The media could not be loaded.  First up, I’ll talk about the LED strips themselves: As an electrical engineer I can say these are well made strips! Flex PCBs can vary in thickness and quality. These appear to be made from quality flex material with wide 1oz copper traces for power. Each individual LED on the strip has its own 0.1uF decoupling capacitor, which is important to keep communication between LEDs from glitching. (A lot of cheaper strips skip this!)The only issue I ran into was the first strip I ordered didn’t have any adhesive tape on the back of it! I contacted BTF Lighting on Amazon and they replied right away, letting me know that the adhesive should have been on the strip and that someone had goofed at the factory. They provided me an Amazon link to a roll of 10mm wide double sided tape and offered to refund me that amount (around $10) if I wanted to just order it and put it on myself, instead of going through the whole return thing. That’s pretty good customer service in my book, so kudos to BTF! (The second strip *did* have the tape installed as advertised, so I assume this was an oversight at the factor like they said.)Each strip pulls just under 5A with all LEDs set to white at maximum brightness. Cooling didn’t seem to be issue, even rolled up the strip never got so hot I couldn't hold it by hand. There were no dead pixels in either strip and brightness and color were uniform and matched between strips.Now, onto my project: Awhile back I picked up a couple of those Himalayan salt lamps at a Goodwill (I know they don’t actually emit “positive ions” or have any health benefits, I just think they look really cool). They were just begging to be customized, so I decided to replace the stock incandescent nightlight style bulbs with WiFi connected RGB LED lighting! My “lamps” both had (approximately) 3” diameter holes drilled in the bottom of them for the bulbs, so I figured it would be easy to make a cylindrical replacement.These 100 led per meter strips ended up working perfect. Originally, my plan was to wrap the LED strips *around* a 2” diameter piece of PVC piping (cut to 120mm in length). I went for the 100 LED/m instead of the more dense 144 LED/m because I thought the latter may have trouble bending enough to wrap around the small diameter of the pipe. This turned out to be a non-issue as I ended up cutting seven sections of 10 LEDs (100mm) off the roll and mounting them vertically on the pipe; this allows better alignment of the LEDs and easier management of effects in the controlling software. The 100 LED/m strips also have the advantage that the LEDs are all spaced exactly 10mm apart, which makes the math easy!First I wrapped the pipe in two layers of heat resistant Kapton tape, to prevent the pipe melting when I soldered to the LED strips. Next I adhered the seven 100mm sections of LED strip to the pipe, leaving around 10mm of free space on the bottom, I also added three small tie wraps for extra retention. Then I soldered a wire from the DO pad on the top of each section to the DI pad on the bottom of the next section; similarly I soldered very short (3mm) 20 AWG solid wire jumpers from the 5V and GND pads between sections, creating a power bus. The result is that all seven sections act as they original did before I cut them, i.e., a single strip. I also took a 1200uF capacitor and fit it snuggly in the center of the PVC pipe, then soldered the leads to the power pads of the last section. (This helps smooth out the voltage.)Finally, I took some insulating foam designed for 2” PVC piping and cut two 10mm long sections off, then slid one over the top and bottom of the pipe. These turned out to be the perfect size to act as “buffers” to hold the whole assembly centered inside the salt lamp.For the controller, I used an ESP8266 based D1-Mini mounted inside a small 2”x3”x1” enclosure. I drilled a 1/4” hole in one end of the enclosure and a 5/8” hole in the other end. A 5.5x2.5mm barrel jack was mounted in the larger hole and a small rubber grommet was mounted in the smaller hole, with the 3-pin LED connector pigtail fed through the grommet.The software running on the controller is the open source WLED (available on GitHub), which provides an easy to use web based interface for setting the color, brightness and/or effects of the connected LEDs, plus it integrates with Blynk, Alexa, WARLS, MQTT, Home Assistant and more!The attached video shows the fire flicker and rainbow effects running in my smaller lamp. The video really doesn’t do it justice, it looks even better in person. The salt makes a perfect diffuser and people honestly think there’s really a candle inside when the flame effect is going.

Great lights, really cool effects with WLED. Unfortunately I’m brand new to DIY light stuff and burned out the whole strip :(Had it all working and was excited to show it off to my partner when she got home. Unplugged it all and when she got home I plugged it in… to the… 12V power adapter that was right next to my 5V power adapter :’( they shined ever so brightly, but 1 wasn’t on and I was confused. Then another went, then 5 went out. Unplugged it and discovered my error. Plugged back in to 5V and 5 were still light up. Tried to make adjustments Imin WLED and then only 1 was on. Unplugged and replugged again and now they are all gone. RIP you beautiful 144 LED/M strip. Our time was short together, but it was beautifully blinding.TLDR; don’t be like me. Stay organized and careful when prototyping with these or you will regret it like this nooobie.Good product from BTF-Lighting

I had a defective LED in the strip of my initial order. I was able to cut it out and still have good results. However, I informed customer service of the issue and they sent me replacement LEDs as well for my trouble. They were quick to respond. The LEDs are bright and look great! The adhesion could be stronger but does the job.

UPDATE:The seller contacted me and indicated that I likely received a second hand, returned item and that was the cause for the damage. While I have been able to fix the unit I received with a little effort, the seller is going to send me a replacement. The responsiveness and customer service of the seller were excellent! As the item I received actually functions and the seller is making it right by sending me a replacement and a couple other items at no cost or obligation to me, I have updated my rating from 3 stars to 5 stars. The lights themselves really are good and work well.ORIGINAL:When I went to remove the lightstrip from the bag, I noticed that it was not fully wrapped around the spool. As I carefully pulled it out, I noticed that a portion of the strip was bent over on itself. Upon further inspection I noticed that some of the silicon covering that makes it moisture resistant had been damaged at about the third LED in the strip. Other than that it appeared intact. I plugged the string into a controller I had purchased separately and the lights lit up. I had other issues with the controller. However, when I touched the lightstrip, the lights flickered a bit and went out. I touched it again and they flickered again and came back on. I noticed that by flexing the damaged area, I could make the lights go on and off. Either there is an issue with the "wiring" in the strip or there is a bad solder joint. Either way, I can still make the strip work, but I took off a couple stars because of the damage and the fact that I'll have to do a bit of work to make them 100% functional. Not worth the time and effort to return them and play the replacement lottery when I have the know how to fix them.

Bright, never a dead pixel. Strong outdoor adhesive. Works with my WeMos ESP8266 with no additional components or logic-level shifting.

Got the 16.4 ft/300 LED version. Nice and bright, worked well with the FastLED library with an Arduino driving them. Made a great Halloween effect by simulating lightning strikes and being able to switch to different effects such as glowing/dimming red. The first reel I got failed shortly after powering it up. All the LEDs initially worked, but then a failure occurred and only the first 20 or so worked. Since the addressable LEDs work in sort of a 'serial' mode, a failure of one will affect the ones downstream of it. A replacement reel worked just fine.

I purchased the 1m 60 LED version of this strip for my PC which has a Dark Base Pro 900 case and Asus Strix X299-E Gaming motherboard. This particular motherboard has a header on the board and comes with a cable for connecting it to WS2812b addressable LED strips, which can then be controlled with the Asus Aura Sync software.After installing the LED strip and connecting it up to the motherboard it works perfectly and is also very bright. The LEDs are individually controlled so you can have, say, a rainbow or gradient effect across all of them etc.One issue I encountered when trying to install the LED strip to my case was that the sticking backing isn't very strong and starts to peel off from the inside of the case within hours of being installed. In the end, I found the best way to attach the strip was to use some sticky fixers (double sided foam pads) which are very sticky, and they have secured the LED strip nicely. Just be aware that you may want to buy some if you intend on using this strip inside your computer!The LED strip has wires and connections at both ends. At one end you have a 3 pin male plug (this fitted into the cable for my motherboard) and the other end has a 3 pin female plug, presumably to chain additional strips together. Both ends also have an extra red and white wire (with exposed ends), which is for attaching to an additional power source. I didn't need these so I cut the exposed tip off and sealed them in shrink wrap although you could use electrical tape or simply cut them off altogether.I also had to remove 3 LEDs for this strip to fit in my case properly. It was simply a case of cutting the strip with a pair of scissors where the white intersection line is marked. The really cool thing about this strip is you can cut the strip up and solder the strips together using 3 wires (+5v, GND and Data) between each strip.

Product: "Black PCB IP67"Very nice product. The following may be issues of concern for some purposes:1. Brightness levels are not adjusted for the human eye so although the brightness is fully adjustable in 256 steps, these are basically bright right down to the lowest values. Difficult to produce a nicely graduated fade-out.2. As stated this strip is made up of two half length strips joined in the middle. The consequences are not mentioned:2.1 The joint appears to be a simple solder link, more rigid and fragile than the rest of the strip.2.2 The joint is about twice as wide as the other gaps between LEDs, causing a visual discontinuity between the two halves.In fairness there is another side to issue 1: These LEDs are brighter than other neopixel-like strips I have tried. So while my displays aren't graduated so well on this, they are way brighter.On balance, full marks.

The media could not be loaded.  Have had these led's up on an aluminium track for a couple of months now. 1st of all, arrived very well packaged in their own aluminium foil packs. Once opened, was very happy to see that they have 3 pin connection blocks at both ends ( I cut these off so I can use a smaller connection block but they are handy to have to connect to my led controller ).I have used 3 packs of these led's to go right around the room they were going in and managed to stick them to the aluminium track I installed easily enough.I use wled software and the dig quad controller to control the effects of these led's and even though the software will limit the brightness due to the power limitations of such a long continuous strip, it is still very bright even in daylight. ( white is limited to around half power on a 13m long strip ). I might still go the power injection route to see if can push the brightness to full but in all honesty, it is not really needed for an inside installation.After a couple of months use, have noticed that some of the adhesive has come off the strip in certain areas and have had to glue these down. ( hence I give these 4 stars).

The media could not be loaded.  Combined these with a quinled dig uno, wled (pre loaded) a bit of frosted Perspex tube, a smaller aluminium tube and a appropriate power supply and presto one iPhone LED lamp with tons of effects. With the correct power supply you can drive these pretty bright.Started this with the intention of working with my son to show him computers, electronics, woodwork and a bit of Practical application of maths to work out the spacing of the led string on the internal aluminium tube and he ended up not wanting to do it.Did it myself and quite happy with the result so happy to keep it myself.

I've bought a couple of sets of these 100 leds/m pixel strips now, combined with BTF's SP105E Bluetooth controller and a 5v 10A power supply from another manufacturer. I've been really impressed with the quality of the led strip and BTF's customer service. While the controller software is quite basic, it does all I need and seems reliable. It picks up the Bluetooth controller and connects quickly every time, and allows control of all the basic functionality very easily. Only thing I wish it would do is save favourite modes, but you could always go old school and write them down! Also wish you could rename the controller Bluetooth name, as I may get a few more for other rooms in the future.In terms of the lights themselves, I can't really fault them. Really nice colours, very bright and super quick to change state. Also as there are so many leds/m, you get very little spotting effect if using to edge light a glass shelf (which is what I'm doing). Even better if you put them behind a diffuser in some sort of profile.Only slight gripe is there's not that many different brightness settings, but I'm not sure if that's a function of the leds or the controller - I suspect the latter again. A nice percentage slider would be welcome rather than steps. Same with the scroll speed of the modes too, not that many different speeds available, when I suspect in reality a much greater range is possible.Overall very happy with the led strips and BTF!
