If lighting has changed then something is not right. There is not enough light for sure i just been to the range a couple of days ago. The light is spotty, uneven on a target and not bright enough. Shooting bullseye at 25m - no fun , as there is barely any light on the targets there. I hope lighting improves - it has been my only issue with the range. Well - other than the ban of the 7.62x39
