S14s 100cm stick bulb - ribbed glass

The small rectangular lamp holders in which the tubular lamps are integrated are available in two different versions: the S14s model and the S14d model.
The 30 cm and 50 cm stick light bulbs offered by zangra have a single base (a pin). The 1-metre stick light bulbs have two bases (two pins).
For 30 cm and 50 cm stick light bulb, you need a single S14d lamp holder. 1-metre linear light bulb have two pins, so you need two S14s lamp holders.

The lamp holders are usually made of plastic or metal, zangra has designed a very aesthetic version in white and black porcelain.
See here the collection of zangra stick lamps with the corresponding lamp holders.
