Neewer RGB61 eyepiece This lens is an uncommonlyThe Neewer RGB61 is a palm sized, battery powered RGB LED light that you can use as a regular little accent light with adjustable colour temperature, or switch it into any one of the "scene modes" for effects like "cop car" and "TV". Many of the effects are slight variations at best (pretty sure "party" and "fireworks" are the same) but who knows, they might come in handy someday. In excellent condition, with diffuser and USB charging cable.
