I have converted many battery powered devices to AC adapter in the past. This time around I am using a Motion Sensor light which takes 4 C batteries and is used to light a closet.
When I connect a 6V, 1 amp adapter to it, it does work but errantly. If it is off and motion occurs it does turn on but other than that it has a mind of its own. It will stay on for hours at a time or turn off for a while and then turn back on with no outside influence.
I am starting to think that somehow the adapter is affecting the sensors in it. By no means am I an expert in electronics and would appreciate any suggestions. My best guess is maybe I need to filter the supply coming into the light somehow.
Below is the product I am using.

Here is the adapter I am using, the 5V version. I was using a 6V before, both yield the same results.
