Choosing the right wattage for outdoor lighting is crucial to create a functional and aesthetically-pleasing outdoor space. The wattage determines the brightness and spread of the light. Selecting fixtures with wattages that are too low can result in dark, shadowy areas, while too high of a wattage can create glare. The ideal wattage depends on several factors, including the size of the area you want to illuminate, the purpose of the lighting, and the type of bulbs used. This comprehensive guide provides tips on choosing the perfect wattage for various outdoor spaces and lighting needs.
Determining the Right Wattage for Your Outdoor Space
When deciding on wattage for outdoor lighting, the first step is measuring the square footage of the area you want to illuminate. As a general guideline:
- Small areas (up to 400 sq ft): Opt for lower wattages between 25-60W. This includes accent lighting for gardens, spotlights on architectural features, and lighting walkways or steps.
- Medium areas (400-1000 sq ft): Look for medium wattages from 60-100W. This works well for illuminating patio seating areas, large sections of garden beds, swimming pools, and driveways.
- Large areas (over 1000 sq ft): Select higher wattages from 100-150W. This provides ample lighting for large yards, event spaces, parking lots, or exterior commercial areas.
Additionally, consider the purpose of the lighting and where it will be positioned:
- Accent lighting: Lower wattage bulbs around 25-60W are ideal for accenting architectural features, highlighting plants, or providing security lighting.
- Task lighting: For work areas like garden sheds, barbeque stations, and koi ponds, opt for 60-100W to ensure adequate visibility.
- Pathway lighting: Line walkways and driveways with 25-40W bulbs spaced close together for safe passage.
- Flood lighting: To brightly illuminate large open areas, install flood lights with 100W+ bulbs high up on walls or poles.
Finally, factor in the bulb material used, as this impacts brightness:
- Incandescent bulbs put out less light per watt compared to LEDs. Choose a higher wattage for adequate coverage.
- LED bulbs are energy efficient and brighter than incandescents. You may be able to use a lower wattage.
- Halogen bulbs also produce bright light. Calculate wattage based on the size of the area.
By taking into account the application, location, and bulb type, you can narrow down the ideal wattage range for your unique space.

Choosing Light Bulbs for Outdoor Fixtures
The type of bulb used in outdoor lighting fixtures also impacts the brightness and necessary wattage. Here is an overview of common outdoor bulb options:
Incandescent
Incandescent bulbs are inexpensive and come in a wide range of shapes and styles. However, they are very inefficient—90% of the energy consumed is lost as heat. This means they provide less light compared to LED or halogen bulbs of the same wattage. When using incandescents, choose a higher wattage bulb than seems necessary to sufficiently illuminate the space. The exception is with low-voltage fixtures, where standard wattage guidelines apply.
LED
LED bulbs are extremely energy efficient and long lasting. They come in a variety of color temperatures and work well in all outdoor fixtures. LEDs produce very bright, focused light, so you can typically use a lower wattage than other bulb types. Just ensure the fixture is properly rated for LEDs, as they require proper heat dissipation.
Halogen
Halogen bulbs are similar to traditional incandescents but burn brighter. They are a good choice for accent lighting and floodlights. Halogens run very hot, so be cautious using enclosed fixtures. When calculating wattage for halogens, stick to the standard guidelines based on square footage.
Fluorescent
Fluorescent bulbs like CFLs are not as common for outdoor lighting. But they are very energy efficient and affordable. Opt for CFLs made specifically for outdoor use with waterproof casings. Determine the wattage based on square footage, since fluorescents put out less light than LEDs or halogens.
Consider the pros and cons of each bulb type before making outdoor lighting purchases. Combining different bulbs can provide both aesthetic appeal and optimal illumination.
Choosing the Right Outdoor Light Fixtures
Once you’ve determined the ideal wattage range, select fixtures suited for the bulbs and spaces:
Wall Sconces
Wall sconces efficiently direct light downward or outward. Opt for sconces with:
- 25-60W bulbs for accenting architecture
- 60-100W bulbs for illuminating entries or gardens
Place sconces 5-6 feet apart for continuous lighting along paths.
Post Lights
Freestanding post lights work well for patios, pathways, or lining driveways. Based on the height:
- Short post lights: 25-60W
- Tall post lights: 60-100W+
Space lights 6-10 feet apart along linear areas.
Floodlights
Floodlights distribute a wide, powerful stream of light. Use floodlights with:
- 50-75W bulbs for lighting yards
- 100-250W bulbs for large areas like parking lots
Position floodlights high up on walls or posts to maximize coverage.
Spotlights
Narrow spotlights focus light directly downward or on architectural elements. Use spotlights with:
- 35-50W bulbs for highlighting plants
- 50-75W bulbs for illuminating building features
Aim adjustable spotlights carefully to highlight specific design elements.
Pendants
Pendant lights hang above to cast light in all directions. Ideal wattages include:
- 25-60W over tables
- 60-100W to light seating groups
- 100W+ for large reception areas
Hang pendants at least 7 feet high to maximize light spread.
Combine several fixtures with the appropriate wattages to light up your entire outdoor area beautifully.
Tips for Designing Outdoor Lighting Plans
When designing an outdoor lighting plan, keep these key tips in mind:
