Satco Products Halogen Lamps User Manual

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.

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.

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.

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).

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.
