What data is required to identify a CCFL lamp?

[Ivan75]

I know that the length and diameter need to be correct. Dose a ccfl have a voltage ratting? Does it matter which end is wired to the output or return lines? Are there other things to consider when finding a replacement lamp?

There have been reports of using a replacement CCFL that had a different color spectrum. The result was a tinted band across the screen. I don't have any idea how you would determine the spectrum of the original.

Happened to me once (i saw it from a monitor repaired by someone else).Since there was a set of 2 new ccfls, the guy installed one new on top and one new on the bottom.Screen was colored evenly after that (yet, the colors were different a little bit than with the original lamps)

The only way to tell the color temperature of the original CCFL is to power a functioning one up on an external inverter.

I know I can identify a 3000K, 4100K, 5000K, and 7000K beyond that visually I'd be stumped.

5000K is a neutral white color 7000K is still white but with a bluish tint and the further you go up in kelvin the bluer the light gets.

Thanks for your replies. Is there a voltage ratting for the lamps that I need to be concerned about?
