Freeme Review: JETBeam JET-1 MK 480lm XP-G2 14500/ AA - incomplete, pic only

My jet-1 MK is glued between the pill amd the body .
But i think freeme said (not sure) , it has a removable bezel.

Just received mine and I was shocked at the size of the xp-g2 (my first of this led). I was expecting an xp-g die size and quite the throw monster but have to say the beam resembles an xml2 in a larger reflectored light. Of course, it was my bad having the wrong expectations on this light, which is quite a steal for the money, truth be told.

So — moddable?
On sale: Gearbest flash sale: Jetbeam JET-I MK (AA/14500) $11, JET-U (AAA) $8

Definitely moddable. Here’s one with a Nichia 219B:

It’s just that the bezel is glued in place on the head, so you need a strap wrench or some such to get it off.

I ordered one of these lights and now need recommendations for protected 14500 cells that will work with this flashlight. I read that some cells might fit too tight.

I’ve carried one for almost two month now and i’m very pleased with it so far.

I’m not a big fan of twisties but this one is smooth enough it can be operated one handed - although sometimes it skips modes if you are not twisting off far enough and get some sort of rebounce. I’m a bit sensitive to PWM but didn’t get annoyed with it yet. Must be relatively fast PWM?

It’s small and quite bright for the size with a 14500. I like the beam shape and decent throw too.

GB has it on sale these days… Just ordered a second one. :person_facepalming:

I got 800mAh Keeppower cells

Last charge showed 848mAh

I opened it up for centering the LED and ordered a replacement XPL Hi

My advise for centering the reflector is to glue the reflector with the spacer, its almost impossible to get it centered without that, bcs it has not a typical centering ring

I ordered 3 of em only one got decent centered led

It is glued, but with some heat you can get it opened relatevily easy
Its like some soft acrylic glue

My Nitecore P12 is absolutely resistant to be opened up with more heat and way more force no chance

Lexel were the Keeppower cells you used protected or unprotected?
Thanks

Protected as the light drains em until the PCB trips
Cell voltage putting in charger is then 2.9V

Does anyone know the approx lumen level on Mid setting when using a 14500 battery? It’s gotta be more than 30.

My camera is not showing any PWM on any mode. Using a Samsung galaxy S6 camera, with a 14500 cell in the light.

get in your shower and light waterdrops you will see PWM with Lithium battery

Couldn’t tell when swinging the light, but finally could see it by pointing the light directly into the camera. Certainly don’t notice it with the naked eye. I tried it in the shower, and didn’t see anything with the naked eye. But taking a video of droplets of water, you’re always going to see a frame/strobe effect. Just like a video of an airplane propeller. I don’t see PWM as a real problem with this light using a 14500.

Falling droplets you see always with naked eye the PWM
Or taking a photo of falling droplets

Video is the most unreliable method to detect pwm

I don’t see anything like that with the I MK in the shower. Not on a photograph either.

PWM on earlier batch was not so good. Perhaps they have updated it?

I tested a 3 months old light with 900Hz PWM

1/100s image

The pwm is easily noticeable with the eyes in falling droplets as its sloeer than Convoy 4500Hz

My Jet-1 stopped working today, tried AA’s (primary alkaline, Enelop Pro) and 14500 but it lights very dimly and that’s all. So in BLF spirit i disassembled the light and everything looked fine so i decided to go further, i striped the driver and now i am trying to find driver that will fit in there so i can piggyback it on the stock contact board.

Is there some decent and widely available driver (China preferred, shipping from USA is expensive) that can be used for this light or i might be in trouble? Every driver up to 15mm should fit in there, led is going to be either the one i have now, the xp-g3 4500k or maybe 219b 5000k.

This is how the stock driver looks

and here is the contact board without any components on it, ready for another driver

In case anyone is still interested about runtime on AA cells in high mode…

Is there any imformation about the output of low and medium mode on 14500 battery?
