1. Many LED bulbs for household use and the normal power grid stink of plastic / flame retardants, if you let it burn longer, until they are warm. In small rooms (there I test them much) interferes with the fast, especially since it's very unhealthy for sure. This did not smell, is indeed almost entirely of glass and metal.
2. To date, a small start-up delay, this most (LED / energy saving) bulbs were not here.
3. So far, the color behavior of the LEDs left to be desired. There were variations on red, yellow, white and green. This one has the desired light yellowish tone, which is perhaps more than 2700K 2600K direction. TIP: If that is too yellow, it may, for example, with "5-pack greenandco E27 LED bulb lamp 7W matt (replaces 50W) / 638lm / 3000K (warm white)" try to 50W, however, corresponds.
4. Power consumption: 6W for 810Lumen ("60Watt"), this lamp is top.
5. Durability: 25000 hours, it is at the top. Whether this value is reached, I do not know yet, but I will report.
6. Significance: Glass and metal are now times unbeatable!
7. Nostalgia: Who depends on the light bulb, can be accessed here. Only the color is a bit yellow, so
8. Design: Find top send most people.
9. Brightness: rather slightly lighter than you'd expect for the specified lumen / wattage.
Disadvantages:
1. Non dimmable. Of course, is only a disadvantage if you need that.
2. The natural light spectrum as a whole does not meet the sunlight, nor the old bulb, but felt like at least when the light bulb (a little yellow).
