Are the porch lights photocell controlled? My neighbor had a controlled lamp at
the
end of his driveway. He replaced the incandescent bulb with a CFL. Horrible
noise!
I found that some of the older controllers will not work properly with CFLs.

All:
I ventured out at 4AM this morning and found the noise! It turned out to be my
neighbors CFL porch light. There are two lights on the porch and the one
that's not working is the one making the noise. The working CFL isn't exactly
quiet, but it's nowhere near as loud as the non-working light.
I used a battery powered HF rig with a make-shift coax antenna; just the
center conductor with the shield stripped away. I made sure I checked the
noise at the house before I left and used the same frequency on the portable.
That made the noise easy to identify once heard.
I also shut the mains on the house and kept them off just to make sure it
wasn't coming from my home. The noise was still there with the mains off. The
puzzling thing is the light switch issue....
The noise being generated by my neighbors CFL shifts in frequency (by several
kHz) when I turn off the light switch in MY shack! It will be interesting to
see what happens when he replaces his bad CFL.
So are there any quiet CFL's on the market? Lowes have them?
Thank for all.
