BTF-LIGHTING WS2815 (Upgraded WS2812B) LED Strip Light,UL Listed,16.4FT 300 LED/Pixels,Flexible Chasing RGB,Dual Signal Individually Addressable,5050SMD,3M Tape,DC12V IP30(No Adapter or Controller)

So I bought these for a project an they surpassed my expectations!!! Brighter than I was thinking an made well no dead LEDs or colors! Also though in the fine print they are labeled 12v 3amp max so I get a power bank that can put that out come to find out during testing the max I can get them to pull it's 12v 1.5 somthimes 1.6 amps meaning they run even longer on the power bank than originally was hoping for so that's awesome! One thing tho they do run warmer than most LEDs I've messed around with so that's something to keep in mind!

Worked very well for my use case. Easy to cut and solder, fits perfectly inside a channel. Unlimited colors and patterns when used with SP530 controller. Used BTS connectors and 18 ga silicone wire to connect it all. Drop of only 1v at the end even after adding around 10ft of silicone wire to connect everything.

Best LED in the market. Used for Speaker beauty panels and looks bright. I highly recommend!

These lights are the ones running along the gutters and then around the base of the deck. The porch lights are govee as well as the rail matrix light. The upper run is 3 strips long of these WS2815’s and the lower is 5 strips. Both are powered through a single WLED controller on 2 different GIPO’s. The sparkle kind of effect works effectively on both the top and bottom runs. When It is turned into a red/green chase, the end of the lower run had color shifting because of inadequate power. I had to make an injector break to split the hot wire into two segments powered by 2 different power sources but keep the grounded wire and the data wire continuous.

Love theses LEDS there very bright. They can produce every color beautifully very durable I have yet to have even a single led go out and I've been buying these for years! Plus you can't beat the price and how simple they are to use.

Really happy with these RGB LEDs. They’re super bright, and the colors change fast and smoothly. I’ve got 590 LEDs (~32ft) in my setup, powered from one end and about 75% from the other, and the brightness seems to be even all the way through. Pulls around 84 watts total (~2 LED Strips) with the controller on max brightness white. These lights are in a spotless diffuser. This is the first time I have done an custom RGB setup. Overall, very solid lights!

👍🏽

These LEDs are easy to drive and seem well-made. The spacing between LEDs on this strip is very tight. I ended up using these LEDs with a Teensy 4.0 (paired with a logic level shifter) to make an RPM indicator to add a little flair to a custom sim-racing dash. The adhesive backing is just a bit too weak for bends and curves, but a tiny dab of superglue fixes that. They can get a bit warm during constant use, but I haven’t found this to be a problem. For the price, I think this is a great deal for a roll of addressable LEDs!
