bulbs, the bulb looks dirty, and there is shadow when it is lighting on.
