Wiring and Testing Dusk to Dawn Outdoor Lights Fixtures

Electrical Question: I just installed a 150w dusk to dawn lights fixture and it wont light up.

The bulb is new, and a new switch. I have 120 volts in the bulb socket, but the light will not light up. Could it be transformer not putting out enough power to light bulb, or what?

This electrical wiring question came from: Garry, a Handyman in Oregon.

Installing Dusk to Dawn Fixtures

Installing dusk to dawn lights fixtures can be pretty straight forward, but every once and a while there may be a problem. Lets take a look at a list of check you can make to help get your dusk to dawn light fixture installed and working:

  • Make sure all wiring connections are well make and the wire connection is on firmly. The smaller light fixture wires can easily slip out of the wire connector and prevent connection.
  • Testing for voltage using an audible tester is fine, but remember that it will not indicate that the neutral connection is working.

Dusk to Dawn Fixture Switch Settings for Accuracy

  • Switch settings for Testing can not only be hard to read, but confusing as well. Make sure that the light fixture is not left in the Test mode or switch position.
  • The test mode allows testing in the daytime after the light fixture has been installed. This is a really handy feature especially for positioning the motion detector head.
  • Light bulbs must match the specifications of the light fixture otherwise damage may result to the internal circuitry of the light fixture. The size and watts of the lamps is important, and also the type of lamp. Some CFL lamps should not be use with some brands of dusk to dawn light fixtures.
  • If all of the above checks prove ok and the light fixture still does not work, then you may have a defective light fixture. Contact the store where you purchased your disk to dawn light fixture and request an exchange.
