This incandescent lamp includes an envelope, a fine-wire filament within the envelope, and lead wires supported on the envelope and having inner portions within the envelope connected to opposite ends of the filament. The filament is rendered high resistant to damage from vibration and shock by: (a) stiffening the filament with a support wire connected between the envelope and an intermediate point on the filament and (b) constructing the inner lead-wire portions in such a manner that the natural frequency of the filament is between 1. 7 and 2. 2 times the natural frequency of each inner lead-wire portion.
