Not smd5050 and bad RFI

Asked specifically what kind of LED it is. The response was 5050, they sent 2835 LEDs as shown in the picture. which in itself is not bad. They just don't even know what they're selling. They're bright, much brighter than the old incandescent bulbs, as expected. It doesn't seem like you can choose which side lights up when you switch to a side for lighting. The reviewer mentioned RFI with their HAM setup. While I have not attempted to use a ham radio in a camper with lights installed, I have an FM stereo in my camper and with the lights on the radio reception is completely cut off. I doubt the FCC will approve them. I must now find a way to protect her. My original review gave these 4 stars for being bright and using less power, but now 2 stars for unacceptable RFI (radio frequency interference). They're cheap, plastic looks cheap, RFI shows cheap. To be honest I don't think they are worth the asking price because I have to add ferrite cores to cancel the RF interference. Update: Added ferrite toroids #43, this fixed the problem on 3 bulbs, 2 of them I couldn't fix with ferrite, maybe more experimentation will fix it, but for now I can't recommend these bulbs to anyone. The search continues
