GE Lamps manual Typical Working Distance, Light Centre Length LCL, Maximum Overall Length MOL

Typical Working Distance

For Multi-Mirror®and other reflector lamps and MARC™ lamps, the Working Distance shown is the distance from the front surface of the reflector rim to the film plane, in the optical system for which the lamp was first designed. In most cases, it provides a uniform plane of light for the intended aperture.

Light Centre Length (LCL)

This dimension defines the location of the filament in relation to the lamp base. It is measured from the geometric centre of the filament to a specified point on, or plane through, the base. Light Centre Length is subject to manufacturing tolerances.

Maximum Overall Length (MOL)

This dimension includes the lamp bulb and all rigid parts of the base. Since

the listed lengths include maximum tolerances, actual lamps are generally slightly shorter.
