PIAA Foglights
PIAA Foglights
Anyone have PIAA foglights? If you do, do you like them and how much did you spend? Pictures would be great as well if they are HID or not and the bulb frequency.
Thanks

I have PIAA Xtreme White fog/high beams. They are H4 bulbs, they are not HID's. The color temp is 4100k and I believe the HID's are 4350k so they are not quite a perfect match. Much improved over stock though. What is bulb frequency?

The distribution of different light colours in continuous spectrum light sources is measured by its colour temperature in Kelvin. The Kelvin scale of temperature measures from the lowest possible temperature (absolute zero) with the same interval size as the normal Celsius (Centigrade) scale.
Ice melts at 273K and water boils at 373K. When objects are raised to high temperatures they emit light, starting with a dull red (when they are 'red hot') and shifting towards blue as the temperature increases. An ordinary domestic light bulb may emit light with the same spectral distribution as an object at 2800K, tungsten studio lighting as 3200K and normal sunny daylight as around 6000K.
The Kelvin scale defines the colour of a light's output with relationship to the degree of heat applied to produce the specified colour of light.
A tungsten filament light bulb placed on a dimmer illustrates this relationship. As the electrical current is increased, more resistance is created within the filament. This increases the heat of the filament. Decreasing the electrical current lowers the resistance, thus reducing the heat in the filament. When the heat of the filament is low, an amber glow is produced. The filament produces light that is less amber when the heat is increased.
The intensity of a light source does not influence the Kelvin temperature. The Kelvin scale measures the quality of light output and not the quantity of the light output.
