Miniature Incandescent

The term “miniature light bulbs” covers a wide range of mostly low volt incandescent bulb types with unique shapes, bases and filament configurations. Most miniature bulbs were originally manufactured for a specific application or type of equipment with precise lighting requirements. Automotive, aircraft, instrument, indicator, signal and medical applications are among the most common uses for miniature light bulbs.

Miniature bulbs usually operate at 28 volts or less often with amperage under 1.0A. To miniaturize the tungsten filaments, the manufacturer coils the filament wire, effectively shortening the length so it will fit in smaller bulb shapes. LED technology, with its small form factor, long life and high efficiency, is a now an alternative for replacing common miniature bulbs.
