2 of 10 already broken after only 2 months of operation

End April 2014 I ordered 10 of these energy-saving lamps. The company Light Supplier Delivered quickly and easily.
Since June are the first 5 of these lamps in operation. The other five are still on the shelf as a substitute.
The lights make a nice warm light, exactly what I wanted, I was satisfied.

After only one month of operation (about 2 hours per day) was the first of the lights completely. Annoying when the price of the lamps, but can occur even once. 14 days later then made already the second lamp limp. They only light up with a fraction of the normal brightness, strictly speaking, it glows more, also smell the base of the lamp, because where the electrical system's inside, heavily charred.

Defective Two out of five in just two months, this is now something much. I wrote to the supplier via e-mail and asked for replacement. Here is the answer from the seller provider of light:
