Cost to Install Outdoor Lighting?

The national average cost of installing outdoor lighting is between $2,000 and $4,500. At the low end, a project that only includes incandescent path and deck lights costs $2,000 to $3,000. A high-end installation that also includes designer, motion, and solar-power lights costs between $5,000 and $6,000.

Outdoor lighting allows you to improve your home’s security while also adding style to its exterior. It’s particularly important when you have well-defined outdoor spaces like a patio or deck that serve as a natural gathering place for a large number of visitors. This guide shows you how to estimate the cost of your outdoor lighting project.

On This Page:

Average Outdoor Light Installation Cost

Average Cost$3,500-$4,500
High Cost$5,000-$6,000
Low Cost$2,000-$3,000

Low-cost installations only include incandescent lights, while average installations consist of 20 LED lights. High-cost installations also have designer and solar lights with motion sensors.

Low-Voltage Landscape Lighting Installation Cost

The full retail price of low-voltage lighting is between $190 and $450, not including the transformer and wiring you would need for a new installation. They use a maximum of 15 watts of power and often less. These lights have die-cast aluminum fixtures and an anodized finish to prevent weathering.

Lamp Post Installation Cost

Professional contractors charge an average of $970 to install a lamp post and require about 13 hours of labor. Most of this cost is labor, so location is the primary cost factor. The cost also increases the further the lamppost is from the house, especially when the power lines are underground.

Cost to Install Outdoor Motion Sensor Lights

The national average cost of installing motion sensor lights is $370, assuming it’s a new installation. The low end is $220 if the installation site already has an electrical box. The upper end of the cost range is $550 for installations with smart LED lights and a smart-home controller.

Cost to Install Porch Lights

Professionals charge an average of $260 to install porch lights. Installation takes no more than an hour, so most of this cost is the lamp itself. These estimates don’t include the cost of installing an exterior power source. Solar-power lights don't require an external power source. A 16-watt model costs about $30 and takes eight hours to fully charge.

Cost of Installing Outdoor Security Light

The cost of replacing an existing outdoor light with a security light is about $300. This price includes the cost of the light itself and the labor to install it, but not the power source. Common locations for these lights include entry points to the house, including the front and back doors in addition to the garage. Security lights usually include a motion sensor.

Protect your home with a combination of these lights and a security system. Check out the cost to install a surveillance camera.

Floodlight Installation Cost

The cost of installing an outdoor floodlight assembly starts at $85 for parts and labor, which contains multiple bulbs. A floodlight produces a broad beam of high-intensity of light, typically for the purpose of illuminating a large outdoor area at night. This requirement means that floodlights have traditionally used incandescent bulbs, which aren’t very energy efficient. However, the latest LEDs can provide the lighting intensity floodlights require.

LED Floodlight Price

The cost of LED floodlights is slightly more than $10 for an individual bulb with power requirements ranging from 50 to 150 watts. These floodlights produce light with a brightness of 1,600 lumens in a 40-degree beam. They’re rated for 25,000 hours of use, which will last almost 23 years at three hour of operation per day.

Floodlight Pole Price

Floodlight pole prices range from $100 to $200, depending on the number and wattage of the bulbs it can hold. These models include the housing for the bulbs, which is designed to fit over a standard pole. Housings at the upper end of the price range can use 300-watt bulbs, which are typically used to illuminate streets and parking lots.

Tennis Court Flood Lights Cost

The cost of tennis court lighting depends on the size of the court, and whether it’s for recreational or tournament use. For example, a lighting kit for a single recreational court around $13,000, including parts and labor. The cost increases to $17,000 for a tournament court.

Sodium Flood Light Operating Costs

The cost of operating high-pressure sodium lights can be up to 2.5 times greater than LED lights of equivalent power. However, the initial cost of LED lights is greater than sodium lights.

You can determine the point in time at which LED lights will be more cost effective by first subtracting the cost of the sodium lights from the LED lights. Next, determine the difference in hourly operating costs between the two types. Finally, divide the difference in purchase cost by the difference in hourly operating costs to determine the number of hours needed for the LED lights to pay for themselves.

Cost of Sports Flood Lights

The cost of hiring outdoor lighting pros for a football stadium is between $18,000 and $25,000, assuming metal halide flood lights. This cost largely depends on the brightness required. Switching from metal halide lights to LEDs reduces energy costs by 65 percent. This difference reduces operating costs from $90 per hour for metal halide lights to $30 per hour for LEDs. In addition, the metal halide lights in sports floodlights require replacement every one to three years, while LEDs typically last more than 80,000 hours.

Cost to Replace Exterior Light Fixtures

The cost of replacing outdoor lighting ranges from $65 to $175 for labor, depending mostly on location. The cost of the fixture itself starts at $20. Other factors that can affect replacement cost include features of the fixture and wiring complexity.

DIY vs. Hire an Electrician for Outdoor Lighting

Electrical wiring is the most important consideration when deciding whether to hire an electrician for outdoor lighting repair and installation. A replacement of a bulb shouldn’t require an electrician, but even simple repair jobs often require replacing and rerouting electrical cables. A local landscape lighting contractor should always perform these tasks since building codes often require it.

Tara Dudley, Landscape Designer, Landscape Project Coordinator and Owner of Plant Life Designs, notes that “Your local landscape contractor can also handle installing an outdoor lighting system as long as there is an exterior outlet to connect to, done by a licensed electrician.”


Why is landscape lighting so expensive?

The reason landscape lighting is so expensive is that it’s subject to weather effects. “Still, landscape lighting systems usually come with a lifetime warranty, which can bump up your initial investment.” says Dudley. Temperature extremes, rain and snow require exterior lighting to have much sturdier materials such as cast brass. The wiring on exterior lights must also be highly water-resistant to last for years with little maintenance.

Are LED landscape lights worth it?

LED lights are more economical than incandescent bulbs and sodium lamps in the long run. Most LED landscape bulbs are between 6 and 15 watts, making them an economical choice. However, the initial cost will be higher, especially for applications that require high-intensity lights. The challenge in deciding to use these lights for landscaping is to calculate the point in time at which they pay for themselves.

How many low-voltage LED lights can a transformer handle?

The number of low-voltage LED lights that a transformer can handle depends on the total wattage of the lights. For example, eight 12-watt bulbs require a total of 96 watts, so you would need a 100-watt transformer for this application.

Do outdoor lights use a lot of electricity?

The electricity that outdoor lights use depends on their purpose. Holiday lights typically use only five watts each, but some holiday displays use thousands of these lights.

How much does it cost to run an outside light?

The cost of operating lights depends on the power it draws and the cost of electricity. Assume for this example that you have a 15-watt bulb, and the cost of electricity in your area is 10 cents per kilowatt-hour (kWh). The cost of operating this bulb is 15 x 10/1000 = 0.15 cents per hour.

How much does it cost to install a light post?

The cost of installing a light post is close to $1,000, assuming it’s a new installation.
