## Description

desertcart.com : Tendelux DI20B IR Illuminator | Long Range Infrared Flood Light for Security Camera (Black, w/Power Adapter) : Electronics

Review: Works well, but is visable to the naked eye - Used this product to illuminate an outdoor PTZ camera. It's small, lightweight, and compact. It's NOT invisible at night to the naked eye, as the LED's on the device do have a red glow to them. The resultant IR light is good. I found that I can illuminate a larger area by bouncing the IR light off of an exterior wall and onto the surrounding area. This allows me to make the area close to the building highly visible, while giving sufficient illumination to the surrounding area. By facing the sensor toward the wall, the red glow immigrating from the LED's was not visible from street. I purchased the 30 ft cord, because the sensor was a distance from an electrical outlet. There was a small piece of heat shrink tubing included (with no instructions). I used this and a heat gun to help make the connection between the device and the extension a bit more water resistant. When using the extension, there are actually two connections, so I used an additional piece of heat shrink that I had laying around the house for the other connection. The hardware to install the device was included and there is an adjustable gimble that allows you to pretty-much adjust the angle any way you want. The devices works great and is inexpensive. Hopefully it will hold-up in the long run.
Review: Durability and quality - Installed 1 Dec 2023 and is a well-made solid product. It comes well packaged and with sufficient installation accessories. Installation was simple and additional cable can be purchased if needed. Using it for a WYZE V3 and it worked great. Nighttime illumination of the yard was good but it quit working witin 60 days. I checked the transformer output and it was in specs. Power is traceable to the unit but it does not generate any IR Illumation. I verified this with a military-grade IR light wavelength identifier. Additionally, the unit reads ambient temperature on the scanner (no Heat at all). Not sure if this is a random QC issue or not. Update: the seller contacted me and offered and shipped a replacement for the IR illuminator. He was very open with my issues and the company is definitely customer service oriented. I updated my rating to 4 and my current feeling is this is a random isolated issues with this product. I will follow up after using the replacement IR illuminator. Update #2 I have updated my review to a 5. The replacement illuminator has performed flawlessly and I definitely would purchase another unit from Tendelux. Thank you Tendelux for a great product and customer service. Update #3 30 March 2025 The replacement illuminator continues to perform flawlessly. This is definitely a quality product and seller. I would recommend this seller and product.

## Features

- Unbelievably Compact and Powerful - Based on our customers' needs on small-sized infrared illuminators for their long range applications, Tendelux nailed it. DI20B is only 1/2 the size of BI18 (our 18W model) and yet provides more illumination for your CCTV cameras to obtain crystal clear images at night.
- Redefining "Even Illumination" - With the tailored design integrated lens, the IR lights are more efficiently and evenly spread on your camera's field of view. No more "hot-spot" and washed-out pictures.
- EASY Angle Adjustment - With the new style mounting 360-degree swivel and 90 degree tilting bracket, now you no longer have the trouble in adjusting the lighting angle horizontally. It's also made of premium aluminum which doesn't age rapidly under the sun like these plastic types.
- Sleek look & Effective Cooling System - The DI20B infrared light features a unibody design which is a combination of an effective cooling system and an especially modern styling, ensuring stability and tightness, making it a sweeter match with your camera. The specially created housing guarantees the long working life of the unit.
- What You Get - 1x DI20B Infrared Illuminator (Black) with 360-degree adjustable stand, 1x 110-240V AC to 24V DC 1.5A power adapter, installation screws, 1x user manual, 18-month warranty, and lifetime friendly support from Tendelux.

## Questions & Answers

**Q: Does this turn off during day time?**
A: Hi Sir / Ma'am,

The illuminator has this photocell sensor that detects ambient light, it controls the light to turn on when it's dark (less than 20 lux) and turn off when it's bright.

 
The photocell is located at the back of the lamp, the small round spot near where the cable comes out. If you need to keep the light on, you may use a black tape to cover the photocell.

Please just let us know if there's anything we can do to help. Much appreciated.

Best regards,
Tendelux Support

### ⭐⭐⭐⭐ PsychosocialCCTV :) I have lots of these in most brands available. WISH THEY THREW THE IR FURTHER!
*by P***V on June 25, 2025*

I wish i could give 3.5 stars. Sorry, no pics. I have so many IRs it would be impossible to determine which one is doing what. OK so I have a LOT of Cameras!!! Last count was TWO 32 camera CCTV setups, an 8 camera setup, and a 12 camera setup. (Not including individuals) I have LOTS of IR illuminators as well. So build quality gets a strong 3. NOT THAT IMPRESSED. Not that they aren't rugged, it's just that most of the time I have to either add angled bases (that pivot) or I have to extend the illuminators to their absolute limit in one particular direction. They insinuate that they are easily adjusted in any direction, but trust me here, that is NOT the case. In reality the illuminators are VERY difficult to angle (once past minor angles) due to the slip channel design. That makes me nervous. I wish I could just mount them like you see on the pics, and point them straight, or down a little, or up a little, but real world isn't as easy. Because of this I get worried that they will break first time some large bird perches on them, and owning a berry farm, we get LOTS of birds!!! In their "normal" angles, they would get a 5 for build quality, but rarely do I ever get off that lucky that I can use straight on lighting. Light output. OK lets get the huge elephant out of the room. They do NOT light as far as they say. NOT EVEN CLOSE!!!! But having used all the major brands of IR Illuminators, I can say NONE of them do. I'm getting a decent lighting coverage at 60-75 feet away. Thats a REALLY GOOD wide path of light Id estimate at around 60 feet wide. Any further than that and it gets a LOT weaker with every extra foot. Yes they work, and I order these because they are the brightest on amazon, but I'm still not impressed. WE NEED MORE LIGHT OUTPUT!!! Id gladly pay twice the price I paid for this light if they would make an illuminator with 3 times the light output, with an emphasis on LONG THROW pattern. I don't need wider; I need further away. So with these 2 huge negatives, why the 4-star review? Because at the current moment these are as good as I have been able to find. AGAIN, I'm not really impressed. Kinda an "I guess that will have to do... just disappointing". Theres another one out there that makes an IR that comes in a big square box with larger LEDS, and it does a LOT better on long throw IR, but its not as good at wide coverage.. This brand does really well with wide areas relatively close to the camera. Yes, they're water resistant. 5 stars there. Cord is TOO SMALL!!! If you can go through a wall, you're OK. One of mine (exact same camera actually, bought 3 years ago) is mounted on the outside of my vintage RV. No worries with the cord on that one, but one of these I had to wire completely outside by drop-cord, and that makes me VERY nervous. I don't expect that camera's cord to last more than a couple years at best. The price is just OK, A bit overpriced, and I'd much rather pay say... 500 to buy one REAL IR illuminator (something like the sports arenas have) than 8-12 of these, but at the current time these are all I can find. I like my property heavily lit up on monitors, and thieves spotted quickly. Meh... They kinda do the job.
