Thanks again. I am not very as well versed in isolation of a power supply. These units seem to have ac input thru a diode bridge to the rest of the circuitry. I suppose if I had a schematic of the unit I might be able to understand it better. <p>Have you any suggestions on isolating the power supply?

Thanks for the reply Chris. I was hoping to find a simple solution such as being able to disable whatever it is that makes the unit stay on after a power interruption. Surely there is a very simple solution out there somewhere.

I am looking for a circuit for an IR/motion detector security light with the following specs.<p>Time on settable up to 12 minutes<p>110 volt operation<p>will not trigger during daylight<p>will only stay on the length of preset time regardless of how it is triggered. i.e., if the power is interrupted...
