How to Fix a Dusk to Dawn Lighting Problem

Hi Tony,
If the light fixture has a ballast then that is one component that can become faulty. A replacement ballast will be required if the the existing one is found to be faulty.
I hope this helps,
Dave

Hi Larry,
From what you have described, it may be that a component is faulty possibly due to excessive moisture. If after a period of dry weather the fixture does not return to normal operation then the faulty component will need to be replaced. Also make sure the light fixture is properly installed with weather proof gaskets as provided with the fixture and securely fitted to the surface to prevent water leaks.
I hope this helps,

Hi Pat,
Yes, the photocell may be faulty, however the wiring to the light pole should be checked with a voltage tester. If 120 volts is shown between the hot and neutral wire at the photocell then that will rule out a problem with the circuit. If power is normal try placing black tape over the eye of the photocell which should simulate darkness, which should activate the light fixture within a minute. Don’t rule out the possibility of faulty lamps either. If normal power is not present then it is time to do some electrical troubleshooting.
I hope this helps you with your dusk to dawn light fixture,

Hi Pat,
If an outlet on the dusk to dawn light pole is not working as well, the circuit is most likely protected by GFCI. If the outlet is GFCI then try pushing the Reset button. If the pole outlet is not a GFCI then look for an GFCI outlet in a nearby location, such as the front porch, or in the garage. I believe you will find a GFCI outlet that is tripped off and just needs to be reset.
Thanks for sharing your dusk to dawn light project with us,

Hi Ron,
Make sure the lamps that are installed are within the watt specifications for the dusk to dawn light fixture.
Adjusting the Light Bulb Socket Tab
When the power is off to the light fixture, adjust the center lamp base contact tab inside the light socket to make sure the tab is up slightly to ensure contact with the light bulb.
I hope this helps,
Dave

Hi Roger,
Make sure the replacement lamp conforms to the manufacturers specifications, or is the same as the original lamp which was operating correctly.
Double check the settings for Dusk to Dawn operation. Some fixtures may be set for the Low Light setting which will prevent the lamp from producing full light.
I hope this helps,
Dave

Hi James,
The circuitry for an individual dusk to dawn light fixture is designed for the watt limitation of each light fixture, so the current wiring connections you have described may be causing problems. When wiring two or more fixtures to be controller by a single motion detector, time clock, photocell, or any combination thereof, it is best to design the circuit for the total connected load, or the amperage of the circuit. Please refer to several article resources which are available which describe various options which are found by searching for Controlling Light Fixtures, and the article Wiring Hallway Lights and Switches may be helpful as well.
I hope this helps,

Hi Ellis,
Check to see if there is a sensitivity dial that you can adjust on the new dusk to dawn light fixture. Typically there is a dial for time duration and one for sensitivity. Also make sure you are using the correct light bulbs.
I hope this helps,

Hi Megan,
Intermittent electrical problems are the hardest to identify, however here are some items that may be checked for this outdoor light fixture:
Note: The circuit power to the light fixture should be turned off before inspecting or making any repairs.
Power Supply – Make sure the power is being provided from the circuit source to the light fixture and that the fuse is good.
Electrical Wiring – The circuit wiring and components should be rated appropriately, properly installed, and inspected and repaired as needed.

Light Bulb – Light bulbs are required to be replaced periodically with a compatible style type of lamp.
Photocell – A photocell typically turns the light fixture on and off and can go bad requiring replacement. Most photocells for street lamps are located on the top of the fixture enclosure.
Ballast and Starter – Depending on the exact type of light fixture, most sodium vapor, mercury vapor, or metal halide light fixtures have a ballast and a starter which can go bad an require replacement.
Damaged Wire or Connectors – Due to the heat produced by the light fixture, the wiring components inside the wiring enclosure may become damaged. Cracked wire insulation and wire connectors will require replacing and repairs as needed.

You may want to review the agreement with the Strata, especially with regard to the responsibility for the light fixture maintenance and repairs.

I hope this helps,
Dave

Hi Laura,
During the daytime when a dusk to dawn light fixture has power it will consume a very small amount of electricity which is required for the photocell sensing circuit to operate. Once the photocell senses darkness then the motion detector sensor circuit is enabled which will turn on the fixture lights only when motion is detected. The position of the motion detector light fixture switch settings will determine the sensitivity and operation of the light fixture.
I hope this helps,
Dave

Hi Jim,
It really does not matter if the light fixture is a dusk to dawn type or a motion detector. The problem is that the swirl type of CFL Compact Fluorescent Lamp is typically not dimmable, so they will not work well with a dusk to dawn light fixture which requires a lamp that will dim. The other problem with CFL lamps is that they are not rated for outdoor use, and they do not start well in cooler weather. Attempting to use a CFL lamp which is not the dimming type and rated for indoor use will only cause the life of the CFL lamp to be short.
This is will not be true IF the manufacturer of the CFL lamp states that it has the ability to dim, and it is rated for outdoor use, and I hope this happens soon – because the CFL lamp is a good energy saver.
Another quick note: The life of any fluorescent lamp is greatly reduced as it is turned On and Off often, however the lifespan is much longer when they are turned On less often and allowed to operate for longer periods of time.
I hope this helps,
Dave

Hi Alexandra,
I have never heard that a covered area would affect a motion sensor, however here are some factors to consider:
Most motion detectors not only sense motion but also detect heat which is radiated from a body in motion. This helps to prevent leaves and branches from activating the light. The installation height and the distance from the desired area to be detected will have an effect on the performance. Also, make sure the detector sensor head switches are set in the proper position. Lastly, make sure to read through the operating instructions that came with your motion detector fixture because some motion heads have a manual override capability which will either create a OFF, ON or AUTO function simply by toggling the main control, which is typically a wall switch.

Garry,
Check the wiring connections making sure of the polarity. I’m wondering if your just reading the socket voltage to ground or if you are getting a true 120 volt reading from inside the socket, which is a little tricky.

Also, make sure this dusk to dawn light fixture is rated to Handel 150 watt lamps. Outside light fixtures such as the dusk to dawn and motion detector type have watt limitations, and going over the rating could cause damage to the internal circuitry.

Be sure to check the settings on the unit to make sure they are configured correctly.

RD, I think they serve two purposes, one to save energy with a lower level light, then also to give a presence that the home is lighted to help ward off prowlers. The lower level of light serves as a nice lighted appearance for the home and helps visiting guests see your home as well.

The dimmer is not compatible with the circuitry of the motion detector apparently. You could have the motion detector head activate a small relay which would pass a dimmer controlled line through the contacts. I have used this set up for similar applications and it works great.

Tom – you cannot put a dimmer switch in place of the light switch because this will cause the motion detector to malfunction and may damage the device. The motion detector needs to have full power to operate. If you want the Dusk-to-Dawn feature, you need to purchase a Dusk-to-Dawn Fixture and use a normal switch. Then just adjust the settings on the fixture.
