Beautiful light, but the life?

Three of these LED bulbs I bought in Janaur 2014 amazon. Today, on 31.10.2014, the first breathed with a crackling their minds. Now it flashes only and should be discarded. After an estimated 600 hours of operation which is very unfortunate, especially since the light of this very pleasant warm white LED is in the range of traditional bulbs. When a manufacturer's specification of Ø35000 hours 600 hours life time only just under 2% :-(
Hopefully, the other two hold much longer.

After I but the supplier Fa. Leuchtwerk, my sorrow "complained," I immediately got offered a free replacement! I think this is not for granted. Well, on Saturday to 1:11. and criticized on Tuesday the 4:11. already delivered. Excellent!

After my research, it is - at least by way of example - repeatedly before, that LED bulbs give up long before reaching the desired operating time. So you will have to live a little longer ...
