Pretty good but not the best.

BUT - there are some criticisms.

1) There is no harmonious light, just colored light. Green, Blue, Bright (which, however, more greenish u. Looks bluish.)

2.) The red light stands out insofar as all other colors the room well to medium brighten BUT the red actually has no real luminosity - makes sense in some areas, but not in order to keep track in the dark.

3.) The color changing mode 2 problem comes to light - it change all the colors through but then when red appears it is quite dark.
In general, a color that not one of them fits.

The advantage of this - who is all too bright can select red. Where would we be the next point.
And you can select different colors can (which is not really well) and this "fixed" lights.

The flat construction has optical advantages but when you remove the socket you could tell that it is a bit difficult.
It may be that here but are the ghosts in the end it is my impression. The price is okay - here you can not complain too large.
