There are many benefits to increasing the value, safety and beauty of your home by installing a new landscape lighting system or maintaining an existing one. If you’ve experienced frustrations with inferior fixtures or a system not installed correctly then I think you will find this tip helpful.
How to install yourself:
1. Design the system
Design the desired effects throughout the garden by selecting the type and wattage of bulbs first, and then select a proper fixture to house the bulbs. Avoid the temptation of impulse buying the fixtures. After designing, purchase fixtures that come with a ten year or more warranty. Do it right the first time and sit back and enjoy for years.
2. Select a transformer
Purchase a quality transformer with a ten year or greater warranty for same reason listed above. How do you know what size transformer you need? It is just a matter of simple math, add up all the wattage of the bulbs you designed and leave yourself a little room for upsizing bulbs or adding a couple more fixtures in the future. For example 10 bulbs @ 20 watts each = 200 watts, so if you purchase a 300 watt transformer you have room for 5 more bulbs or the room to upsize 6 of the bulbs to 35 watts.
3. Select the wire
Look for direct burial 12 volt copper stranded wire. How do you know what size wire you need? Admittedly there is a lot more math to do in this category. Let me simplify by saying that a 2-12 gauge wire will support 100 watts if the run is no longer than 100 feet. Larger size wire will support more watts or longer runs and conversely smaller wire will support less watts or shorter runs. Do not exceed wire ratings. When in doubt use larger wire.
How to maintain your lighting system:
1. Change Bulbs
If you change the bulbs one by one as they go out you will be constantly changing bulbs. There is a better way, change them all at the same time. If it has been two to three years since you have changed the bulbs and 25% to 50% of your bulbs are out then you are a good candidate for this approach. There are different ratings in terms of how long a bulb should last. So when you replace them you may consider spending a little more for a longer lasting bulb. Try a 10,000 hour bulb. The average landscape lighting system is on approx. 2000 hours per year.
2. Adjust Fixtures
Look at plant material that has grown and adjust the angle or move the fixture farther back. See if a higher wattage bulb may now be necessary. At the transformer, check that the photo cell is not obstructed and/or reset timer if necessary.
3. Add Additional Fixtures
As the landscape changes over time and perhaps your impression of how your home looks in the evening changes, add fixtures that accomplish the effects and mood you are going for. Perhaps lowering the wattage on some and adding more lights would be more appropriate than increasing the amount of light coming from existing fixtures.
In closing, walk around your property in the evening and remember to consider safety as well as beauty when designing or maintaining your landscape lighting system.
