This P120 P7RGB PRO Waterproof RGB Tube Light with Built-In Battery from DigitalFoto Solution is a serious, multi-featured LED light fixture with a 42" form factor ideal for holding by hand. One of its attention-grabbing features is its IP68 waterproof rating that allows it to be submerged to 16.4' but it also has major color control options. In "normal" mode the CCT temperature is variable from 3000 to 6000K. It also has an RBG mode that gives you access to 36,000 custom colors. It's dimmable from 5 to 100% and while you can make adjustments to color and light intensity locally on the fixture but you can also make them via a free app or with the included remote control. The remote also allows you to control four modes including Lightning, Gradient, Progressive, and Police Car. The 120 P7RGB PRO runs on an integrated 7.3V / 10400 mAh battery that will give you up to five hours of runtime.
