Update: There are now many other LED flashlights that exceed this one, see my article the Brightest LED Flashlights.
A triumph of careful thought, detailing and thorough testing, the Neofab Legion II is a new single LED flashlight that is said to produce a whopping 742 lumens. If accurate, this light will be the brightest single-LED in the world.
Reading through the details that its creator used in describing his R&D process, it’s clear that this was his baby. Much time was spent perfecting the multi-level control ring over the previous Spartanian II to make it smoother and cleaner. Teflon bearings were employed to ensure maximum smoothness. Left or right handed models allow you to control both on/off switching and leveling with your dominant thumb. A user-replaceable spring was also added. The circuit board is a a four-layer PCB and it’s paired with a 27 mm driver and .0007 ohm Vishay/Dale resistors.
The five-level flashlight offers an output of 98 lumens on its lowest setting and works up to the full 742 on #5. Using 3 18650 cells, the flashlight also offers an impressive run time of just over two hours.

Here’s some efficiency data from lab testing:
The Alcoa and stainless steel first edition was released earlier this week in a very limited 30-piece batch. The $295 may seem high, but purchase also comes with a VIP discount (90% off of future Neofab purchase). The second generation Legion II, a more machined aluminum version, will be a bit cheaper at $179. First batch is already over half gone. Legion II flashlights at CPF Marketplace.
