+++ +++ UPDATE
Well and have a great 5 star Rezesion changes into thin air :-(
After one of the lamps was reported in November with stroboscopic flash as a defect, it was replaced promptly by a very friendly customer support.
The week before last, it has then another caught with the same symptoms.
Now I would have to leave again to the friendly and generous customer support but was unfortunately left.
One can only be reached by mail Contact this unfortunately.
This naturally brings nothing if no one logs on my request.
I then still a precaution forwarded another email, unfortunately without success.
No telephone hotline and on the site itself, there is also no phone number.
The supplier turns well on mute.
If you read the Rezesionen here, he must have a general problem.
This investment has definitely not profitable. Too bad, because this bulb with the light output as described actually exactly the solution was that I was looking for.
