BTF-LIGHTING WS2815 (Upgraded WS2812B) 3.2ft 144(2x72) Pixels Individually Digital Addressable RGB Dual Signal LED Flexible Strip Light 5050 SMD IP30 Non-Waterproof Magic Dream Color DC12V Black PCB

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!

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.

I have to admit I was a little bit skeptical about the functionality of these lights, but was totally blown away. These lights are really cool very bright and very customizable. You definitely get what you pay for with these lights. I am putting these lights inside my limousine. They will definitely be a great addition.

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!

I purchased these lights with a controller and transformer. I was informed by email by the manufacturer that I purchased the wrong controller for my lights. They recommended a different controller that was cheaper. I’ve purchased the correct controller and tested the lights. Turned out two lights on the string wouldn’t turn off and stayed on. I received the replacement the next day and they work perfectly. I plan on buying at least 2 more strings for floating shelves. These lights look great very bright and colorful.
