Go with trl - INFORCE Gen3 APL Glock Weapon Light, 400 Lumens

I’m very disappointed in my APL. The light flickers on and off, dims and brightens on its own, it’s really just all over the place. The one place it’s never is consistently on. I contacted inforce this morning to see if they will replace or repair. I baby my guns, run them then clean and they are always in a case or holster, never dropped or abused.
