Description

Features:

  1. Special large size, two big glass bulbs in one glass tube, in the center of the this special large size vintage led bulb, there is a long thick strong glass stem, which is the center of the total vintage special led bulb. Though it is large size special vintage led bulb, the lamp base is medium size, which is E27 or E26, of course we can make E40/E39 lamp base.
  2. The glass color is amber gold or black color, actually, we can do any color for the glass according to customer requirement. However, amber gold, clear and black color glass is the three main color for special decorative led lamps.
  3. The lamp base of this special large size vintage led bulb is E27-skirt, means that there is a skirt on the normal E27 base. E27-Skirt lamp base looks a little bigger than normal E27. But why we use E27 Skirt lamp base? Because this special large size decorative vintage led bulb is much heavy, the normal E27 can not stand such heavy weight, the E27 may fall off after some time hanging.

Because it is the glue combine the E27 lamp base and glass bulb together, and it is only the top part of the E27 lamp base has glue with glass bulb, so that these glue must stand for all the weight of the large size special decorative led lamps, if the lamp is too big and heavy, then there is a risk of lamp base falling off.

Comparing to standard E27 lamp base, E27-Skirt has a larger size of the top part of the lamp base, this part is the connection surface with glass bulbs by glue, so E27 Skirt lamp base has an enhanced combination with glass bulb to prevent lamp base falling off problem.

 

More information about E27 skirt (extra E27) as below:

There are standard E27, small size E27-skirt and big size E27-skirt lamp base. We make decision among E27, small E27-Skirt, Big E27-Skirt base on these two factors as below:

1>.Based on size and weight of the lamp, for security considering. Because we have already know the problem of lamp base falling off for extra big special decorative vintage led bulbs.

2>.Based on our production machine, if it is difficult to seal the glass open and set the E27 lamp base, we will use E27-Skirt.

There is 2 size of E27-skirt lamp base, they are small E27-Skirt and Big E27-Skirt. If the diameter of the glass bulb neck is 45-50mm diameter, it is with small E27-Skirt; If the diameter of the neck is 55-60mm, then it is with big size E27-skirt.

E27-Skirt lamp base can allow bigger filament design in the decorative special extra big vintage led bulbs, because the diameter of the glass bulb neck and open is bigger. For normal E27 lamp base, the diameter of the glass bulb open is 40mm maximum, so the filament design can not be bigger than 40mm, otherwise the bigger filament design can not put into the glass bulb from the open of the glass bulb.
