The difference of HID bulb & halogen bulb

HID & Halogen

 

    The illumination color of light generated by HID is similar to sunlight and does not cause any stress or harm to the eyes.
    Visibility at night has been dramatically improved allowing drivers to see farther ahead and with significantly greater clarity. This reduces bodily fatigue and allows the driver to see the road surface even in a inclement weather, contributing to greater driving safety. Half of all nighttime automobile accidents are caused by inadequate lighting systems, and as the driver gets older, he or she needs approximately 10 times the amount of lighting as used by younger drivers.

    HID lamps from Yifano can replace halogen lamps on any car model, even North America specs such as 9004,9005,9006,9007 as well as general purpose models H1,H3,H4 and H7.
    With color temperatures ranging from 4,200K to 12,000K, Yifano provides a wide selection of lighting colors, satisfying the diverse needs of its customers.

 

    Many people believe that the higher the colour temperature the brighter the lamp. This is totally wrong. The colour temperature is purely a scale to measure the colour of the light output. It is a reference purely for colour and could equally be called White , Green or Blue. The reality is the higher up the scale the lamps are the less bright they become. 4100K lamps are approx 20% brighter (measured in Lumens not degrees K) than the 6000K.

Degrees K = ONLY COLOUR
Lumen= BRIGHTNESS
