The lamp makes a really nice and bright light. I was in this respect also very pleased with it. I use in my home LAN via the mains (dLAN). In the evening, always broke me the bit rate by a multiple one, so that the speed of the network went to zero. I've been looking for and be able to identify the lamps as the cause. If these are made, the dLAN works without problems. I have more LED lamps from other manufacturers such as LG in operation. These do not cause interference. Very shame really because I so now can not use the lamps for me. It would not have been really expensive to install a noise filter in the lamp. The disturbances may possibly even interfere with other technologies. But here I have no other experience. If you do not pay off the dLAN used lamps.
