BTF-LIGHTING WS2812B IC RGB LED Strip,UL Listed,DC5V 16.4FT 300LED IP30

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.

Looks fantastic! The difference of quality between a strip like this and a cheaper strip is noticeable. In previous strips I've owned, some lights may instantly be discolored, or the strip have issues when bent, but this strip, even under the same conditions, has performed flawlessly. I've used this same brand of strip in shorter variations for DIY stuff and it works great for those projects too.

I needed something that would work with a neopixel controller board and these worked great. You can cut them at the copper sections between the LED's. Be mindful of the directional flow of the strip. I haven't had any issues with quality or function. They also have a mild adhesive backing. They are not waterproof which also means they are less bulky without the thick outer coating other versions come with. This is important for tight tolerance applications.

I purchased these to install on my son's scooter. They're installed in low profile aluminum diffusion channel and there are absolutely no hot spots. I love that you can cut them at each pixel which made maximizing the number of LEDs easy on each side of the scooter deck. I'm powering these from a 12v->5v step down converter which itself is fed from a 60v->12v converter. No issues, stable colors, great vibrance and brightness. Setup with WLED running on an ESP8266 was as easy as custom lighting gets. Extremely happy with these and my son was over the moon with how cool they are. He gets compliments from friends and randos all the time.

Used these for an electronics project and they worked great. They look very nice and are super easy to work with.

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.

These are awesome, great quality lights. Just make sure you're matching up the power requirements needed for the length you're using and obviously the correct voltage. I'll be buying more, and in different styles. I've already used their COB lights as well as their ESP32 1200 controller. Great products from BTF

I bought the IP30 version for the least weight for my R/C airplane. But before I used it, I tested it and the LED strip stopped working. With some help from customer support, we first got a power supply from BTF that has enough current capacity to handle the LED's, and then discovered that the first LED element was defective. Thanks for your help BTF! About the LED strip, you won't want to run it at full brightness because it is blindingly bright! I found that at night, I only need to run it at 25% brightness. If you only need a few LED's then it's easy to cut the strip and re-solder on a connector. I can't wait to try the RGB addressing on my Arduino projects for some creative lighting.

J'ai reçu la bonne longueur, pas de soucis de ce côté, l'adhésif tiens bien, et les bandes sont très lumineuses. On peut les trouver moins cher mais le prix n'est pas dérangeant si on veut les recevoir vite.

...and they're at 1cm spacing. Which is what I was after. Thanks BTF.

Absolutely amazing original product. Very fast delivery and customer service was spot on! Just what I needed for my RGB project. Seller has lots of knowledge of led lights and gave solid advice! Definitely recommend!!

In Verbindung mit dem Arduino lassen sich die programmierbaren Strips leicht ansteuern. Es sind mir keine defekte oder schlechte LEDs aufgefallen.

Une super belle bande LED, facilement paramétrable, sans aucun problème, je la recommande ! Utilisée avec un arduino nano. Il est même possible de souder les bandes entre elles aux endroits où on est pas sensé couper mais attention, la zone est vraiment vraiment petite pour la soudure qui ne tient pas s'il y a un effort dessus. J'ai tout coulé sous de la colle chaude. Aucun problème au niveau des jonctions pour souder en revanche. Tips : il est possible de souder quelques fils directement sur les pattes des blocs led pour éviter les petits points en cuivre, trop petits.
