Got a excalabur lunizone few years ago 10 yards up to 50 dead on and theres a switch where you can have the reticles iluminated for low light conditions,I dont think I ever had to use the light feature yet but nice to have and it is the best xbow scope I have ever owned..Its dead on..The new ones have choice of red or green illumination,But they are different name now so I cant speak how good they are but im sure they are just as good and have a great service dept.and lifetime warranty.
