I don't have a WML on any of my pistols, but if I did I'd go with the high-candela X300 Turbo.
Being able to illuminate targets at greater distances is IMO not what the high-candela light discussion should be about. A few of my own observations and comments;
- For a civilian, it's more likely to need the pistol in a low light environment, not a totally dark one. The need for bright spill in those conditions is largely lost.
- I have found the higher candela light creates greater contrast of the sights on the target, making sight alignment easier
- If I can leverage a photonic barrier to my advantage, the high-candela light makes that easier to do
- Inside a normal size residential room, there is so much reflection from the ceiling and walls that the high-candela beam still illuminates the entire space
- At 34 feet, the well-defined center beam of the Malkoff E2HT (500 lumens / 35,000 candela) measures about 24 inches in diameter. Simply centering that beam on an IDPA target makes it abundantly clear that it can be used for effective aiming at typical pistol fight distances.
Navigating a pitch-black road is easier with a broad beam. But once I become "target focused" on a threat, a more focused beam to illuminate the threat as much as possible is IMO an advantage.
