Mateminco FW1, upgraded driver
The FW1 was measured several times to make sure the number are actually correct. Just by the sheer numbers, this is an outstanding performer.
It performed quite a bit better than most of its competitors, including the Weltool W4, or Weltool W4 Pro, and the Acebeam W30 and Acebeam W35.
However, there is a significant caveat: although Turbo mode is very impressive, there’s a thermal issue causing Turbo mode to end prematurely with the battery not yet halfway drained. Testing with a fan pointing at it worked flawlessly, confirming the thermal problem. Not knowing whether this can cause damage to either the laser module or the driver, I cannot recommend this flashlight. While it’s still usable for a few minutes at a time, it’s not recommended for something to rely on.
Performance
Lumen
The measurements were taken manually at turn on and 30 seconds. The 10-minute numbers are taken from the runtime graph. Runtimes were done with the Samsung 50G.
| Mode | Specs | at turn on | 30 sec | 10 min |
|---|---|---|---|---|
| Low (50G) | 95 lm | 118 lm | 119 lm | 116 lm |
| High (50G) | 412 lm | 532 lm | 518 lm | 498 lm |
| Turbo (50G) | 562 lm | 711 lm | 678 lm | 626 lm |
| Turbo (40T) | 562 lm | 717 lm | 682 lm | – |
| Turbo (30T) | 562 lm | 714 lm | 682 lm | – |
Runtime
Runtime tests were conducted in my 50cm homemade integrating sphere, paired with the Extech SDL400 data logging Lux Meter. Temperatures from the moment the runtime test started.
| Mode | Specified | Runtime (ANSI FL1) | Time till shut off |
|---|---|---|---|
| Low (17.9 °C) | 4h | 5h 58min | 5h 58min |
| High (18.5 °C) | 1h 40min | 1h 38min | 1h 38min |
| Turbo* ( 18.7°C) | 60 min | 18 min | 18 min |
