Yes it is - I would also add that these work well for solar - however I have found I need to shut them off during the day so they can charge properly - if I don't turn them off they are dim when they light and or don't work at all. keep in mind I am using these in horse paddocks and e horses move around a lot which is probably triggering them more than a normal situation. Other than that they are great for the money and saving electric costs - I have moved to an electric flood light for the front
Yes, the unit comes with three adjustments: 1) Light level (how dark it has to get before it will come on); 2) Time (how long it will stay on once activated - adjustable from 8 seconds to 2 minutes); 3) Sensitivity (range at which motion is detected).
Yes. There is also a sensitivity adjustment for the level of ambient light used to trigger the light from night to daylight. In doing this the manufacturer eliminated the "test" setting on the duration that the light is on. Now the user is able to "test" the range sensitivity in daylight. The duration settings are still there except for the "test" selection. I don't pretend to know the logic behind this design but that how it works.
