One was broken after a short time

Have these LEDs must order 3x. For the first order two of the three pears were cold white.
In the second order, I just got my lights again returned sent
(Shipping ran through Amazon).
In the third delivery two of the three pears were warm white. Together three warm white LEDs: Well
and the cold white three well zurückgeschickt.Waren everything returns and unaudited.
Until then, I was indeed greatly annoyed but happy, because I finally had my three warm white LEDs.
Then fell after one week (Burn time approximately 15 hours) already from a pear. The credits I received immediately.
More than a star I can not forgive anyway.
The supplier PB-I am shipping from other orders so far very satisfied (z. B. LED transformers LED lamps and round).
