ALITOVE WS2815 Individually Addressable LED Strip Dual Signal 12V 4pin RGB LED Strip Lights Outdoor 150 Pixels 16.4ft Waterproof IP67, Replacement for WS2812B WS2811 SK6812 (No Power & Controller)

Works as expected.

The LED strips are bright and colorful, but I didn't care to add another app to my phone, especially if it did not have Alexa control. Since all of my existing LED strips are controlled by the Magic Home app, which accepts on/off commands from Alexa, I did a modification as shown. I purchased a generic WS2812b controller (https://www.amazon.com/dp/B09G66L6L1?psc=1&ref=ppx_yo2ov_dt_b_product_details), removed the dual three pin interface cable and replaced it with the four pin cable that is attached to the end of the LED strips. Also, the yellow wire, BI, is connected to GND. Bottom line, excellent LED strips but for me, not so desirable controller.

Professional lighting technician here... I bought these for a simple lighting effects installation for my TV. They work just as advertised, fairly bright and good construction. It's worth noting this product doesn't come with any documentation or adhesive backing. I found the silicon waterproofing does not stick to adhesives well, but it was very easily removed. The contacts are also very easy to solder unlike other cheap LED strips. The backup data line is.a nice touch for pernanent installs. Also worth noting that these are not RGB, but rather GRB diodes. If you are installing them with professional lighting control this can mess up your colors if not corrected with programming. Overall it's a good product, but I wouldn't recommend it if you don't know exactly how these LEDs work. There was nothing in the line of required accessories or help manuals included. Just the LED strip with leads on either end.

It's pretty tough to find a WS2812 LED strip (and compatible flavors) that accepts 12v, so it's a good thing that this one hits the mark where it matters. I needed 12v to run relatively long strips (~10m at 30 LEDs/m), and I'm happy to say that to my eye, I cannot see any decrease in brightness or color accuracy at that length. This is compared to 5v strips of the same density, where they seem to be unable to reach 5m before suffering from voltage drop side effects. A few things to note: * As a reminder, there is no adhesive. The strip is 10mm wide though, and there are plenty of appropriately sized mounting tape products out there that should work * As some other reviewers have mentioned, the LEDs can heat up. This shouldn't be a problem as long as they are not bunched up together (although keep in mind that I'm using the lower density variant at 30 LEDs/m) * It will accept 3.3v for the signal input. I'm controlling my strip with a Raspberry Pi, and it appears to work with no issues. Just make sure to create a common ground to avoid flickering * There is fairly significant passive power consumption. 13.3m of these LEDs (or about 400 LEDs total) will consume about 8 to 10 watts even while "off". To avoid this problem, I've used a relay to control power input * A random few LEDs can blink momentarily when you initially feed the strip power. This will likely be unimportant to most, but I thought I'd bring it up for those that plan on using a relay to constantly turn it on and off * Quality control appears to be good. I've ordered 3 of these strips and have had experienced no defects so far (no dead LEDs, no misaligned components, the strip is completely straight and aligned through multiple segments, etc) I've been using these strips for accent lighting for about a month now, and so far have not run into any burn out issues. Overall I'm pretty satisfied with these strips. They can be fairly costly, but they get the job done. Props!

I have over 50 ALITOVE WS2811 Pixel string sets running on Xlights perfectly well for years now. So, I figured when it was time to try a few sets of LED strips that the ALITOVE brand would be the best choice. However, I'm really disappointed that the male/female connections (4pin) were Male for input and Female for output. This is the exact opposite of other LED strip manufactures and the Exact Opposite of ALITOVE Pixel strings. The Female connector is always the input from data stream. Now that could just be for some particular reason I do not know. BUT, to top it off the LED strip on the (2) units I ordered were rolled onto the reel with the INPUT (male connector) on the inside of the real and the OUTPUT (female connector) on the outside of the real. This is just begging to be connected backwards! Even the product photos, which do indicate the Male connector as input, show it being on the outside of the real. The reason its suppose to be on the outside is so that the customer doesn't need to unroll the whole strip in order to do a quick hookup test.

I strung these lights around a boat and powered them with a portable 12V battery pack and drove them with an Arduino M0 clone. They are really bright and looked great on the boat at night. A bit of water splashed on them and it didn't affect them at all. These lights are well supported by Arduino and work with the FastLED library. I initially had some trouble getting them to work reliably: these lights will sort of work with 3.3V data lines, but after I set up a little logic level transistor circuit to get the data voltage to 12V they were much more reliable. I also had an issue with ground loops: if you get these and are powering the Arduino with the same power supply, you don't want to connect both the signal and power supply grounds, just pick one.

The package came with a few clear mounting brackets and a 4 pin JST connector for data in. There's probably not enough mounting brackets for 5 meters of strip though.

I wasn't sure to buy the 150 or the 300 LED version. Finally decided on the higher density, despite the increased power requirements. Really happy with the 12 V version, it makes wiring easier. It can get warm at full brighness, I recommend uncoiling for testing to facilitate heat dissioation. The LED strip is included in a soft silicon flat tube, quite confident that is totally waterproof with the sealed ends. My project will include 4 units (1200 LEDs) along the top of a wall for a big pool party. I'm testing with a WiFi SP108E controller that could be better, however the strip is very good quality and works perfect, as expected.
