Below you'll find a few pages from a 1976 CRAMER catalog (now-defunct industrial electronics distributor) giving basic specs on standard miniature lamps and cartridge lamps. The data is in a simple tabular form, rather than exhaustive design data, more than adequate for identification and cross-references or replacement purposes. The 1976 prices are for amusement purposes only.

• Table of standard miniature lamps, in Lamp # order. Bulb and base data is on next page.
• Base style and bulb-shape keys; miniature and subminiature lamps; bi-pin lamps; line-voltage lamps; neon glow lamps; Mil Spec "MS" cross-reference table.
• Mini and submini bi-pin lamps; "peanut" lamps.
• Cartridge lamps.

• Please note that all of the mages files above are JPEG files of 200 dpi resolution; the file sizes are 1 to 2 megabytes, for which I apologize; however, once data is lost it's gone forever, and bandwidth increases all the time.
