Its not just the wavelength of light that affects the sleep question. Backlit devices like the iPad are far more likely to affect your sleep than a device like the kindle, which has both lower levels of light and the light is reflected rather than shone directly into your eyes.

When you adjust the backlight down, it's a nice warm off-white. Maybe I have a different model, but I can't see any "white light problem".
