Description

1. Large candle shape soft Led vintage light bulb, with a long glass tail. 450mm length soft led filament forms a dual spiral filament design, totally 8 circles in the soft spiral led filament design.
2. Black color glass but transparent, just like the sun glass with little black color. The part close to the lamp base part is clear, we also can make it black color, it can be made according to customer requirement. Black color glass is very nice beautiful and noble, customer like it very much. But transparent black glass color will stop about half of the light output, for example, 4W 2200K bulb clear glass bulb is 180lm, then black glass bulb is only about 90lm, black color absorb lights. That is why we can see the filament design clearly when it is turning on.
