These clip on lights came with my tank kit, but there are tons of lighting strips online. Just make sure to get water proof ones
If it is a planted tank, you could go with a Nicrew, Beamworks, or a Finnex, but there are also clip-ons!
Now that I have had the clip on, I will always. So much easier to see when cleaning because the light isn't taken off the tank! Up to you, but that's my 2 cents
My tank is Marineland and it works well but I'm not sure of anything sold separately.... After looking on Amazon, this it the only "aquarium" light, but you can find LED strip lights all day. Some can be submerged in aquariums or suction cupped to the walls. If I were doing it, I would get something like the second link... https://www.amazon.com/gp/aw/d/B00N...=8-11&keywords=aquarium+light+clip&th=1&psc=1 https://www.amazon.com/gp/aw/d/B075...ght+strips&dpPl=1&dpID=51uNn0nU89L&ref=plSrch
any brand is fine probably, but waterproof and maybe fishsafe (it only gets water dripped on it or falls in the water sometimes. unless it is made from cyanide, it should be just fine)
The second one was just a light strip. On closer examination, it has no white light setting just red, green, blue and maybe combo of those, but no clips. It has adhesive strips but they are almost certainly not Aquarium safe. So clips could be purchased or made. But it does not seem to come with any.
Hang it is always a good method. I would suggest going with lights like kessil, since they give a nice ripple effect which looks amazing for hoodless aquariums.
