    After installing a few Zenith motion sensor flood light's I 
noticed that the power failures of just a few seconds seem to 
fool the light into going into an "over ride mode" that is 
designed for those who wire them to a switched outlet. This
mode makes the light stay on until reset (day or night!)
                I've found the the removal of a diode from the circuit
disables this function an hence the problem in the "allways hot"
wiring configuration. Cut (or unsolder) D8 on the model SL-5410
