How Bright Should Your Outdoor Lighting Be?
Homeowners often struggle to find just the right level of lighting for different outdoor areas of their property. Over-lighting creates glare and light pollution, but under-lighting creates safety hazards. Many also make the mistake of focusing on wattage rather than lumens. Distinct areas on a property have different lighting requirements, and it’s important to understand the metrics for lighting and how to apply them.
Lumens vs. Watts?
People often make the mistake of assuming that more wattage means better lighting. While this is fundamentally true for any specific class of lights, it misses the main point. Lumens are standardized across all lights. Conversely, different types of lights, such as LED versus incandescent, can have radically different lumen outputs at very different wattage levels. A 10-watt LED may produce as many lumens as a 60-watt incandescent bulb, for example.
The smart approach is to ignore watts entirely when looking at lights. Focus on the lumens.
Lumen Recommendations for Different Outdoor Areas
The needs of different outdoor areas can vary significantly. This is especially the case if your place has a mixture of security, safety, and aesthetic needs. Here is a breakdown of the optimal lighting setups for specific zones.
Pathways and Walkways
We recommend using bulbs with 100-200 lumens spaced 6-8 feet apart. Lower lumen levels add effective mood lighting, and the extra bulbs provide maximum coverage for safety. This strikes a nice balance between decorative accent lighting and safety.
Stairs and Steps
Once more, 100-200 lumens per fixture is sufficient. This is enough to illuminate treads and risers without producing glare on highlighted edges.
Driveways
500-1,000 lumens is ideal for a driveway with multiple fixtures. If you’re going to use one or two lights to illuminate a driveway, we recommend moving up to 1,200-2,400 lumens. This makes home and driveway identification easier at night. Consider adding motion-activated lights for greater safety in your driveway.
Entryways
Wall-mounted lanterns or sconces work nicely at 400-1,200 lumens. You want enough illumination to allow security systems to see who is at the door. Likewise, this makes packages more visible. House number identification is easier from the street when the front light is closer to 1,200 lumens. Something closer to 400 lumens is ideal if you’ll have lots of visitors or if you want to focus on aesthetics.
Patios and Decks
The target for lighting on a patio or deck is 100-200 lumens per square foot. This affords good-looking lighting for entertaining while also achieving sufficient ambient lighting. If you expect to use your patio rarely for socializing at night, you may want to up the target to 250-400 lumens for greater safety and security.
Many people use 50-100 lumens in string lights to maximize coverage while adding ambience. Wall scones are also good for decks and patios. Consider installing a dimmer switch and using a higher-lumen system so you can get the best of both worlds when it comes to ambience and security.
Gardens and Landscape Features
50-300 lumens are sufficient for all but the tallest trees. Uplighting is great for showing off the form of a nice tree. Low-level light can highlight beds. Many people layer different types of lighting to show off the full range of the garden and landscape.
Accent and Architectural Lighting
The range is significant here because a lot depends on what you’re trying to accomplish. 150 lumens is sufficient to backlight plants or sculptures, for example. Conversely, 100 lumens for a single fixture may be necessary to wash an entire wall on a wide angle.
Security and Floodlights
Finally, security and floodlights typically call for some of the more aggressive levels at 700-1,300 lumens. These systems should eliminate blind spots that allow intruders to cross your property. Positioning floodlights at corners and setting them up with crossing fields of illumination is best. However, always try to avoid pointing lights straight into your neighbors’ yards.
Factors That Affect How Many Lumens You Need
Several factors affect how many lumens a light needs to be.
- Purpose. Task lighting generally demands more illumination per square foot, at 30-50 lumens versus 10-20 for ambient. Be aware of this, especially when thinking about areas for outdoor cooking or grilling.
- Illuminated space. Filling a larger space, especially with one or two lights, requires more lumens to be effective.
- Placement and beam angle. Narrow beams concentrate light better, requiring fewer lumens. Wide beams are good for general illumination, but they also require more lumens to address an area.
- Height. Illumination weakens with distance, so you want to use higher-lumen systems for scenarios where lights will be higher.
Mistakes to Avoid
Foremost, avoid over-illuminating an area. It is wasteful and causes light pollution. Use no more lumens than necessary. Pay attention to the beam area, too. A high-lumen light with a narrow beam may leave coverage gaps.
Avoid applying uniform brightness to an area. Layering with different levels, such as light accent lighting and intense landscaping lighting, gives a house more visual life.
Finally, consider using dimmers. Fine control of lighting levels makes a difference. You can use lower levels of ambience and then pull up the illumination when you need task lighting.
FAQ
Should I focus on watts or lumens when choosing outdoor lights?
Focus on lumens, not watts. Lumens measure actual light output and are consistent across all bulb types. Watts measure energy use, which varies widely a 10W LED can produce the same brightness as a 60W incandescent bulb.
How bright should pathway and stair lighting be?
100–200 lumens per fixture is recommended for both pathways and stairs. For walkways, space fixtures 6–8 feet apart. This level is bright enough for safety without causing glare.
What’s the right lumen level for a front entryway?
400–1,200 lumens works well for entryways. Aim closer to 400 lumens for aesthetics or high foot traffic, and closer to 1,200 if you want house numbers to be visible from the street or need clearer security camera coverage.
How many lumens do I need for a patio or deck?
Target 100–200 lumens per square foot for everyday entertaining. If safety and security are a priority, bump that up to 250–400 lumens. Installing a dimmer gives you the flexibility to switch between ambience and full brightness.
How bright should security and floodlights be?
700–1,300 lumens is the typical range for security lighting. Position floodlights at corners with overlapping fields of coverage to eliminate blind spots. Avoid aiming lights directly into neighboring properties.
What are the most common outdoor lighting mistakes?
Over-illuminating is the biggest mistake it wastes energy and causes light pollution. Other common errors include using uniform brightness everywhere instead of layering different levels, and ignoring beam angle, which can leave gaps even with high-lumen fixtures.
