Installed 4 of these in 3 different locations, 2 in the 1st location(side yard North) at 20 & 40 feet, and one each in location 2 & 3. I had to install 2 in location 1(side yard north) because one was not enough to illuminate the area near my back gate.
I ran 110 outlets in the attic to each location to power each illuminator. I'm really impressed with the build quality and price point of these illuminators. I also like that the power cable is routed through the mount, so no exposed cables. The brightness is not has bright as I hoped for (had to mount 2 at location 1) to get the illumination I wanted. The illuminator is adjustable, however not as easy to adjust as I hoped. The adjustment ring is hard to adjust. I had to put a small dab of silicone lubricant on the threads. One thing I noticed is that all 4 of my illuminators have the same SN..? The red leds are visible at night. Overall I am satisfied with my purchase. I have had these units for under a week with no issues, they come on automatically at dusk and off at dawn. I will update my review if I encounter any issues with these units.
FOLLOW-UP 12/3/2019 I have had these IR Illuminators for 5 months now. They have performed well. I do have one small issue to report I found one of the 9 IR LEDS was not working on the first IR Illuminator that I installed in July. Even with the one dark IR LED I saw no decrease in the illumination on my back fence.

I contacted Amazon and they gave me the email address to contact Tonton sales department. they replied back within 10 hours and are sending me out a replacement. ADDITIONALLY I have added another IR Illuminator in my backyard by my back door. You can view the before and after snapshots to see for yourself. I am raising Tonton from 4 stars to 5 stars because I am very pleased with the performance of these IR Illuminators and the warranty service

I just got these, so this is an initial reaction. I bought these specifically so that I could turn my CCTV camera's built-in IR LEDs off. The built-in lights were attracting orb weaver spiders which build their webs directly on the cameras every night. The spiders were attracted to the light, or the bugs that came toward the light, doesn't matter.

1) Light spectrum: The cameras are Reolink RLK8-810B4-A. They are definitely compatible in terms of the spectrum of light.
2) Light quality: The built-in LEDs on my cameras create a much more even and diffuse light across the camera's POV compared to these LONNKY illuminators, which are a bit more like a spotlight with soft edges. I wish they were more like the built-in lights.
3) Distance: LEDs have a more directional throw of light than you might expect, but I wouldn't say they would give clear light for your CCTV cams nearly as far as they claim. See my photos for an idea of the distance they will illuminate in practical application.
4) Build: They are very light weight, so not sure how sturdy they are. They turned kinda warm after being on for a short time, so I'm worried. We'll see.
5) Power source: I stupidly thought the DC connector on the CCTV camera was an output that would power these IR illuminators. Those DC plugs on my cameras were input only, so you will have to power these IR illuminators some other way. I will have to install electrical receptacles in at least 4 places to power these things.

I bought this so my tracking for my VR controllers will work better and I can play in the dark. Works great I would have given it five stars but it does only turn on in low light that's not a big deal for me. When I'm looking through Oculus quest 2 pass through it's like looking around in a sunny day it's awesome. It's definitely helped with the tracking of my controllers on every game I'm about to buy a second one to put on the other side of my room so I can be completely illuminated at all times. Which is definitely Overkill because this thing is bright. If you are serious VR gamer or want to make sure you don't lose tracking while playing beat saber or some other fast handed game get one of these. It will also help you from disturbing your loved ones with bright light late at night and help you save on electricity bill cuz you don't need to keep all the lights on to make sure you're tracking stays good.

Pros:
- Bright enough to make a difference.
- Looks good. Subtle, black, and fairly small. Not the studiest build, but good enough. I'd question it's water proofness although it doesn't matter to me.

Cons:
- Couldn't bend arm, so the straight-out bullet is all you get.

A note: See attachments of ON & OFF. The distant objects are a little darker with the light ON, because the camera adjusts for that light. It's only an issue when other lighting also exists, like this one. I'll re-position it 20' away instead of 6' so hopefully the near objects aren't as unevenly lighted; but this is true for any extra IR light.

I use Nest IQ outdoor cameras, and adding this IR illuminator made a significant improvement in what the camera sees at night. It does throw extra light an middle of the area it's directed towards giving it a sort of spotlight feel; however, it does illuminate the entire area where I can easily see what I couldn't before. We'll worth the money.
