This LED - lamp is a 100% alternative to a 40 watt bulb, it is felt even a little brighter. She exudes a warm, pleasant light, giving the equivalent lightbulb very, very close to. I lean now something out the window and say, it is like the light of a light bulb. The design is very well done and resembles a light bulb to wonderful without being overbearing or too large.
Of course, the price deters some from, we paid for our 7 copies each 13 (ie a total of 91). I see this acquisition as a lump sum, however, since the lamp will hopefully last for several years (4 year warranty by OSRAM). All in all, I'd seen from today's perspective, access to this lamp again, quite certain that nothing, but doing wrong here also nothing.
Here are some additional information, which unfortunately missing in the description, but are likely to be quite interesting.
Energy efficiency class: A +
Thread length: 2,7cm
Length piston: 6,2cm (ie what disconcerted looking out)
Finally, it only remains to say. Here, you do nothing wrong and do not only his wallet something good, but also the environment.
