hi reflectees!
i had sensor lamp problems right in my home. The only cure i found for 
them is using E-Type ferrite chokes.
The chokes avoid the internal oscillator energy being fed into the 
mains, plus they avoid the triggering of the internal switch.
I used SIEMENS N27 type E-cores, they are about 4 inches on a side. The 
functionality of the lamps is not affected whatsoever. Nor do You have 
to cut any wires, just coil them up in the double E-core.
It works from DC to daylight, so to speak. No other commercially 
available L and C configuration filters gave the immunity to RF that i 
achieved with the choke.
