240-Degree Replacement Motion Detector, Adjustable Time & Detection Sensitivity Up to 60 Feet Range, 3 Working Modes PIR Motion Sensor for Security Floodlight, White, UL Listed
Quick take
This replacement PIR motion detector is designed to revive an existing security floodlight fixture without replacing the whole unit. It offers a 240° detection angle, up to 60 feet of range, and adjustable timer and sensitivity plus three operating modes (Auto, D2D, and manual override). The main buying caveat is that it must match your fixture and load requirements to work safely and correctly.
Pros and cons
Pros
- Three modes for different light-on behavior (Auto, D2D night-only, and manual override).
- Stepless adjustable timer from 10 seconds to 10 minutes and adjustable sensing sensitivity, with a claimed up to 60 ft range.
- Rotable, adjustable sensor head to aim coverage where you need it (up to 300° horizontally, 180° vertically).
- Built for replacement use, aiming to be quicker than swapping an entire fixture.
Cons
- Replacement parts still require correct wiring and compatibility with your existing fixture’s design.
- Load limits apply (max 300W incandescent, or max 72W LED driver/LED bulbs), so it may not fit every bulb setup.
- Coverage depends on placement and settings, so results can vary if the sensor is aimed poorly.
- Review evidence is mixed on longevity under heavy moisture events (one report), so outdoor placement still matters.
What buyers think
Buyer-review evidence is fairly limited, but the recurring themes are positive around ease of installation and day-to-day performance. Multiple shoppers describe the sensor as “easy to install” and that it “works as advertised,” including lighting up when approaching a door or driveway. For value, buyers appear to like the idea of repairing an older motion sensor spotlight rather than buying a pricier full fixture replacement. That said, there is at least one durability-related concern tied to a heavy rain event and visible water intrusion, and another review raises frustration about support and troubleshooting. Overall sentiment trends toward functional replacement value, but the longevity and support experience may vary depending on installation and conditions.
How the 3 motion sensor modes work
This sensor includes three working modes that control when the light turns on, and how it behaves after motion is detected:
- Auto Mode: When movement is detected in darkness, the light turns on, then turns off after a programmable delay (set on the TIMER control).
- D2D Mode: Night-only behavior, where the sensor works at night and stays off during the day.
- Manual Override Mode: Allows manual control, with the light staying on for up to 8 hours and automatically turning off at dawn.
If your goal is fewer unwanted daytime activations, D2D Mode is typically the better starting point. If you want consistent night activation after motion, Auto Mode plus the timer adjustment is the usual fit.
Coverage, range, and aiming flexibility
It uses a PIR motion sensing approach with a 240° detection range and a claimed sensing reach up to 60 feet. Coverage is not just about the numbers, though. The adjustable sensor head helps you direct detection across the area you care about:
- Vertical adjustment: up to 180°
- Horizontal adjustment: up to 300°
For best results, mount and aim it so the sensor “sees” walk paths rather than directly watching shifting foliage or surfaces that can move or reflect heat.
Adjustable time and sensitivity (and what to set first)
The TIMER control lets you set the delay from 10 seconds to 10 minutes. Sensitivity is adjustable as well, allowing you to tune how easily motion triggers the light. A practical approach is to start with moderate sensitivity and a shorter timer, then adjust based on your typical approach speed and how long people linger near the entryway or driveway.
If you experience frequent false triggers, lowering sensitivity and improving sensor aiming often helps before changing everything else.
Replacement fit and load limits
This unit is intended to replace the motion detector component for compatible floodlight fixtures. It’s designed for wiring installation with wire nuts included. It also specifies load limits you should match:
- Max incandescent load: 300W
- Max LED driver / LED bulbs load: 72W
Make sure your existing light fixture’s bulbs or driver wattage stay within those limits, and verify the wiring and mounting approach are compatible with your fixture. If you need a simple “swap it and forget it” upgrade, check compatibility first to avoid spending time on troubleshooting.
Installation and setup reality check
Several buyers report installation taking around the same order of magnitude you’d expect for a replacement part, and that it worked once wired and aimed correctly. Even so, setup still matters. Most real-world performance issues typically come down to:
- Sensor placement and aiming (coverage misses or too much coverage).
- Timer and sensitivity settings that do not match your environment.
- Fixture electrical compatibility and load limits.
If your current setup is hard to reach or involves unusual wiring, it can be worth comparing this replacement approach to swapping the entire fixture for a more integrated solution.
Pros and cons for different buyers
Best for
- Homeowners who want a budget-friendly replacement for a failed outdoor motion sensor within an existing floodlight setup.
- People who want wider aiming control (240° detection plus adjustable head) for doors, driveways, garages, or walkways.
- Shoppers who like customizing behavior using timer, sensitivity, and mode selection.
Not ideal for
- Buyers who cannot confirm electrical and wiring compatibility with their current fixture.
- Anyone using an LED setup above the stated max LED load (72W for LED driver/LED bulbs).
- Situations where the sensor may be exposed to direct water pooling or heavy moisture without protection, since outdoor reliability can depend on installation conditions.
Alternatives to consider
If you are replacing the motion capability but do not want to verify wiring and load limits on a replacement sensor unit, an integrated motion light (complete fixture) can reduce compatibility uncertainty. Conversely, if your goal is keep your existing fixture but still need improved aiming and control, a replacement sensor with adjustable head and multiple modes like this can be a practical middle-ground.
Verdict
The 240° replacement motion detector is a solid choice for shoppers repairing an existing security floodlight fixture, especially if you want adjustable timer, sensitivity, and flexible sensor aiming. It looks particularly well-suited for entryways and approach paths where you can aim coverage carefully. Just confirm compatibility and wattage limits for your light setup, then expect real-world performance to depend on where and how you mount and tune the sensor.
Price and availability
It is listed as in stock in the U.S., and you can check the latest pricing on the product page. Because replacement parts can fluctuate, it’s worth confirming the current total cost before ordering.
FAQ
Is this motion detector a replacement for a floodlight fixture?
Yes. It’s designed as a replacement motion detector unit intended to be wired into compatible existing motion-sensor floodlight setups, so you do not necessarily have to replace the entire fixture.
What are the three working modes?
The sensor includes Auto Mode (motion triggers in darkness, then turns off after the timer), D2D Mode (night-only operation), and Manual Override Mode (manual on behavior with an auto shutoff at dawn after up to 8 hours).
How far and how wide does it detect motion?
It has a claimed detection range up to 60 feet and a 240° detection coverage angle. Actual performance can vary based on placement, aiming, and your environment.
Can you adjust the timer and sensitivity?
Yes. The TIMER control adjusts the delay from 10 seconds to 10 minutes, and sensitivity is adjustable so you can tune how easily motion triggers the light.
What wattage limits does it support?
It specifies a maximum of 300W for incandescent lamps, and a maximum of 72W for LED driver or LED bulbs. Your light setup should stay within those limits.
Does it include a battery?
No. It is listed as a corded electric motion detector with battery description indicating battery not included.
What should I check before buying for an existing setup?
Confirm wiring compatibility, mounting fit, and that your bulb or driver wattage is within the stated load limits for incandescent and LED.
Does it work in cold or hot temperatures?
It lists an operating temperature of 122°F. If your location regularly exceeds that, you should confirm suitability before relying on it.
