Seems like a great product until your done. I installed 4 of these connection at each corner to make a square, for tv bias lighting "square of LED's for behind the" Once done I noticed after each connection the LED's got dimmer and dimmer. I tried swapping them out with new ones. Nothing changed. I have worked in electronics and wiring for years. This product is not of quality. I hope Amazon has another solution. The obvious issue with these connectors is they are causeing to much resistance. Each connection would add enough resistance to drop the light output on my 117" long strip light. At each corner getting worse. Do not buy these if you care about even led output.
The connector pins do the job but it take a bit of patience in order to get the results you want. When I first installed them on my lights, one side the lights wouldn't work, green or blue wouldn't light. It was part my fault and the design doesn't help also, but you can make them work. Here are tips on what will help you make them work. (1) After you insert the right angle strips to the connector clips, I'd advise that you use a multimeter to check continuity before attaching them to your LED lights. At my first attempt I didn't do this ,I dinnt have the strip pushed underneath the pin far enough and it wasn't making contact. Second time around I did and it was fine. I used my multimeter meter to confirm. (2) You will need to bend the pins up slightly with a small screwdriver in order to get the strips and the led light strips under the pins as the pins are tight. When you have the strips under the pins just push them back down with your screwdriver and then clip them into place. I used LED strips with the silicone so I had to peel that off. Overall, its is tedious but they do work. You just have to make sure the pins make proper contact with the LED copper strips. Hope this helps.
I'm sorry to say but I regret buying these. When I first got my LED strips, I mock set them up with tape to the inside of my display cabinet and it looks really nice. I quickly realized that it order to properly adhere the LED strips to the inside of the case that I'd have to navigate the 90 degree corners and that I'd need some clips like these.
I got them quickly the next day but unfortunately when I installed them, some of the connections were very hard to do properly. When you cut the LED strips on the cut lines and remove the backing (to stick the strips on the surface) it is very difficult to slide the LED strips all the way into the connector.
As a result, half of my lights were the selected colour I wanted but the other half would be a different colour than the one selected (or on some colour settings not work at all) both of which looked terrible in my display case.
I ended up removing and ordering another another set of strips and taped them up as one continuous piece my original strips were cut to be connected and no longer were long enough as one continuous strip.
Overall, these connectors were a waste of my time trying to set them up as well as the money spent on them and the replacement LED strips.
I should have just settled with taping the lights up with no connectors in the first place as I'd have been better off.
These L Shape 4 Pins connectors are great for creating right angles with your LED strips. The metal connectors are securely tight, making it difficult to slide your LED strips in them. There really is no way around this but to manually loosen the metal connector pins or make sure the ends of your strips are stiff enough to slide beneath the connectors. The L-Shape Pins included are strong and can hold its shape. Over this is not the most easy task but its doable to create flush right angles for the perfect aesthetic look on your LED strip set up!
5 of the 90 degree adaptors had breaks in them. 3 wouldn't display green. Checked with my meter and the line was broken. The other 2 either red or blue was effected. Also noticed some of the clips are the slightest bit off alignment to the strip lights. Sometimes causing 2 colors to short out. Others don't have the same issue. It's not a matter off alignment or adjustment the copper contactors are physically off.
I had two different strips from 2 different manufacturers. One of them fit perfectly and easily. The other strip was a bit of an issue to insert into these. I ended up pulling the pins with tweezers so it rests a bit higher, inserted the strip in then pushed down the pins. Not sure why there was an adhesion rating, these do not have adhesive with them unless you mount it with a screw.
it's really hard to slip the light's cable between the clips without damaging the copper ribbon cable. It would be better if you could pry apart the clips prior to snapping them shut, but you can't, really. They work, but after just a few months the RGB stopped connecting properly, so now after the second joint I had, the colour changes. I could have fixed it, but I super-glued the lights in place.
My recommendation if you're buying this product: be VERY gentle and have a lot of patience.
The L shaped strips included in the product do not slide in effortlessly in some of the connectors and you are forced to bend the pins which break VERY EASILY. I had so much trouble bending the pins in the right angle to get all 3 colors working.
This worked perfectly for setting lights up on my tv. The only thing to make sure is that you put the lights in the right way or they won’t work. I found out the lights have to go in a specific direction. So when I first put them together only one section of lights worked. But I took the lights out and flips them around and it seemed to fix the problem. If it doesn’t work the first time it’s probably not the clips messing up. It is the direction you have your light strips
