Interesting Features:

Performance: Tailcap Amperage Readings

Parasitic drain: --- μmA

Performance: Runtime

Beam Profile: Tint

Flashlights are projected to a sheet of white acrylic at a distance of 15cm.

PWM (Pulse Wave Modulation):

PWM is pretty obivous in Low and Medium mode when you are using 14500 rechargeable battery.

Size Comparison:

JET-1 MK's color and finishing matched my favorite Niteye flashlights.

What I Like About JETBeam JET-1 MK:

  • Very attractive design. Typical JETBeam/ Niteye standard
  • Excellent machining and finishing.
  • Perfect EDC size.
  • Support both 14500 and AA batteries.
  • Good placement for logo, model, and serial number.
  • Threads are smooth to operate and well lube.

What Needs to Be Improved:

  • Lens fog up when light is turned on. Output level will be affected.
  • Slight tint shift to cool temperature when head turns warm on High.
  • JET-1 MK does not have a circular beam profile.
  • Although the threads are smooth, I suspect the threads are a bit loose.
  • Sample unit is slightly slanted when standing upright on tail.
  • Tapped screw hole has very limited usage. Most likely it is going to attract dust from your pocket.

Conclusion:

Coming soon

Ough! Not easy to mod? I was already imagining a 4000K light :frowning:

Thanks for the quick review

I could see that there a little gap in here. I tried to open with my bare hands but it seem to be sealed.

Haha, nothing is un-modifiable for the experts. LED swap is still possible at this stage.


Nice review and pictures! I hope the bezel opens with a bit of heat and brute force, planning to swap for a XP-G3.

Is that fogging in your light because of moisture?

Thank you. You will definitely need some help with the tools. Almost none of my lights exhibit such issue. I just left the light in my dry cabinet, will verify if it is due to moisture later.

Images are superb. You understand how to correctly light a scene. :+1: Disappointed about the flashlight’s very cool tint. Looking forward to the rest of the review.

I like dark-gray and smooth anodising typical of Jetbeam, nice that this little lights also show it; very good pictures freeme; I am again hopeful about a 4000K nice Jetbeams.

Lens still turns foggy after leaving it in my dry cabinet over night. Doubt there is much I could do, unless I open up to find out the problem.

Nice pictures!

I also have the light on order and after seeing the tint in your pictures I definitly want to change the led and if possible the mcpcb to a copper one (just to have it in there :wink: )

Can you do a runtime graph? Someting like that would be great http://i1024.photobucket.com/albums/y309/Budda_CPF/Manker%20E11/E11%20XX_zpsutk7ytpn.png

Glad you like it. I will get the runtime chart up soon!

Great!

Nice review!
I like its overall design, but IMO the head’s design is quite plain.

really great pictures!

thanks for the review

I wonder if that tapped screw hole that you mentioned can attach a jetbeam defense/window breaking cone. Thanks for the pics!

Update:

That is bad, how is pwm with a nimh?

No visible PWM with AA.

Thanks a lot for all the effort! I think that I´ll skip this one. Also it is a twisty… I don´t like AA twisties. :wink:

Still trying to unscrew the bezel …
