no motor noise

I had in front of a different model, which had but given up the ghost after 10 minutes. But these, I was still remembered that the engine noise was quite loud. This, however here is pretty quiet.
As with all these lights you can unfortunately not set a rotation speed. It would be nice if you perhaps can rotate more slowly or perhaps even could completely stop. In small rooms, it can happen that is quite possible that you will be seasick. Especially after a few glasses too much ;-)
