500pcs WS2811 LED pixels lights

Dec 12th edit:I have to eat a big dish of Crow, my first review was completely wrong. Rather than using a complete LED controller like DigiQuad, I was using a basic ESP32 with WLED to test the pixel strips. Originally the ALTILOVE brand wasn't working well at all, while the Rextin brand was functioning. I had planned to ship the ALTILOVE back and even had Amazon send me a return label. Then I began having problems testing the Rextin brand that was already hung on my house. After investigating it, I read from DrZzzzz that the ESB32 Data Output pins provide the absolute bare minimum signal voltage for the WS2811 chip. Even a short wire run can degrade the signal enough to cause problems. The ALTILOVE must have been more sensitive than the Rextin. I installed an F-Amp inline voltage translator right at the output of the ESP32 and that solved every problem I had. All ten 15ft strands of these lights work perfectly now. I was even able to chain eight in a row and they worked flawlessly, another inline F-Amp and the last two made it ten complete strings all running of the single output. Please disregard everything I said in my initial review. These pixels work great, putting them on the house this weekend.******************Completely incorrect initial review below.***************************************I purchased a set of these LED lights on Nov 22nd, brand was Rextin, $143. They have worked flawlessly. Color is great and they respond to WLED perfectly. the first two pictures ore of the Rextin brand. Amazon pushed me an AD for a set on Nov 27th at $115, I am guessing as part of Cyber Monday. Although they look similar, they are not, these are ALTILOVE and they are trash, buyer beware. 80% of the strands have failed, six won't turn on a single LED, two have a few that light, and two light completely. The tird picture shows a strand where only LED 1 lights.They are very obviously from different manufacturers, the wire color is different. But these ALTILOVE are garbage, waste of money and effort, if you bought them, test them as soon as they come in so you can return the defective ones. Only blessing was I tested before I hung them, so I didn't have to do a bunch of rework.Steer clear of the ALTILOVE brand.

Works well

De helft is al kapot

Perfect

Constantly having individual pixels fail. Had at least 10 fail over the last few months. My pixels are installed under cover, out of direct sun and rain.
