Ideal for a 30 liter, no more

EDIT: after 3 months of use, LEDs have gradually diminished in intensity and 8 LEDS are finalized. I would recommend this product now. The amazon service was outstanding and I could return the product thanks to the guarantee.

Product really great for my tank of 30 liters (nano-cube shrimp).
The lighting is perfect and it is composed of multiple white LED (majority) and blue. 3 colors that can be changed behind the lamp and is ideal for fine days eg to keep a small light in order to observe the content of the aquarium. Lamp fine for a 30 liters, but, I do not know if it will agree. In any case, the direction of light allows it not to be visible on the sides of the lamp.
It is indeed a French socket, consisting of a wired socket charger unit that can be connected to the lamp unit to start up. I have not seen algae disappear or appear.
A good product in all, an excellent value for money!
