I bought two of these lanterns recently. They are bright as advertised but they are far from military grade construction. They are cheaply made plastic and you must really be careful when closing them as often they remain lit when closed. The ad shows the (strong magnetic base) securing the light to a metallic fixture while they pull it open when in reality the ones i received can barely suspend the lantern without it falling. No way can you open it without it pulling loose. Higher quality lanterns are available at a lower price.
