I've shot them at deer, twice.

1st time was on the biggest deer I've seen in my woods. I watched in horror as the "tracer" effect veered right just before I was expecting impact. I'd hit a branch. At least I knew what happened, though.

Second shot.....the lumenok allowed me to witness the best shot I've ever put on a deer. 22yds quartering away......and I aimed high on the last rib.....and hit RIGHT THERE. It was REALLY cool to see. I knew I'd put a good shot on the buck.
