Having bought a chandelier in a DIY market that works with 12 of these bulbs. I soon found myself with HS bulbs after 2 months of course the warranty does not work for the bulbs, thank you C .... The supermarket selling 2 ampoules of its own brand for 10 euros that take 2 shortly, I turned to Amazon ... For the same price, I got 10 of Osram brand and it works ... It speaks for itself, thank you Amazon.
