I might be compact (and some may dare call me cute) but to you, it's still Mr. Elfin SIR!!

As part of my new standards for my reviews, I measure the performance on my PVC LMD by first calibrating the sensor's positon w/a Xeno G10v2 (immediately perfectly regulated in med. mode):

Mr. Elfin is rather particular about his outputs depending on the battery being used. Case in point, Turbo (replaces H) can only be achieved via 4.2v LiIon (regardless ICR or IMR). Even LiFePO4 and primary cells create different outputs. Below are what I've measured for 3 different battery types.
Turbo - 288lms (~1600lux @ 1m) | Med - 82lms | Low - .3lms
Turbo was taken @ roughly 37 seconds but was 288 @ 31 seconds
Turbo - 137.8lms | Med - 29.2lms | Low - .3lms
Turbo - 215lms | Med - 55.4lms | Low - .3lms
The LiFePO4 output is rather curious since I had expected it to be higher than for the primary given the nominal v. I'll recheck its measurement and add a RCR3.0V as well.

I've been receiving a bunch of requests to produce white wall beamshots so I decided to use selfbuilt's exposure settings (clockwise: 1/25, 1/100, 1/800, 1/1600 @ f2.9 on AWB) to allow for some consistency (and thus reference) in these shots (however, in my shots, the light is ~.4m to wall / camera ~.59m) . Of course they will never perfectly match up due to differences between our cameras.
The first set is on AW IMR's and second on LiFePO4's to allow you to compare the difference between Turbo vs. High modes.

The relevant battery stats are provided above each runtime graph along with:- Voltage of the battery at the start and end of the test
- Current draw as taken right before the test
- Actual runtime using ANSI FL1 (first in HR and then in M so for the TNGY read this as 1.3 Hrs OR 86 Min)
- Also captured the temperature: ambient, the head at start and the max it reached (fan was used w/all bats)
Turbo can only be achieved through the use of LiIon RCR's. Case in point, the yellow run is for a LiFePO4 and would not enter Turbo mode. Sunwayman doesn't provide the runtime on RCR's since they warn against running in Turbo for longer than 10 minutes, however, as you can see above the temp doesn't really get too bad (keep in mind though this is w/a fan on). As for the runtime on High, they quote 1.5 hrs on primaries and given that I was able to achieve 1.4hrs using LiFePO4's which have very little capacity, I expect that runtime to be met if not exceeded.
Also, looks like this can be a battery vampire provided the light remains on during the entire run. Case in point, the AW IMR and LiFePO4 were both overdischarged. I can't recall if the PCB kicked-in w/the AW ICR but if using RCR's, it'll be best to stick w/protected cells.
I had a used primary w/resting voltage of 2.89 and was able to power all modes. Another w/resting v of 2.57 wouldn't even turn on in low mode. I was hoping that this would indeed be a true battery vampire (ha, Mr. Elfin... the battery vampire) since I have a few primaries I'd love to drain completely.

Mr. Elfin's head/body is completely interchangeable with his V brethrens.
