I am using these to add light patterns to RC Airplanes as they fly. An Arduino NANO USB-C is used to run 5 strings of 20 LED's ea. Total current draw is 470 ma with a brightness of 95. That is about half of what they are capable of. I power them separately with an LM7805 regulator whose input is taken from main 3s battery pack of the plane or from a separate dedicated 2s 500 ma battery depending on the aircraft. The FastLED library works perfectly. Cutting the strips is easy, as is determining the direction of information flow using the arrows on the strip. The adhesive on the back of the strip sticks well to the plane but not too well. There is an infinite variation of pattern available with these. These provide a great visual tool to get young folks interested in MCU programming and electronics as well.

I love this light strip, its super bright and works great. However, if you plan on doing a large custom setup with this entire strip, make sure to wire in shunts along the strip to provide it power every 50-100 LEDs or so. Use a standard 5v power supply to do this. Otherwise you will be pushing too much current through the thin strip, which could result in damage or even a fire hazard.

Had to chop off the first third of the strip to get it working, seems like some of the LEDS were defective. Seller reached out to help.

The light strip works as advertised. Got the 16 foot version with 300 leds. Initial frustration because I used green for ground and white for data. The strip did not let out the magic smoke and works fine after I corrected my mistake. Using a Uno and the Adafruit NeoPixel library. The power needs increase quickly with so many leds. Not sure how long of a string you can power from one end using the extra power wires. Would be a good thing to add to the data sheet.The specifications for power hint that these might be RGBW leds. I have not investigated that yet.
