This light emits a low light even when switched off. it keeps us awake. We contacted the company and they asked us to photograph the light. Clearly that's impossible because the room is too dark for a natural photo and then if the flash goes off it wipes out the low light. it has thrown our sleep cycle off completely. We will be returning them even though everything else about them is great. Why can't they turn off completely. the blue light needs to go.
