Maxtoch Owleyes W Pro v2 Diamond version
If you’re looking for an extreme thrower, the LEP flashlight is definitely worth considering. LEP, or Laser Excited Phosphor, uses a laser as its light source, converting a blue beam into a white-ish one with the help of phosphor, similar to an LED flashlight. Today, I’m reviewing the Maxtoch Owleyes Pro v2 Diamond version, an upgrade from the previous v2 model. While the exterior remains largely unchanged, the performance has seen a notable boost, claiming a throwing distance of 4600 meters (2.85 miles).
The Maxtoch Owleyes Pro v2 Diamond comes packaged in a sturdy hard case, although mine arrived damaged. Inside, I found the flashlight and a battery pack with three 21700 batteries. The flashlight features a single electronic switch that requires both hands to operate, and it can be used for various applications like search and rescue and wildlife spotting. While the design is utilitarian and not focused on aesthetics, the build quality is solid, with a matte black anodization. The dual-head setup with two LEP modules provides an intense beam, although the thin bezels and the performance of the red filter could use improvement. Overall, I would rate it 4.5 stars, as it stands out as one of the best throw flashlights available for under $800.
Performance
Lumen
| Mode | Specified output | Turn on | 30 sec. | 10 min. |
|---|---|---|---|---|
| Low | 250 lm | 357 lm | 347 lm | 331 |
| Med | 650 lm | 769 lm | 742 lm | 710 |
| High | 1300 lm | 1213 lm | 1138 lm | 1034 |
| High 3.76V | – | 1203 lm | 1137 lm |
It’s pretty amazing to see that even at 3.76 volts, the output is similar to when the batteries are full. So, 3 batteries in parallel definitely helps.
Runtime
Runtime tests were conducted in my 50cm homemade integrating sphere, paired with the Extech SDL400 data logging Lux Meter. Ambient temperatures are included from the moment the runtime test started.
| Mode | Specified runtime | Runtime (ANSI FL1) | Time till shut off |
|---|---|---|---|
| Low (26.1 °C) | 7h 40min | 7h 36min | 7h 36min |
| Med (28.6 °C) | 3h 30min | 3h 40min | 3h 40min |
| High (26.5 °C) | 2h 00min | 2h 05min | 2h 05min |
Throw measurements
For this test, I had to measure at larger distance because of the 2 beams. I measured this time at 50 meters distance with the Hagner E4-X Lux Meter.
However, the problem is walking 50 meters within 30 seconds, and then finding the most intense spot in the beam. My measurements are therefore on the low end of the spectrum, and in reality would be just a bit higher.
| Mode | Specified intensity | Specified beam distance | Candela measured | Meters | Yards | Miles |
|---|---|---|---|---|---|---|
| Low | – | – | 1,675,000 cd | 2588 m | 2831 yd | 1.61 |
| Med | – | – | 3,500,000 cd | 3742 m | 4092 yd | 2.32 |
| High | 5,290,000 | 4,600 | 5,325,000 cd | 4615 m | 5047 yd | 2.87 |
