I purchased these (the 1.0 w) to provide accent lighting for a church service (specifically to add light underneath a glass bowl serving as a baptismal font. The size, ease of use, and spare remote got me thinking very quickly about where else I could add splashes of color, and the basic palette is broad enough to make that very easy.That said, if you're thinking along the same lines you probably want to buy the highest watt version available. They're dimmable, but even at the highest setting they're not very bright (at least in a large, well-lit sanctuary), so the color washes out quickly. On the other hand, in lower light settings (evening service) and where the light is somewhat contained (I put one in a clay jar) they are excellent. I haven't used the adhesive yet, and may never because I like being able to move them around. I also haven't had them long enough to comment on battery usage. For now, though, I'm very pleased with them. Good value in a simple but well-done product.
