I recently purchased the above model. As per their customer service, I tried to decrease the sensitivity to 1, turn off the dualbrite and have the motion light come on at 1 or 5 minute intervals. The light comes on when motion is detected, however it stays on. Customer service was no help. Can anyone please advise me as to how to correct the problem? I previous had the same light fixture, but the glass panel shattered. Your help is greatly appreaciated!
