First I noticed the packaging negatively on: There's too much plastic and cardboard into one another and overall too much is not good for the environment; and when I again want to pack in the bulb or another, I have difficulty properly to get everything back together. While I realize that such an expensive bulb should be well protected by the packaging, but that she's not even here: the front it is only protected by a film that is at the other, even cheaper LED bulbs with a simpler but stable Boxes made better solved. This LED bulb has a luminous flux according to the description of 806 lumens and is intended to replace a 60W incandescent bulb. I have lists of journals, according to the 800 lumens some are more than a 75W-Glübirne supplies and to my mind the brightness of the LED lamp is also approximately that of a 75W bulb is so bright and so better than described. The lamp I think is high quality processed; it is immediately after turning on light. It radiates from beautiful uniform light, the same warm white (ie slightly yellowish) is, as an ordinary light bulb. This LED bulb has a beam angle of 220 degrees, which is for an LED lamp in order; but which means that they do not deliver the light in quite as wide area, like a light bulb. (I have another LED bulb - by Toshiba, which has a viewing angle of 270 degrees, which is important for LED bulbs tip and is roughly equivalent to a light bulb.) It is provided with 62 grams already heavier than a light bulb, but this is for an LED bulb einwirklich light weight; and with me still has the weight heavier bulbs (including energy-saving lamps) endured loose any light. But: it is also a bit longer than an ordinary light bulb (an accurate value I will not name, because there are also different sizes of light bulbs), which already is a drawback for me: they do not fit into all lights inside. (There are also smaller LED bulbs: The other ones I've already mentioned above and by Toshiba, is no larger than an ordinary light bulb.) There is no indication of dimming (at least I have not found); of an LED lamp in this price range I expect no dimming, and no explicit reference in the product description, I'm not going to try it.
