LED Technology & Light Output

LED Technology & Light Output

The lithonia lighting hgx led 2rh 40k 120 mo wh m2 utilizes advanced LED chips that deliver consistent, high-quality illumination without the warm-up time required by older technologies. The 4000K color temperature strikes an ideal balance—cooler than warm white but not harshly blue—making it perfect for security applications where you need to clearly identify objects, people, and vehicles.

Energy Efficiency & Lifespan

LED technology consumes significantly less electricity than traditional halogen security lights while producing equivalent or superior brightness. Our HGX series LEDs are rated for tens of thousands of operating hours, dramatically reducing the frequency of bulb changes. This longevity is especially valuable for hard-to-reach mounting locations like second-story eaves or high garage walls.


Motion Sensor Features & Settings

Motion Sensor Features & Settings

The integrated passive infrared (PIR) motion sensor detects heat signatures from people, animals, and vehicles within its coverage zone. You can adjust the sensitivity to minimize false triggers from small animals or blowing branches while still catching human-sized movement reliably.

Timer settings give you control over how long the lights remain on after activation—typically adjustable from one minute to several minutes depending on your preferences. Shorter durations conserve energy for occasional motion events, while longer settings work better for extended outdoor activities like unloading groceries or working in the garage.


Weather Resistance & Outdoor Durability

Weather Resistance & Outdoor Durability

Built for year-round exterior exposure, the HGX LED 2RH features weather-resistant construction that protects internal components from rain, snow, humidity, and temperature extremes. The white thermoplastic housing resists UV degradation, maintaining its appearance even after years of direct sunlight.

Sealed lens assemblies prevent moisture intrusion that could fog optics or damage LED drivers. All electrical connections use weatherproof junction box compatibility, ensuring safe, code-compliant installations that stand up to harsh environmental conditions.

Bright and reliable motion detection
I installed this lithonia lighting hgx led 2rh 40k 120 mo wh m2 above my garage and the difference is incredible. The motion sensor picks up movement from the street all the way to my front door, and the light is bright enough to clearly see faces on my security camera. Installation was straightforward with the included hardware.

Perfect color temperature for security
The 4000K light is so much better than the old yellowish halogen I replaced. Everything looks clear and natural, not washed out. I adjusted both heads to cover my driveway and walkway separately, which gives me complete coverage from one fixture.

Energy savings are noticeable
We replaced three old 500-watt halogens with these LED units and our electric bill dropped noticeably. The motion sensor works perfectly—sensitive enough to catch anyone approaching but not triggering from passing cars. Very happy with this purchase.

Great fixture once properly aimed
Took some time to get the sensor and light heads aimed just right, but once dialed in, this thing works flawlessly. The build quality feels solid and the white finish matches our trim perfectly. Only wish the timer settings had more granular options.

Holds up to Pacific Northwest weather
We get a lot of rain and this fixture has been completely weatherproof for over a year now. No fogging, no corrosion, no issues. The LEDs are still just as bright as day one and the motion sensor hasn’t had a single false trigger problem.

Excellent for deterring package theft
Installed this above our front porch after some neighborhood package thefts. The bright instant-on light when someone approaches is a great deterrent, and it makes accepting deliveries after dark much safer. The adjustable heads let me light both the porch and steps perfectly.

Common Questions About the HGX LED Security Floodlight

The integrated PIR motion sensor typically detects motion up to 30-40 feet away, depending on the size of the moving object and environmental conditions. The detection zone is adjustable by repositioning the sensor housing during installation.

Larger heat signatures like people and vehicles are detected at greater distances than small animals. You can fine-tune sensitivity settings to reduce false triggers while maintaining reliable detection of human-sized movement.

Yes, the lithonia lighting hgx led 2rh 40k 120 mo wh m2 is designed to retrofit standard outdoor electrical junction boxes used by most halogen security lights. The 120-volt AC power requirement matches typical residential wiring.

The mounting footprint fits conventional outdoor boxes, though you may need to adjust the mounting bracket depending on your specific junction box configuration. We recommend turning off power at the breaker and verifying wire compatibility before beginning installation.

LED technology in the HGX series is rated for tens of thousands of operating hours—typically 50,000 hours or more under normal conditions. At an average of three hours per night, this translates to over 45 years of service life.

Unlike traditional bulbs, LEDs gradually dim over time rather than burning out suddenly. Even after their rated lifespan, the LEDs will continue producing light, just at slightly reduced brightness. This exceptional longevity virtually eliminates maintenance for hard-to-reach mounting locations.

The weather-resistant construction handles humidity, rain, and temperature extremes well, making it appropriate for most coastal residential installations. The sealed lens assemblies and corrosion-resistant housing protect internal components from salt air exposure.

For extreme marine environments or locations with direct salt spray, consider adding a light coating of corrosion inhibitor to mounting hardware during installation. Regular rinsing with fresh water helps prevent salt buildup on exterior surfaces.

Yes, the built-in timer allows you to adjust the on-time duration after motion is detected. Settings typically range from one minute to several minutes, though exact ranges depend on the specific control module.

Shorter durations (one to two minutes) work well for driveways and walkways where you just need light while passing through. Longer settings (five to ten minutes) are better for areas where you’ll be working or unloading items from vehicles.

4000K produces a neutral white light that appears crisp and slightly cool without the harsh blue tint of higher color temperatures. It’s noticeably whiter than traditional warm 2700K-3000K residential lighting but not as sterile as 5000K-6500K daylight.

This color temperature provides excellent color rendering for security applications, making it easier to distinguish clothing colors, vehicle details, and facial features on camera footage. The neutral tone also complements most home exteriors without creating an overly commercial appearance.

No, both LED heads operate from a single electrical connection to your 120-volt junction box. The fixture’s internal wiring distributes power to both heads simultaneously through one power input.

This single-connection design simplifies installation and eliminates the need for additional wiring or circuits. Both heads activate together when the motion sensor triggers, providing coordinated illumination across your coverage area.
