We have just recently bought LED lighting and transformers from a local store. After installing, there's a noticeable flicker, most notably in the "little room" where you have ample time to look (and get annoyed by it).
I have already switched that single LED with another one to verify it's not a defect LED. Now that I'm convinced it's not the LED, I started looking for possible causes.
It seems that this might be caused by not using the right transformer. As I'm just a layman and before going to my local seller to confront him with this, I'd like to be sure I'm on the right track.
