1. The advantage of this vintage Led bulb is the coating finishing, it is made by JKD stoving varnish coating, outside sand coating, it looks like white color silkworn cocoon when it is turn off, looks like golden color silkworn cocoon when it is lighting on, both shape of this vintage Led bulb and color looks like silkworm cocoon.
2. Straight filament led inside the vintage led bulb, 4 pieces of 68mm Led filament can make 5W, with 2200K kelvin can reach a lumen of 400lm if the glass is clear. However, this decorative vintage Led bulb is with thick sand coating, it stops more than half of the lumen, that is why white coating vintage Led bulb has a much lower lumen. And this is a kind of decorative Led bulb, if the lumen is too high the design doesn't come out. Our engineer make testing and choosed the best lumen output.
3.The stem of this vintage antique led bulb is made of glass tube, it is thick strong anti-breaking glass stem, the soft flexible Led filament is supported by this glass stem. We did a lot of testing before mass production of this model, there is no breaking of this glass stem. This vintage lamp has been manufacturing for more than 3 years, no breaking complaint at all.
For stem, there are mainly two materials, one is glass, the other one is iron wire. Iron wire is strong enough and has a cheaper cost, that is why most of the cheap or low quality vintage antique bulbs are with iron wire stem; Glass stem is fragile and has an expensive cost, but glass stem is more beautiful, same material as the glass globe, the whole vintage lamp has an unifform style, that is why quality vintage bulbs are with glass stem. Glass stem has two different version, one is glass rod, the order one is glass tube. Glass rod is mainly used for small size vintage bulb, such as G45, A60, T45, C35; while, glass tube stem is mainly used for large size vintage lamp, such as G125, A165, G200, because glass tube stem is much stronger than glass rod stem when it is with larger size.
