The colors of the LEDs are not properly mixed. I ordered two of these lamps and in both the same light distribution pattern. In the center of the cone of light can be seen mainly blue components and the blue light cone is surrounded by a red light ring. Thus, plants can grow but equally, the light must be homogeneous mix into a purple. In addition, the lights are far too weak to be able to develop an effect. Well, for 1.99 euros per lamp you can not expect anything! After a complaint has refunded me 60% of the purchase price and postage. Since I had the lights after all, I thought I could at least use it as Moonshine Lighting for Aquarium. So I between glass cover and lights a thin white plastic sheet down to get a scattering effect. This worked quite well and I had a nice night effect in the basin. Unfortunately, the joy was short-lived, as one of the lamps had five weeks after a total failure. So I dismantled the lamp out of curiosity. However, this is not destructively, since everything is glued and pressed. The electronic ballast is necessary, failed because the LEDs themselves to work even when they are powered by universal AC adapter. Addendum of 21:05. Now the second lamp is out. Here you can see the first and last LED (blue) are charred. All other LEDs glow as though to himself, as in the series of LEDs now arrives no or hardly any electricity.
Overall, a faint idea of this Grow Lamp, which gets only two stars because Andoer therefore in advance proportionately rewarded me the purchase price.
