Just received my 2020 RRT01 today and haven’t been this disappointed from a light… maybe ever? At least not one as hyped as these JetBeam rotaries have been.

- Not a 90 CRI 219C, probably 70 as comparison against several 4000K 90+ CRI 219Cs and LH351Ds shows. Same rendering as the XP-L HI 5D I have and still worse than the 80-85 CRI XHP35 HI in my Zebra. Greenish tint at low levels but this clears up past ~20% output or so.

- Ring must be rotated 15 degrees or so from “off” detent (there is very light detent at both “off” and “turbo” positions) before an light is emitted, and then it ramps up rapidly. This makes selecting a low output from off almost impossible.

- Last 1/4 or 1/5 of the rotation at the top of the ramp barely changes output, so combined with the rapid increase at the bottom end of the ramp it isn’t even close to visually linear.

- Even with the OP reflector the hotspot is much more yellow/greenish than the spill. Very “fried-egg” beam. Easy to remedy with DC Fix but obviously at the cost of throw (a harder pill to swallow with a light primarily made to run 18350 or smaller)

On the positive side:

- When the tailswitch is set to “on” the light tailstands perfectly. There is only wobble when it is off, a total non-issue. Don’t know if that’s only my copy or others didn’t bother to turn the light on before testing this. (That’s how most mechanical switches function guys! Facepalm )

- No exposed brass/visible gap at all with the stock 18350. It measures 40mm on the nose.

- Output appears to easily hit 900lm+ with the stock 18350. The benefit of lower CRI bin is a noticeably higher flux bin, I don’t think JetBeam cheaped out but would guess they had communication issues when creating marketing materials and/or buyer or supplier goofed the emitter order. I bet a swap to a good bin SST-20 or LH351D would have pretty good results if the output progression was more linear with them. XP-L HI of any temp is almost sure to function well and have a clean beam like the older models.

Overall, going to wait and hear other people’s experiences as well before deciding whether to sell the light or do an emitter swap. I wonder if the “ramp” is greatly affected by emitter Vf?

A few more impressions now that I’ve had more time with the light:

  • Must very carefully put the head on 2020 RRT-01 after a battery change. I had one o-ring get chewed up and broken when it popped out of its track during a battery change. A couple other times the o-ring popped out, but I caught it before it was damaged. Fortunately, the light came with 3 extras in the box. I have not had this problem with any other lights and it appears to be unique to the 2020 RRT-01. Perhaps the o-ring slot isn’t deep enough. This problem might be fixable with a small handfile inside the o-ring slot… but this shouldn’t have been necessary on a premium light like this.
  • As mentioned by BurningPlayD0h, the tint is slightly greenish. Also, the reported color temperature of around 3500K sounds about right.
  • The ring turns very smoothly and has no real detente at either end. There’s enough tension to keep the ring in place, but maybe not enough that I would trust it not to turn on its own in the pocket. The light can in theory be used like a 2019 RRT-01 leaving the button in the on position and just using the ring to turn it on and off. But in reality, I don’t think I would trust this to prevent accidental activation.
  • The light has no low voltage protection, so its best to use protected cells… probably the included protected IMR 18350.
  • Unlike BurningPlayD0h, I have not had any issue selecting low or intermediate modes with the RRT01. Brightness at different ring settings is a smooth ramp-up. Feels very similar to the 2012 and 2019 RRT-01, or the Sunwayman V11r. If anything, I found it easier to fine-tune the brightness since the ring turns more smoothly and requires less pressure than the 2019 version.

Compared to the new RRT-03:

  • The RRT-03 does not appear to have the o-ring issue. Like most lights I can remove or replace the head with no attention paid to the o-ring and no problems.
  • Tint and color temperature on the RRT-03 appears much better than the RRT01. Not greenish on any mode. A bit cooler too. My guess is 4000-4500K color temp. I think the RRT-03 probably has higher CRI too.
  • The RRT-03’s ring is stiffer than the RRT01 and it has firm detentes at each setting. However, unlike the RRT-01, the RRT-03 does not have the option of using only the control ring since the light is on in all ring positions.
  • The aux LED modes in the RRT-03 seem most useful for partying or maybe as a warning light while walking around. These modes aren’t that useful for actually lighting things up. The aux beam bounces around behind the optic and comes out with a dim central spot surrounded by 3 brighter lobes (these lobes are quite far from the central hotspot too… maybe a 30 degree angle off-center). If you want a red light to actually illuminate something you’re better off buying a Nitecore or maybe the Acebeam keychain light.

Thanks for your first impressions

the sensitivity areas you described do not change with an LED swap.

I agree with your very clearly stated observations about how the ring behaves, very little light at first, then rapid acceleration, then slow acceleration. This is true for all versions of RRT-01.. they all use the same driver.

I have gotten used to the ramping rate of my RRT-01. I like it better than the ramping on an HDS, which consumes the first 50% of the dial on 12 separate levels all below 2 lumens.

Im sorry to hear the High CRI LED is not very good.

An emitter swap to sw45k 9080 is a first priority for me, in all generations of RRT-01..

pretty much all my user lights, get a 9080 LED.. My old eyes see better with High R9 CRI. Everything looks more alive with high R9 CRI, food, people, flowers…

look at the R9 bars on these two lights, they render colors very differently, but not everyone uses flashlight for color, some prioritize lumens over CRI.. choices are good

pic is a link to more examples of different R9 outputs from various LED options

Did you lube the control ring, or does your feel pre-lubed? I’ve noticed part of the issue is a feeling of slight grittiness that makes it hard to make fine adjustments. When applying just enough pressure to move it there is a slight “jump” and I’ve overshot what I want, especially near the bottom of the ramp.

In direct comparison to 9050 219Cs and other high-CRI emitters I am 100% certain the one in my RRT01 is nowhere near that. Not just an issue of variation within a bin but truly not a 90CRI (or even 80 I’d wager) version of the 219C as advertised. It leaves skin, wood, cardboard looking yellowish and “dead”, vs my other 219B/C lights which have the wonderful color rendering they were long known for (+ 144A, E21A, SST-20, LH351D, etc. I also compared to).

The phosphor is a much lighter/more yellow shade than the other 219Cs I have as well which are very orange in comparison.

My RRT-01 2020 feels like it came pre-lubed.

It’s actually the smoothest turning magnetic ring flashlight I own. The ring action is smoother than in my 2012 and 2019 RRT-01, Sunwayman V10A and V11R, and my Jetbeam TCR01.

My new 2020 RRT-01’s ring has absolutely zero grittiness. I also find that I am able to make minute changes to brightness via very small ring movements with no jump. There’s no stickiness in the ring to overcome to get it moving.

FWIW

my RRT01 2019 (with 219B) is ‘somewhat’ linear after you get past the stupid strong on/off detent. There is a slight delay in the ramp on the bottom end still.

my Sunwayman V11R (with LH351D) is more linear at the low end and the upper 25% of the highest end visually appears to do almost nothing.

I suspect there are too many factors to say anything definitive though. If I was BurningPlayd0h I would re-test with a half drained battery and see what changes happen since we know it’s a boost driver.

My RRT01 2020 is in LA customs but i’ll measure CRI and report back when it arrives.

I actually already ran it on a AA Eneloop, and didn’t notice much difference in linearity. Reduced output of course but that seemed proportional across the range of output.

I do like the new RRT-01 and 03. They’re cool lights with a nice interface.

Even though it feels a little odd carrying one around since an FW3A with 18650 installed is the same size as the 18350 Jetbeam, while being much more powerful with much longer battery life.

My 2020 rrt01 has wobbly tail stand regardless if on or off. It looks designed to be flush clicked in but mine missed by about 1/2 mm. It’s a definitely wobbly tail stand.

I asked Jetbeam if it is possible to buy the extension tube separately.
Yes, it is possible. The cost is $10 + $8 shipping

Out of curiosity, I also asked about the hole in the control ring. They stated that it has no function.

That’s funny, they told me it was to put grease in Smile At least on the one I just got, it is also perfectly indexed with the back (front?) of the light, so that if the hole is directly opposite the clip, it is at the center of the rotation range.

Mine also won’t do a perfect tail stand, though it is so close when it is clicked on. My initial impression is that I think it is a high cri emitter, just not with the greatest tint. But what do I know, and I haven’t had much time to play with it, maybe tomorrow. Hopefully someone with some equipment can just confirm it one way or the other soon :).

If not already mentioned different copies have different length battery tubes. I have two 2019 versions. One is is clearly longer than the other. The longer one closes all the way and the shorter one has the big gap.

Does the shorter one has strobe and SOS?

that is new info to me
mystery solved Beer

is there a difference in markings to recognize which one is the long model?

hoping someone will do a photo lineup comparing the different variations

Best I can do but the different markings are noticeable. That’s if this picture actually posts!

No difference in markings on my samples – and a bit less than 3mm difference in length

The ones that say jetbeamworld.com must be older as it’s not a jetbeam site now. I wonder why they made it longer. Could it be to accommodate protected 18350?

thanks!

a protected 18350 is 4mm longer than unprotected

if the lights were standing on their tails, vertical side by side on a table, the height difference would be more obvious, but I can already see that the difference is revealed by the pocket clip screws.. they are in the middle of the tail lug, on the short one and not centered on the long one:

so the threaded portion is unchanged, but the tail end is longer

could you take a photo of the Four Versions of RRT-01, tailstanding side by side? Smile

thanks for the 4 model photo..
my cat also likes to investigate when I take pics.. LOL

your 2012 shares the strobe capable driver with the newer models. (based on no RRT in the serial number itself). These do not fit protected 18350, the light wont close. (I use unprotected IMR 18350, with due diligence)

the short 2019 fits protected 18350, but has a cosmetic gap (does not affect water proofing)

the long 2019 fits protected 18350 with no cosmetic gap

the 2020 fits protected 18350 also with no cosmetic gap

(please correct me if mistaken, I only own the 2012 version)

Someone had to do it, and post at least... pardon my lack of ability to make consistent wb or format a post cleanly, but you'll get the idea. 

 

219b sw45k  2020 rrt01 on the left

Vs 319c ~80cri 5000k triple in a convoy 

 

Vs  emisar d1 xpl-hi 4000k (forgot the rest of the numbers/  letters that go with that) 

 

Initial impression,  excellent of course!  Went from unusable xpl hi 6500 something or another with horrible tint, but admittedly bright.   I have harbor freight lights at work that feel ultra high cri compared to it, should've taken some documenting photos for posterity.   Went from that neat unusable light to the top of the class.  Anyone want to trade a stock jetbeam xpl-hi for emitter swap?   Is there a thread for intentionally bad mods? trashy mods? Donated donor host/ drivers welcome :p. I'll try the yang with the ying.  Wait,  isn't that called a tactical light? 

 

Last thoughts,  would still like a more robust spill and softer boundary to spot.  Without sacrificing output yada yada, that might be a pipe dream.   Custom reflector?   How to do?

 

Early on,  during the extended Corona shipping time (actually, Neal got it to me pretty fast), i had really wanted the extenders for longer batts...  but faced with reality,  they make for funny proportions,  and i dont have the button tops to use them with.  Unless i poach out of those harbor freight lights from work... but that wouldn't result in desired run time lengthening,  might go the other way actually. 

Control ring on mine is dry and pretty loose action .  Need  to experiment with grease injection into that alleged grease hole before i go Jonathan on the ring assembly with my non wimpy thread lock breaking tools...i think i see some wispy grease traces through said hole.   Lemme ask jetbeam snd i get to choose my answer! 

Wink

 

Do my pics show finally?   I hear you other newbs.  I might've learned me something (that was harder than the soldering and all that stuff).  Image hosting whathuh?

I might've made all my inappropriate pics public tho in the process.  "I gotta small gritty tool."   "Here's one of my clicky...i think i like twisties." Etc etc...  It's all too enticing for the imugr weirdos.  These flashlight titles too titillating! 

Someone told me how to lose the riffraff...it didn't take...haha... so far still entertaining and novel though.   Someone said 2 minutes after i uploaded it that my tool was so small snd cute...5 seconds later another said "at least it's hard" (ya, because it's a tool ti! so obvious,  duh! )  

Facepalm

This is what quarantine does to us.

So does the spill have rings in it or is it well focused using 219b?

Right, gotta do something other than climb walls.
No rings im noticing, unless you counted way at the bezel edge, i suppose off the ss ring. And when i first assembled without the centering ring. That was like a tie dye shirt x bullseye ..

your beam quality on the left looks excellent, almost no shadow ring in the spill. Much better than the beam on the right…

can you post the beam with the stock LED also?

I wonder what is different about the light Jchang76 modded, to produce what appears to be less of a shadow ring in the spill…

or are they the same and the brightness was just set differently for the photo?

Dang it,  i wrote a reply and lost it. 

Will check with you later after i photo the light by itself at night. 

What is changed between the three shots?

Mine do look less ringy but we'll compare.

I think the marketing strategy in addition to lumens driven,  is throw driven.   They don't care about the quality of light (well,  throw pwr does have its place)  but the numbers that can be written down. 

My smooth reflectors (3+) seem to share this effect.   The "worst" being the throwy d1 with a cree.  So add tint shift to that,  which this has little to none.
