Indeed effectiveness is beyond measure. By cons, pay almost 13 euros per bulb remains very expensive .... The supplier is serious and respects the delays. He dutifully packs his products but which are, in turn, not very well secured their original philipps Case. result, despite all the protections taken by the provider at the time of packaging, little precaution taken by the carrier made the 4 bulbs were walking on within their original packaging ... PAs very reassuring and they work well, it is likely that they have clashed during the trip (delivered from poland !!!) and nothing says that this will have no influence on their service life (weakening or other). Too bad. it is mainly what explains an average score compared to a product that it appears on its promises, but expensive all the same elevé.
