"In this world of dim and unpleasant eco and energy saving bulbs, this one really stands out. At last 'let their be light'; has meaning. They are dimmable for the occasions when the full power of these bulbs is not needed. Plus there is no waiting for the lamp to reach full brightness its instant. In this world where the government/European Union wants you to live in the 'dark ages' these bulbs are super bright. Buy now before they find a way to ban them! Although I rated reliability at 5 stars this is not based on a long period of use but I didn't want to wait 2 years or more to write the review."
