Review Content A great purchase, its powerful. The flash light is worth the price, shines very bright. Wonderful for emergency situations This was bought for my office in case the power goes out so they will still have a source of light in an emergency situation and there is no electricity for an extended period of time. Great device Good, strong and powerful I would buy this product again. Great product for power outage. My husband loves any flashlights.. Briliant idea! Emergency equip. Very bright light Have same flashlight thats probably 6+ years old. After sitting at least a year, to my surprise, lighted up without charging. Great shelf life of battery. Saw light was on sale so bought a 2nd to have in case of power outage. Package was not complete Very irritating that NO A/C Adaptor was included in the box!!!! Totally Anonymous Hand Crank Flashlight I like to do my homework and research a product before I buy it in a store or online. I did a number of GOOGLE searches trying to find information on this flashlight, but came up empty. There was a Gordon product that looked similar, but used 16 LEDs, rather than a single 5 Watt LED used in the Sharper Image unit. Interestingly, the photo of the Sharper Image light shows, what appear to be, multiple LEDs in its reflector. The Sharper Image flashlight came in a plain white unmarked box. There is no manufacturers label on the box, on the unit, nor on the single page Instruction Sheet. The same is true for both the AC and DC adapters. As a result, it is difficult to determine a number of important specifications such as the type of battery used, and its brightness in lumens. The initial AC charge requires 20 hours. A red LED "CHARGE" indicator did turn off when the unit was fully charged. I have not used the light long enough to see how many hours a charge will last. None the less, this unit IS BRIGHT! LOVE LOVE THIS ITEM. TERRIFIC FOR WHEN WE HAVE A POWER OUTAGE. Very bright Very bright light. Not sure how bright because it does not state how many lumens it produces. Bright and Light I keep it by the bed to use when electricity goes out or hear something that needs investigating. Very bright light lights up the area.
