I tried Luminoks years ago did not like them. they came on after i shot yes but one day a light rain came thru and after sunset i noticed all my Luminocks were glowing from the rain creating a full circut. I don't know if they were too tight in the arrow shaft or what but never used them agian. This season i bought Nocturnal in green color worked pretty good only one out the 3 in the pack was not a good fit in my arrow shaft. Alittle diff to turn off untill you learn how. I have not used them yet but plan to.
