So I have the same times bought nine pieces and screwed at a distance of 45cm to 230 fairy lights. The results speak for themselves really. Since the infrared receiver can not be sooo sensitive to the remote control, interesting effects by single switching of lights produce. The brightness of a party room is sufficient. This gets you 100% no white light is really to get over with the price. These lamps are used for effect and party lights. Great Thing ...
