Halogen
Lamp
Applications
Halogen
lamps
are
ideal
for
a
wide
range
of
applications
from
airports
to
TV
studios
as
can
be
seen
from
the
following
list:
Airfields
Radiant
Heating
Department
Stores
Slide
Projectors
Security
Lighting
Vehicle
Lamps
Display
Cases
Theatres
Supermarkets
Shop
Windows
Dentistry
Traffic
Signals
Garden
Lighting
Lighthouses
TV
and
Film
Studios
Operating
Theatres
Dental
spotlights
are
typical
of
optical
devices
and
instruments
that
use
halogen
lamps.
Some
use
low
voltage
lamps
with
smaller
filaments
to
approximate
a
point
source
of
light.
Low
voltage
lamps
have
higher
lamp
efficacy
and
better
beam
control.
However,
low
voltage
lamps
require
a
transformer.
Downlights
often
use
single-ended
capsule
lamps
or
low
voltage
reflectors.
Small
unobtrusive
luminaires
are
possible
because
of
the
compact
lamp
proportions.
See
Figure
8.14.
Downlighting
is
found
in
offices,
stores,
lobbies,
restaurants,
theatres,
hotels
and
homes.
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.
Both these reference systems are used
industry-wide so the customer has a clear
indication of compatibility between
manufacturers products.
Other order codes are similar to
incandescent lamps but the information
sequence changes, e.g. G95/150/ES/230.W is
a 230V 150W HaloGlobe with White bulb and
ES cap.
