Recently we have the Legion II SST-50 version. With a 4.5A output current, it's much brighter than Legion II Standard MC-E version.
What's next? I believe it's time to get a higher over-all efficiency.
====================== History ======================
I've always wanted to make a light for myself, and after I had got the idea about Legion II, I knew the time had come to make a perfect light.
Basic ideas of Legion II is from Legion I & Spartanian II. Legion I was produced by one of my friend as a LED version of Surefire M6, and a regulation resistance was added in the tailcap to control the brightness stepless. Spartanian II was a little EDC light, with a ring switch, which look like Surefire U2, but really different. The switch design of Spartanian II was beyond Surefire's patents. With a Surefire U2, you can not turn the light on and then level UP/DOWN with the same finger, but with Spartanian II you can. A real "single-finger" multi-level flashlight. The UI is even more useful for a heavy light like Legion II.
There were some bugs in my past design, for example, Spartanian II' s control ring was not smooth enough, or it rattles sometime. People could not change the spring easily too. So, I thought Legion II should be a light away from these problems.
We made it. We catched the bugs, and drove them away. The control ring, supported by new Teflon bearings, are much smoother than old ones. "Switch 'feel' is absolutely wonderful, I want to say awesome." -- By a reviewer. The spring is stronger and can be replaced by users.
We designed a brand new driver for Legion II. The base circuit board is not a double layer PCB, but a four layer PCB. Nobody ever did. The feedback loop is designed very carefully and regardless of the cost. To get the precise regulation, we choose 0.007 ohm resistors from Vishay/Dale. Nobody ever did. Finally, we got a 27mm driver, without overlapping. In the lab, we got some data about the efficiency, nobody ever did.
We decided to use 3X18650 for Legion II, the question is: should there be a battery holder? It's not difficult, but to fit a battery holder for 3X18650, the diameter of tube will be larger and larger. For example, Ultrafire just released their WF-1300L, its housing diameter is 48mm. Legion II followed another way. The tube is the holder. We also designed a brand new tailcap for it. Nobody ever did.

LEGION 2 with SMO reflector
LEGION 2 with SMO reflector
The Specs
* Powerful, Precise, Reliable Driver. ( We use 0.007 ohm resistors from Vishay/Dale. )
* Current Up to 3000mA.
* Longer Runtime Than Any Competitor In The Class.
* Best Current Regulation At Any Level, Without Audiable Noise.
* Reverse Voltage Protection
* 5 Exponential Levels.
* Thumb Control Without Strain On The Wrist.
* Revolutionary UI, The Easiest Way To Level Up/Down.
* Quick Access to Any 2 Default Levels.
* Built-in Battery Gauge.
* Over-discharge protection.
* Built-in Battery Holder.
* Ultimate Thermal Management.
* Custom Hi-End Parts.
Sample B.
Output:
2.9A(full distance)
Runtime with 3*Ultrafire unprotected 18650 cells:
2hours and 4 minutes.
With the built-in battery gauge, we can see how the cells work:
level6 (full)->level5 : About 35mins.
level5 (good)->level4: About 35mins.
level4 (fair)->level3: About 25mins.
level3 (low)->level2: About 15mins.
level2 (quite low)->Warning->level1->Auto OFF: 10mins.
When the light is OFF, you can still turn it on for emergency. At lower brightness level, the cells can still provide some energy. For example, when the light shut down at MAX level, turn it on, and switch to the lowest level (about 400mA), then use the gauge, the gauge level might be level 4 (fair).
But I recommend charging the cells when the gauge is at level 3.
Runtime from wbp
L1 = 98 lumens, L2 = 157, L3 = 264, L4 = 456, L5 = 742.
