Don't be fooled by the pictures. There is only one source of light and it is a dim rope light that you see in picture 3. The mirror does not have its own light but the backlight is the light that you see through the transparent part of the mirror. All to say that this neither is going to replace a vanity light nor give you enough light for makeup or shaving. 
Other than that it looks cool and is a good addition if you have other source of light shining at you.
