I'm looking to get an LED strip that I can connect to my shelving system, above my albinos' tank. I need something that plugs in, and that I will be able to hook up to the shelving unit which is made of rought iron. I have no idea what I am doing. I have been looking on amazon and I see hard wire strips, strips that require transformers or something, battery powered strips, and strips that need to be screwed into wood. Can anyone help me find something that will work for what I need...that is affordable? Thanks.
