The past solar powered lights I've purchased in the past didn't produce very much light. I recently tried these disk lights, and I'm very surprised on the amount of light they put out! The assembly was very easy. The the pegs that go into the ground are sturdy even for the tougher mud/dirt I have in Texas. They have 4 points on contact under the light so pushing them into the ground they didn't didn't snap. The surface of solar panel is large and holds a charge that lasts well into the night. The lights themselves are a very bright white. They work great highlight my flower beds.
