Default Fluorescent light RFI solved

When it was finally dark, my wife turned them on to get the full effect.
To my horror, the AM radio two rooms away was instantly and completely
obliterated with RFI. I ran out to the shack and confirmed noise all the
way up to 20 meters.

The next day, I removed his lights and installed mine, and I was extremely
pleased to note not a hint of noise on any frequency, unless the receiver
was 6 inches from the light.

His lights: Bright Inch by Elite Lighting.

Mine: SlimLite by Hera Lighting.

Thanks for posting this, Al. As we get into more and more expensive
electricity, there's ever more pressure for all of us to reduce electrical
consumption by using fluorescent lighting, much of which results in
completely unacceptable rfi noise levels. Does anyone know of a database
that rates various brands as to rfi?


Not really antenna related, but...

They are ostensibly Part 15 compliant, so one could look at the
certification paperwork they supplied to the FCC.

I wouldn't count on huge amounts of item to item consistency, even
within the same brand and model. Based on my admittedly anecdotal data,
there's a fair amount of manufacturing variability, so unless someone is
going to go out and collect data on a statistically significant sample
(which practically means tens or hundreds of units tested), any set of
measurements is valid only for the item measured.
