[RFI] Noisy LED shop lights

[Stephanie WX3K]

Install EMI filters on the lights. Most of the ballasts these days are noisy. I had an issue on 6 meters until i installed EMI filters inline. 

A typical filter costs about $10-15

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.
