Review on 🔆 Litever Under Cabinet Light, 6 PCS 20 Inches Flexible LED Strips with Power Adapter, 24W, 1800 Lumen, Daylight 5000K. Ideal for Kitchen Cabinets, Counters, Under Shelf, Closets (6 Strip Set - Daylight 5000K) by Nicole Thompson

These are incredibly bright for under cupboard or shelf lighting and come with small sticky fasteners (top right of large photo) to secure cords in place or to roll up excess for stashing and to hide. The more expensive ones I bought from Home Depot didn't include these gizmos and weren't as sticky so I had to use black tape which peels off after a few months. Also add other bits to secure the cord from the outlet to the baseboard or elsewhere. I also appreciate that all the wiring is black so it's easier to hide along the black legs of my showcases. Note: They are supplied on a roll. Although they have all sorts of small installation pieces, I expected to just glue straight strips like in the photo. I unwound them to straighten them and no problem as the pieces are not that long.
