I purchased 4 packs of these security lights and they work great!  They light up a lot of area and are super bright.  The motion sensor works wonderfully as well.  I placed them on a table on the porch to charge up and later that night they turned on when someone was walking in the street which is about 15 feet away.  I live in Texas where there is a lot of sun so they work great on them days  but on rainy cloudy days they do not work.
