BTF-LIGHTING FCOB COB LED Strip Light, WS2814 Smart IC RGBW 3000K Color Chasing Light, UL Listed DC24V 16.4FT 784LEDs/m High Density 10mm Width for Home Party DIY Decor(No Adapter or Controller)

Works as expected. Wanted the ability for the white color and it turned out amazing. Paired with the Gledopto controller and use in homeassistant couldn’t ask for more.

I built a miniature bowling lane and added these lights to each side of the lane. I bought the recommended SP630E controller kit, which connects to an app on your phone where there are a ton of cool options and effects. I’m impressed with the light output and vivid colors, as well as the length of the roll. This is serious value for money, most other compatible strips were more expensive and only 16.4ft (5m) long. I’ll be using these on customers’ builds in the future. I can also share the aluminum track with diffuser that I put the strips inside if anyone wants that.

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.

Dream chasing LEDs, best lights I ever bought will buy again

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.

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

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.

Up until now I have stuck with two different types of strips, but always from BTF. Usually, 5050's for non-addressable LEDs, or 2812/2815 for addressable ones. I saw these strips, a little different than the ones I've ordered before, so I decided to give them a try. I'm not sure if it's me, or the strips, but I noticed that their behavior is odd. Instead of the strips changing to a uniform color, the LEDs seem to be grouped together in sets of 13 LEDs per group, with 3 different color groups alternating with each other. It looks something like this: GROUP 1, GROUP 2, GROUP 3, GROUP 1, GROUP 2, GROUP 3, GROUP 1, GROUP 2, GROUP 3 Then if you send the command to change ALL LEDs to red, only the LEDs in each "Group 3" change to red, the LEDs in the Group 1 and Group 2 sections change to some other color. It's very bizarre, and this only happens to this set a 2 others I just ordered, but not to my previous sets, even re-testing them after witnessing this strange behavior. I have to assume this behavior is intended and expected since it happens to 2 other similar, but not identical, sets. Re-reading the description, I'm seeing that these strips have "addressable groups" instead of "addressable LEDs", so this must be intentional though I can't figure out for the life of me why anyone would want this behavior, and I'm sure I won't be the only one ordering these and scratching their heads afterwards. If you tell your controller to change the color to Red, it only changes one of the three groups
