I am certain br br br Brad will be right… That 31 is just awesome. I tend to lean toward ’ floody’ lights… The BTU & TK70 both flood well. The 31 is like a freaking laser beam.
These two lights are so closely matched . I won’t even call it… Even Mrs. D says they look exactly the same at 100 yards. Here are a couple of pics. I believe the 70 looks brighter because of the CW tint.
BTU @ 60 feet.
TK70 @ 60 feet.
We just had a ice storm and Ice is covering everything. The CW of the TK70 seems to reflect much more than the NW of the BTU.
Dale, looks like you are having the same fun we just went through. I recently got my CW BTU and my brother just got his TN31 for Christmas. We finally got them out two days ago to see how they did. They are VERY evenly matched, with a tiny tiny edge possible to the TN31. Our results were 126K for the TN31 and 125K for the BTU. Both posted .3L at 600m, so they can go beyond that without issue.
Both are awesome lights. So go have some fun!
