I know other people here read in the dark at between 5 and 7--not sure if I have bad eyes or the light is a little different on my reader.
There's a difference in the requirement for lighting depending on age. From this site:

“Research shows that a 60-year-old needs twice as much light as a 30-year-old. Most of the commonly found lighting guidelines are written with the 30-year-old user in mind,” Eusterbrock explains."
