Satco Products Halogen Lamps - Manual (Page 4)

Brilliant, White Light:
Halogen lamps deliver a crisp, white light. Not
only is the quantity of the light greater than
a standard incandescent of comparable
wattage, but the quality of the light creates
a higher contrast for reading and other tasks.
This also makes halogen perfect for display,
accent and general lighting.
Color Temperature & Rendering:
Since halogens are incandescent lamps,
their CRI of 100 will render colors accurately and will match the color
temperature of other light sources in the 3000K range.
Long Life:
Standard incandescent lamps and halogen
lamps both use tungsten filaments. However, the
filament in the standard lamp evaporates over
time, causing it to weaken and eventually break.
The gasses inside halogen lamps allow the
evaporated tungsten to find its way back to the filament
and redeposit, ensuring a long life of 2,000 hours
or more.
Lumen Maintenance:
Compared to standard incandescent lamps, halogens offer superior
lumen performance throughout the life of the lamp.
Halogen lamps can be dimmed using a conventional incandescent dimmer. However,
using a dimmer actually has an adverse effect on the lamps.
Standard incandescents benefit from being used with a dimmer due to the reduced
voltage being applied to the filament. Halogen lamp filaments need to be operated
at higher temperatures (250 degrees Celsius or higher) for the lamp to function properly.
when a halogen lamp is used on a dimmer, the filament will not reach this temperature
and the halogen cycle will not work.
Halogen lamps that are
dimmed to low levels for
extended periods of time
will begin to blacken on
the inside wall of the bulb.
This will reduce light output
and life. It is possible to
restore the bulb to a certain
degree of its original state
by running the lamp non-
dimmed every so often.
This allows the halogen
cycle to clean the inside
of the bulb.
Big Benefits
Halogen lamps offer a combination
of benefits that make them an
appealing alternative to standard
incandescents in many applications.
What Is a
Halogen?
Halogens are five non-metallic
elements found in Group 7 of
the periodic table. The term
“halogen” means “salt former”
and compounds containing
halogens are called “salts.”
The halogens are: Fluorine (F),
Chlorine (Cl), Bromine (Br),
Iodine (I) and Astatine (At).
HANDS OFF!
While conventional incandescent
lamps can be handled
with bare hands, halogen
bulbs should not. Since the
quartz envelope, or bulb,
of the lamp reaches high
temperatures, the oils and
salts from skin will deteriorate
and weaken the bulb.
If your hands should come
in contact with the bulb, use
a small amount of rubbing
alcohol and a soft cloth to
clean the lamp. Allow time for
the bulb to dry before using.
