TUNGSTEN HALOGEN LAMPS
Tungsten halogen lamps use several different forms of order code.
ANSI Specification
This is a three letter random code from American National Standards Institute e.g. EZX. It
describes the lamp exactly. If a characteristic of the lamp is significantly changed, such as beam
angle or wattage, it is a new lamp and is given a different ANSI code.
LIF Reference
This is a single letter followed by numbers from Lighting Industry Federation e.g.
-
Al/ projector lamps
-
K/ floodlighting lamps
-
T/ theatre lamps
-
M/ miscellaneous lamps
It describes the lamp exactly. If a
characteristic of the lamp is significantly changed, such as beam angle or wattage, it is a new
lamp and is given a different LIF code.
The LIF is the (British) Lighting Industry Federation.
