Generally the flickering happens to lights that contain a photoeye. When your fixture turns on, its light bounces off of a nearby reflective surface tricking the photoeye into thinking its daytime. This turns the light off. As a result of the light turning off, the photoeye believes it is dark, turning the light back on. The time between flickers depends on the distance of the reflective surface from the light.

To test if this is what’s happening with your unit, tape a piece of cardboard over the light with a small hole just large enough to see if the light comes on or not. Go into a completely dark room with the switch turned on. If the light stays on and does not flicker, you now know the photoeye was being “tricked” by the reflecting light. It is imperative the hole is small enough to ensure the light will not reflect off of the walls, producing the same result and making you think the light is defective.

If the light still flickers and you care certain the photoeye is not being tricked, please call 800-786-329 to speak with a representative.

Notes: For many of our solar flood and security lights the solar panel is the photoeye.

The flicker can also be caused by other sources of light – such as a street lamp that turns on and off or headlights from passing traffic.
