Collection: Transformers - Low Voltage
Low Voltage Landscape Transformers
Most people don’t think about landscape lighting design very often. They rarely consider the possibilities, hardly ever wonder about their options, and probably don’t give lighting components a second thought.
Until the time comes to transform their outdoor spaces by creating a custom landscape lighting design.
Once that happens, you start wondering about the best way to lay out your lights. You wonder whether you’ll have enough light in one space, or too much in another. You might also wonder whether you really need a lighting transformer, or even, what low voltage transformers are.
You’re in the right place, because if you need a lighting transformer, you probably need a Top Notch transformer.
What Are Low Voltage Transformers?
Usually, the voltage that the lights, appliances and other items inside your home use is 120 volts, which is the standard voltage for current that comes out of your outlets.
Landscape lighting, however, is designed to use a much lower voltage – usually between 12 and 15 VAC.
The voltage supplied to any piece of electrical equipment, including lighting, televisions or appliances needs to match the voltage that item uses to operate. When they don’t match, equipment like low voltage transformers is used to “step down” the power, so that it can be used by the item in question.
If low voltage transformers were not used in this way for things like landscape lighting, the equipment simply would not work, and it could be very dangerous.
How Are Low Voltage Transformers Used for Landscape Lighting?
When your landscaper or designer is creating an outdoor lighting design, they will usually include a low landscape lighting transformer in the design. This piece of equipment will be wired to the 120 volt power supply, it will step the power down, and then that adjusted voltage power will be used to power your lights.
Most low voltage transformers, including our Top Notch transformers, can be used to power several different lights. So, you usually only need one for each lighting design.
Who Should Install Your Landscape Lighting Transformer?

As with any kind of electrical installation, a low voltage transformer for landscape lighting should only be installed by a licensed electrician. It can be very dangerous if equipment like this is not installed correctly.
Qualified and licensed electricians will also know exactly what kind of wiring and fittings to use to and from your low voltage transformer, and how to properly ground and protect the whole system.
Often, landscapers will assist the electrician by placing the light fittings and fixtures as per the lighting plan, but the final connection and testing should always be left to a professional. This also ensures that your outdoor lighting will meet code, and that you won’t be cited for any installation violations.
Which Low Voltage Transformer Do You Need?
There’s no one size fits all lighting design out there – and there’s no one size fits all solution for equipment like low voltage transformers.
The best way to ensure that you are getting the right size and type of equipment for your outdoor landscape lighting design is to work with an outdoor lighting expert and an electrician. They can ensure that you have the right size and quantity of all the equipment you need, and that the whole installation is safe and properly installed.
Landscape lighting systems can be a big investment, and the last thing you want is to use substandard equipment, resulting in the need for early repairs or replacement. Make sure you choose high quality products like our Top Notch transformers too – so you can start the whole project off on the right foot.
A great outdoor lighting system should work well, all year round, for many years to come, and with our quality products, yours will do exactly that.

So - you've put tons of work into designing and installing your landscape lighting. And it looks like magic! The neighbors will definitely be impressed.
But what about long-term use? How will you keep your landscape lighting looking great without having to manually turn it on and off every night? That's where photocell sensors come in.
Photocell sensors are light-sensitive devices that can detect changes in light levels and trigger a switch when those levels reach a predetermined point. In other words, they can be used to turn your landscape lighting on or off automatically at dusk - no need for manual activation required.
Your search for the perfect photocell ends here. The Eye-Opener 2100™ photocell is a super-functional light detection sensor and can meet a variety of needs and a range of situations. It is widely used in Outdoor Landscape Lighting Transformers.
Where are Photocell Lighting Sensors Used?
Photocell lighting sensors can be realistically used in any context requiring seamless light control. The most obvious instance would be landscaping, as many large residential and commercial property owners don't want to have to deal with the hassle of manually switching their lights on and off every time outdoor conditions change.
Even within this single use case, there are countless ways to incorporate light-sensing technology in an outdoor lighting system. Let's take a look at the most popular:
Landscape Lighting
The most common use for photocell lighting sensors in landscaping is to control outside lights. As darkness falls, the photocell sensor can detect this and trigger a switch that turns on outdoor lights, eliminating the need for manual operation.
Additionally, photocell lighting sensors can be used to control the brightness of outdoor lights. By using daylight level sensing technology, external lights can adjust their brightness according to how much natural light is available in an area. This ensures that external lighting is never too bright or too dim during different times of day, providing a consistent level of illumination.
Area Lighting
Area lighting is a great way to make sure that pathways, garages, and other outdoor areas remain well-lit during the evening hours. Photocell sensors can be used to turn lights on at sundown and off again at sunrise, or they can be programmed to respond only when motion is detected. This is perfect in terms of both convenience and safety. Automatic systems like these are essentially self-maintaining and require little to no human interaction. They provide the visibility people need, when they need it, without the added work that comes with maintaining traditional area lighting systems.
Security Lighting
Security lighting is an incredibly common component of any outdoor security system, and adding photocell sensors to these fixtures can also be quite beneficial. These sensors will detect reduced light levels and automatically activate the lights when motion is detected in their vicinity. This can provide an extra layer of safety against intruders, as well as reduce energy consumption since the lights only come on when they are needed.
Are Photocell Light Sensors Worth It?
As you should with every investment in life, you're likely wondering whether photocell light sensors are worth buying for your property. The answer depends on a simple question: do you enjoy convenience?
If you like to come home after dark and not worry about turning on the lights, a photocell light sensor is an excellent investment. The sensors detect when it's getting dark outside and turn your outside lights on for you automatically, saving you the hassle of having to manually turn them on each day.
Photocell light sensors are also great for security purposes, as their automatic activation can give the exterior of your home a lived-in look even when you're away from it.
Of course, it's important to recognize that photocell light sensors are only worth the cost if you're purchasing them from a reputable manufacturer. Not all light-detecting systems are made equal; it's best to do your research and read reviews before investing in one.
Special Considerations to Make Before Buying Photocell Light Sensors
Suppliers aren't the only thing you'll need to think about during the process - installation is another factor to consider. Many photocell light sensors are easy to install and require minimal wiring, but some more complex models may need a professional hand.
Several external factors such as ambient temperature and humidity levels, location of installation, and distance from any other sources of lighting also need to be taken into account. No matter which product you buy, it will ultimately only ever be effective if these conditions are in play. Again, doing research in this respect can help you make the best decision and configure a system that meets your specific needs.
