How long or deep is the range tunnel? Never built one but all Bass Pro Shops I have been in have a gun range for the gunsmith to bore site and zero in scopes. The tunnel as I would call it is painted flat black, and the lighting is directly above and to the side of the shooter. They use spot/flood light to illuminate the target. Only thing you can see is the target lit up light a Christmas tree. No glare or reflections.
If you’re talking about trap field lighting, LED is the way to go these days. Musco makes great sports field lighting that’s bright and even.
