BASIC REVIEW:- I bought the XL size (13.1 feet) for my 55" TCL 55P605 (2017 Best Buy version of the TV) and holy wow did it fit perfectly. I tried not to get my hopes up that it would be complete coverage until I had completely laid it out and taped it to the back of my TV with painter's tape, then I got stoked. It was so perfect, see pictures.- Squiggly ribbon geometry on the LED strip makes folding those perfect 90 deg corners much easier if you fold it at the biggest squiggliest part.- Brightness is good enough for me and color choices are also good enough. I plan to leave it on the soft white preset color, top right color on the remote. Next best color is the light orange color. I kind of wish there was another, darker orange between the light orange and the deep red.- Remote is RF so you don't need line-of-sight to make it work and your IR TV remote won't mess with it. Pro tip, keep the little plastic strip that blocks the battery contact and put it back in when you're not using the remote so the battery doesn't drain. Color the end of it red with a sharpie so you don't lose it when it's out.- In-line controls are a bit fiddly to get to on the back of the TV but it helps if you stick the controller in place with some 3M VHB tape. Read the instructions to figure out how to control all the modes and brightness with just the 3 buttons.- Gets 5 stars for now, hopefully this product lasts a long time since the fit and appearance is basically perfect on my TV. If it fails prematurely I will update this review.IN-DEPTH/TV-SPECIFIC REVIEW:- This product has the 5050 LED chips, which are the larger combined elements that each contain smaller R/G/B LEDs, opposed to the older 3528 style which has separate elements on the strip for each color. The 5050 chips on this strip give nice uniform colors and none of that annoying color shadow effect. The strip itself is white and the elements are bare (i.e. NO silicone covering) but that allows you to fold the corners neatly into 90 deg angles.- There are a few different folding options for making 90-deg corners. If you are careful to fold the correct direction you can make sure that the nearest LED element to the corner ends up on TOP of the stack and therefore avoids casting shadows on the wall. I got really lucky and all 4 corners of my TV ended up with an LED almost exactly in the corner so the backlight coverage is amazing and a complete border. I didn't stick the strip all the way down in 2 corners so that the LED would face straight back instead of angled in towards the middle of the TV (see pics).- For installation, this TCL 55P605 had a border along both sides and the top that was perfectly the width of this LED strip... like they were made for each other. Along the bottom was less perfect and required some bridging up and over a few protruding sections but it came out fine (see pics).- The strip ends overlapped by about one 3" section, which I decided to leave on instead of cutting off. Can't notice any brighter spot from the front so I will leave it.- Use some double-sided tape to hold the in-line controller to the back of the TV and keep it from drooping and twisting off the LED strip.- If you are curious about whether this TCL TV can power this strip, which claims to need 5V/1A in the setup sheet (although it clearly says 5V/0.8A on the packaging), it absolutely can. TCL does NOT give a max power rating to their USB ports, but it powers this XL LED strip just as bright as plugging it into a USB wall adapter.- I also use a chromecast (original 720p version, I know it's old) that came with a wall adapter that outputs a max of 850mA (although it probably doesn't draw much more than like 500-600mA). I previously had this plugged into the TV's only USB port so that it turns off with the TV and doesn't stay on all the time, heating the electronics 24/7. I experimented with using a USB splitter to allow both the Luminoodle LED strip and the chromecast to draw power from my TV's single USB port and... it worked. Lights don't seem any dimmer with the Chromecast plugged in and streaming, and the chromecast works fine with no issues.- At max I am drawing 1.85A through that single USB port, which seems like a lot for a TV port unless it's rated to run a HDD or something in which case it might be rated to 1.5-2.0A, but again TCL doesn't specify the power rating. I'm guessing the LED strip is only drawing 0.8A per the packaging (they say you need a 1.0A rated port, but most products only draw ~80% of the rated port for safety) and the chromecast is probably drawing about 0.6A max when streaming for a total of 1.4A, which seems like a reasonable load the TV should be able to handle. I don't use the chromecast all that often since the TV has a Roku built in but I will leave them both plugged in and see if any issues arise. Hopefully that only USB port doesn't get fried...COMPARISON TO OTHER PRODUCTS- I went back and forth between this product and one of the others with 4 pre-cut strips but eventually decided to get this one with the one long strip that would require corner folding and/or end cutting with hopes that I could buy a larger size and get full edge coverage on my 55" TV. The chances of getting an absolutely perfect corner-to-corner coverage with any pre-cut strip package seemed quite low, and those kits had several wires to deal with instead of just the one with this kit. Long story short, this Luminoodle product worked out perfectly for my 55" TV.- If you have a TV larger than a 55", you might be able to get a full rectangle of coverage with the XL size of this product but you will definitely need to offset the lights in from the edge of the TV by several inches, which will give you a dimmer backlight appearance. For any 55" TV this should be able to give you pretty much perfect edge coverage, depending on how thick the bezels are, but make sure to lay it out and fold it gently before actually sticking it on for keeps. This product still seems like it's the most flexible and will give you the best chance of making a custom setup for your TV, regardless of size, opposed to any pre-cut package.- The one benefit of the pre-cut strips featured on some other products is that they can be the waterproof version of the LED strip encased in a continuous silicone bead which is not necessarily beneficial for waterproofness when mounted on a TV but those strips also tend to be more durable since you can't break off any of the electronic components (I've knocked off LEDs from the non-sealed strips so be careful). These waterproof strips CANNOT be bent into nice 90 degree corners, however, so you don't really have a good option for getting perfect edge coverage with one long, continuous strip like you do with this Luminoodle product.
