Adding Outdoor Lighting Without Running New Electrical Wiring

There is often a simple reason an outdoor area remains dark: the place where light is needed is not the place where electrical power was installed.

It might be the far side of a driveway, a gate, a detached garage, the side of a house or a section of the backyard. Adding a light seems straightforward until the project requires extending household electrical wiring to a location that was never designed to have it.

At that point, homeowners typically face a choice. Run new electrical wiring, use a solar or battery-powered light, find a nearby outlet or decide the project is more trouble than it is worth.

Those are no longer the only options.

Outdoor lighting is often less about finding the right light and more about finding a practical way to get power where the light is needed.

Why Adding One Light Can Become a Big Project

When electrical wiring already exists at the desired location, installing an outdoor fixture can be relatively straightforward. The challenge begins when the light needs to be somewhere else.

A conventional permanently powered fixture may require extending 120-volt electrical service from the house. Depending on the property, that can involve routing cable through walls, installing conduit, adding electrical boxes or trenching across part of the yard. Local electrical requirements and the complexity of the installation may also make professional installation necessary.

There is nothing wrong with this approach. Properly installed electrical wiring provides dependable power and may be the best long-term solution for many projects.

But the cost and disruption can be difficult to justify when the homeowner simply wants to illuminate one dark area.

Why Solar Became the Easy Alternative

Solar lighting became popular in large part because it removes the wiring problem completely.

A solar light can be mounted on a fence, shed, wall or post without extending electrical service to that location. For pathways, decorative lighting and many modest lighting applications, that convenience can make solar an excellent solution.

But removing the power cable means the energy has to come from somewhere else. Solar products collect energy during the day and store it in a battery for later use. The amount of light they can produce, and how long they can produce it, ultimately depends on the energy available.

That makes location important in a different way. Instead of asking whether electrical wiring is nearby, the homeowner needs to consider sunlight, shade, panel orientation, weather and seasonal changes.

For applications requiring brighter illumination or long operating periods, the difference between stored energy and continuous power can become significant.

Battery Power Has Similar Advantages and Tradeoffs

Rechargeable battery-powered lights provide another way to install lighting without permanent wiring. They can be especially useful when a light is used occasionally or when installing cable would be impractical.

The tradeoff is maintenance. Eventually the battery needs to be recharged or replaced.

That may be perfectly reasonable for a device that operates infrequently. It becomes less convenient when the light is mounted high on a building or expected to operate for long periods every night.

Convenience at installation can sometimes become maintenance later.

What About an Extension Cord?

If an outdoor electrical receptacle is nearby, the obvious solution may be a plug-in light and extension cord. For temporary lighting, that can be perfectly practical. The problem begins when an extension cord intended as a temporary source of power becomes a permanent part of the property.

Extension cords are generally not intended to replace permanent building wiring. Routing one along a wall, across a yard or through landscaping for months or years can create safety concerns that do not exist with a properly designed permanent installation. Cords can be damaged by sunlight, weather, landscaping equipment, foot traffic, vehicles and repeated movement. Connections exposed outdoors also need appropriate protection from moisture.

Trying to hide the cord can create additional problems. Extension cords should not simply be routed through walls, concealed inside building construction or buried unless the particular product and wiring method are specifically approved for that use. Electrical and building requirements can also vary by location, so permanent installations should follow applicable codes and manufacturer instructions.

There is also a practical issue. A long extension cord stretched across a property may technically make a light turn on, but it rarely looks or behaves like part of a professionally finished home. It can become a trip hazard, interfere with landscaping and create another exposed component that needs to be inspected over time.

An extension cord can solve a temporary power problem. It should not automatically become the permanent wiring plan for an outdoor light.

There Is Another Option: Move Low-Voltage Power

One way to simplify outdoor installation is to leave household electrical power near the outlet and distribute lower-voltage power from there to the light.

This concept is not new. Low-voltage landscape lighting has used it successfully for decades. A transformer or power supply converts household electricity to a lower voltage, and cable carries that power around the property to the individual lights.

The important idea is that the outlet and the light no longer have to be in the same place.

For homeowners, this can create a useful middle ground between solar lighting and adding a completely new household electrical circuit. The lighting receives continuous power, but line-voltage wiring does not necessarily need to be extended all the way to each fixture.

The outlet can stay where it is. The light can go where it actually belongs.

Coaxial Cable Can Carry Power Too

Most homeowners recognize coaxial cable as the cable traditionally used for television and broadband connections. But coax is simply a type of electrical cable, and it has been used to carry power in communications systems for many years.

Satellite television provides a familiar example. Electronics mounted outside at the satellite dish have traditionally received DC power over the same coaxial cable running back toward equipment inside the home.

That history is particularly relevant to Channel Master. The company has spent decades designing television reception products intended to operate outdoors and has extensive experience with RG-6 coaxial cable and powered outdoor electronics.

When Channel Master developed the Pro-Floodlight, that experience led to a different way of approaching the outdoor-lighting problem.

A Floodlight Powered Over Coax

Instead of requiring household electrical wiring at the floodlight, the Channel Master Pro-Floodlight uses a separate power adapter that converts household electricity to 24-volt DC.

That low-voltage power then travels over standard RG-6 coaxial cable to the light.

The system includes 25 feet of RG-6 cable and supports cable runs up to 150 feet when appropriate cable is used. This allows the power adapter to remain near an existing electrical outlet while the floodlight is positioned considerably farther away.

Once installed, the system behaves differently from a battery or solar light because the floodlight receives continuous power. There are no batteries for the homeowner to recharge and no solar panel that needs to collect enough energy during the day to provide light at night.

At the same time, the homeowner does not need to extend a new 120-volt household electrical circuit all the way to the floodlight.

The approach is intended to occupy the space between two familiar choices: the installation convenience associated with solar and battery lighting and the continuous power associated with conventionally wired fixtures.

Why Coax Instead of Another Type of Cable?

Coax may seem like an unusual choice for a lighting product, but it has several useful characteristics for outdoor installation.

RG-6 is widely available, relatively inexpensive and designed to be routed over meaningful distances. It can be cut to the length required for an installation and terminated with commonly available connectors. Quality RG-6 is also a familiar sight in outdoor television, satellite and broadband installations.

For Channel Master, there was another practical reason: coaxial cable is familiar technology. The company has worked with outdoor antennas, amplifiers, satellite systems and coaxial distribution products for generations.

Applying that experience to outdoor lighting does not require homeowners to learn a new cabling system. It simply uses a familiar cable to solve a different problem.

Permanent Does Not Have to Mean Complicated

There has traditionally been a fairly large gap between inexpensive outdoor lights that can be installed almost anywhere and permanent lighting that receives continuous electrical power.

Solar and battery products made installation easier. Conventional electrical fixtures provided dependable continuous power. Extension cords offered a quick temporary solution when an outlet was nearby. Each approach solved part of the problem.

Low-voltage systems offer another possibility: provide continuous power using a purpose-designed cabling system without requiring household line voltage at the light location.

That can be particularly useful for driveways, detached garages, sheds, side yards, fences and other parts of a property where useful lighting is needed but electrical infrastructure is not conveniently available.

It also creates a cleaner distinction between a temporary workaround and a permanent installation. Rather than leaving an extension cord exposed indefinitely or depending on stored energy, the power system can be planned as part of the lighting installation from the beginning.

Choose the Solution That Fits the Property

No single power method is right for every outdoor-lighting project.

If electrical wiring already exists where the light is needed, using it is often the simplest answer. If the lighting requirement is modest and the location receives good sunlight, solar may be difficult to beat for installation convenience. Battery-powered lighting can be useful where a device operates only occasionally, and an outdoor-rated extension cord can be practical for appropriate temporary applications.

When brighter, continuously available lighting is needed far from an existing electrical source, the decision becomes more interesting.

Before abandoning the project or assuming a new 120-volt circuit is the only permanent option, consider whether the power conversion can happen somewhere else and purpose-designed low-voltage cable can cover the remaining distance.

That small change in perspective can completely change an outdoor-lighting project.

Instead of asking, “How do I get an electrical outlet over there?”, the better question may be, “How can I get dependable power from the outlet I already have to the place where I actually need light?”

Once those two locations no longer have to be the same, many difficult outdoor-lighting installations become considerably easier to solve.
