Good security lighting comes down to wide coverage, no dark blind spots, and smart activation. Use these three rules to map your protection zones before you buy.
- Find your vulnerable points. Walk the perimeter and pin down the entry points that matter — garage doors, side doors, dark alleyways, driveways, and rear sliders. Plan to mount fixtures high enough to lay a wide, unobstructed blanket of light over each one.
- Set mounting height and angle. For the longest throw, mount floodlights 8 to 10 feet up on eaves, soffits, or exterior walls. That height spreads the beam across large areas like driveways and keeps the fixture out of reach from tampering.
- Control your detection fields. With motion-activated fixtures, map the detection zones carefully. Aim sensors down toward your walking paths and driveway, and keep them off public sidewalks and low tree branches that trip false alarms in heavy wind.
With your perimeter zones mapped, select your gear. Work through the checklist for fixtures, power, and mounting.
1. Select Your Security & Floodlight Fixtures
Pro Tip: For wide coverage like driveways and backyards, use high-output dual-head LED floodlights. For entryways and side doors, choose motion-sensor fixtures or dusk-to-dawn photocell lights that come on automatically when someone approaches.
2. Choose Your Power Hub or Connection Strategy
Pro Tip: Settle your power source before you buy. Greenlist carries both commercial-grade 120V line-voltage floodlights (wired directly into a standard junction box) and high-output 12V low-voltage architectural floodlights that run off a landscape transformer. Match the fixture to your existing home wiring.
3. Secure Your Mounting Mounts & Accessories
Pro Tip: Security lights take constant wind and driving rain, so choose weatherproof round junction box covers, heavy-duty mounting brackets, and commercial-grade silicone sealant to lock out moisture and stop corrosion behind the wall.
Components on-site and ready? Follow this sequence to mount, seal, and test the system. Wiring a 120V line-voltage fixture means working with household current — if you're not comfortable at the panel, this is the step to bring in a licensed electrician.
- Prepare the mounting location. Shut off power at the main breaker panel before you touch any exposed wiring. For a 120V floodlight, confirm the exterior junction box is anchored to the studs or framing so it can carry the fixture's weight.
- Wire and seal the fixture. Connect the supply wires — black to black, white to white, ground to ground — with outdoor-rated wire nuts. Seat the base plate against the junction box, then run a clean, continuous bead of outdoor silicone around the top and sides of the plate to keep rainwater out of the electrical box.
- Aim and test the detection zones. Restore power at the panel. Wait for dusk to dial it in: adjust the lamp-head knuckles to cover your driveway or yard without blinding the neighbors, then set the sensor for your preferred motion sensitivity and run time. Switch it on and check it off your Greenlist.
