Fast delivery, but that's what is good. I use these bulbs in 6 garden lamps. There were 2 pears after 1 year (!) Defective. These were replaced by the new light bulbs here. But every 1-2 days they are broken again. All other old bulbs burn more reliably. Coincidence or not? Oddly always burn in the shortest possible time by only the new lamps. A technical error or wet I can not make. Meanwhile, I have used up all 6 new bulbs ... and get rid of this definitely no longer order ....
