[600MRG] Low RF Noise LED Light Bulbs

[Bill Cromwell]

Hi,

Like Scott and some others I have not found any added noise from the LED 
lights. I haven't tried the florescent tube replacements. I took a 
portable AM broadcast radio up close and I heard noise from some of the 
bulbs at two inches decreasing to none at 4 or 5 inches. I know others 
are reporting horror stories but those are outside my experience. I 
started some years ago with Cree brand that I bought from Home Depot. 
More recently I have a mix of different brands with the same kind of 
results.

My electric utility bill has decreased. Additionally my ceiling mounted 
lights are not generating high temperatures in the overhead structure 
and insulation:)

73,
