1. A165 size big size decorative led bulb has a size of diameter165mm, 300mm length, with medium size of lamp base of E26/E27/B22, also can be with big size lamp base of E40/E39. The whole glass bulb is with silver spots plating, which is brush shape, the silver planting is almost full of the glass, in order to have the lighting effect, when it is lighting on, the light is coming out from the pore of the silver plating, we can see the dual spiral soft led filament.

2. This decorative big size flexible soft led lamp has a dual spiral filament. There is single spiral filament and dual spiral filament, the difference is as below:

1>. Single spiral filament is more normal, it was used a lot for incandescent Edison bulbs, for example st64, G95 spiral filament incandescent Edison bulb. Small size light bulb can not be with dual spiral filament, can only be with single spiral filament. For single spiral, the filament is starting from the bottom of the stem(bulb) and ends at the top of the stem(bulb), the filament is hovering around the stem.

2>. Dual spiral filament is mostly for big size bulb, for example G125, A165. The filament starts from the bottom of the stem(bulb), hovers around the stem to the top of the stem, and then hovers to the bottom of the stem(bulb), that is to say the filament stars from the bottom of the stem and ends on the bottom of stem too.

Some people like single spiral filament, because it is traditional; some people like dual spiral, because it is new.
