The landscaping lights turn out to be 12 volt AC powered and not 12 volt DC
powered. All the suggestions about a car battery and/or an Astron or other
linear power supply now go out the window. -M

I have a neighbor across the street that just installed a $400+ landscaping
lighting system. These are KILLING me on HF when they turn on at night. I
even get noise on 220 and 440 FM from them. We have changed out the power
supplies..no help. I am going to try a CAR BATTERY to see what happens.
That might isolate the problem to the power supply. But if that doesn't
work, I guess I will have to try some clip of ferrite blocks. I wonder if
these are the same thing you are working with and if so, what's the fix?
The neighbor has been 'receptive' but I don't want to keep getting in his
face about it until I am on to the fix - Mike

I bought some cheap LED bulbs on ebay which range from bad RFI to
horrible RFI. So while they were cheap (maybe as low as $6), I
recommend staying away from Ebay. They also produce less light than
advertized (the 9 watt bulbs were dimmer than the 7 watt ones I got at
Lowes). The quality control was terrible.

Is anyone familiar withthe LED light bulbs made by Cree (www.cree.com)
They look nice and are half the price of the competition.
They are available from Home Depot, on-line only through the end of this
month, and then in the stores.
I'm (obviously) interested in whether they generate rfi/noise!
