Bases provide electrical contact to the lamp and, in most cases, also
support the lamp in the fixture. For miniature and subminiature lamps,
bayonet or wedge base types are generally preferred over screw types when
vibration is present. In addition, wedge bases reduce socket size and
complexity. Flanged or collared types are usually associated with requirements
for filament location.

Bases provide electrical contact to the lamp. The most common bases for
sealed beam lamps are the screw terminal and contact lug types. Other
types are also available, as illustrated.

INTRODUCTION
GE MINIATURE AND SEALED BEAM PRODUCT
ORDERING INFORMATION
GE Miniature and Sealed Beam Lamps are designed for those applications
requiring specific bulb size, base, and voltage. These lamps are operated on
vehicles (cars, trucks, boats, aircraft, tractors) or in special applications utilizing
low voltage sources. Most lamps are designated by common ANSI (American
National Standards Institute) lamp numbers and lamps in this section are
arranged in numerical order. To assist you in identifying lamps, drawings (not
to scale) are provided, along with descriptions of bulb and base sizes.
Specific market segments covered in this section are products used in:
Aircraft
Emergency Building Lighting
Marine
Automotive
Flashlight/Hand Lanterns
Medical/Instruments
Agriculture
Garden/Outdoor
Telephone
CIM/Tractor
Indicator
Toys/Entertainment
For additional specifications refer to Miniature and Sealed Beam Catalog
#20699 obtained through your GE Sales Office. Automotive Selection
Guide
#16153 also available.
FINDING AND ORDERING A LAMP
Most Miniature Lamps have a number on the base or bulb. Generally
it will match the lamp number in this catalog, which is sorted in numeric
order (prefixes last). The catalog is divided into Miniature and Sealed
Beam sections. Sealed Beam lamps start on page 7-15. Often the first
prefix is another lamp manufacturers identification and can be ignored.
You can verify the lamp using the drawings provided. Order codes for
Blister, Unit, and Bulk Pack for OEMs are provided.
FORMULAS
The following are commonly used formulas to assist any calculations you
may need. For further information, contact your GE Lamp Representative.
Watts = Volts x Amps
Lumens = 12.57 x Mean Spherical Candlepower
Kelvin = Celsius + 273
Footcandles = Candlepower/Distance squared
Hot Resistance (Ohms) = Volts/Amps
(miniature lamps only)

Miniature and Sealed Beam.
Order Code:
Use this code when ordering
to ensure that you receive the
exact product you require.
Primary Application:
Current uses of the lamp in general. Lamps are
used in other applications than listed.
Bulb:
The prefix letter describes the shape and the
number is the approximate bulb diameter.
GE Lamp No.:
In nearly all cases lamps are marked with a General Electric Trade Number
recorded with the ANSI. See glossary of prefixes and suffixes above.
Volts:
Voltage at which the lamp is designed
to provide the amperes, candlepower,
and laboratory life characteristics.
MOL:
In inches from the top of the bulb to the
bottom of the base.
