The Norman Lamps 1630 is an 18W incandescent miniature bulb engineered for precision instrument, medical, and scientific optical applications. Operating at 6.5V with a current draw of 2.75A, this S8-shape incandescent lamp delivers 289 lumens of warm white light at a color temperature of 2700K, with a measured output of 23 MSCP. The clear glass envelope and C-6 filament construction provide consistent, stable illumination suited to the exacting positioning requirements of optical instruments such as spectrophotometers and microscopes. The Double Contact Pre-Focus (P15d) base ensures repeatable, precise filament placement within the optical axis of the instrument each time the lamp is seated. At 2.00 in. in overall length and 1.04 in. in diameter, the S8 incandescent bulb fits within compact instrument housings, and a light center length (LCL) of 1.0 in. facilitates accurate alignment with instrument reflectors and condensers. Rated for 100 life hours of service under design operating conditions, this lamp is a widely recognized trade number replacement compatible with instruments from manufacturers including Bausch and Lomb and American Optical.
