I really wanted to like these. I carefully positioned them toward the sun, waited a few days for them to fully charge, but they are pitiful. I ordered three sets, out of the six total purchased 3 never lit, of the 3 that did work, the light they emit is inadequate and nothing even close to resembling a spot light. More like a normal solar pathway light. I will be returning these. It's a shame, had they worked it would have solved a landscaping dilemma for me in an environmentally friendly way.
Just so you know, these were used in Florida, the sunshine state. Heavenly only knows what would happen in a less sunny environment. Save you time, money and energy, these do not work.
