[RFI] Low Voltage Patio Lights

Hello R March,

I have a 12 volt driveway lighting system that uses a 12 volt transformer. I 
makes NO RFI. It is produced and sold by "NightScaping"; part of:

Loran, Inc
1705 E. Colton Ave.
Redlands, CA 92374


I just called their number and got their answering system. So they are still 
in business. I have had my system for 10 years. No problems so far (fingers 
crossed, now that I've said that).

There Web page is www.nightscaping.com

My system uses a programmable clock and a "big" transformer. Fortunately it 
is fuse protected. Someone drove over a light and shorted it out. But no 
damage to the transformer.

Hope this help you.


Alan, W4LKE
