More people are choosing low voltage lighting solutions when it comes to outdoor lighting and, as we’ve discussed previously, it’s easy to see why they’re so popular. With that in mind, it’s important they’re getting the correct voltage to make sure lights are working [CD1] properly as incorrect voltages can potentially lead to lights not functioning sufficiently whilst there are other considerations to be made.
The first place to start when looking at resolving any issues is to figure out where the problem is. Once you have, solving it is going to be a whole lot easier. Common problems can usually be anything from fixtures not lighting correctly, to lights being dim or lights not even switching on and off like they should.
These are steps to take when testing outdoor lighting, looking at each potential issue:
- Bulb not working: If there’s a fixture not switching on check to see if the bulb has failed. You can do this by swapping it out for another one that you know is working. If the bulb is working, the next course of action is to test the voltage. To do this you will need a voltmeter. Voltage requirements for proper functionality is dependent on what types of fixtures are being used. LED systems do have larger operational voltage ranges (up to 16v), whilst halogen bulbs are more limited with ranges from 10.8 to 11.3 volts.
- Dim fixtures: a problem you may have is dim fixtures. Once this happens it’s important to remain patient and look for what might be the problem. Firstly, if your lights are getting dimmer as they get further aware from the transformer chances are it’s an issue with voltage drop. If it’s impacting all fixtures, do check for the mainline voltage and use a voltmeter to determine the true cause of what’s happening.
- Lights running continually: if this is the case with your outdoor lighting there will be an issue with your transformer and the photocell that’s likely attached to it. A photocell works together with lighting meaning the circuit will be open during daylight hours when sunlight is present, hence keeping lights switched off.
- Transformers: with the use of a voltmeter, transformers should be checked to ensure there are no obstructions or blockages to the photosensor caused by overgrowth, dust, or other debris. Once you’ve cleaned up the photocell, that should resolve the issue.
- Recurrent flickering of light: a tricky problem to fix is when your lights start flickering on and off. The source of such an occurrence is often difficult to find but there are usually two main reasons it’s happening. The first is a loose connection and second is wire load which heats and melts the wire. Locating the loose connection is problematic as the issue could be anywhere along the whole wire. You can determine wire load by checking the amperage on the wire and the transformer where connections are. A suitable solution for both problems is to run the wire again, ensuring connections are secure and wire runs aren’t missed.
