JetBeam II PRO [Review]. Updated: runtime, beam

User interface JETBEAM II PRO:

1. Direct access to moonlight mode from off: 2 fast clicks
2. For turn on or turn off, simple click. Memory for last used: Low , Mid or High. (memory not include moonlight mode)
3. Change modes, when flashlight is on keep depressed the swith: order of modes; High, Mid, Low, High, Mid……
4. Strobe: 3 fast clicks. Available with flashlight “on and off”
5. Electronic Lockout: When flashlight is turned off, long press for more than 3 seconds (flashing and lock). To unlock long press for more than 3 seconds. But the moonlight mode (2 fast clics) and strobe (3 fast clics) are availables with the lock actived.
6. Timing function: With flashlight on, 4 fast clics for activate 3 minute countdown for off, 4 fast clics again for 9 minutes of count down for off.

Coments: when we access to the moonlight mode, if you keep depressed the switch, alternate high-moonligh-high-moonlight….

for the control this nice electronic switch:

Hey!!, this Holster fits perfect 100 % for the JetBeam II PRO (when using the smooth bezel), but only left 5 units in stock:

(I have used for long time with the Olight S1)

Holster banggood

The ultralow is a really Moonlight mode;

I will work this night in a some information about regulation for high mode.

A first data about regulation.
Temperature in Celsius is around 27ºC, (ufff), I have make a little test of 6 minutes, without fan (hard test). Battery is a Klarus 16340 640 mA in good condition. I have meassured data each 15 seconds. Temperature over head surface 1 data for minute. Step down begins around after 3 minutes, lumens down 520——–270 (in aprox. 20 seconds):

now running the complete runtime…

keep on the great work

I have finished my first complete runtime of the JETBeam II PRO. I have used a 16340 Klarus protected battery in good condition.
First 16 minutes without fan, (here temperatures are high now) after 16 minutes I have used a fan.
I have used for this complete runtime one data for minute.
Step down after around 3 minutes (light down to around 55% or original power).
After shut off (abruptly, perhaps protection of battery …. I have measured Voltage after some minutes and read 3.05V)

3 minutes of 500 lumens and around one hour 250 lumens …is a good result for this little light!

Thanks Trevi lux,

I just placed an order for one of these and i am very much looking forward to its arrival.
This seems to tick all the boxes with the ui,regulation and interesting bezel.
I cant help but notice the user interface\timer is almost identical to the excellent olight s1 .

Any comment on the throw and beam shape of this light with the xpl hi. [4800 cd ?]

Hi;
Sorry for delay, today again in my house, I will coment about beam.

Reminds me of 47’s Knight and Paladin.

It needs more spikes :person_facepalming:

Already have mine on order should come any day now, can’t wait because I really like the way it looks and is shaped, minus the “attack” bezel part (oddly enough). Thanks for the great review, by the way hows the tint on this thing in your opinion?

Hi guys, some about tint and beam;
I have meassured in the center of the hotspot at one meter: 5400 lux (5400cd) , with a 16340 battery with 4.2V

Led seems slightly out center, but the beam is perfect:

Of course when use the strike bezel in attack position, there are one artefact:

The beam is cool tint, nothing special, here with a warm tint of the Spark SF3 NW (they say is neutral …) and the very cold tint of the SW V11R XM-L2:

Here animated Gif:

Images pole + and - :

Thanks Trevi lux, looks like a neat clean beam, hotspot from the xpl hi and handy throw for its size. The head looks easy to remove if any one wanted to swap the led.

I like the RCR123, 16340 capable lights for there small size, good output ratio and low weight.

Personally i like the stainless steel attack bezel and appreciate the machining that has gone into this little light- its certainly not a boring round tube like some other brands trot out.

Really looking forward to mine turning up and thanks again for your review and detailed information.

My 11 pro turned up today and i am very impressed and would like to add a couple of extra points,

Immediately what stood out was the silky smooth and light pressure metal ui switch.
The build of this light is very nice, with a lot of fine detail machining this tiny light stands out and makes an impression.

I thought the medium runtime seemed a little low at 1.5 hrs as stated in the manual, so i tested it with my AW RCR123 imr unprotected 550mah cell and got almost perfect flat regulation for over 2.5 hrs.

Start lumens [med level] 123

2 hrs 30 mins 118 lumens

At 2 hrs 39 mins the light started decrease in output and went into a slow flash / low voltage warning . [cell rebound voltage 3.03v]

Samples vary, i measure the throw at at 6100 cd compared with my olight S1 at 3000 cd with a nice wide spill and defined spot.

This little Jetbeam reminds me of some of their excellent earlier model quality lights.

Is the clip removable ?

Thanks,
Mike

very nice review, thank you! :slight_smile:

Anyone managed to get the bezel off the titanium version?

I’ve tried, but it appears to be heavily glued. I think a blowtorch might be needed.

Anyone had any luck emitter swapping these?

I like it, but I'm not a fan of the strike bezel. It is nice to have the option of a normal bezel.

I got one last week. It’s by far my favorite 16340 pocket rocket. Also the best looking!

Currently drooling the Ti version of this light. :smiley:
