Connected to 12Vdc, this one unit does an excellent job of illuminating my entire driveway apron and all the way across the road.
Note that if you get a lot of rain, you may need to beef things up a bit by having more illuminators -wet surfaces soak up a lot of 850nm IR.
I knocked off one star only because the vendor does not offer the mating connector for the tiny power socket on the illuminator board.

I was impressed with how bright these are and ordered 2 more.Angle may be a bit tighter than 60 degrees.
It does have reverse polarity protection (found out by accident).
Best Deals for Gino CCD CCTV Camera 5mm 48-LED Lamp 60 Degree IR Infrared Board
The ability to make IR LEDs only requires the omission of phosphorous during the making. Meaning they are cheaper to make than the white LEDs. So one should use 940 nm LEDs instead of 850nm LEDs. 850 nm Leds are good for a deterrent but they also give away the cameras location. Any red LED light bulb will do the same thing getting the criminal to avoid that position. Only the invisible LED lights assist in apprehension once a crime is committed. 850nm emmits a red light, while 940nm emits a light the human eye cannot see, but the camera can. Also UV or black light bulbs are just as effective as 850nm red IR lights.Honest reviews on Gino CCD CCTV Camera 5mm 48-LED Lamp 60 Degree IR Infrared Board

These are great for hobbyist that have a little bit of electronic experience. The reason I say that is because they don't come with a plug to hook them up.So you either have to try and locate a plug on line or do as I did and remove the plastic socket and directly solder the wires to the board.
It's fairly simple you only need a positive wire and a ground to go to the board the day/night sensor is built in. I have ran mine on any thing from about 9 volts to 12 you should have about a 300 Ma supply or better to run it on.
Some reviewer have said they ordered plugs that work I just opted to hard wire mine.
With that out of the way these are great for many applications I am using mine as auxiliary lighting for my security cameras. They do illuminate an area well,one reviewer complained they don't work well I think the issue is his camera. I have several security cameras with ir lighting and the ir rings work great with them. I have fully illuminated my whole yard and key areas in my front yard. I have some other cameras that didn't have lights on them but do work with the ir leds but the cameras are not as sensitive to the ir light no fault of the led ring. These are much cheaper alternative to buying ir illuminators already assembled. One other thing to mention you will detect a low red glow from these as with most ir leds. So if your expecting these to be completely undetectable there not. All of my cameras have the tell tale red glow too as part of the ir light bleeds into the viable spectrum.
What I found to work for me with the 48 led rings is to use old spray paint can tops. the ring fits fairly well inside the cap. To secure the ring in the cap I sanded the plastic inside the cap a bit to roughen it up and used epoxy to secure it in. Before doing this tho I have drilled a hole at what will be the bottom of the cap to allow any water that may get in out. On the back of the cap I have drilled a hole to fit one of the cheap camera mounts I got off ebay with a stud that would screw into the bottom of the camera and used it to attach the spay cap and sealed it with some silicone. I would back the nut up with a washer to prevent the pressure of the nut from cracking the plastic. also don't forget to drill a hole for your power lead into the cap and seal it also.
I have no lens cover over the front of the unit but at the angle they sit not expecting to get much water in them at all. Maybe some one will get an idea for a front lens cover.
If your using them inside you won't need to go through all the trouble to make it weather resistant.
I hope this review helps give you some ideas on a housing for your new IR rings I have ordered over 8 of these and the vendor is great too I had a minor issue and they made it right and than some.
