AquaLighter Nano is an LED light designed for aquariums up to 25 l. According to the description, its output and spectrum are enough for the most common undemanding aquarium plants. The colour temperature matches daylight, so the tank looks natural and the colours of fish and plants appear bright. It uses ultra-bright OSRAM Duris E5 Cool White LEDs at 6500 K, powered by a constant-current driver. The clip allows mounting on tanks with glass up to 6 mm thick. The housing is black.

Which plants it suits
The manufacturer explicitly mentions undemanding plants. Under this kind of light, anubias, cryptocorynes, Java moss, Java fern, vallisneria and floating plants usually do well. Demanding red-leaved plants and carpeting plants generally need brighter light and CO₂. If you do not want live plants, artificial ones work too, such as CROCI Replica Anubias.
How many hours of light
Most aquariums need 8–10 hours of light a day. Too long a photoperiod encourages algae, too short slows plant growth. Plugging the light into a socket timer keeps the schedule steady.
Which tank
The light suits small tanks such as the Priroda 22 l aquarium; just check that the glass is no thicker than 6 mm. If you would rather have a ready kit with light and filter, see the Priroda Mini-cube 9.5 l kit.
Other nano tank equipment
Besides light, a small tropical tank needs a heater — the same brand makes the AquaLighter aHEATER MINI for tanks up to 15 l — and a filter sized for the volume. The full list is in aquarium for beginners: what to buy and how to set it up.
Light and algae
If green film appears on the glass and decor, shorten the photoperiod, keep the tank out of direct sun, avoid overfeeding and change water regularly. Bright light without plants to use up nutrients almost always leads to algae.
Installation
Fit the clip onto the edge of the glass and make sure the light sits securely without touching the water. Route the cable with a loop hanging below the socket so water cannot run along it. Unplug the light before servicing the tank.
Care
Wipe the light now and then with a dry or slightly damp cloth to remove dust and limescale, as dirt reduces brightness. Do not use abrasives.
Who it suits
The AquaLighter Nano suits owners of nano tanks up to 25 l with undemanding plants who want a compact light with natural daylight. Other equipment is in the fish equipment section.
Verdict
The AquaLighter Nano is a compact LED light for tanks up to 25 l with OSRAM 6500 K LEDs, a constant-current driver and a clip for glass up to 6 mm, designed for undemanding plants. The downsides are that the description gives no power, light output or dimensions, no dimming or modes are mentioned, and demanding plants may not get enough light.
