Lights

Six aquarium lights, from a 1.8 W submersible tube to a 72 W planted-tank light, sized by the length of your tank in inches.
Clip-on and extendable lights cover most freshwater tanks. Over a 1 to 5 gallon tank, the 6 W Clip-On light bends on a gooseneck and runs from a 5 V, 2 A USB supply that you provide. On the Extendable LED light, the bracket slides to fit the rim, in sizes for tanks from 6 to 54 in long, and its timer runs 8, 10 or 12 hours a day before repeating.
Two lights follow the sun on their own: the 24/7 Full-Spectrum light and the Planted Aquarium Light switch on at 6 a.m. and off at 10 p.m., with day and night hours you can change. Planted tanks get the most from the Planted light, at PAR 180. For coral, the Dimmable Reef Light adds 12000 K white and 400 nm violet, and inside the tank the Submersible LED tube cycles through 8 color modes.
The 6 aquarium and terrarium lights on this shelf belong to the Pawfly collection.
Also by need: nano tanks, 1 to 5 gallons.
Measure the tank's length, then pick the option whose range covers it. The Extendable LED light comes in sizes from 6 to 10 in up to 48 to 54 in, the Reef light from 12 to 18 in up to 48 to 54 in, and the Planted light for 16 to 22 or 46 to 52 in tanks.
The 24/7 Full-Spectrum and Planted lights do: they switch on at 6 a.m. and off at 10 p.m. and run through day and night on their own. Timers do the job on the Clip-On, Submersible and Reef lights and on the timer versions of the Extendable: pick 8, 10 or 12 hours and the light repeats that window every day.
Red, green and blue, alone or in pairs, plus full light and a slow-flashing full light: 8 modes in all. The first 7 modes dim through 5 levels. Its tube draws 1.8 W, comes in lengths from 7.5 to 23 in, and its timer sets 8, 10 or 12 hours.
