Low voltage (12 volt) systems are popular for landscape lighting for many good reasons. Low voltage systems are perfect for creative highlighting of trees, gardens, artwork and other landscape features. Low voltage fixtures are easy to install. Low voltage cable can be buried in a shallow trench, run through conduit or buried underground. A low voltage system is flexible. You can easily move fixtures to accommodate plant growth or to change lighting effects. Low voltage systems are safe and energy efficient. Transformers reduce standard voltage from 120 volts to a safe 12 volts. There is no risk of electrical shock to children or animals if the cable is accidentally cut. Lamps use less wattage and may not have the brightness of 120 volt, higher wattage lamps.

The first step in designing any lighting system is to determine what you want the light to do for you. Walk around your property, look out your windows and doors, and think about the kind of mood you would like to create. Look for possible focal points for dramatic accent lighting or plan for soft but safe pathway lighting. Create romantic shadows with subtle moonlighting or make entertainment areas come alive with bright party lighting. Next; review the techniques of accent lighting. Select the technique you feel best achieves the mood you with to create. Some light will "spill" from the accent areas. Work outward from these accent points to fill in areas with path or spread lighting. Balance and subtlety are key tools in path and spread lighting. Try out different techniques, and have fun discovering the beauty of your yard at night. Be sure that when you place your fixtures they will not interfere with lawnmowers, traffic or be a source of irritating glare inside your house or to your neighbors.

Low voltage systems require the use of transformer to reduce standard 120 volt power from your home to 12 volts. To determine the transformer size you will need, add up the wattages of all lamps you plan to use. Select a transformer that matches as closely as possible the total lamp wattage. For example: if you have 11 fixtures all rated at 24.4 watts-you will need a 300 watt (VA) transformer. (11 x 24.4 = 268.4 watts). Generally, the total lamp load should not be less that one-third the transformer's wattage rating, nor exceed its maximum wattage capacity. If your total wattage is too high, either divide the load between two transformers or use a more powerful transformer. Refer to the transformers section.

Too Symmetrical
a common problem found in pathlights: lights placed too closely and evenly makes the path or driveway look like a runway. Try staggering the lights, creating something of a zig-zag pattern from one side to the other. Also, refrain from putting pathlights equally on opposite sides.

Unbalanced Lighting
Do not place outdoor lighting fixtures in areas that will divide a yard. Make sure the light is balanced amongst the entire canvas of the property. You want to draw the eye around the entire yard, not necessarily toward one specific area. You especially don't want to create a hard "border" of light around your property line.


How to minimize Voltage Drop

The closer your lamps are placed to the transformer, the higher their voltage (and wattage) readings will be. Those farthest away will have lower voltages. If a cable run is too long, or it too many lights are being powered by a single transformer, noticeable voltage drop may occur. Voltage drop causes the lights farthest from the transformer to become dim. Voltage drop can be minimized in several different ways:

use heavier gauge cable 8 gauge K-15503 BK 10 gauge K-15504 BK
use a higher rated transformer
multiple taps 12-13-14
use multiple transformers
shorten cable lengths
reduce individual fixture wattages
reduce the total number of fixtures on a run Voltage drop can actually work to your advantage if differences in lamp brightness levels are not objectionable. Lower voltage will extend the life of a lamp, requiring less frequent replacement.
Selecting Mounting Accessories

After you have selected fixtures, lamps, transformers and cables, the only thing left is to select mounting accessories. These might include stems, stakes, bollards and shielding accessories.


Designing Line Voltage Systems

Line voltage (120 volt) systems are used where brilliant illumination is required for safety or security, for lighting large areas, or when you must light from farther away, such as up lighting large trees. In many cases, a landscape lighting design can be developed using both line voltage and low voltage components. The same steps used to design a low voltage system apply when designing landscape lighting using a line voltage system. Focus attention on the key points of interest using accent lighting. Provide for safe access of walkways and stairs. Illuminate activity areas as needed to maintain the mood you wish to achieve. Installation of a line voltage system is more complicated than a low voltage system. We recommend always working with a professional electrical contractor to make sure that your system is installed correctly and meets local electrical codes and requirements.

Lighting Techniques
Correct lighting techniques will highlight your important features and create the perfect amount of drama in a yard. Find out what techniques works best for your home's architectural features and garden accents.

Highlighting
This is a common and quite useful technique in outdoor lighting. Highlighting is created by placing a spotlight at the base of an outdoor feature. By varying the distance and angle of the light fixture, you can experiment with different lighting designs. For example, trees often need two or more fixtures to provide sufficient illumination.

Silhouetting

By placing a spotlight behind the feature, aimed towards an adjacent wall, you can create an illuminated backdrop. This dark outline of the object is useful for showcasing plants and other dense features. It looks especially striking in the sunset.

 

Scalloping - By varying the position and angle of the lighting fixture from silhouetting, you create a lighting technique called scalloping. By aiming the light straight up from the base of the fixture, it creates a cone-shaped illuminated backdrop. This works best with symmetrical objects, creating a dramatic and elegant sensibility.

Shadowing

A similar technique to silhouetting, shadowing also places the fixture towards the base of the feature, aimed towards an adjacent wall. However, the goal is to create a softer shadow, and often works best with a tree that has open, delicate foliage. The effect of the tree's movement in the wind is sure to add drama to any home facade.

 

Grazing - The grazing technique is placing an upright fixture very close to the surface of a feature to bring out its unique texture. It is the perfect technique for an old tree with complex and interesting bark, or a stone wall with lots of relief since it brings out light areas and dark areas at the same time.

Wallwashing - Wallwashing creates a soothing and even glow that comes off the wall or facade it's pointed towards. For best results, place the lighting fixture a few feet away from the feature, and give it a sideways angle. By shining along side the wall, it maintains an even and somewhat subtle ambient lighting for the nearby area. A wide angle flood light with low wattage is recommended for this, as opposed to a spotlight.

Moonlighting - Create moonlighting techniques by placing a large fixture with a full glare guard high up inside a tree, and angled downwards. This effect looks like moonlight shining down through the branches. It causes attractive shadow patterns on the ground to appear, plus it provides a very natural and beautiful lighting effect.

Downlighting - The downlighting technique is similar to the moonlighting technique. Place a fixture high up, inside a feature like a trellis, tree, or eave, and cast downwards over a large area. Place the light higher if you intend to illuminate a large portion of the yard, and lower if you wish to illuminate a path or garden.

 

Accenting - Any lighting that draws special attention to a specific feature is considered accent lighting. Specifically angled uplighting or downlighting can be used as accent lighting, to point out an architectural design, plant, or other feature. Try using a narrow beam spotlight from a hidden fixture to add a flair of mystery to your accent lighting.

Pathlighting is created by placing small fixtures along the borders of walkways, driveways, and patios. It is important that the style of these path lights be considered carefully. It is also important to be sure that they are positioned to illuminate the path, but also placed so that they avoid being kicked, moved, or getting in the way of the lawnmower.
