Query: Gamasonic GS-29W Solar- Powered LED Spotlight, White Bulb

It does not stay lite more than 2 hours and the light is very low, even when I place it facing the Sun and move it around to continue receiving the Sun Rays.I had to purchase an electric one.I would like to return it for a refund.Can you please send me a Return Authorization Form? Thank youBest regardsAmado Palavicini
