The Norman Lamps 2233 is an incandescent S8 miniature bulb engineered for aircraft cabin lighting and other aviation low-voltage applications operating on 28V electrical systems. Built to the widely recognized ANSI 2233 standard, this bulb is cross-referenced under military specifications MS35478-2233 and M6363/12-8, confirming its suitability for demanding aerospace and aviation environments. It operates at 28V with a current draw of 0.77A and a wattage of 21.56W, delivering a light output of 21 mean spherical candlepower (MSCP) from a clear glass S8 envelope approximately 2.00 inches in length and 1.00 inch in diameter. The gas-filled construction incorporates a CC-8I coiled-coil filament with internal lead support for added vibration resistance, a characteristic well-suited to the mechanical stresses encountered in aircraft interiors. The single contact bayonet base (BA15S) provides a secure, tool-free installation and positive electrical contact in panel and fixture sockets designed for this base type. Rated for an average life of 2000 hours, the 2233 is compatible with standard 24V to 28V aircraft cabin lighting circuits and serves as a direct replacement in a wide range of commercial and general aviation interior lighting fixtures. As an incandescent lamp, it is inherently dimmable and produces a warm, continuous-spectrum light output. This bulb is sold individually and is also available by the full case of 10 units.
