Why Light from Above?
If we were given a choice, we would all light our nighttime landscape with moonlight. But since we can't control the moon, we find another way. Downlighting is that way.
With downlights, we simulate the light of the moon. We create the feeling of moonlight. Of course, we know it's not real, but we chose to suspend our disbelief - a term from the theater. When we immerse ourselves in a play or a film, we know it's not real, but pretend it is - we suspend our disbelief. This is the secret of landscape lighting. We create lighting that appears to be natural, that feels natural, but is (in reality) luminaires skillfully placed and aimed.
Downlighting from Trees - Moonlighting
Mounting fixtures high in trees, projecting their light through branches and leaves - nothing is more beautiful than the resulting dappled light. This is the number one best way to light driveways, lawns, patios - really any area that needs low level illumination. There are some key considerations before you embark on moonlighting.
Since downlights are typically mounted 20 to 30 ft. high, they require working from a tall ladder or lift. Do not undertake the installation of these lights unless you have the right equipment, the skill, and experience to work safely on a ladder. If you are a do-it-yourselfer, you may want to hire a pro to mount your moonlights. Arborists are well equipped to work in trees, as are most landscape lighting pros.
The best effect is the appearance of dappled light on the ground or hardscape area. To achieve the dappled effect, the light must project through branches and leaves. To find the best location, stand on the surface to be lit. Look up into a nearby tree to follow the trunk to about 20 ft. high. That would be the minimum height. Keep following the trunk up another 10 ft. and note how many branches and leaves obscure your view of the trunk. Settle on a height and position around the circumference of the trunk that you estimate will result in the best dappled pattern.
Note that it may not be possible to find trees with branches below 30 ft. In this case, you can still mount the lights up the trees, but the effect will be oval pools of light instead of dappled lighting. This can be a nice effect, but it does look more artificial that dappled light.
Woodsman Downlight - Available in integrated LED and lamp-ready models.
- Fixtures & Lamps
The best fixtures for this application are the VOLT® Woodsman Downlights. These feature advanced engineering to make them easy and fast to install. They are available with LEDs integrated into the fixture body (for simplicity) or MR16 LED lamp-ready (for design flexibility). Also available, the Tree Light Management Kit includes screws, spacers, and zip ties for a clean tree-friendly way to attach fixture wire to the tree.
Downlighting from Under Gutters, Soffits, Gazebos, and Arbors
Many houses come with downlights already installed under gutters, soffits or other overhangs. These are usually 120-volt fixtures cut into the surface and wired into the house electrical system. These lights typically project downward and create nice cones of light illuminating the house siding. Unless you are an electrician, you should not attempt to service or change these 120-volt fixtures.
If downlights are not already present in these locations, then you have a choice of other fixtures you can mount to the siding or underside to achieve the same (or different) effects.
- Lighting House Sidings & Garden Beds
The easiest way to illuminate the sidings on your house are using uplights - usually, spotlights stake-mounted near the base of the house. However, if you have a place to mount them, you can use downlights instead. These are best attached to the vertical wall just beneath the overhanging soffit or gutter. Some prefer the appearance of the downlight compared to the uplight. These downlights can also serve to illuminate the garden bed near the house as well. Select beam angles to achieve a wide (60º) or medium (36º) coverage.
- Lighting Gazebos and Arbors
Mounting lights in the eaves or beams inside gazebos or arbors are ideal ways to achieve comfortable low-level illumination. These fixtures are best positioned in corners or under peaks so they are mostly hidden from view. Use wide beam angles and low wattage lamps to keep the light level low and maintain a relaxing and romantic ambiance.
- Fixtures & Lamps
Another useful fixture is the VOLT® All-Star Tommy Light - an excellent choice for a downlight when protected by an overhang. With an attractive straight-cut housing, the fixture can be angled using the knuckle or when directed straight down.
VOLT makes other specialty fixtures that can be used creatively for downlighting applications. VOLT's linear LED Hardscape Lights can be hidden under gazebo eaves or railings. The VOLT Buddy Pro is a tiny fixture that can also be hidden from view and provide widespread downlighting. Care should be taken with these fixtures that they are never within direct view of the occupants since the unobstructed LED chips are very bright when viewed directly.
Other fixtures that can be used as high-performance downlights are the 12-volt LED Floodlights. These are, however, much too bright for gazebos and arbors. Instead, they can be used attached to sidings or under soffits to provide bright wide area lighting. These are a great choice to replace security spotlights and for security-sensitive areas such as garage entrances.
