Outdoor lighting serves an important purpose for safety, security, and decoration. Many types of outdoor lights are available, including pathway lights, floodlights, string lights, lanterns, and more. Some outdoor lights are designed to be hardwired into an electrical system, while others can be plugged into an outdoor outlet. Plug-in outdoor lights provide flexibility in placement and allow lights to be moved or rearranged easily. However, there are important factors to consider regarding electrical safety when using plug-in outdoor lights.

Can You Plug in Outdoor Lights Outside?
Yes, most outdoor lights can be safely plugged into exterior outlets as long as proper precautions are taken. The key factors when using outdoor plug-in lights are:
Using GFCI Outlets
Any outdoor outlets used for plugging in lights should have ground fault circuit interrupter (GFCI) protection. GFCI outlets shut off electricity immediately if a faulty ground is detected, which prevents shock or electrocution hazards. Standard indoor outlets do not have this safety feature.
Outdoor-Rated Cords
Outdoor-rated extension cords must be used to connect plug-in lights outdoors. These cords are designed to withstand exposure to weather and temperature extremes. Indoor extension cords can become brittle and hazardous when used outside.
Avoiding Overload
Too many lights plugged into a single outlet can cause overload and risk a fire. Check the amperage rating of each light strand and do not exceed the total rating for the outlet used. Spread lights over multiple outlets to be safe.
Proper Placement
Choose an outdoor location for plugging in lights that is sheltered from rain, sprinklers, puddles, and irrigation systems. Cover outlets and connections with weatherproof boxes or containers to prevent moisture damage. Avoid placing cords where they may be damaged by lawn equipment.
Inspect Frequently
Routinely check plugged in lights for damage to cords, plugs, or light strands. Discard any damaged lights immediately. Also check that outlet covers and GFCI features are intact.
Types of Plug-in Outdoor Lights
Many kinds of outdoor lights can be plugged in safely with proper precautions. Some of the most popular options include:
Pathway Lights
Low-voltage LED path lights are available in a wide selection of finishes and styles to accent walkways and gardens. These lights typically use a transformer to convert high voltage to a 12V system, allowing safe plug-in use.
String Lights
Outdoor string lights add decorative sparkle to trees, pergolas, and patio areas. LED string lights are very popular for their brightness, durability, and energy efficiency. Waterproof connectors help prevent hazards from moisture.
Floodlights
Plug-in floodlights provide bright illumination for gardens, driveways, and yards. Halogen or LED models are available. Use a weatherproof outdoor-rated extension cord to connect the light.
Accent Lights
Small accent lights can highlight architectural features, landscape elements, or holiday decorations. Low-voltage LED lights are commonly used for plug-in accent lighting.
Lanterns
Decorative outdoor lanterns made of metal, glass, or other materials add style while providing light. Electric and solar-powered options are available for plugging in or installing around outdoor living spaces.
Safety Tips for Plug-In Outdoor Lights
While most outdoor lights can be plugged in outside safely, following electrical safety guidelines is essential:
Use a GFCI Outlet
Always plug lights into a GFCI-protected exterior outlet. This safety feature will shut off power immediately if electricity is exposed to water.
Inspect Cords Frequently
Check cords for damage like cracks, loose plugs, and bare wires before each use. Discard any damaged cords right away.
Coil Extra Cord Length
Do not leave excess cord length laying in areas where it could become tripping hazard. Coil extra length neatly out of walkways.
Consider a Timer or Photocell
Using an outdoor timer or photocell sensor allows lights to turn on and off automatically at set times or based on darkness. This avoids leaving lights plugged in continuously.
Use Caution Around Water
Position plugs and connections away from sprinklers, rain gutters, and irrigation systems. Keep off wet grass or ground after rainfall.
Shut Off When Away
Unplug light strands before leaving home for extended periods. Accidental electrical hazards are possible if plugged in unattended.
Avoid Overloading Outlets
Check the amperage of all lights used and ensure the combined amount does not exceed the outlet’s rating. Overloading can cause overheating.
Keep Connections Dry
Use weatherproof covers or containers over all plugs, connectors, timers, and power strips. This prevents moisture damage.
Position Cords Carefully
Route cords along walls or posts where possible and avoid high traffic areas. Do not let cords cross under sod or grass.
Choosing the Right Outdoor-Rated Cords
Heavy-duty outdoor-rated extension cords are essential for safe use with plug-in lights outside:
Sizing the Cord
Match cord thickness to the power needs of your lights. For most residential lighting, a 16 or 14 gauge cord is sufficient. More lights or longer runs require a thicker 12 or 10 gauge cord.
Durability
Select cords made for outdoor use with durable PVC jacketing that resists weather exposure over time without cracking or deteriorating.
Water Resistance
Outdoor cords feature waterproof plugs and connectors that maintain electrical integrity when exposed to moisture. Look for UL-listing for submersible cords.
Flexibility in Cold
Cords stay flexible in low temperatures, allowing use in all seasons without becoming stiff or brittle when cold.
Heavy-Duty Construction
Reinforced cords hold up well to being walked on and driven over without damage to conductors. Sturdy materials prevent wear over time.
Sufficient Length
Purchase extension cords long enough to reach light locations without straining or pulling tightly. Avoid linking multiple cords together.
Grounding
Properly grounded cords provide enhanced electrical safety compared to ungrounded two-prong cords. Grounding reduces risk of shocks.
Tips for Plugging In Multiple Outdoor Lights
When using numerous plug-in outdoor lights, follow these tips for orderly setup:
Plan Locations Carefully
Map out placement of all lights first to determine how cords will be routed and the length required. Group together lights powered from the same outlet.
Label Cords
Use tags or tape to label the start and end point of each extension cord. This avoids confusion when unplugging or packing up lights.
Prevent Tripping Hazards
Use cable ramps, clips, or staples to securely anchor cords against walls, along floors, or underground. Keep areas tidy.
Consider Portable Power
For large or complex displays, use an outdoor-rated power strip or portable generator to provide multiple outlets in one location.
Check Ratings
Calculate the total wattage of all lights plugged into one outlet and ensure it does not exceed the circuit capacity to prevent overloading.
Test Lights Before Installing
Plug in and test light strings before hanging up to catch any defective bulbs or malfunctions. Replace damaged strands.
Use Timers Strategically
Use timers for some lights so everything doesn’t turn on at once causing a surge. Stagger start times.
Space Outlets Evenly
Position exterior outlets at regular intervals around the home to allow lights to be plugged in without long cord runs.
Keep Extras On Hand
Have spare bulbs, fuses, cords, and timers available for quick replacement if needed. Check lights frequently for problems.
Conclusion
Outdoor lighting can be plugged in outside safely by selecting proper cords and outlets and taking precautions. Key tips include using GFCI outlets, heavy-duty extension cords rated for outdoor use, avoiding overloading circuits, keeping connections dry, and frequently inspecting lights for damage. Planning ahead is also important when plugging in multiple lights to allow for orderly setup and prevent tripping hazards. With the right groundwork, exterior outlets can enable stunning and convenient outdoor lighting displays using plug-in fixtures. Just be sure to follow all electrical safety guidelines carefully. Enjoy lighting up your outdoor space!
