FAQ
Q: Can this be stripped to a red, green, and blue wire (+power) to be wired to a different board?
A:No, the WS2812 is a digital LED, it need to be controlled by a micro controller or AVR (such as an Arduino or ESP8266 board) with a digital pin and appropriate library

Q:Does this work with Raspberry Pi 3?
A:Yes, it can. As long as you have a 5v line (which the pi 3 has) then it should work

Q: Can I use raspberry pi to control the RGB led ring?
A: You can use raspberry pi to control the RGB led ring, the problem is RPI is 3.3V , and RGB led ring need 5V, so you need level shifter to convert the voltage. Please check the link: https://github.com/jgarff/rpi_ws281x

Q: Does each led require 18ma so the total 24 * 18 ma or total 432ma ?
A: Yes, total is 24*18ma, this is for normal led brightness. You can also change code to change the led brightness, and the current will be different.

Q: Is this something I can program once and not require data in? I need to program all led red or green and then power down and up to the last color.
A: Yes, you can write code to achieve this function

Q: I want to make a macro lens light. 1. is there a similar product which has a good cri white only output? 2. what wiring is necessary for that?
A: Please check this video https://www.youtube.com/watch?v=ZGHPHuuYisw

Q: What is the current draw at 5V?
A: 60 mA per LED (20mA red, 20mA green, 20mA blue) 24 X .060 = 1.44 amps.
