Query: Solar lights

First of all, people need to have a realistic attitude about what solar lighting is capable of. They simply do not produce as much light as low voltage and the color is sort of purply blue. That said, with the exception of one light not working out of the box, these lights are great! They need to get direct sunlight to work for several hours. In fact, the ones that get sunlight all day are still on when the sun comes up! The metal construction and glass lense are surprisingly upscale given the price- I like 'em!
