Everything is in the title: - Of that there is some ambient light, we do not see too much lighting. - It must be well in front of the spot to control. - Then activated by the switch, it returns to demo mode and constantly changes color, it must choose the remote control what you want. If you turned off the spot to the remote control, it turns on again as it was before being extinguished. Cheap, delivered quickly. I am very satisfied for now. Until the technology is still evolving and offers a wider and cheaper choice is a product that satisfies me completely.
