Wide-area illumination at low operating cost is the defining challenge that led landscape flood lights from Sunbright Lighting solve elegantly. These fixtures provide the coverage breadth that security and functional lighting require while keeping the energy consumption and operating costs at levels that make all-night operation genuinely practical.
The Physics of Wide-Area Coverage
Flood lighting coverage is fundamentally a question of beam angle and mounting height. A fixture mounted at 10 feet with a 120-degree beam angle illuminates a circle approximately 15 feet in diameter at ground level. The same fixture mounted at 15 feet illuminates a circle approximately 23 feet in diameter — a 50 percent increase in mounting height produces a 130 percent increase in coverage area.
This relationship means that investing in secure, higher mounting positions — eave-mounted rather than stake-mounted, for example — dramatically improves coverage efficiency and reduces the number of fixtures required for complete coverage of large areas.
The tradeoff is intensity. A larger coverage area from the same lumen output means lower intensity (illuminance) at the ground level. For security applications that require minimum illuminance for camera imaging, the mounting height must be balanced against coverage requirements.
Low Voltage vs Mains for Wide Coverage
led landscape flood lights operating on 12V low voltage systems are available up to approximately 1,500 to 2,000 lumens per fixture — sufficient for covering garden areas and driveways up to approximately 800 square feet per fixture at adequate illuminance. For larger areas or where higher illuminance is required (commercial security, large estate properties), mains voltage fixtures are necessary.
For the majority of residential landscape flood light applications, low voltage provides adequate coverage with the installation simplicity and safety advantages that make it the preferred choice.
Homeowners pairing led landscape flood lights with string lights led from Kings Outdoor Lighting for rope and string accent lighting in adjacent outdoor entertaining areas benefit from a landscape transformer with independent zones — the functional flood lighting can operate on a security schedule while the festive string lighting operates on an entertaining schedule.
Flood Light Placement for Garden Aesthetics
Security flood lights installed without aesthetic consideration typically look and function like security flood lights — functional, institutional, and visually intrusive. With thoughtful placement, the same fixtures can provide their security function while contributing to rather than detracting from the garden’s nighttime character.
The key principle is to direct flood light beams toward the ground rather than horizontally across the landscape. A flood light aimed downward from a high mounting point creates a pool of light on the ground below without projecting glare horizontally into neighbouring properties or creating the harsh silhouettes that horizontal beam angles produce.
