Be careful about power... I2R losses on WS2812B 5050SMD light strips drop in voltage enough to screw the logic chip in the module after about 100-150 lights. This will manifest in odd behavior of the lights on the tail end. In particular, if you try setting and entire 300LED 5meter reel to full on white GRB=[255,255,255] you'll see soli white for about 100, then it will start to turn a warmer color as you get further down the strip, until completely off at about count 130 (these numbers are eyeballed approximations).
Actual animated color control will see odd behavior in the tail end of the light chain, depending on how bright you're setting things.
Bottom line: you need to bring power out and splice it in about every 100 or so lights.
