Hello Tim - welcome to the forum!
Not sure exactly what you want to do since the iPad can be 'read' already w/ the lamps off, but is quite bright! You might want to go to Settings > General > Accessibility > Invert Colors - kind of a weird look w/ colors, BUT on a black & white screen, such as the Kindle app, the background turns black and the letters white - might give it a try in a closet - let us know if that's what you're after?

Hi Dave
sorry I did not know that I will give it a try. Thank you
