LIGHT DOES NOT COME ON

LIGHT COMES ON FOR ONLY A FEW SECONDS

LIGHT STAYS ON OR

LIGHT COMES ON RANDOMLY

Is there power to the fixture?

Has the house circuit breaker tripped?

Is the wall switch ON?

Is the bulb screwed in completely?

Is the bulb good?

(Be careful not to overtighten.)

Is the light sensor able to determine darkness?

Cover light sensor with electrician’s tape. Wait 2-3 minutes to see if light turns on. If it does,

the sensor is receiving too much light. Install light sensor reflector (E) to deflect light.

Is the wiring to the unit loose?

TURN OFF POWER BEFORE CHECKING.

Is the light sensor sensing reflected light?

Cover light sensor with electrician’s tape. Wait 2-3 minutes. to see if light turns on. If it does, fixture is receiving reflected light. Install light sensor reflector (E) to deflect light.

Is the light sensor in a shaded area?

Shine a flashlight into the light sensor for 2-3 minutes. If the light turns off, the fixture is mounted in an area that does not allow enough

light to enter the light sensor. Install light sen- sor reflector (E) to direct light into sensor.

Is the light sensor good?

Shine a flashlight into the light sensor for 2-3 minutes. If the light does not turn off, replace the light sensor.
