I use Firenocs in all my arrows for hunting Tried all the other brands and found Firenocs to be head and shoulders above the rest, longer battery life, more durable, a lot brighter, ability to replace the battery, specifically made for whatever arrow you use does not affect the flight or accuracy
My eyes aren't the best and the Firenocs let me see my shot, watch the arrow go through the critter and allow me to find my arrow.
