1. This is a large tube frosted white color led bulb, mainly for lighting decoration. The size is diameter 125 and 170mm length, large tube shape, also looks like a big bottle. Inside the frosted glass globe, there is 6pcs 68mm sapphire substrate filament led, one piece 68mm length filament led is 1W rated, so this frosted glass led bulb is 6W rated, we can do it 7W at maximum. Because it is white color frosted glass, so we can not see the filament led inside, even when it is lighting on. If we make the frosted layer a little thinner, we can see the filament a little inside the frosted glass bulb.
2. About frosted glass led bulb, there is several situations as below:
1>. There is thick frosted glass and thin frosted glass. For thin frosted, the glass is white grey color, a little white but transparent, so it looks a little dark, that is why we call it white grey color, we can see the filament led inside the frosted glass led bulb clearly. For thick frosted glass it is totally white color, the glass is opaque, we can not see the led filament inside the frosted glass bulb. However, some times we can see the lighting source inside the frosted glass bulb when it is lighting on. Thick frosted led light bulb looks like opal glass bulb, but it is not smooth, opal glass bulb is much smooth, like a mirror, because the glass bulb has to be scratched with it is going with frosted processing.
2>. There is glass bulb inside frosted and outside frosted. For small size frosted light bulbs, usually it is inside frosted, such as C35, A19, ST64. Inside frosted is for a bulb that is smaller than G95, outside frosted is for a bulb bigger than G95, such as G125, G150, A165 and so on.
