The S14S base comprises of an oval connector near each end of a tubular lamp. The connectors are known as ‘oval peg’ caps, and measure 14mm in height. The tubular lamps, which are usually incandescent, are used for architectural and display applications. Because the two caps are fixed to the face of the tube itself they are concealed once the lamp is fitted, enabling a particularly neat and seamless installation.
