Battery effect of backlight keyboard

I am just wondering what the effect of the backlight on the keyboard is on the battery. It must be minimal becase it's such a small light, and thus power impact, but is there any at all that is noticeable?

Minimal is a relative term. The battery time remaining on my gauge fluctuates by a couple of hours when i mess with the keyboard brightness. i think its not very accurate.

It is very small in comparison with almost any other process initiated by the user.
