Canopy lights, LED or otherwise, come in a wide variety of shapes, sizes, mountings (recessed or surface), brightness, durability, moisture resistance, and of course price. For something simple and inexpensive in or around your home you can check out a Costco or regular hardware store. They usually have one or two interesting items that may satisfy your needs. Otherwise, you need to determine your budget and exactly what you need before going to a lighting store. You can pay anywhere from $40 for a simple fixture to hundreds or thousands of dollars for a lighting system.
