  I personally keep them close~ in our lab experience, we uses light pulse to trigger some physiological responses, so i’d avoid that in the middle of the night. besides, the middle of the night is not total darkness, there is always light leaking from street lamp 🙂

  I tend to disagree with Petrina. The light emitted from a normal household light is unlikely to do much in the short-term in terms of waking you up and personally I would rather find the bathroom safely and know where the toilet is! Now, I don’t turn on every light in the house so you could see my house from outer space but enough light to do what I need to do…
