I have had two of these working in temperatures from -35 to +35 C since purchase in 2018. Much better than the built-in night vision.

Man erhält hier einen wunderbaren, kleinen, unauffälligen IR-Strahler, der das Nachtsicht Bild der IP-Kamera deutlich aufwertet zu einem wirklich günstigen Preis. Ich habe den Strahler nun seit bald drei Monaten im Außenbereich, direkt der Witterung (Minustemperaturen, Schnee, Regen,...) ausgesetzt, im Einsatz und bisher funktioniert alles zu meiner Zufriedenheit.Das metallische Gehäuse ist robust gebaut, bisher wasserdicht, die Installation ist aufgrund des geringen Gewichts einfach mit einer Schraube zu erledigen.Der Strahler lässt sich dann noch sehr gut in der Position einstellen, das braucht man auch, denn die Ausleuchtung ist relativ punktuell. Aber das kommt natürlich auf den jeweiligen Anwendungsfall an, ich jedenfalls bin zufrieden. Bei mir wird in ca. 15m Entfernung nun alles ordentlich erhellt was bisher nur ein dunkler Fleck war im Video.Der Dämmerungssensor funktioniert zuverlässig, der Strahler geht immer etwa zeitgleich mit dem Kamera-IR an und auch zwischendrin aus, wenn die Lampe vor der Tür angeht, es also "hell genug" ist.Fazit: Ausleuchtung sehr gut, einfache Installation, klein und unauffällig, und bei dem geringen Preis kann man nichts falsch machen, selbst wenn er nicht ewig hält.

Buen alcance de luz, ayudo mucho en la visión nocturna. Pongo 3 estrellas ya que la publicidad es engañosa, no son 4 piezas (lamparas), son 4 leds, compre 2 pensando que iban a llegar 8.

These units provide a high level of illumination, and a useful range of at least 65ft. They are more effective than the 36-LED and 48-LED illuminators, in both respects - although their housings are larger (possibly making them more difficult and/or more conspicuous to use in certain spaces). The only potential downsides of these illuminators are the difficulty of installation (shared by *all* illuminators having this physical design), and slightly uneven illumination across the illuminated area.The installation difficulty is due to having to dismount the unit from its bracket in order to install the single center mounting screw into the mounting surface, and then having to re-mount the unit onto the bracket, by re-installing the two small side screws. This imposes risk of dropping (and losing) one or both screws, and the risk of losing one's balance on the ladder (because both hands are needed to re-install the unit using the side screws). As mentioned, this issue exists with *all* illuminators that have this type of mounting bracket. I avoid the problem by pre-mounting the entire assembly onto a common mending plate or angle bracket (typically available at hardware stores and home centers), and then using a magnetic-tipped power driver and a suitable screw or two to attach the assembly to the desired mounting surface.Although this unit provides fairly even lighting across its entire illumination area, it does have slight "hot spots". If hot spots are an issue for your application, use of a similar diffused ("no hot spots") illuminator could provide more even lighting, although probably at the cost of dimmer maximum illumination level and reduced effective range. However, I think that the increased range and maximum intensity offered by this unit would be preferable in most situations.I did have one of these illuminators fail a few weeks after it was installed. There was no apparent explanation for the failure, but the seller promptly replaced the failed unit upon notification. I have several other of these units that have been in continuous operation for at least several months without problems, so I think the failure was an exception, and probably not due to any inherent unreliability in this model.Overall, I am very pleased with these illuminators.

I actually have bought 2 of these. I used it for therapeutic purposes... This is a very strong light (although invisible to the naked eye, it can be seen with an iPhone or Android camera). I wouldn't recommend using it to others for therapeutic purposes unless you know what you're doing, and have educated yourself very well on the subject. You could actually end up hurting yourself if you leave it on one spot for too long.In order to use it therapeutically, I took black electrical tape and covered the light sensor in the middle. This seemed to do the trick for the most part. Also, I use it in a relatively dim lit room, with the two of them together, it keeps the light on. Nuff said on that topic...The only problem I had with this product is the first one I had purchased, the cord came somewhat loose from the back and it stopped working. I am sure this wouldn't have happened if someone was using it as a security camera or the like, and I believed this occurred because I was constantly moving around the light, and it was being pulled on often, which isn't its intended purpose. But I did dock it one star because it stopped working. The second one I purchased I am being much more gentle with, and so far so good.

Cette lampe fonctionne parfaitement. En cas de lumière elle s’éteint automatiquement grâce à son détecteur. Sa puissance lumineuse infrarouge est forte et permet d’éclairer correctement une pièce ou une zone extérieure. La finition est de bonne qualité. Lampe parfaite, je vous la recommande.

Very impressive, and under $12. I really didn't have high expectations, just hoped to fill in some of the dark areas my cameras IR wasn't reaching. These little lights did that, and so much more. I order 4, but have only installed 2. I could use a 2nd in the backyard, and it would almost clear as day time, in black & white, of course. As is, I can see movement, and tell if it's the dog, a cat, or opossum (to send the dog out after). Can't attest to how long these will last, or waterproofing (no rain yet). Kind expect that some water will get in through the two screw holes on the sides. Going to put some silicone or teflon goo on the screws, and should be good, maybe see what sort of seal we have on the front cover.The light I put shining down my front driveway turns off occasionally, may need to move it some. Seems that my motion activated lights are the cause, which aren't bright enough to help the cameras, but just enough to fool the IR light. Good to know that these shut off in the daytime, and not running 24/7, another unexpected bonus feature. Would have been nice if they had include some specifications. Not sure how much power these use, and my system is on a UPC, battery only lasts 20 minutes, with monitor on. Mostly, the battery backup, is just to keep the power stable, and short blackout/brownouts, that come during thunderstorms, which isn't good for electronics, bad for recording.I don't see any reason why these won't last for a while, they don't seem to run hot, didn't even feel warm the first couple of nights, when I adjusted the direction a few times, just to see what I could get out of them. I don't know about measuring the exact range of effectiveness, but from my back porch, where on is mounted, it lights up most of the yard, all the way to the fence, 50 feet or so away. Buildings across the ally seem better defined as well. Driveway in front is very brightly lit, 25-30 feet. Street lights haven't worked since Hurricane Irma, but still had that dark area next to my carport.Aside from my waterproof concerns, these are solid, well made, very good value. Case and mount are metal, glass cover seems thick. Cable is thick, seems like good quality as well, hopeful holds up to Florida sun, which is kind of rough on insulation. Money well spent, and would buy a couple more, when I find a good deal on another 16 channel DVR (had do downgrade to 8, after the last one died).

La uso da una settimana con ottimo risultato. Il fascio luminoso è piuttosto concentrato e abbastanza forte da illuminare bene almeno una quindicina di metri. Avevo però bisogno di una maggior diffusione della luce, dovendo illuminare diffusamente un'area inferiore ai 10 metri, per il videocitofono. Ho semplicemente svitato il la parte anteriore che contiene il vetro esterno e ho messo al suo interno una carta velina, preventivamente ritagliata a cerchio, in modo che la luce emessa dai diodi passi attraverso di essa. Questa piccolissima operazione mi ha permesso di illuminare tutta la scena in modo ottimale.Le due foto sono a dimostrazione di quanto detto. Si tenga presente che nella seconda, per via della minore intensità della luce IR concentrata, provoca anche una maggior apertura dell'obbiettivo per cui l'immagine risulta tutta più ricca di dettagli.Aggiornamento: dopo 6 mesi di utilizzo continuo, l'illuminatore funziona ancora perfettamente.
