It doesn't say on the website how they work? Are they like the Lumenocks? I saw some nocks atthe big box storethe other day that u put a lil glow stick inside of them. Seemed like a great idea but they only lasted I think maybe 5 or 6 hours. I also saw some lighted nocks that were magnetically activated?? Can't remember the name of them. Does anyone recall the name of them?
