The JETBEAM III ST PRO R2 BVC is in my mind is a very under rated flashlight. Due to its regulation or lack of it should I say, it is perfectly suited to cycling, giving you plenty of notice that the battery is on its ways out by a gradual reduction in its output during the last 15mn of its 3 hour runtime (on high-power). Unfortunately due to the wrong instructions given by the manufacturer, it has received some mixed reviews. But once, the correct procedure has been established for setting up its three programmable modes, you will realize that the R2 BVC is a very versatile and capable flashlight. (3 fully programable modes, 225 lumens, only 120mm length and 25mm OD, 148g with 18650 battery, run time of 3h on full power, not many flashlights can boost of such features!)



Description:
The ST R2 BVC is supplied from Jetbeam in a black presentation box with a magnetic catch, inside is the light well protected by foam. Supplied with the flashlight are a small bag with 2 O rings, a paracord lanyard, a spare rubber cap for the switch, an ID/warranty card and a small instruction booklet. Flashaholics.co.uk also kindly supply 2 high quality Energizer CR123 battery so you light is "good to go" when received.
The light come in a dark putter like colour with a very good finish and split into 3 seperate parts: The head which is protected by a stainless steel bezel and host the R2 led
The reflector on my UK specs one is an OP type which I personally prefer to the smooth ones as it tend to give a brighter fuller spill without loosing much throw.
The body with knuckling and 3 flat sections, this is again is very nicely made with no sharp edges, the thread is a high quality square type
which prevent cross threading. It has the usual neat engraving on the head and body.
The flashlight also has as effective but unobtrusive anti-roll system build into the head.
The tail host the reverse clicky switch and has two holes to attach the lanyard. The tail has been manufactured so that the flashlight is able to tail stand as a candle if needed. The Tail is slightly darker than the rest of the flashlight but this is hardly noticeable.
The flashlight has 3 separates modes which are fully programmable to what ever brightness or flash mode you want; making it a very versatile light.

Output Versus Runtime
Flashlight runtime can vary quite a lot according to the quality and age of its battery, in this case a 3.7v lithium 18650 battery.
So I have carried out some some tests to give the reader a better idea of the operation life expectancy of the ST R2 BVC with the 18650 batteries.
The Jetbeam BVC was tested with two separate 2400mah 3.7v Grey Ultrafire "budget" batteries and one high quality

The light was monitored with a light meter positioned at the center of the beam one meter away, a cooling fan was switched on after15mn to keep the flashlight cool and to simulate use on a bicycle, also the heat was monitored occasionally and fluctuated between 15 to 28 degree Celsius.
The discharge curve is quite steady with the light output slowly diminishing. This is is quite useful as it does give the user plenty of warning before the battery "low voltage cut out" activate and you end up in the dark.
This is a plus for cyclist, as some of the LED lights on the market will suddenly stop working when the voltage is too low!​

So, the 3 hours runtime on high advertised by the manufacturer is achievable with an high quality 2600mah AW Battery and the output will be higher for longer.

Mode setting
thinking.gif

The ST R2 BVC has 3 modes : Mode A > Mode B > Mode C as in the instructions manual.
Now you can navigate between the 3 modes in two different ways by either half or full press of the rear clicky!
1) In off mode >full press to get into <Mode A > half press < Mode B > half press <Mode C>full press Off
or
2) In off mode >full press to get into <Mode A > full press to switch off and if switch back on within 7 seconds you will enter the next mode (B) in this case. Follow the same process to access <Mode C>

Please note, if the light is switch back on after 8 second, it will start automatically in mode A with what ever setting you have programmed in it.

Brightness setting;
Once in any of the 3 modes, you can access the IBS Infinitely variable Brightness Setting feature by a series of two steady half press, this will activate the ramping process which will start at 5% brightness increasing to 100% brightness. The light will blink twice at 50% brightness, and thrice at 100% brightness and then will start the sequence again. If you turn the light off (full press) and leave it off for more than 8 seconds, the light will memorise the desired brightness levels.
Special modes settings:
Once you are in the brightness ramping programming mode (see above) by half pressing the tail switch you will access the flash/strobe programming mode which will ramps from various speed flashes, beacon, double blink to S.O.S then will start the sequence again, to program one of the setting in your flashlight all you need to do is turn the light off (full press) and leave it off for more than 8 seconds.
Please note, the ramping time take a lot longer than the 8 seconds quoted in the instructions: mine take 20s from low to medium and 18s from medium to high. By counting the seconds between the two level of ramping you can accurately program your light to 25,50 or 75% brightness.
Factory reset:
From the Special modes/ flashing programming (see above) you also have the option of a factory mode reset, to "low, high and strobe". To do this, you will need to half press the tail switch (the light will appear off) wait a couple of seconds then switch off by fully pressing the switch again and to leave it off for more than 8 seconds.

So Next time you switch it on, you will be back to the factory settings: Mode A : low, Mode B: high, Mode C: flash.

Please note you can also enter the programming mode when the light is on by a series of six full clicks (information thanks to "Curious character", flashaholic)

I have found the Jetbeam Instruction booklet in English not correct for mine (# UK23101400026), and the Jetbeam statement of waiting for 2 seconds before switching back on, to allow for the chosen setting to be memorised by the flashlight is incorrect.
You will have to wait a minimum of 8 seconds otherwise the Jetbeam will enter the next programming mode.
So For the trigger happy flashaholics, you either will have to slow down

or get a different light

JETBEAM III ST PRO R2 BVC mini REVIEW runtime additional info

Posting the results from which l build the chart above, this may help into visualising the difference between AW and Ultrafire. I have been using succesfully the grey Ultrafire for about a year and I am still please with the way this budget battery behave, but if you can spare the cash GO for the AW, you will get more out of it.

Nice review the only problem I had with my BVC models which my 18650 only does not have is if you want to program mode B you must start in mode A and if you want to program mode C you must begin in mode B.

Other then that it's a great light with high quality I love the 18650 only model with OP reflector.

The JETBEAM III ST PRO R2 BVC is in my mind is a very under rated flashlight.
Yep, looks like a great torch and perfectly sized for my large top pocket. If it had a forward click switch I'd be all over it like a rash but the seller told me one wasn't made for it so I have to forget the nicest looking/sized JEtbeam ever made.

I could be wrong but I thought i remember some members using a tactical forward clicky. I could try swapping my Jet M clicky to my Jet III Pro ST and see if it works.

The Jet M switch is to big and made to fit differently then the Jet III. I have been searching around CPF and their is plenty of threads with the forward switch, I don't know if they are still made maybe someone else knows?

I would contact Bugoutgear I'm sure they can help you find one if not maybe someone here or at the marketplace but either way I would say you could get one if you really want the light. If none of that works I'm sure you could find one at CPF marketplace.

I thanks for your feed back, I must admit I have noticed that this has happen to me some time (not always) and I put it down (for me) to may be doing a series of 4 quick half press instead of 3 (not knowingly) therefore jumping to the next mode before the programmable mode kicked in, so you would end up reprogramming in fact the next mode.
Like many of you when this happens, I find this is very frustrating.


Now would we have been misguided again by the instruction book,
thinking.gif
stating a

"lightly press onto the tail cap three times or more continuously within a second"
from my review and revised instructions
"you can access the variable brightness setting by a series of 3 rapid half press"
well this does work for me but I do get sometime the reprogramming of the next mode instead of the one I am into.


So I went back to the drawing board again:confused:, and did more testing.
Now all owners of ST PRO R2 BVC, I would be grateful if you could try another way of entering the programmable modes.

At first reset light to manufacturer setting so you know were you are high/low/double flash

Now, this time in which ever mode you want to be in and reprogram A, B or C

DO A HALF CLICK/PRESS FOLLOW EMEDIATTELY BY A SECOND HALF CLICK/PRESS, DO NOT RUSH AT ALL BUT DO NOT LEAVE A GAP,
NOW AFTER A FEW SECONDS MY LIGHT START RAMPING, (I BELIEVE YOURS WILL)

1) YOU CAN SET THE RAMPING MODE BY A FULL CLICK, AND LEAVING IT OFF FOR A MINIMUM OF 8 SECONDS.

2) OR YOU CAN ENTER THE RAMPING FLASHING MODE BY ANOTHER HALF CLICK/PRESS. TO SET IT, AGAIN A FULL CLICK, AND LEAVE IT OFF FOR A MINIMUM OF 8 SECONDS.

3) OR TO REPROGRAM THE LIGHT TO MANUFACTURER SETTINGS DO ANOTHER HALF CLICK/PRESS, FOLLOWED BY A GAP OF A COUPLE OF SECONDS THEN SWITCHING THE LIGHT FULLY OFF BY A FULL CLICK.PRESS AND LEAVING IT OFF FOR 8 SECONDS OR MORE.

Now I have tried this over and over in any of the mode A, B, C, and I managed to program the mode I was in every time without fault.
Again i would like your feed back, so in short you need to half click two enter the program modes (FORGET ABOUTH THE 3 HALF CLICKS WITHIN A SECOND)

let us know, this is a good looking and versatile light and it would be great if we could have it working well for everyone!

Regards

You are not wrong jhc. A forward clicky used to come with this light as well as the reverse clicky. Now it is only available with the reverse. I bought mine from lightjunction.com, and the guys there got in touch with JETBeam and got me the forward clicky assembly. I actually love this light with the forward clicky. The assembly consists of the four pieces in the picture below. You have to have all four of these pieces.

Rubber boot, plastic spacer, forward clicky, metal screw in retaining ring

I noticed BOG sells a forward switch for the Jet ll so how about that one does anyone know if that switch will fit and come with the correct parts?

Nice review -- thanks. But you need to relabel your graph -- that's lux, not lumens. Mine measured about 5000 candelas (5000 lux at one meter) and about 209 lumens with an 18650.

It's awfully ringy with the smooth reflector. Write-rite helps but the rings are still obvious.

Sorry Guys ,

this is supposed to be LUX not lumens on the graph,
will change this later on, how did I not spot it ??:sick2::sick2::sick2:


Question for you , how do we convert Lux to Lumens, did a fair bit of reading on the net, but I have been unable to find a reliable way of doing so, this why my lumens are all estimated

They must like you. They were the ones that told me there wasn't a forward switch available for it. I may have to approach them again now that I'm armed with a little more info.

Well, to be honest Dave, it was not that easy for them to get it for me. They had to request from JETBeam several times before they finally sent the right parts, and I kept bugging them to bug JETBeam. All I can say is that they are really great guys, but probably have enough hassle with their regular business....let alone trying to get a pushy customer(speaking of myself:grin2:) a part that JETBeam doesn't provide with their lights anymore.

I have another set I would be willing to send to you if you would be willing to pay for the postage. PM me and let me know.

Very kind of you bondr0006 I'm sure he will be glad to hear it now maybe he can get the light he wants. It seemed he really wanted one and it's a great light that's why I was trying to help him find one best I could.

Best Skyraider59
Lux and lumens are measures of different things, so there's no direct way to convert from one to the other. Lumens is the total light output in all directions, while lux is the intensity in one particular direction. So a flashlight has one total lumen number, but the lux value is different in each direction. For a given number of lumens, you can get higher and higher lux in a smaller and smaller beam by tighter focusing. A high lumen light won't light anything very brightly if there's no reflector, but even a low lumen light can light up a small area very brightly if well focused.

Inexpensive meters are readily available to directly measure lux. But adding up the total light in all directions is a much tougher job. Ceiling bounce is a way to get a rough idea of the total light output. For lumen measurements I use a very crude and simple light box described by Quickbeam, made from an aluminum foil coated milk carton. I've calibrated it by measuring a number of bare LEDs, assuming that the published values for output are accurate, and a few flashlights with fairly reliable output. I can't make any claim for accuracy, but the values I measure are consistently in line with the emitter specs, so it's in the ballpark at least.
