A hhandle with integrated light stand mount is also included. Power-up the mobile ringlight with its AC cord or use the included, rechargeable Li-ion battery for wireless freedom. Best of all, this ringlight uses a bi-color design allowing you to control its color temperature (warmth and coolness of the light) with the turn of a dial.
