Landscape Lighting Tips
Add the finishing touch to your exterior spaces with well-planned outdoor landscape lighting. By Kelly Roberson
When it comes to lighting your landscape, a little goes a long way. That's because your eyes need less light outdoors than they do indoors in order to see light, shadow, and pattern. To plan your outdoor lighting, walk around your yard at night, envision how and when you want to use your spaces, and rely on these tips.
How light is seen during the day is different from how it is seen at night, a particularly important distinction when it comes to lighting pathways and other outdoor spaces. However, certain principles about lighting remain true.
For starters, light has intensity, or quantity emitted, and color. The color of a particular lightbulb can be found on the packaging; it is a number that ranges from 1800 kelvins (K), which is very red in tone, to 7500 K, which is a bluish white.
Whether indoors or outdoors, lighting is generally divided into three layers based on function.
Overall: Overall light provides illumination for a whole room or space.
Task: Task lighting is used for a specific purpose, such as to light a path.
Accent: Accent lighting draws attention to an object or area. This is usually accomplished with spotlights or floodlights.
A variety of bulbs are suitable for outdoor fixtures. Incandescent bulbs emit pleasing light but have a short life and consume more electricity. Halogen bulbs are more efficient versions of incandescents, typically with a longer life and less energy consumption. Fluorescents are now available in a more pleasing color range, last much longer, and consume less energy. While LED bulbs are more expensive, their costs -- which continue to decline -- are balanced by their extraordinarily long life and extremely low energy consumption.
Landscape lights that are located near a building with electricity can easily be integrated into your home's wiring system. Solar landscape lighting options exist, too, to power your landscape lights.
Outdoor Lighting Issues
Outdoor lighting issues differ from those of indoor light. For example, reflection is less an issue outdoors because most surfaces are dark and do not reflect light well. However, position and shielding are more important in outdoor landscape lighting in order to prevent glare.
Glare happens when a light source is too big or too bright; it can be blinding because it reflects directly in people's eyes. Exterior landscape lighting also needs to be particularly sensitive to direct versus indirect light. Direct outdoor landscape light, such as a downlight outside a side entry door, will brighten mostly the object it is directed at and little of the surroundings. Indirect light reflects on the surrounding surfaces to create a soft wash.
