HID Color Temperature
I'm looking to buy some HID lights and the two different colors are 4250k or 5400. Does anyone know what difference the color would make?

Took a second to find a chart that trys to show what is going on :
http://en.wikipedia.org/wiki/Color_temperature
The actual white appearance of a bulb is best around the 4000 to 5000 K range. Above 5000 K, and the light output will start to look blue to the human eye.
Given those choices listed, the 4250 K bulb will look white, while the 5400K bulb will look more of a blueish-white to the human eye, but should have better illumination on the ground.
Comes down to, do you care what people think. The 5400K bulb will look closer to a knock off HID blue bulb when viewed approaching. The 4250K bulb will have the slight blue tint of a HID when viewed approaching, and the light on the ground will still look closer to white.
I know it is not much help, but pure performance wise the 5400K should be better, I personally don't care for how they look when viewed approaching ( again that blue want to be HID look to it ), so I would go with the 4250 color temperature bulb. As a ref, I have been told that color corrected FL bulbs are 3500K ( SP35 ) and daylight, at noon, is 4800 K. This is a bit off the wiki posting, so take it with a grain of salt.
