I manage purchasing for a 70-person company with two office locations. That means I buy everything from printer toner to outdoor security lighting. When I took over in 2020, I learned fast that the cheapest option is rarely the cheapest option. But that's a story for another time.
In the fall of 2023, our landlord told us we'd be responsible for new exterior lighting at both locations (predictably, he did not offer to pay for any of it). The existing fixtures were old, dim, and half the motion sensors didn't work. So I speced out replacement options and kept landing on two approaches:
A dedicated LEDVANCE floodlight paired with Zigbee motion sensors.
Or a security camera with a built-in spotlight—specifically the Arlo Essential Spotlight Camera, since it kept showing up in every search.
I didn't set out to run a side-by-side test. It just happened. The main facility was a straightforward retrofit, so I installed the LEDVANCE floodlight with a Zigbee sensor at the parking lot entrance. The second facility was trickier—running new wire meant cutting through concrete, and the Arlo's battery-powered design promised easy installation. The upside was getting video coverage plus a light from one device. The risk was that a combo device would be mediocre at both jobs. I kept asking myself: is that convenience worth potentially subpar lighting and subpar video?
I bought both. Fourteen months later, here's the comparison I wish someone had spelled out for me.
How I Set Up the Comparison
I compared both approaches on four dimensions that actually matter for a small commercial facility: light output and coverage, reliability and day-to-day maintenance, smart integration and ecosystem fit, and total cost over three years. If you want a single verdict, there is one at the end. But the useful part is understanding which approach fits your situation.
Round 1: Light Output and Coverage
This is the most obvious dimension, and honestly, it's not close.
The LEDVANCE floodlight at our main facility is a 50W unit. I won't quote the advertised lumen count from memory because I'd probably get it wrong, but I can tell you what it looks like every night: the corner of the parking lot is evenly lit, and you can read a license plate from about 40 feet away. The Zigbee motion sensor picks people up before they reach the walkway, so the light comes on early enough to make a difference.
The Arlo Essential Spotlight Camera's built-in light is small. It pushes out a warm pool that covers maybe 10 to 12 feet around the camera. To be fair, that does help the camera capture color night vision—it genuinely improves video quality in the immediate area. But it does not light up a parking lot. The rest of the space stays dark.
My opinion: if the job is making people feel safe walking to their cars, the LEDVANCE floodlight wins this round without much contest. The overnight crew was the real test. They don't read spec sheets. They just know whether the parking lot feels safe when they walk out at 1 AM. Every one of them noticed the difference between the two locations.
Round 2: Reliability and Maintenance
Here's where I get on my soapbox.
A security light that doesn't turn on when someone walks by isn't an inconvenience. It's a liability.
The LEDVANCE floodlight has been rock solid for 14 months. No maintenance, no re-pairing, no surprises. The Zigbee sensor works every time. I do not mean "every time" in the marketing sense—I mean I've tested it by walking into the sensor's range at different hours, and it has turned on every single time.
The Arlo has needed more attention than I expected. Twice in the first six months, it dropped offline. The first time, restarting the app didn't help. The second time, I spent a solid evening Googling "how to factory reset Arlo Essential Spotlight Camera" and trying combinations of button holds, waiting for the LED to blink specific colors, and re-adding the device to the app. It came back eventually, but I lost a night of footage and a chunk of sanity.
Honestly, I'm not sure why it drops as often as it does. My best guess is the WiFi signal at that corner of the building is less stable than the camera needs. But that's kind of the point: a device that depends on WiFi, an app, a subscription, and a rechargeable battery has more ways to fail than a wired floodlight.
The way I see it, prevention over cure applies to buying decisions too. Five minutes of research before a purchase can save five days of fixing problems later. I didn't dig deep enough into Arlo's connectivity reputation, and it cost me an evening.
Round 3: Smart Ecosystem and Integration
I didn't expect the ecosystem angle to matter as much as it did. But after a year of running both, it's a real difference.
The LEDVANCE floodlight lives in the Smart+ ecosystem, and the Zigbee sensor communicates locally. That means the motion detection and light trigger work even when the internet goes down. We've had two outages in the past year—one planned maintenance, one storm-related. In both cases, the floodlight still came on when someone approached. The Arlo did not record anything during those windows.
The Arlo Essential is cloud-dependent for everything that makes it smart: alerts, recording, remote control. No WiFi means no camera. Simple as that.
Another thing that mattered: we already use LEDVANCE lighting inside the building. Their wall downlights are at the main entrance, and I've speced LEDVANCE downlight wall fixtures for stairwells in past jobs. The LED panels are throughout the offices. So adding the floodlight into the same ecosystem meant no new apps, no new vendor relationships, no new warranties to track. For a one-person purchasing department, that's more valuable than it sounds.
To be fair, the Arlo app is more polished than the LEDVANCE Smart+ app. It's a utility app versus a consumer app, if that makes sense. But the LEDVANCE app has never crashed on me, and the devices respond when I open it. I'll take functional and boring over flashy and flaky.
Round 4: What Both Approaches Actually Cost
Here's a rough breakdown from our actual invoices. I've rounded numbers for readability, but the ratios are real.
Location 1: LEDVANCE floodlight + Zigbee sensor
- One 50W floodlight and two Zigbee motion sensors: $180
- Electrician for half a day: $250
- Total: $430, one-time
Location 2: Two Arlo Essential Spotlight Cameras
- Two cameras: $380
- Cloud subscription for 14 months: $200 and counting
- Replacement rechargeable battery: $60
- Total: $640 and climbing
The Arlo setup has cost roughly 50% more in just 14 months, and the gap grows every month because of the subscription. And we still don't have adequately lit parking at that location.
One side note before I wrap this up: if you're comparing lighting vendors and their sustainability claims, the Federal Trade Commission's Green Guides (ftc.gov) are worth knowing. They set expectations for terms like "recyclable" and require environmental claims to be substantiated with evidence. It's a useful lens for separating marketing language from real specs. I've been burned by vague "eco-friendly" claims from other vendors before, so I read spec sheets carefully now.
Which One Should You Buy?
Here's my bottom line.
If your goal is to illuminate a space—a parking lot, a loading dock, a walkway—buy the LEDVANCE floodlight with a Zigbee sensor. Don't overthink it. It's a purpose-built device that does its job reliably, works with a broader ecosystem, and has no recurring costs.
If your goal is to capture video evidence, buy a dedicated security camera. The Arlo does that well. But don't expect its spotlight to replace a floodlight. It's a supplement, not a solution.
The combination I'd recommend for most small commercial facilities: a LEDVANCE floodlight with Zigbee motion sensing for the lighting, plus a proper security camera (with its own illumination for night vision) for the video. You'll spend more upfront than whichever single option is on sale, but each device will do its job better, and monthly subscription costs stay predictable.
I started this comparison half expecting to recommend the camera-spotlight for smaller sites like our second location. Fourteen months later, I've changed my mind. A combo device that does two jobs is rarely as good as two devices that each do one job well. Printers taught me that. The Arlo Essential Spotlight Camera reinforced it. And the LEDVANCE floodlight—the unglamorous, reliable, purpose-built option—has been doing its job every single night without asking for anything in return.
