I replaced some ceiling boob lights with flush-mounted LED panels -- they are a nice warm color, and I like them. I have a UHF/VHF antenna in my attic and I use it once a year to watch the Superbowl.

I found out this year that my reception is horrendous if those lights are on. The coax cable which goes from the attic to the TV downstairs runs right above the lights and the LED driver / PWM noise must couple with the coaxial cable. I'm not running anything fancy like RG6 since I just re-used whatever cable was already run up there from the 70s.

Florescent lighting in the bathroom?
