When ultimate color control, a flexible form factor, wireless use, and control are top priorities, the Godox Tube Light is a wise choice. The light has a built in Li-Ion battery that will give you two hours runtime and much more at partial power. Its 29.5" length and 1.9" diameter make mounting it unobtrusively, or even gaffer-taping it an option. It has a wand-like shape, so it just about begs to be handheld.
The Tube light has a wide CCT range of 2700 to 6500K to meet any ambient light challenge, match other fixtures, or just to spark creative expression, while a library of 40 Rosco and Lee filters seals the deal. Yet another plus is the light's RGB mode with Hue, Saturation, and Intensity control giving you access to a myriad of custom colors. Yet another bonus is wireless control with optional gear at distances from 98 to 164' via DMX, a remote control, or a smartphone app backed by 32 channels and 6 groups. The Tube light ships with a power adapter, a DC cable, and a carry bag.
