The Norman Lamps 35A-1 is a T2 incandescent miniature bulb engineered for reliable indicator and pilot light service in telephone switching equipment, control panels, switchboards, and instrument arrays. Operating at 35V with a current draw of 0.04A, this lamp draws 1.4 watts and delivers 1,000 end foot candles of focused illumination, making it well suited to panel and status indicator duties that require consistent, visible output at low power.

The compact tubular T2 envelope measures 1.69 inches in length and 0.26 inches in diameter, allowing this incandescent miniature to fit within the tight clearances common to telephone-style slide-base sockets and densely populated equipment panels. The ANSI Number 1 Slide base provides secure, tool-free insertion with positive electrical contact in compatible slide sockets. The C-2F filament construction supports dimming, giving system designers the flexibility to adjust brightness where circuit conditions allow.

Rated for an average life of 7,500 hours, the 35A-1 incandescent miniature offers dependable long-term service as both an original installation lamp and a direct replacement for equipment specifying this voltage, current, and base configuration. Each lamp is sold individually and is available by the case in quantities of 10.
