Product Description

This part is a 6-volt miniature incandescent lamp used as an indicator or signal light in low-voltage equipment. It provides point-source illumination for status indication or backlighting in compact panels and instrumentation where a small T1-3/4 bulb with a midget groove base is required.

0 1. Overview

The 337 lamp uses incandescent technology with a clear envelope and a C-2R filament arrangement. It is built with a T1 3/4 (RT-1 3/4) bulb shape and a midget grooved lamp base identified as ANSI S5.7s. The lamp operates at 6 volts with a power rating of approximately 1.2 watts and a current of about 0.200 amperes, providing an omnidirectional 360-degree beam pattern. Rated service life is 1000 hours under specified operating conditions. The lens construction is round with a domed top and a clear finish, and the design supports universal operating position. Packaging is available in box format for component supply, and single-contact configuration is specified for the electrical connection interface.
