Have unfortunately made the mistake not to test these lamps a little longer before I ordered me a second time '. That would have saved me to annoy me so. Wanted in the course of a renovation / a move to switch all lamps in the house to LED, and hab 'it ordered this product. After fast delivery I have the bulbs getest immediately and was delighted. The lamps provide a really nice, bright light. So I have imagined. The external processing made this a solid, high-quality impression. Economical they are to also be (if one can rely on the product description here because an indication of the power is not on lamps, even on packaging !!). The expected longevity of LED lighting together, my claims were therefore covered and I like to ready for something to spend more than halogen or energy-saving lamps. As described above, I have therefore ordered directly even more, so that I can incorporate "appropriate" light again in the event of a claim of a light source, and does not have to fit a lamp differently. Long story short: Despite renewed, fast delivery have not experienced 3 of 10 bulbs for the arrival of their "replacement". With a life expectancy of less than 3 days, which had 30% of my bulbs, I can therefore only advise against buying despite clearly described positive first impressions.
