Review on L Shape 4-Pin LED Connectors 10-Pack: Expand and Customize Your Lighting with JACKYLED 10mm Wide Right Angle Corner Solderless Adapter Connector Terminal Extension, featuring 22Pcs Clip Connectors for 3528/5050 SMD RGB 4 Conductor LED Light Strips by David Miller

5 stars for the price, clean installation. and if you only need a 90 degree connection (left or right). These L-shaped connectors ensure a clean installation. Photo-B shows the final installation on the LED strip. If you need an angle other than a straight 90 degree, a wired connection may be better for you. These L-shaped connectors have two locking pins to prevent the strip from being pulled out, resulting in a more secure connection. Other brands simply apply pressure to the pins to secure the strip in the connector. Also note that they can be used as a direct connector by inserting an LED strip at either end of the connector without using the L-Connect PCB. 15% of reviewers seem to have bad connection issues with broken bars, cross color, or not all lights after connecting everything. After using them and having a bad connection initially, I looked to see what could be wrong. Then I realized that this isn't just a process of cutting, inserting, and snapping a connector. This will work every time. You have to take the time to get it right. I found it much easier to set up and test all connections prior to installation. Check each connection when adding a track. When designing a room, build one corner at a time and test them before sticking them to the wall. After cutting along the appropriate cut line on the strip, remove the self-adhesive foam backing from the backing under the copper strips, about ¼ inch. . (Photo-1). You should end up with a very thin strip to insert into the connector. The connector has a thin slot at the end into which a strip is inserted (Photo-2). The end of the tape is not pushed into the pins from above. When inserting into the slot, press on the copper strips that go under the 4 pressure contacts. This may seem simple, but I noticed that when pressed, a contact can go up instead of down. Photo 3 shows the bottom connector from below and does not provide proper contact. After making sure all 4 copper strips are under the pressure contacts on the connector, wiggle them to make good contact and make sure they are fully inserted. Insert the L connector PCB (check the connection) and do the same for the connector on the other end. Make sure the (+) side of the strips are connected. Do not click until the connection has been verified. What you need to check for a good connection. 1) The tape is inserted under the lip. 2) The copper on the band is under the push pin and fully inserted. Wiggle to ensure a good connection 3) Do the same for the L connector PCB 4) (+) aligned towards the end 5) Apply power and ensure all indicators are working before snapping 6) If the connection works, snap in place, I also use pliers and I press lightly to ensure the two pins are inserted into the strip to hold it in place. Photo 4 is a photo of the correct connection and the area to check. I don't quite understand the right and left corners in the "Ratings and Questions" section. Photo-6 shows how the connector is used at an angle on the right and left. Some complain about labels on the L-Board being in reverse or RGB format or in a different order and therefore unusable. As long as you keep the LED strip connectors (+) on the strip that connects the (+) connectors to the LED strip on the other side, the RGB will stay aligned regardless of the markings on the L-PCB. See photo-7. This shows that the LED strips (+), R, G, B are aligned regardless of the connector markings. These are direct connections. If you align the ends of the LED strips in the same order so that the (+) lines are up or the top is down, the rest of the strip will fit. (photo-7)
