[RFI] NO NOISE LED BULBS / flourescent replacement

[Jim Brown]

Retired EE NA6O, with serious RFI chops and  good lab has looked into 
some Edison-base LED bulbs, but I've not seen data on any tube 
replacements. His website is well worth a look. We know each other from 
the NorCal contest club.

My home is 100% LED, mostly are reasonably quiet, but a few specialty 
types in "architectural fixtures" in a home we bought from a flipper 20 
years ago are mondo noisy, and are the only alternative. One fixture 
wipes out local FM broadcast. I'm all LED both to save money and make 
backup power easier. I'm lighting two buildings with about 100W when 
half of the lights are on.

I'm much too old for the cost of the bulbs to pay off, but I love that 
it greatly reduces the required scale of my power backup system, which 
is a 600Ah 48V LiFe Battery bank, a 6kVA inverter, and a gen that runs 
on propane that is loafing keeping up with household stuff and an 
support balls to the wall contesting.
