Review

Pros

  • Great tint
  • Great beam profi;e
  • Great spot vs flood ratio for EDC
  • Long runtime
  • Really small form factor for the 18650 powered light
  • Lightweight
  • 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

Cons

  • 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.
  • No designated hole for lanyard

My settings

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.

Lumens G5 - EDC G6 - LOW G7 - HIGH
828 PID* H1 H1
533 PID* H2
314 H2 M1
168 M2
83 M1 L1
37 L2
15.3 M2 H1
5.7 H2
