BTF-LIGHTING FCOB WS2814 IC RGBW 3000K COB LED Strip Flexible High Density Uniform Chasing Color Light 16.4FT DC24V 784LED/m 14IC/m 10mm Width for Home Indoor Decor(No Adapter or Controller)

I frequently use BTF and haven't had any problems with their products. This strip works well with no issues.

Why did you pick this product vs others?: These strips work beautifully for some cove lighting, got it hooked up on a wled controller nice and easy. Light is smooth without visible light spots on the wall, I went way brighter than i needed but it's amazing (picture has them up to about 50% maybe, generally run around 15% brightness)

These might be my next go to strips based on brightness. I wish the sections where a bit tighter for flow patterns, not as smooth as 60 led per meter. But impressively bright in comparison.

What is not stated in the description is that once you cut the strip, the remainder of the strip becomes useless. My setup required that I cut the 16.4 section down and then splice in another 12 feet cut from another 16.4 strip utilizing the BTF Lighting connectors (I could not use the tails attached to the strip otherwise I would have a section in my diffuser with no LED’s) The first 8 inches or so illuminated white when I connected the length to the first section with the power actually being off. After turning the lights on through the app, the spliced section would not turn on. After compressing the metal tabs more and more the lights eventually came on with the first strip but would not respond to color changes in the wled app that controls the lights. The lights would only illuminate with the color it originally started with in the app. I contacted the seller and they did respond to my message but did not answer the questions I asked. They just would give me specs on the lights but were no help with fixing my issue. Eventually the spliced section stopped working altogether. I spent hours setting this up in my garage and am very disappointed with this product. Now I am out a few hundred dollars and wasted hours of my life that I will never get back.

EDIT: Switching review from 3 to 5 stars due to the amazing and diligent customer support offering to rectify my experience themselves cutting out the middle man (Amazon). I am already extremely satisfied with other lights I've purchased from them (WS2815 IC LEDs) and their immediate call to action with experience has confirmed why I will continue to be a loyal customer. While this gets an A++ for brightness (see photo of LEDs as sun is beaming in the window), the segments and pixel density are extremely lacking. The obvious disappointment was getting a used product. The light reel was warped from heat, there were burn-ins on the tape, and the data direction was swapped (had to unroll and wire the side wrapped in the middle, when usually the data direction is on outside of reel). Back to the segments- as someone that uses other IC LEDs in specialized cut segments, maybe I’m spoiled (?) or maybe it’s a bit misleading to call these IC. If I was to cut a 6” strip, I’d only have access to two colors as the segments that you can control are about 3” long. Doesn’t make for great transitions and limits physical customization. Again, loved the brightness as that’s needed for my project. Probably the brightest FCOB I’ve ever used.

Used for a project for an entertainment wall, beautiful colors and easy to wire and put together.

As I have come to expect, no problems with this BTF-Lighting FCOB WS2811. In fact this is the second one I have purchased. At 24V the light is very bright and works perfectly with my WLED controller. The adhesive is of above average quality (but I always add more). The down side to 24V is that there are less individual groups but for my needs the increased brightness and only having to feed power in one end more than makes up for that.

Great quality and provides outstanding brightness. Used these in a waterproof Channel for pool coping. They have been used every night for months and work perfect!
