the nightlight provides a yellowish light like on the product photo on Amazon to see what I really like. We use it in the bedroom of our little daughter, which works very well, that they can sleep well, but has the same when she wakes up a good orientation. The lights come on automatically when a non-adjustable limit value is exceeded in brightness in the room. At first I did not bother, since I thought about the power consumption. Have a power consumption meter used and noted with surprise that apparently is the consumption outside the measuring range. Could not be better.
