Backlight Level Default Value (NVRAM)

Hi,

I'm trying to figure out how to setup a default backlight value for my Macbook Pro. Sometimes I turn it off during the night with a really low backlight level and when I try to login during the morning it renders completely impossible to see the screen and move the cursor to my user. I would like to know if it is possible to set a fixed value every time the computer boots up, as I can't use the keys to control the backlight level before login with my user.

When I issue in terminal the command nvram backlight-level, the value is %ff%03 (65283 in DEC?)

I don't know if I could setup a fixed value here or the range of valid ones, Any help?

Thanks so much!
