two of these does the job well in my 18 liters nano

good light, for fish, it is perfect.

très bien pour des poissons, éclairage idéal pour un petit aqua. super aussi pour un autre usage perso en lampe d'ambiance variable.

Esta es una forfa econimica de dar un punto de luz de bajo consumo y con un diseño bonito, yo lo he usado para el refugio de algas del sump.

Good light, the dim is excellent.
On point, the mark is in the front of the base which is not very beautiful.
