The E14 LED bulbs, 4 Watt, warm white, 380Lumen, with 4 LED's Edison I am only somewhat satisfied. All lamps ordered the 5 have not yet given up the ghost. Whether they will persevere given 50,000 hours to be seen. Under the frosted glass dome that you can unscrew easily, sit 4 power LEDs each with 1 watt, on a heat sink. Probably a bit too small, because it is extremely hot after a certain time.
One star deduction because when the lights are hot after several minutes, the brightness decreases noticeably. In addition, the screwed-together elements of lamps are not glued and they can be broken down when herrauschrauben in 3 items. The glass dome läßst quite easily unscrew, but also the cooling block from the E14 thread, look no further Schlimmm because can be easily screwed together the 3 elements of the lamp again. However, it can happen if the cooling block is accidentally unscrewed, tear the cables that are soldered to the E14 base. The lack of the bonding is of course no matter if such a lamp may remain before the end of its life in the same socket.
The from me then ordered lamps are absolutely identical to the lamp offered at the following link. The only difference is that it is an E27.
