The night lights are extremely energy efficient, because it does not concern halogen bulbs, but LEDs. This LED night lights consume only 0.4 watts. The brightness is optimal for the night. A bright light would interfere with sleep. These ones are just as bright that you can see standing around objects or finds the way to the toilet.
In everyday life with kids the night lights are extremely practical. The children see where they go-out night. We hang these lights, for example in the hallway by the stairs. It gives us parents a feeling of security, because one has somehow always a little afraid that the kids accidentally fall down the stairs at night in the dark times.
What is not quite so good like the flickering light all four lights. It is especially noticeable when you look closely at the lamps or she has in view. In addition, the lights are ugly gray and not white as shown. The actual color looks like that of the old computer screens and is long outdated.
Conclusion: Practical and suitable for everyday use, including unfortunately slight flicker. Price is right.
