This frog is a nice size, all plastic construction but looks almost like stained glass. There is a rechargeable AA battery included/installed, and the solar panel sits in the middle of the frog's back - it's roughly 2x3 inches. There's a weatherproof on/off switch by the solar panel. The light itself is inside of the frog - it must be an LED or something similar as it's a very white light when it comes on. As for the amount of light it emits - not too much - more of a nice glow throughout the body of the frog. We were originally thinking of putting it in our landscaping by our front entry, but the entryway outside lights are much brighter than this frog, so you wouldn't really see it glowing. We've now put it on our deck / patio where there's less light at night - a very cool glow now visible.
