Thread: JetBeam RRT-2 Raptor (R2) Review: RUNTIMES, BEAMSHOTS, and more!

  1. #1

    Rolleye11 JetBeam RRT-2 Raptor (R2) Review: RUNTIMES, BEAMSHOTS, and more!

    Reviewer's Note: The RRT-2 Raptor was provided for review by JetBeam. Please see their website for more info.

    UPDATE SEPT 27, 2011: JetBeam has released a new series of RRT lights, with a continuously-variable interface. Please seen my recent RRT-21 and RRT-15 review for more info.

    UPDATE SEPT 22, 2010: As this review is over a year old, it is not surprising that the RRT-2 has gone through a number of build modifications. Please see post #98 by Ecodelosandes for some detailed pics of the currently shipping XP-G R5 edition of the RRT-2.

    Warning: Pic heavy!



    Manufacturer's specifications, as taken from JetBeam's website:
    • Rapid Response Activation Ring allows the user to select between the three various brightness levels and strobe function. Stainless steel ring, increased reliability and durability.
    • Features new randomizing strobe

    The RRT-2 is the "second generation" of the JetBeam Raptor line. The original RRT-1 Raptor was designed to be a fairly strong "thrower" with a simple control-ring user interface. The revised version has a much smaller head, but still provides significant throw for its size, thanks to a deep reflector.



    The RRT-2 comes in fairly standard JetBeam packaging for this size of light - a hard cardboard box with magnetic closing flap. The light comes with a manual, warranty card, spare o-rings, and spare tail-cap switch. Note there is no wrist strap or carrying pouch included on my sample.

    One note to make up front – the user manual is rather inadequate for the light. Although it does cover the basics (i.e. how to turn on, insert a battery, and change light modes), it provides no detailed specs or background on the light. If you don't already know what batteries are supported, what components are built-in, etc., you are out of luck. But it does emphasize the the fact that the "Standby" mode is not a true off, and should only be used as temporary off (see my UI discussion below).





    From left to right: 1xAW protected 18650, JetBeam RRT-2 Raptor, NiteCore SR3 + 18650 body tube, JetBeam Jet-III M, Olight M20, Tiablo A10-G, 4Sevens Quark 123.

    Dimensions: Weight 172.4g, Length 150mm x Width 35mm (bezel)

    The light is a bit larger than the typical 2xCR123A/18650 light, likely due to the control ring mechanism and deeper than typical reflector (for greater throw). I don't find it unreasonably longer.

    Note the slightly scalloped bezel ring (stainless steel) and control switch ring (aluminium?) and the protruding forward clicky.




    The clicky feel is very similar other modern JetBeam lights with a forward clicky. In fact, the entire tailcap assembly appears to be identical to my JetBeam M1X – they are interchangeable among the two lights.

    Fit and finish are excellent on my sample, no flaws in the type-III hard anodizing (which is in JetBeam's typical dark-grey natural finish). There can often be significant mismatch in the color of natural anodizing between different components of a light, but my sample seems unusually consistent.

    Identification labels are very sharp and clear, similar to the M1X (and an improvement over earlier JetBeam models). Labels are not as bright white as some other makers, but that actually helps to make them less obtrusive. Knurling is fairly standard for JetBeam (i.e. not very aggressive), but the presence of additional design elements with raised/flat portions helps with good hand grip.

    Like other JetBeam models, screw threads are anodized for head or tailcap lock-out. The light cannot tailstand, due to the forward clicky.

    Note the significant brass heatsink in the head region of the light.



    Despite how the photo above looks, the reflector is actually smooth. There appears to be an ever so-slight rippling pattern to it, which combined with the reflections of the scalloped bezel ring, give the misleading impression in the photo above.

    The light uses the standard Cree XR-E emitter, with a R2 output bin in this case. As you will see in my beamshots below, my sample seems to be a premium white "cool tint" (I'd guestimate WC tint bin). Obviously, there will be some variability here – there is no guarantee as to what you could receive. Most R2s that I've seen have been on the warm green/yellow end of the "cool white" spectrum – likely WG/WH. For those of you not familiar with tint bins, please see my Colour tint comparison and the summary LED tint charts found here.

    Observant viewers will note the apparent speck of debris or manufacturing defect on the smooth reflector (roughly 4 o'clock position). Please note that this is actually very misleading in the photo - it is a reflection of a much smaller defect, located closer to the emitter (i.e. it is being magnified by the angle, just as the yellow phosphor die of the emitter is being picked up and magnified by the reflector). . Nothing you can do about it, and it doesn't seem to affect the beam.

    UPDATE: I forgot to mention it originally, but the beam is somewhat focusable - you can twist the head region separately from the section with the output mode labels. In practice, all this does is let you defocus the beam slightly, as the range is limited. Helpful to allow you to achieve the best possible focus, but not much else. Mine came default at what I determined to be the best focus anyway.

    Comparison Beamshots

    Note that I inadvertently set the camera to an f-stop of 2.7 for the RRT-2 pics (instead of 3.2 for all my other reviews). So that will make everything seem a bit brighter on that RRT-2 row.

    All lights are on 100% on an AW protected 18650, about 0.5 meters from a white wall.










    As you can see, the RRT-2 has a typical "thrower" appearance with a well-defined hotspot and some rings in the beam. On the whole, I don't find it too extreme in either aspect.

    UPDATE: Some additional long-distance beamshots, to show you how the light compares to others in its class.

    Please see my recent 100-yard Outdoor Beamshot review for more details (and additional lights).






    User Interface

    The Raptor uses a new interface for JetBeam, previously well known for their continuously-variable IBS designs. This new interface is much simpler and very intuitive to use.

    Light is turned on/off by the tailcap forward clicky (press for momentary, click to lock-on). Screw threads are anodized, so you could also use it like a twisty switch.

    Output modes are controlled by a ring below the head. There are 3 constant output modes and an oscillating strobe mode, as well as a "standy mode" that is basically a temporary off. The closest comparables to this ring are the EagleTac M2-series lights and the new NiteCore SR3, although each model has its own particular aspects and features.

    To access any of the 5 settings, simply turn the control ring. There is a dot indentation on the ring to tell you which mode you are currently in, by lining up with the marks on the head (something my EagleTac and NiteCore lights don't currently have, but may be in development). From left-to-right (i.e. clockwise if holding the light away from you in standard underhand carry), the dial turns from Hi – Mid – Lo – Strobe – Standby. There are pronounced detents at each level, so you feel the ring "click" into each output level as you reach it. The total traverse of the ring is less than half the total circumference of the light.

    UPDATE: An unusual quirk - each mode has a brief low intensity flash and short delay before lighting up when you press the tailcap. CPFer HKJ reports the flash to be 20 micro-seconds long, followed by 120 milliseconds before full activation. On Standby mode, you will only see the 20 us flash.

    "Standby"

    The "standby" mode is like the "off" position of the ring on the EagleTac M2 lights – when in this position, no light is produced. However, on both lights, current is still being drawn to allow the circuit to respond to a change in the state of the ring. Unless the switch is clicked off or the current path is broken by locking out some part of the light, this "standby" mode will continue to draw power. As such, the name "standby" is more appropriate than off.

    UPDATE: CPFer HKJ reports that the standby current is 2mA, which is fairly high for this sort of mode - it will completely drain your batteries within a month or two if left on like that (hence the warning in the manual).

    What I don't quite get is why it is located after the strobe mode instead of after the lowest output mode.

    "Randomizing Strobe"

    JetBeam describes the Strobe mode on the RRT-2 as a "randomizing strobe." That is not quite correct – it is in fact an oscillating strobe that switches between four distinct strobe frequencies very quickly. Each strobe frequency last ~0.5 secs, and they loop in continuous repeat, starting with the highest frequency. Here's what a 4 sec trace looks like:



    The light comes on in a very fast (and very annoying) 21.8 Hz strobe, followed by a just slightly less annoying 15.2 Hz, and then a 6.6 Hz and 5.5 Hz strobe. As I mentioned, each frequency lasts for about 0.5 secs, and then the whole thing repeats.

    I am not really sure of the point of this. Perhaps the reasoning is that by rapidly oscillating between four difference frequencies, the strobe is more disorienting? Personally, I doubt you could easily steel yourself against a constant strobe in the 15-20Hz range. I will leave it to your judgment as to how "tactical" this innovation is. Is it "random"? No. Is it really, really annoying? You bet.

    No PWM (Pulse-Width-Modulation)

    I was unable to detect any signs of PWM, and so must conclude that the RRT-2 doesn't use PWM to create its lower output modes. That would be consistent with the relatively bright Lo mode on the light (i.e. you typically need PWM to get down to really low outputs). I understand from Tohuwabohu's posts here CPF that the light is PFM (i.e. pulse-frequency-modulated) rather than classic current-controlled, but I don't have any other specifics.

    Testing Method: All my output numbers are relative for my home-made light box setup, a la Quickbeam's flashlightreviews.com method. You can directly compare all my relative output values from different reviews - i.e. an output value of "10" in one graph is the same as "10" in another. All runtimes are done under a cooling fan, except for the extended run Lo/Min modes (i.e. >12 hours) which are done without cooling.

    Throw values are the square-root of lux measurements taken at 1 meter from the lens, using a light meter.

    Throw/Output Summary Chart:







    As you can see, the RRT-2 is more of a thrower than other multi-purpose lights in this size (e.g. JetBeam Jet-III M, Olight M20, NiteCore SR3 + 18650 tube) – but not hugely so. Obviously, throw can't compare to the dedicated modern throwers with bigger reflectors, like the Tiablo A10-G.

    Overall max output on the RRT-2 is certainly very respectable for a multi-power R2-based light (i.e. about the same as the Quark 123-2 and Olight M20, on all batteries). But of course, the dedicated 1xLi-ion lights can potentially exceed it.

    Min output is brighter than most of the other defined-output lights.

    Output/Runtime Comparison:












    Runtime performance is generally quite good across the board. When matched for output, the RRT-2 can generally out-compete the continuously-variable competition (especially the older IBS-based lights). But relative to the defined-output group lights (many of which are current-controlled), it is really about an average performer.

    Runtime pattern on 1x18650 and 2xCR123A is a little unusual once the light drops out of regulation. Normally on 18650, you get either an abrupt shut-down when the battery protection circuit is tripped, or a long decreasing output and “moon mode” phase. In the case of the RRT-2, the light appears to drop to a new regulated Med level for a short period of time before cutting out.

    On 2xCR123A, the light appears to repeatedly attempt to return to a higher output, leading to rapidly switching output levels and quicker exhaustion of the batteries. This is different from the low-voltage warning signal on the early ITP C6 and Olight M20 lights shown in the traces above (a feature I believe has since been removed from both lights).

    Potential Issues

    Being a new interface, the switching control ring may not suit all users. But I personally find it has the best feel among the three recent lights I’ve tested with a similar feature (i.e. compared to the EagleTac M2XC4 and NiteCore SR3).

    Low mode is not as low as most other defined-output or continuously-variable lights.

    Mode sequence is a bit odd, placing the strobe mode after the Lo mode (instead of after the Hi mode), and placing the standby mode after strobe (i.e. have to enter strobe before accessing standby?).

    Runtime pattern is a little unusual on CR123A, once the light drops out of regulation.

    No anti-roll features.

    General Observations

    The RRT-2 Raptor is JetBeam’s offering in the new "one-ring-to-rule-them-all" world of flashlight design. I find it interesting to see how each maker has implemented the idea of a rotating control ring. JetBeam’s ring design has the best "hand feel" to me (i.e. best combination of resistance and detents). It is also the easiest to figure out where you are (i.e. good surface markings). Like Goldilocks, I find the physical implementation of RRT-2 control ring to be just about right.

    What I don’t quite get is the sequence. Why would you want to access strobe right after the lowest mode? And why would you put strobe between the standby mode and the constant output modes? A more sensible sequence in my mind would be Standby / Lo / Mid / Hi / Strobe (or the reverse order, if you prefer) - much like the EagleTac M2-series lights. UPDATE: thanks to a suggestion from CPFer gilly, I've discovered you can easily skip over the strobe mode by twisting the ring quickly. There is a ~120ms delay in the activation of each mode, so that seems to give you enough time to make it without seeing a strobe.

    I am also not really clear on the advantage of this oscillating strobe sequence. I suspect constant strobe in the 10-20Hz range would be annoying enough for "tactical" use, but I'll leave that one to the experts to discuss. Given the trend toward ever-increasing stobes, can I make a plea for someone to bring back the slow frequency blinking-style beacon strobe? I realize that this may not be the light for it, but I think "tactical" strobe is getting a bit over-done.

    The lack of a true low mode may be disappointing to some, but I don’t personally find it to be too big a drawback here. Although nice to have, I never really understood the exclusive bundling of really low modes on "thrower" lights (e.g. RaidFire Spear ). To me, it makes more sense to have a couple of battery-saving medium modes to extend runtime while keeping decent throw. But if a low mode is important to you on a light like this, you will need to look elsewhere.

    I like the fact that the RRT-2 takes all possible battery configurations (i.e. 2xCR123A, 2xRCR, 1x18650). And with consistent output levels and regulated runtime patterns on each battery source. Dedicated 18650-only lights may be capable of a bit more output, but you loose the flexibility to use primaries in a pinch.

    Bottom line, the RRT-2 has a lot of nice touches. It also has excellent build quality - JetBeam has really managed to impress me with how solid their lights feel lately. But as always, what matters is whether or not it has the right combination of features and performance for you.

    P.S.: I have justed tested them, and the Olight diffuser and filter kits for the Olight M20 are a perfect fit on the RRT-2.

    P.P.S: Unlike many of the recent competition, the RRT-2 seems to be able to handle flat-top 18650 cells. This is becoming an issue as more users begin to switch to the higher capacity protected 2600mAh cells (which lack the standard button top).


    UPDATE SEPT 27, 2011: JetBeam has released a new series of RRT lights, with a continuously-variable interface. Please seen my recent RRT-21 and RRT-15 review for more info.

    Very thorough, as always!

    JetBeam build quality always seems good, which is reassuring, however maybe the UI, standby mode and strobe need some re-thinking here. In standby mode it would be too easy to think the light had been properly turned off, and the multi-frequency strobe sounds a bit of a dog's breakfast to me...

    Moving to the Reviews section.
    Resistance is futile...

    Thanks David.

    Your comment about Standby just prompted me to add a point to the review - to their credit, JetBeam does give a strong warning in the manual that the Standby mode should only be used as a temporary off, since it continues to draw current. Although I find the manual lacks detail on the specs of the light, this is one area where they were indeed proactive and up-front.

    That is why the review got posted this morning ... I wrote it last night in bed, but was too to proofread it before nodding off.

    I was eagerly awaiting your review of the Raptor,but could,t wait so i ordered one a few weeks ago.
    Your review as always excellent,I liked Just about everything about this light except it does not have a antiroll feature,so i made my first mod to this light using a solarforce tailcap L2-S4 which provides antiroll a lanyard hole and ability to tailstand.Now its just about perfect.

    Ring doesn't look like SS, prototype had shiny SS ring, production version has cheap alu (for me it feels like plastic). And it's too close to the back of the flashlight, I don't have big hands but I need to crook my fingers to reach it (closer to head would be better, my filgers touch "High-Mid-Low-Strobe-Standby" markings.

    And true low is very nice feature, not always you have many flashlights with you, or you just don't want turn them on and than low mode is very useful. I have Spear as well and I use it more on low mode than on high. Thrower beam is not annoying and Raptor is even less focused (wider beam+less intensive hotspot).

    PS. I.B.S. interface was the best (UI itself, not efficiency), no problem with modes you don't like

    Nice review of a nice light.

    I have to pretty much agree with you on most points. I hadn't done any tests to determine if there was battery draw with the light only turned off by switching to standby, but I had assumed so. I am glad that you confirmed that.

    My only real beef is, like you, with the sequence of modes. Blech.

    I would love this, or another, Raptor that offered the IBS for the 4 outputs. That would be the best of both worlds and I know I wouldn't be the only one chomping at the bit for such a light. Please JetBeam?

    A good point - the light does roll easily.

    Ooops - yes of course, the control ring is indeed aluminum (sorry for SS refs in the review - I have just fixed them). As for the ergonomics, I agree that slightly higher up the head might be better for my size hands as well - but I find the current location comfortable enough.

    And true low is very nice feature, not always you have many flashlights with you, or you just don't want turn them on and than low mode is very useful. I have Spear as well and I use it more on low mode than on high. Thrower beam is not annoying and Raptor is even less focused (wider beam+less intensive hotspot). PS.

    I agree with both points - a true low is a very nice feature, and I personally quite like the original IBS interface.

    My point is just that not everyone requires/wants those features in this sort of light, so I can see it fitting in with a certain niche. For a general purpose light, I always recommend one with the true low. And unlike the IBS interface, this is a flashlight you could hand to anyone any they would immediately figure out how to change modes. I would just like to see the mode sequence on the ring make more sense.

    That's an interesting idea ... something like Standby followed by 4 modes (e.g. labeled I - II - II - IV), where each of the four modes could be set through an IBS interface through the tailcap. Light could come by default pre-set with an increasing level of output and maybe strobe at the end for the four outputs. That way, it work work well for those who don't want to re-program their light, but advanced users could customize each mode to their liking.

    Yeah, I like the sounds of that interface.

Unless the switch is clicked off or the current path is broken by locking out some part of the light, this "standby" mode will continue to draw power. As such, the name "standby" is more appropriate than off.
    I will just add a warning to the you statement about standby mode:
    The current draw is rather high (2mA), it will empty a set of CR123 batteries in about one month!

Each strobe frequency last ~0.5 secs, and they loop in continuous repeat, starting with the highest frequency. Here's what a 4 sec trace looks like:
    In my (Danish) review, I got slightly different frequencies, i.e. there are probably some variation between lights. Did you miss the 20us flash that comes 120ms before the light comes on, when activated by the switch. Or is the reason for these differences that JetBeam updated the light?

    Thanks HKJ - that does seem rather high for standby, I will add a note to the review.

    I just checked your review (nice job, BTW - might have saved me some time if I had seen it before ). I see you got 5.2 Hz, 6.2 Hz, 14.3 Hz and 20 Hz for the strobe modes (I presume in reverse sequence?). Since each of those values are only 5-8% different from mine, I suspect it's probably just natural variation between our samples or our respective testing beds (mine is a simple sound card oscilloscope, so may not be as accurate).

    And good point about the 20us flash and delay. I hadn't noticed that - it is present on all modes, including Standby (i.e. you will see just the flash when pressing the switch). I will add a point to the review.

    Thanks for the great review. I have this light, and also have ordered the titanium version.

    Question: If standby is draining the batts, is that also true if the selector ring is left in lo, med or high? And, how do you turn the light off to where it will not drain the batts?

    Its one quality review you have up there!!!
    I agree with you Selfbuilt on the strobe thing.
    I've never heard of ANYONE who has found the strobe function to be useful. All users (policemen) that I've heard from about their experience with the torch's strobe function is ZERO, i.e. they don't use it

    One of the policemen who claims to have trained with the SWATs (one of the most respectable tactical units), and he said they ain't even taught to use these strobe features.

    So who uses them? The torch salesmen?


    But there's one thing that I think you may have overlooked.
    That piece of debris inside the head. That is CLEARLY is manufacture defect. Even if it doesn't affect the beam now, chances are it will one day as it gets loose.
    IMO, that light unit shouldn't have passed the QC. Was the QC implemented at all? Or did the JB people stuck the sticker on it anyway after the toilet break?

    The drain is only when the ring is on "Standby" and the end switch is on, turn the end switch off and there is no drain.

    "Reviewer's Note: The RRT-2 Raptor was provided for review by JetBeam. Please see their website for more info."

    The ironic thing is that, I think your review has more info than their website.
    I'm not trying to have a go at them, but the thing is, I found that most of the light manufacturer/dealer's officials websites always has less info than good reviews like ones that selfbuilt write.

    I think that's one of the reason why i've bookmarked selfbuild's review page, and not those official website's page

    Nice review ... nice light.

    Yeah, Jetbeams QC sucks ... my RRT-2 has only one flaw, a Cree with a misaligned die. Result is the ugly crescent halo around the hotspot. Ok, it is primarily Crees fault, but wtf is it so difficult to have a 2 second long look at each LED before passing them through to the assembly staff ...

    I'm glad you brought that up - I realize I wasn't clear in my original statement, so I've just modified it.

    What you are looking at is not the actual defect - it is a reflection and magnification of it. Just like the blow-up reflection of the yellow die from the emitter, that little triangular blip moves and changes shape as you move the light around (i.e. become greatly elongated at some angles, and disappears at others angles). In essence, what you are seeing is a distorted blow-up of a very slight defect in the reflector near the emitter (so slight, I can't see it without a magnifying glass)

    I would try to get a better shot, but I can't seem to get the bezel ring off (my snap-ring pliers keep slipping, and am I'm shredding my mouse pad to no effect ). Thanks for calling my attention back to my description of it.

    I would point out the website has a lot more info than the manual does. At a minimum, I think all manuals should at least list the light specs (including what batteries are supported).

    Great review.
    Is the focus adjustable as advertised on jetbeam site ?

    Yes, something else I meant to mention but forgot.

    The beam is somewhat focusable - you can twist the head region separately from the section with the output mode labels. In practice, all this does is let you defocus the beam slightly, as the range is limited. Helpful to allow you to achieve the best possible focus, but not much else.

    Note that mine came default at what I determined to be the best focus. So either JB is setting these up correctly, or my sample happens to be very lucky.

    Strobe is a bit slower on my RRT-2:
    18.7Hz, 13.2Hz, 5.7Hz and 4.8Hz, complete cycle 2.4s.
    Same frequency with 2xRCR123 and 1x18650.

    I was unable to detect any signs of PWM, and so must conclude that the RRT-2 doesn't use PWM to create its lower output modes. That would be consistent with the relatively bright Lo mode on the light (i.e. you typically need PWM to get down to really low outputs). I understand from Tohuwabohu's posts here CPF that the light is PFM (i.e. pulse-frequency-modulated) rather than classic current-controlled, but I don't have any other specifics.
    There are some scope graphs (all levels with 1x18650 and 2xRCR123) in my RRT-2 photo album in the Messerforum.net.
    I took these graphs with fully charged batteries.
    When the light drops out of regulation on high mode with a 18650 battery my scope shows a flat line.

    This sort of light? RRT-1 is real thrower, not RRT-2! It throws nice indees but it's more like medium general purpose light that's why it needs true low mode even more! OP reflector with 10+ kluxes would be nice too.

    Another great job Eric. I really like the looks of the Jetbeams and this one is no exception. It looks like this light has no clip which I like on a light this size. I also love the S.S. at both ends. I like the three battery options, and I agree with you, I don't need a real dim low on a light this size. I don't understand the reason for the Standby mode and see no usefull purpose for it?

    I have been trying to refrain from purchasing every new light that comes out, especially when their all Q5 or R2's. I mean how many do you need. BUT, Jetbeam is really tempting me.

    Thanks again for the incredible amount of information and your on going contributions.

    Thanks for the detailed scope shots guys. I agree, the freq is high enough to not be an issue (i.e. 25-100 KHz range, if I'm reading those scales right).

    Fair enough. I may be biased by the fact that I've been here too long - I can recall when 15K lux @1m was a real thrower!

    My guess is so that you can temporarily turn off the light without having to switch hand-positions (i.e. for standard underhand carry, to turn off you normally need to flip it around for thumb or index finger tailcap press). But this is all the more reason why it doesn't belong at the end of the sequence past strobe - it forces you to strobe everyone before going into standby! This renders it rather pointless - unless you intend to always people strobe before hiding in the dark (hmmm ... maybe not such a bad idea afterall ).

    ARGH!!!!

    This is the sort of thing that frustrates me to no end about these high-end flashlights: so many come SO close to an ideal UI, but botch it up with something dumb like this.

    I come this close to getting it. Guess the mode sequence is a deal breaker. Strobe is a no-no in my dictionary unless it's hidden like NDI/Nex or even in the other Jetbeam models (triple click).

    It looks like a great light. No need to feel terrible. Is a matter of fact congrats! Although I don't care for the standby mode I may purchase this light myself. The standby mode looks like a feature you never have to use if you don't want to.
