Lume cube original. This is not the 2.0. Excellent condition. Will come with micro usb charging cable 10 manual brightness settings, increasing in increments of 1500 lumens (yeah I don’t know what that equates to either). 6000K light temperature. Waterproof to 30m, or 100ft. Optical slave flash (meaning it will fire when it detects another flash). Constant model (or ‘video’) light. Standard threaded tripod screw at the bottom. Charges via micro USB. There are two buttons on the Cube itself, which control its operation. One of the buttons turns the light on, and gradually increases the brightness. The other button turns the Cube off.
