The only thing I can give is: It may of course be that the lamps from different manufacturers which the Seller is constantly changing (billigster purchase price) which is then already really lucky thing possibly as "Russian roulette" I was lucky with the manufacturer:. Brilliant Made in Germany by 27442 Gnarrenberg! Have to some individual pictures!
I had previously bought at the hardware store exactly these lamps, from a well-known brand manufacturers and of course much more expensive! Nevertheless, life in the expensive product is just as long as the low-cost product purchased here! 10 for that price plus free shipping! When I drive an extra because of the lamps by car to the hardware store, there are the fuel costs to me in any case the construction market is not close I have quite a few kilometers drive! Even if times 1 or 2 lamps sooner give up the ghost has nevertheless saved!
I bought this product on 2 September 2012 and to date 30 September 2013 only 2 pieces are defect ie more than 1 year has passed! Since you can not complain! We have a 3 hob lamp in the kitchen because we need bright light and therefore the lights are very often in operation!
Thank you for reading, and I hope that I could help at a evt.Kaufentscheidung with my review! Mfg Thomas Müller
