I think about the product there is generally not much to say, so I would like to mention a little comparison:
So far I had always been relatively cheap bulbs from Conrad in use, which have been for a short time (2-3 months) given up the ghost. For this reason I have this time tried the product from Osram and already for 5 months without any problems in use. Of the 8 in use pears no break has gone so far.
The luminosity is comparable to the cost of bulbs Conrad, if not a little helper.
In conclusion, a strong buy recommendation.
