BTF-LIGHTING WS2815 (Upgraded WS2812B) 16.4ft 300 Pixels Magic Dream Color Individually Addressable RGB LED Flexible Strip Light 5050 SMD Dual Signal IP30 Non-Waterproof DC12V Black PCB

The media could not be loaded. 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 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.

The media could not be loaded. 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!

Super bright with some great color reproduction! I've got this strip stuck to the back of my TV foa ambilight. The spread is great and the adhesive is super strong

Work great, the IC leds make this an amazing led to work with. Great quality have bought a few of these and will buy more

They're bright, individually addressable, easy to use/setup. These however did NOT come with double sided tape so I was unable to set them up across a channel without adding some tape myself.

Everything about this product is great. I love BTF lighting in general, and have bought many of their LED strips over the years but none were as well made and robust as this one. They went the extra mile to encase the LEDs and the IP68 wire leads and connectors are superb.

Update: I'm updating my review after completing the project. So soldered all four strips together and protected joins with silicone and clear heat shrink tubing. Replaced remaining flat cables ends with 18awg round cables, silicone and heat shrink tubing. It required some work, but since there is nothing like it available in the market some modification was expected. The end result is fantastic! 60ft of addressable led strips around the pool with only two power inputs.I bought 4 of them. One of the strips didn't have enough silicone on the ends and water got in. The design with a 4 flat cable makes it difficult to seal, I will recommend adding some extra silicone and heat shrink tubing to make it water resistant. Two others strips developed a bad led each after only few nights of use, so let's see for how long they last.
