But…
Due to bulb limitations this isn’t even suitable for medium-sized tanks, unless you want dim lighting, as for keeping catfish.
For maximum efficiency you’ll need an open-topped tank and, at the time of writing, the Original Tropical pink tube is the only spectral option available.
The tank will need to be fairly narrow front to back too, like under 30cm/12", to get a decent light spread.
The verdict
A simple light, easily fit for purpose. It’s versatile, safe and eminently suitable for small open-topped aquariums or refugiums. The pink tube enhances fish colours too.
