I love rechargeable lights and practically live with them. I enjoy the atmosphere they create and the soft peripheral lighting. This set of 4 is fairly priced, if not a tiny bit expensive. However, because they come with magnets and all the equipment to place them on the wall—potentially on top of art—I can overlook this detail.That said, the overall quality doesn't quite fit expensive wall art. The outer casing is plastic with an obvious and visible joint connection of the two parts. If you’re looking to use these for an art piece that costs thousands, they might not be suitable. They are "cheap" and will do the job over a poster, under a table, or even on a metallic hood extractor because they are very versatile.The remote control is relatively well-made, and fun fact: it also turns on another bulb I have that needs this type of control, which is convenient. It requires 2 AAA batteries, which are provided.I am beyond pleased with these for the purpose I got them. However, if you're looking to illuminate a very expensive art piece, they might not be the best choice.
