i am guessing only. the driver contact disc reminds of similar lights with parallel cells. in series, 3 x 4.2V = 12.0V. The specs state 3-4.2V and i dont believe that this budget light has a fancy 4Sevens-like buck-boost-driver.
education. somehow i still think that all dogs are boys and all cats are girls :D
It should be fairly powerful on 14500 regardless of whether DD or boost/buck (unlikely since $:money_mouth_face:. The real question is how it does on AA. The most powerful AA light I have is the Trustfire 3T6 with 4 batteries in the 3x18650 config. Draws 4+A.
Sounds like it would have been better to just leave it at a 14500 light and not waste the time to have it 3AA. If it were four AA in series, I would be interested, but then it couldn't be done with 14500's too.
Seems like a boost driver is going to be inefficient or get hot?
I am liking this light, however, I am not a fan of lights that are not black. Honestly how did they come up with the name Blackshadow? Goldshadow, Coppershadow or even Bronzeshadow would be closer to a name for this.
Sorry to bug you when you’re busy but is your Rook more in the range of ~200 lumens than 1000? I just got one and while it feels really nice in the hand, for some reason mine seems dimmer than a ZL sc51, both on eneloops.
Both. After measuring the stock light, I plan to optimize it for either NiMh or Li-Ion - not sure which as yet.
While I haven't been able to measure this one yet with the I.S. (Integrating Sphere,) you are probably very close with that guess. Mine appears to be slightly brighter than a measured 175 lumen light, also on Eneloops.
The "1000 lumen" number is also closer to 600L than 1000L with 14500 Li-Ion cells installed, but an exact OTF number will need to wait for the sphere.
