I use this led over a hangon refugium with chaeto macro algeas. The tank is a nano SPS only. The chaeto grows perfectly

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

Trylly not impressed. Light is not bright. For fish is perfect.
But if you want plant you shoud buy 2-3 for 20 litres tank.

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.

The light functions well but I would need two for my 26l nano. The light is in need of a purple and some blues if it is to look as good as the PC bulb.
If you just have fish then this will be fine. Very bright for it's size.
