I am considering purchasing this particular strip:
https://www.aliexpress.com/store/product/4m-DC5V-addressable-WS2812B-led-pixel-srip-waterproof-in-silicon-tube-74pcs-WS2812B-M-with-74pixels/701799_32325613419.html?spm=2114.12010615.0.0.1u9w0b
It is a 4 meter long strip filled up with 5V WS2812b's at 74/meter. There are 296 TOTAL pixels in this strip which is sealed up in a waterproof 'jacket'. That means that there are 3X that amount of 'led's'. 296 X 3=888 total LED's. At 20ma each at full white that is 888 X .02= 17.76 amps/string.
Because these pixels are sealed up in a waterproof jacket, that means that the total number of pixels cannot be added or subtracted to. 296 total pixels in this waterproof jacketed 'strand'.
I wonder if I even fed power at both sides, Isn't that too much current for those thin little traces in the strand? Won't that eventually burn out those thin little traces if left on at full white for a period of time? Am I forgetting something or did I do my math wrong? Anything else I'm not considering?
Thanks to my 'pixel' buddies. I'm going to post this on several sites for better coverage and possibly better answers. --Greg--
