All as in the photo. 5 speeds, 5 brightness levels from the remote. When switching a static color, the brightness is reset, the maximum is set. When switching 1 out of 4 flashing modes, the speed is reset, put on the average. 20 cm about like a volleyball ball (21 like). When switching through the touch, flashing seems at maximum speed by default costs. With the touch just in a circle, each touch on, first colors, then flashing and off.
