LED lamps.
There are four types of LED lamps regarding elektrosmog.
1. Which make dirty electricity back to the mains net.
2. Which are transmitting dirty frequencies in the air ( what I call *dirty air*).
3. Which do both: so transmitting *dirty power* back in the line, and transitting *dirty air*.
4. Which do NOT transmit *dirty power* back in the line, and not transitting *dirty air*.
I have found overhere, that the LED lamps sold by Ikea are of thye 4th type.
Furthermore I want to point to a study by Prof. Balck.
It is in German, but there is Google translate or Babylon.

The radiation of direct LED goes even through a wooden plank!
