Thanks Dave:

Looks like 3 cores will do the trick for the K9YC filter. Winding the cores
now. Neighbor is good for a Saturday install.

He told me it is a GLD LED 150 Flood light IP66

Man does it create the RFI!

If you add anything to your neighbors light, try and get a hold harmless 

If there is a fire, you have increased your liability by working on his 
electrical system.

If it were me, I would look for a commercial solution that uses Jim's 
process...  I am not sure if anyone is selling Jim's filters yet...  If 
not, someone is missing a big opportunity...

73, and thanks,
