is the difference:
There are several differences between stock halogen bulbs and performance
bulbs. Brightness is the first and foremost difference. The higher the
Kelvin color temperature the whiter light the bulb will produce.
A stock halogen bulb has a color temperature of about 3200 Kelvin performance
bulbs are brighter and are rated at 3800K all the way up to 5000K for
Xenon gas bulbs. It's a great alternative to expensive HID (High Intensity
Discharge) lighting that is difficult to install and requires parts, time
and labor to install.
Halogen lamps in addition to being gas filled, have a gaseous halogen
compound added to the gas fill. The halogen compound constitutes a small
portion of the fill gas and must be accurately controlled. The quantity
used is on the order of 100 parts per million of fill gas and is usually
a bromine compound. Its purpose is to prevent any blackening of the bulb
by returning evaporated tungsten back to the filament through a halogen
cycle. Too little halogen permits blackening of the bulb to occur. Too
much halogen destroys the tungsten filament.
with proper operation of the halogen cycle no blackening occurs, the bulb
can be smaller than what is normally used in regular gas filled lamps.
With smaller envelopes, higher molecular weight inert gasses and higher
fill pressure are practical. Krypton is generally used in automotive halogen
lamps and the fill pressures at room temperature is approximately 5 atmospheres.
Higher Molecular weight gas and higher fill pressure permits operation
of the filament at even higher temperatures than regular gas filled lamps
so that for the same life, halogen lamps have the highest efficiency of
all miniature lamps. The installation of these performance headlight bulbs
is easy. No special wiring or ballast is needed. Just replace the regular
light bulbs with these. It's that Easy!
Xenon filled halogen replacement bulbs utilizes a tinted glass envelope
that actually increases the color temperature of the bulb closer to that
of daylight, thus producing a significantly whiter light beam, resulting
in greatly improved night vision by increasing contrast and providing
better reflective properties. This special process dramatically increases
the whiteness of the light with only a trace of blue hue at the headlight
periphery. The addition of Xenon gas is used to cool the light filament,
allowing the Halogen to process higher light output resulting in a 20-30
percent increase in perceived light.
Despite the blue glass, these light bulbs do not emit a "blue" beam of
light, rather the light is so brilliantly white, that it is perceived
as "bluish-white" when compared to regular halogen headlights.
Do I need anything else besides the bulbs?
Again, the installation of these performance headlight bulbs is easy.
No special wiring or ballast is needed. Just replace the regular light
bulbs with these. It's that Easy!
long will performance headlight bulbs last?
Performance bulbs tend to have the same life as stock halogens and can
give years of great service. Several things can have an effect on the
lifespan of a bulb. The life of a filament is voltage sensitive. A stable
electrical system in your vehicle will help to increase the lifespan of
your halogen bulbs as well as the condition of the headlight units themselves.
When installing your bulbs please remember to take care not to touch the
glass portions of the bulbs.
