What is a Transformer in Landscape Lighting?

Investing in outdoor lighting is wise. Sun Bright  Lighting transformers are the best one available and the greatest option for a low voltage outdoor lighting system since they are made for simple installation, consistent performance, and long life.

In the middle of every landscape lighting system is a transformer. Low voltages between 12 and 15 VAC are created from the current. The efficiency of this conversion determines how well the transformer regulates the voltage output and how much energy is consumed throughout the process.

You may buy with confidence knowing that all Sun Bright Lighting transformers are covered by a manufacturer's 100% money-back guarantee. Each one has magnetic secondary circuit breakers for each 300W common circuit as well as timer and photocell receptacles. Some of them feature cabinets made of waterproof stainless steel.

The wattages of landscape transformers fluctuate widely. They are connected with the quantity of lighting fixtures put in at your establishment. While others are 300, 400, or 600 watts, some of the units are 40, 60, and 120 watts.

To boost the automation of the lighting at your company or home, they either contain a connection for your own controls or a 24-hour timer. For the purpose of powering the light fixture, the transformer can be switched on and off, or you can use a control of your own.

Advanced Options and Features:

Landscape transformers come in three different basic varieties: single-phase to ground, three-phase to ground, and four-phase to ground. This circuit has two phases, and the two phases are connected by a single wire. The connection of the lights should always be taken into account when installing them.

The three-phase system is the finest in terms of wire. It offers a simple method for switching from single-phase to three-phase and vice versa. Four-phase is connected to the ground by three wires, while three wires connect three-phase to it. By identifying the wires, short circuit formation should be avoided.

Please make sure to inquire about installation instructions for the equipment from your supplier or technical staff. These transformers are a great option for your outdoor lighting needs because they are made to run numerous sets of fixtures simultaneously.

The landscape transformer is best for energy efficiency because it has a lower heat removal rating. You can be confident that doing this will result in lower electricity costs.

When is a transformer for outdoor lighting used?

If you wish to install a different landscape light fixture, you can't merely connect wire and plug in conventional fixtures. Transformers for landscape lighting must always be used before choosing any other electrical equipment for usage at home or on a facility.

Your home will be powered by 120vac, or 120 volts of alternating electricity. Even if the voltage in your building may be higher than 120 volts, the light fixtures only need 8 to 12 volts of direct electricity. The transformers' work is clear in the way they reduce the high input voltage to produce a low output voltage so you may use low voltage devices. You cannot operate more than one set of lights at any same time without the transformers.

The transformer for the landscape lighting offers a centralised location to manage all the lights, making it simple to regulate them. You won't need to activate numerous switches to turn on the light fixture if you select this option. It can be inconvenient to manually turn on each light when it's raining. You may turn on all the lights at once using the landscape transformers.

The earthing part of the transformers is necessary for reducing the shock risk at a facility. This is not to mean that you shouldn't exercise caution; if you're not being careful, you could still get shocked.

How can I calculate the size of the transformer I require?

The overall wattage needed for your facility determines the size of transformer you need, not its dimensions. The total number of installed light fixtures serves as a predictor for the wattage. The transformer gets bigger as there are more lights.

For instance, if you want to utilise 30 lights that each use 5 watts, you'll need 300 watts in total. It is advised to increase spare capacity by 20%. Consequently, the optimum choice would be a transformer that can generate an output of 360 watts or slightly more.

Your power load dictates the size of the transformer.

100 watts are equal to 20 fixtures at 5 watts apiece.

Here, opting for low voltage led light fixtures can save energy because they consume fewer watts than other light sources. Additionally, you'll need a smaller transformer as a result of this.

Where should a Transformer for Outdoor Lights be Placed?

Landscape lighting is a wonderful method to enhance the beauty of your home, but if you use it carelessly, you may create a huge mess. You can install your transformer for outdoor lighting securely and correctly using the information in this tutorial.

How to install a transformer for landscape lighting is a question we get a lot. Making sure you have the proper transformer first is the best way to go about doing this. You shouldn't try to install it if you don't have the proper transformer. You must choose the proper location for the transformer before you can properly install a landscape lighting transformer. Here are a few of the most popular locations where your transformer can be installed:

Transformer Placed to the Ground

- A transformer that is anchored to the surface of the ground, typically on a concrete block, or to a wall or pillar. The most popular kind of transformer is this.

Step 1:

The transformer should be placed roughly where it will be mounted. The distance between the bottom of the transformer and the ground must always be at least 12 inches. Make a mark on the top hole with a pencil. Drill a hole about an inch deep with a hammer drill in the top hole you marked. Next, put a masonry anchor and screw in the hole and secure them there. The transformer can be hung on the anchor screw by leaving about a 1/8-inch gap after threading in the anchor screw.

Step 2:

Mark the bottom hole of the transformer when it is suspended vertically. Drill the lowest anchor sleeve hole while moving the transformer out of the way. Together, insert your masonry anchor and screw into the hole, and then use the screwdriver to tighten it down. You can now tighten down the top screw for the transformer once the bottom screw is in place.

Step 3:

Measure how much wire is required to go up inside the transformer while it is in place, then remove the extra.

Underground Transformer:

- A transformer buried beneath the earth. This is more difficult than it appears since a professional must dig up the entire area surrounding the transformer.

How do I Setup Outdoor Lighting?

Your land may be enhanced perfectly with the accurate outdoor lighting, and installation is simple.

Low-voltage outdoor lighting can increase your home's curb appeal at night and give it an extra layer of protection. These outdoor lighting systems are ideal for showcasing stairs, plants, stonewalls, and other notable landscape. Due to the system's use of 12 volts of electricity, DIY installation is extremely secure.

Choose your Lights:

Selecting your lighting is the first thing you need to accomplish. There are numerous different lighting options available. While outdoor spotlights can draw attention to particular objects, floodlights can illuminate a large area. Thanks to pathway lighting, visitors looking for your property will know where to go at night.

With a flashlight, you may choose what kind of lighting to deploy in certain places. Use a flashlight with a spot and flood mode switch at night to test out various lighting combinations in various places.

Variety Of Lights:

We will be installing low-voltage lighting today, which can be plugged into any outdoor GCFI outlet and is wonderful for adding a decorative touch or illuminating a walkway. We are using a lighting kit that contains all the required parts, but if you are constructing your own or enhancing an existing kit, keep in mind to pick a finish that fits.

Step 1: Overview of landscape lighting

Low-voltage landscape lighting is a straightforward upgrade that can have a significant impact on both the safety and security of your property as well as how it appears at night. There are only three components needed for installation: a transformer, low-voltage electrical line, and the fixtures. These can be placed along walkways, steps, and driveways, or aimed up at trees, walls, and fences. If you've never done wiring before, installing this kind of system doesn't have to be complicated.

The home current is reduced by a transformer to only 12 volts. It must be connected to an outdoor electrical outlet with GFCI protection, a "while-in-use" cover, and a large plastic box that shuts over the power cable. The transformer's capacity must be sufficient to power the system's lights. Between the fixtures, there is a little trench where the cable is buried. You may give your house and yard a warm light at night as long as there is an electrical outlet close by.

Step 2: Arrange the Parts

On the ground, the walkway light fixtures will be placed at a distance somewhere between 8 and 10 feet.

Lay the low-voltage wire along the concrete pathway, following the line of the light fixtures. Lighting systems that are 200 watts or less can use 14-gauge cable, whereas systems that are 200 watts or more can use 12-gauge cable. String the cable under or around any obstacles you encounter, such a fence or a bush.

Step 3: Rotate the Sod

Clear the path by relocating the light fixtures. To remove the top layer of grass, which is about 12 inches from the edge of the walkway, use a plain shovel. Fold the sod over after pulling up on the handle to separate the grass from the dirt. Continue along the walkway in this manner at all times.

Scratch a trench in the ground where the wire will go with the shovel's blade corner.

Step 4: Bury the Landscape Lighting Cable

Place the low-voltage landscape lighting cable in the trench. Leave a little extra cord at each fixture point if you want to connect to the light fixtures. While leaving the cable extending from the ground near each fixture, smooth the soil over the trench. To keep the cable for each fixture above the grass, slice the detached sod where the fixture will be placed and fold it back over the soil.

Step 5: Connect The Transformer

To reach the external electrical outlet, the wire must be elevated. The cable's 12 inches of rubber insulation can then be removed with wire cutters. The transformer has two terminal screws. To keep the cable in place, you must tighten the screws.

Near the outlet, insert a wood stake into the earth. The transformer is then attached to the stake. (It may also be fixed directly to a home wall.) After removing the outlet's "while-in-use" cover, plug the transformer in.

Step 6: Make Holes For Component

Reposition all of the lighting fixtures, making sure they are all evenly spaced. The initial fixture needs to be set up as close to the walkway's edge as you can without projecting in any way. (If the fixture extends into the path, it will be frequently struck by passing pedestrians.)

Use a long steel punch or a big screwdriver to make a hole in the earth for the fixture's stake. Never use a hammer to force the fixture into the ground.

Step 7: Connect the Electrical Wires

The cable sticking out of the sod can be covered by the two connection sections hanging from the bottom of the light fixture. Press them together until you hear a click. As a result, the connectors' pointed points might puncture the cable and establish contact with its wires.

The fixture should light up because the transformer is hooked in, indicating a strong connection. If it doesn't, check the bulb or unsnap and resnap the connector.

Step 8: Install the Light Fixtures

Fix the lighting fixture to the ground stake made of metal. Till the top of the stake is above the ground, drive the fixture and stake into the ground. Verify that it is not bent to one side. Put the cable and connector at a depth of about 2 inches under the sod and into the soil.

Install the remaining fixtures in the same manner.

Step 9: Change out the Sod

Once the lighting fixtures are placed and functional, rake the sod around them. Use the shovel to trim the sod if required around the light fittings. Apply pressure to the sod and soak the area with water using a garden hose

How can Low Voltage Outdoor Lighting be Dimmed?

A landscape lighting system can be made to function flawlessly in a variety of ways, but it is hard to predict how it will appear until everything is installed and prepared for use.

Light has the drawback of being difficult to imagine. Even if you have carefully prepared your arrangement, it could seem a little too bright when you first flick the switch.

You need a transformer that can be dimmed if you want to dim landscape lights. With certain transformers, a 12V dimmer can be used. Not all LEDs can be dimmed, and non-dimmable bulbs won't function properly with a dimmable transformer.

Now, we discover.

  • What can you do if your landscape lighting is too bright?
  • With a conventional dimmer, lights can be dimmed.
  • Is it possible to dim landscape lighting or not?
  • Which type of transformer you require?

What can you do if your landscape lighting is too bright?

It's not necessary to install a dimmer if the landscape lights you've chosen are too bright. Although they limit your flexibility, they may help you save money and achieve your goals.

First, if the lights are too brightly glowing, you can try to relocate them a few inches away. A gel filter can be used to change the brightness of your light.

To assist in sleep, you employ lighting. Only a portion of the light will pass through the filter. This is a very cost-effective option.

However, it takes a lot of time because each filter needs to be cut to size and fastened to the light so the weather won't wash it away.

You shouldn't anticipate that the lighting will alter in your garden.

If your lights are not sealed, you also have the option of replacing the bulbs with dimmer ones. Again, it takes a little time, but the cost isn't too bad. Even if you can't regulate the brightness, once you're done you'll have a consistent light.

With a conventional dimmer, lights can be dimmed.

An outdoor system can employ the conventional dimmer switch. It is not a suggested option for the majority of transformers. To find out if it's okay to do so, you could send an email to the customer service team.

Theoretically, it seems to work out great and be simple to do. The dimmer does not require wiring into the circuit following the transformer. The electricity is downstepped as it travels from the mains to the transformer and then the dimmer.

For this, a 12V dimmer is required. You'll need to consider mounting and waterproofing the switch. The cost-effectiveness of purchasing a dedicated transformer is substantially greater than adopting this method.

Is it possible to dim landscape lighting or not?

There are some landscape lights that cannot be dimmed. It depends on two things whether you can dim your lights or not.

  • The transformer can it be dimmed?
  • Can the lights be dimmed?

You can dim your lights even if the transformer is not there. You require more than one element. It's crucial to remember that this only applies to the bulb and not the entire fixture.

All you need to do is purchase a dimmable light bulb if you purchase an outdoor fixture with changeable bulbs. Make sure the lighting is dark throughout.

Which type of transformer you require?

Now that the issue with the dimmable lights has been resolved, it is time to handle the transformer. It's likely that you will need to replace your transformer if it isn't dimmable.

Because they are much more expensive, don't expect to locate a dimmable landscape lighting transformer on Amazon.

When replacing your transformer, there are a few things to keep in mind.

Your lights should be able to be handled by the new transformer. It is simple to overlook the fact that a transformer that won't be overloaded by your setup is the most crucial consideration when looking for dimmable choices.

You shouldn't get a 200 Watt transformer if you utilize 200 Watts of lights because you should only be using 80% of your transformer's capability. Upgrade to a 300 Watt option at the very least to avoid power fluctuations.

You're going to get digital dimmable transformers because they are a real option. You will receive a phone that will enable you to use the internet to alter the phone's dimming settings.

The position of your transformer must also be taken into account. If you are outside the coverage area for your internet service, do you need a signal booster?
