A while back, my hard anodized TorchLAB BOSS was updated from the original (as shipped) Lux-RC 371d driver, to the new firmware 371 v2.0 driver. The light itself has been reviewed already, so this review is going to focus mostly on the new firmware.
Thrunite has teamed up with The Outsider again to make a bigger version of the Thrunite TC15. It’s not just bigger though; it has some massive changes. The Thrunite TT20 The Outsider edition is available in red, uses a 21700 cell, and has a dual switch interface. It also churns out the lumens!! Read on for more thoughts and testing.
