Maxtoch L2KSD crazy performer
The Maxtoch L2KSD is touted as one of the farthest-reaching single-cell LEP flashlights available, but I prefer to test its capabilities myself rather than rely solely on specifications. LEP, or Laser Excited Phosphor, utilizes a blue laser as its emitter, which, with the help of phosphor, transforms the blue light into a yellowish-white beam. While LEP flashlights typically have lower lumen outputs, they excel in beam distance, with a 500-lumen LEP capable of reaching 2000 to 3000 meters, far surpassing the range of a standard LED flashlight.
The L2KSD features a forward-clicky switch for easy one-handed operation in the overhand position, though it requires two hands when held underhand. It comes with a rubber tactical ring for better grip, but using the included holster can be cumbersome due to the ring getting stuck. The flashlight package includes three colored filters; green, yellow, and red,which can be tricky to replace in the dark. The beam is narrow, making it ideal for applications like hunting and search and rescue, but not suitable for close-up work.
Overall, the L2KSD stands out with its impressive performance, boasting a beam intensity of nearly 3 million candelas and a reach of 3462 meters (2.15 miles). While there are minor drawbacks, such as the thin lubrication on the threads and the difficulty of using the filters, these do not detract significantly from its functionality. If I’m in the market for the best single-cell flashlight thrower, the L2KSD is undoubtedly a top contender.
Performance
Lumen
All of my readings were taken from a fully-charged Maxtoch 21700 battery with 5,000mAh capacity.
The measurements were taken manually at turn on and 30 seconds. The 10-minute numbers are taken from the runtime graph.
| Mode | Specified output | Turn on | 30 sec. | 10min. |
|---|---|---|---|---|
| Low | 100 lm | 194 lm | 194 lm | 189 lm |
| Med | 300 lm | 403 lm | 394 lm | 374 lm |
| High | 650 lm | 631 lm | 614 lm | 562 lm |
Runtime
| Mode | Specified runtime | Runtime (ANSI FL1) | Time till shut off |
|---|---|---|---|
| Low (26.0°C) | 4h 05min | 4h 29min | 4h 29min |
| Med (26.0°C) | 2h 10min | 2h 17min | 2h 17min |
| High (23.8°C) | 1h 10min | 1h 16min | 1h 16min |
After the runtimes, the battery measured 3V and 3.09V, depending on the mode.
Throw measurements
Measurements were taken outdoors at 20 meters with a Hagner E4-X Lux Meter, with the included battery. The measurements were taken 30 seconds after turn on.
| Mode | Specified intensity | Specified beam distance | Candela measured | Meters | Yards | Miles |
|---|---|---|---|---|---|---|
| Low | – | – | 1,016,000 cd | 2016 m | 2205 yd | 1.25mi |
| Med | – | – | 1,972,000 cd | 2809 m | 3071 yd | 1.75mi |
| High | 2,560,000 cd | 3200 m | 2,996,000 cd | 3462 m | 3786 yd | 2.15mi |
This is fantastic performance. Again, it surpassed the specified beam intensity and beam distance by a nice margin. Well done Maxtoch.
