So, I’ll just add a few missing pieces and my measured data.
Thanks to Cindy from Wuben for sending me a review sample!
The D1 is targeted at hiking, camping, and general outdoor things. IP rating is ok for this (IP68, 2 m wc for 1 h), impact resistance (1.5 m) also. The ultra wide beam (spill 175 °) makes it imo more useful indoors, especially larger rooms/buildings, e.g. urban exploring.
MascaratumB did all the praise and critics already, so let’s stick to the facts:
|LED||XP-L Hi, 6500K|
|Max. lumen||1100 (ramping down to 400 within 30 s)|
|Max. const lumen||400 over 2 ½ h|
|Min. lumen||5 over 150 h|
|Max. range (ANSI FL1)||130 m (4200 cd)|
|Max. range at start||157 m (6200 cd)|
|Max. range at 400 lm||100 m (2500 cd)|
|Width of spill||175 °|
|LVP||Yes, standby when battery voltage lower 2.8 V|
|weight (f/l and f/l+battery)||64 / 117 g|
This kind of optics has been discussed on BLF already.

Wuben D1 on canvas, slightly raised to see the spill:
The first few minutes show that the initial brightness is reduced within 30 s. After that, the D1 maintains constantly 400 lm.
The specs are not met here probably since the battery was not fully charged (stopped at about 4.18 V). Still, runtime with 300 lm is impressive.
Nice exponential ramp (cd measured).
|Lumen||1100 - 400||300||100||5|
|Time||30 s + 2,5 h||5 h||30 h||150 h|
|Current||3 / 1 A||710 mA||165 mA||9 mA|
None. There’s a little ripple, but not noticeable:
Finally … the breathing:
I think that’s about it for now. I’ll add outdoor beamshots probably tomorrow.
Thanks for reading,
