The USB Touchlight is a small pendant light that is powered by any USB power source, even a battery pack. Turn the light on/off and toggle it through three lighting levels by pressing on the patent-pending lens. You can hang it anywhere and use it indoors or outdoors. The light is 114-132 lumens at 350 mA, and the color temp is “neutral white” at 3,700-5,000K. You’ll need to provide your own power source. The USB Touchlight is $35 at Voltaic.
