  • Perfect tint
  • Perfect beam
  • Great spot vs flood ratio for EDC
  • Long runtime
  • It is really small
  • Great UI
  • Nicely lubed from the factory
  • Super grip, even if it does not look like it from the pictures as there almost is no knurling
  • I guess it is not a limited edition anymore
  • Best moonlight modes
  • Full power until the battery is really low
  • I love the minimalistic package with no plastic, only cardboard


  • If you need a throwy light, pick the HI version
  • Clip could be better, if you remove it, there is a part that sticks out and it is pretty sharp.

Here is how I have my light programmed. I am not a fan of hacking the G6 and G7, to get shortcuts to behave differenly. Mine is set up, so G6 is “low/bedside night light” mode and G7 as “outside” mode.

You can change the mode with 5, 6 or 7 clicks from OFF respectively.
