I find the LED bulbs from Iwy Light just great! They can be rotated without much effort into the socket and away you go. It makes a lot of fun to play with the lights and the colors to change again and again. The Led lights create a very cozy atmosphere. Not even children find pleasure, because with Led lighting of Iwy Light succeed within a very short time to create the right atmosphere for a circus or a magic show. Then it's spot on and the show begins. Also for the children's disco and a pleasant atmosphere at Christmas are the colorful lights good geeignet.Das great thing is also that the free "Mi Light" - App runs even with the current Apple IOS version. Thus, it is perfectly possible to use the iPhone for regulating the light. With the supplied remote control but it works very well.
