[RFI] Noisy LED shop lights

[Dale Johnson]

I solved the RFI from shop lights.  I took the noise makers down boxed them up and returned and told them these lights interfered with my shortwave radio.  

Then ordered four more of the Sunco’s.

Great to hear, no pun intended.  I have 18 in one large garage and 6 in an other, I too am glad they are quiet...

After installing them I found lots of noise on 20 meters with peaks and valleys, to make sure the new shop lights were the culprit I turned them off and then the 20 meter band was quiet again.  These are Smart Electrican brand, model number LSL3300L42WH.  These are distributed by Menard, Inc. Eau Claire Wisconsin.  Made in China.  I purchased a couple more for my basement shop, but I’m going to return those.
