Tubular LED lamps to replace old fluorescent tubes
These tubular light bulbs by zangra have an S14d base. zangra designed this model based on the historic Linestra linear lamp from the 1930s. zangra has replaced the Linestra incandescent lamp with the latest LED technology, while retaining the charm of yesteryear. These LED bulbs are available in two sizes - 30 cm and 50 cm - and in two finishes: opal or clear glass.

What is the difference between a S14s and S14d lamp holder for stick light bulbs?

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.
