The is managed in September 2013 bulb went today broken however.
Later I'll even contact by phone to the customer of Philips. The Support page of the written complaint does not find the LED bulb.
The value for money I would accordingly assessed as not good. If you set the cost in relation to the energy savings, the value for money does not fit.
Therefore, only the 3 stars.
edit: just talked to the Philips Support. Very nice.
This has queried the flash duration, shift times and few other things.
Now I should get a new bulb in the next 2 weeks.
edit: The new pear was then delivered quickly. To date, it is still running. :)
