Absolutely, I would never buy an LEP, I just grabbed one for a review and getting a reviewerās discount it was a great opportunity to try an LEP.
Immediately regretted it after seeing just how difficult it was to capture the beam on camera. Flashaholics channel on youtube only uses reflective buildings, but on a farm itās so much more difficult.
Since thereās zero light pollution the camera canāt use auto focus, so I need to do everything manually.
I find building footage quite deceiving for the viewer as itās an entirely different story with real world use
I find beam angles below 3Ā° to be rapidly declining in usefulness, especially for distances <1/2 their max range. Even then, often times a light with less peak intensity but wider spot provides better visibility. Iāve never tried an LEP, but I do have 1mmĀ² Osram aspheric and fresnel throwers that are quite useful for urban environments or areas with light/reflective objects in the foreground. My thinking on this LEP tech is that itās best suited to short focal length optics <40mm Ć. Cd/lm is just too high otherwise. Maybe theyād be great through binoculars?
I wouldnāt. As far as I know, Vinh mods it with a linear driver which means the light will decrease in brightness as the battery drains which makes it much worse than stock.
Laser diodes have a Vf of around 4v which a single lithium ion cannot maintain.
Good point. Iāve emailed him some questions. Iām not sure linear would matter much for how Iāll use it, but I definitely donāt want it to cycle through modes when I run the light for less than 5 seconds.
I will use it in 2s to 30s bursts, probably 30s to 120s in between. Total run time might be 5 minutes, and Iāll have backup batteries on hand.
This may not work for everyone; but you can easily sand or polish off the green tint (itās only colored on one side). I donāt hunt, and I never used the green lens. This worked well, and took maybe 3 minutes; Canāt even tell it wasnāt always clear either.
I have never used a LEP but always wondered if the amp draw was so low why most of these lights struggle to maintain turbo? Is it because the laser module is more sensitive to heat? driver output voltage?
Specially the jetbeam which hard drops to about 50% of the output
.
I will keep this one saved for future reference, just in case I get an opportunity to purchase one.
Thanks for your review: Maxtoch Xsword L2K LEP flashlight (2021 edition) reaching over 3km :+1:

I will admit the 90.2 is so power hungry, it is only good for fun, not practical use.
I have 2 lights with 90.2 leds, the one with 8 x 18650 batteries will run 2 to 3 minutes 22 amps, but the one with 4 x 18650 only 1 minute 18 amps. But they are toys for fun, not real usable flashlights. :sunglasses:

Fun fact, i bought the original 2*21700 version L2K with Chibims coupon code half a year ago or so.
After using it for a few times the length annoyed me, so I decided to contact Maxtoch and ordered the shorttube. Using it together with 2*18350 cells, it served me great.
However after reading that newer Maxtoch versions (dont know the exact model type) support single cell, just out of curiousity I just threw in a single 21700 in the shorttube and guess what?
It just works as it should!
(Did not measure Cdās yet, so i cannot guarantee the same output)
Hm, very interesting. I will have to try this myself sometime. Thank you for the info, Yokiamy! I would love to hear about your Cdās measurements with only using one 21700. I unfortunately do not have the equipment to measure Cdās.
