How many light colors can be produced using Firenock the lighted nock system?
   A total of 54 light colors can be produced from 6 LED colors inside 9 Nock colors.  Examples of actual color of light created by mixing different LED colors with different nock colors are shown below.

What light color / combination (LED color x nock color) is the best?
    In most cases, a red nock with a red LED gives the brightest light and is considered to be the best combination.
    For color blindness (red and green color blind person), experience has shown that a yellow LED with a yellow nock or a yellow LED on a green nock generally works very well.  For spring turkey hunting, a green LED on a green nock is a very good combination as game is found on a green background.
    Under indoor fluorescent lighting or for outdoor hunting on a dark moonless night, a blue LED on a blue nock looks wonderful.
