[RE-wrenches] 110Vac LED resistance to weak grids in developing world

[Ray Walters]

Personally I love my latest LED lights.  They have gotten substantially 
better just in the past year.  We have some 8 watt units in our kitchen 
that illuminate just like a 35 watt halogen, beautiful color rendition, 
not that blue they used to have.
I especially like my new 1000 lumen spotlight that lights up brighter 
than a car head light in a package slightly larger than the old mini mag 
flash lights.
However, I have no experience with ham radio, or theRF interference 
issue.  We're WiFi, and cell at our house.  I do some audio recording, 
etc. and haven't noticed any extra buzz from the several LEDs I have in 
my basement studio.
