The next party may

Video at Amazon.com See the bulb is already quite large. About 15 cm long and at the thickest part 8cm wide. The best is always a very simple rope swing (large version), because the effect of the lamp must not be lost by a lampshade yes. So the bottom third must hang freely and definitely best relatively high. For the most effect takes place at the (dance) -floor. Top you can see only a few weak rays. See my video.
The bulb turns into itself. The revolution is mediocre fast. Perfect for Disco, Party, Karaoke, ... As a relaxation Lamp unfortunately moves a tick too fast. The engine is extremely quiet, only if you go with the ear directly to the lamp, you can hear the whir.
The lamp is probably entirely of plastic (up to screw holder, etc.), so it can also be convenient times taken to the next party.
