Ok, yeah I meant to say “besides the Russian thread”. This light probably deserves its own review thread. For now, here are some quick details:
Functionality: Quick press turns on in a medium mode, another quick press changes to high, another quick press turns off. Pausing at medium (longer than about 1 second) and then quick pressing turns it off. Quick double-press from anywhere, a mode level or even off turns on strobe. A quick press returns to the mode the light was in prior to strobe (a mode level or off). Press-n-hold from off does nothing. Press-n-hold from strobe does nothing. Press-n-hold from a mode level triggers a quasi-ramping of 5 output levels starting from whichever mode level you were at (medium or high) and proceeds downward to low then back to high and downward again until you let go. Low is low, not moonlight. (I’ll measure output in my sphere at some point.)
Tint: is a very crisp cool white. It actually doesn’t bother me in use. A 3C side by side with it looks yellow in comparison. The Zanflare F1 cool white even looks warmer compared to this. Sounds terribly high K, but like I said, it doesn’t bother me (and my favorite tint is a 5B1 around 4,000 to 4,200K).
Heat: I left it on in high mode for about 5 to 6 minutes and the body barely got warm. I expected more heat, so I’ll have to look into this.
USB: The light actually operates from a USB power source without a battery installed (doesn’t appear to reach highest output, but that could be due to my AC adapter or USB cord I suppose). With a cell at 4.00v it charges at 380mA. At 4.10v I’m seeing a 180mA charge rate. At 4.14v I’m seeing 120mA.
Beam Pattern: To me the light has a very good headlight beam pattern right out of the package as-is. It’s very floody with a hotspot that’s not too intense and blends nicely into the spill. Spill is quite wide. (I’m curious to try a 60º optic in it for comparison.)
The light body is a very very light aluminum. This could be a positive aspect considering it is a headlamp, but it does feel cheap due to it. General fit and finish is very good for this price level. Threads are decent and much better than many cheap lights.
I don’t want to derail this thread to be all about this light. Hopefully I can find time to post a new thread and piecemeal a review together.
*EDIT: *Battery charged up to 4.20v, charging light went green, and it seems charge current has completely stopped. Unplugging and replugging in USB triggers red charge light for just a second or two and then green.
Tailcap currents on fully charged 4.20v cell (an old, but good Protected Trustfire 2400):
Basic 2 Modes:
Medium: 0.40A
High: 1.87A
5 Step Quasi-Ramping:
Level 5: 1.87A
Level 4: 0.84A
Level 3: 0.40A
Level 2: 0.13A
Level 1: 0.05A
