WTB: Jetbeam RRT01 – Any place to buy it?! + [RRT01 2019 discussion]

as long as you dont copy Clemence and tailstand a high discharge unprotected 18350 in the new model, which has a higher draw than the Original…

I disagree, I just tested and stock RRT01 left uncooled was extremely hot. The base of the torch farthest from the head was too hot to touch. You’ll get blister if you try to touch it to more than 2 seconds. It also melted my Vapcell wrapper. Tripped the battery overheat protection too.

EDIT: and this is lower output RRT01 at just 770lm OTF measured

[Clemence]

Guess I haven’t tried tailstanding it long enough yet then.

Yikes Clemence! looks like this light definitely shouldn’t be left tailstanding on max!

Last night I went and modded my old RRT-01.

  • It had the original driver from my TCR-01 in it. The driver unfortunately was damaged or defective as it would periodically flash. I replaced the driver wires with 22 gauge wires and stacked a 51 ohm resistor onto the sense resistor. Unfortunately, none of this fixed the occasional flashes.
  • Even worse, the light now has a new problem. When I turn it on max from off, it will tend to turn off on its own after less than 30 seconds. However, if I stop the ring a few degrees before it locks into max turbo then that problem disappears. I wonder if the magnetic sensor’s calibration is somehow off-target.
  • I also replaced the emitter I had inside with a triple XPL-HI and Carclo 10507 optic.
  • It’s quite nice now if only I could fix the turn off and blinking issue. At a guess maybe 1200+ lumens at turn-on with an 1100 mAh Aspire 18350 inside (based on very approximate ceiling bounce test, and on how quickly my hand heats up when I shine it on it point blank).

The issue with the light occasionally blinking on and off only happens once every 30-seconds to 2 minutes. I can live with that. But the turning off issue is no good. I’ll need to work on a solution. Some possible fixes:

  • Salvage the driver currently in my Niteye Eye10. That light currently sports the original RRT-01 driver. It works fine with no blinks or issues… but the output is low. Perhaps the resistor mod will up the output hopefully without destroying the driver; or
  • Add a stop inside the ring to prevent the ring from traveling the full 120 degrees. A few degrees less turn should fix the issue without visibly reducing max output. If I choose this option the stop would be a bit of copper sheet cut into a small rectangle or square.

To anyone doubting this small RRT01 can’t be that hot, here’s the evidence:

Out of curiosity:
The pressure caused by the heat bulged the safety switch outside, breaking electrical contact path. Drilled, there was small “poof” sounds along with pungent gas fart and little liquid released, the is now membrane relieved back inside. Now the cell works normally without any (safety switch), but I don’t think it’s safe to use anymore.

[Clemence]

Looks like definitive proof Clemence.

I haven’t opened my 2019 RRT-01 to compare the driver to the old RRT-01’s, but I suspect they are probably the same design, but with a bit more current going through.

Back when the original RRT-01 was released, outputs were a lot lower and temp sensors on flashlights were rare. Today, outputs are higher and temp sensors are more common.

It sounds like the driver simply hasn’t been updated with a temp sensor or low voltage protection. That’s too bad.

It’s still a great light though, but just be aware when you use it that this one is lacking some of the safety features found in other lights.

It doesn’t have LVP because it designed to also work with CR123. Protected 18350/16340 and temporary max mode are mandatory for this RRT01.

[Clemence]

I don’t think a protected cell is mandatory.

Just don’t overuse the light or leave it tailstanding.

I mean for safety measures. Keeps out of reach of children too

definitely!

For Children, a High CRI HDS is safer than an RRT-01, because
HDS are not 18350 compatible,
are limited to 200 lumens,
have a 33% auto step down at 40 seconds,
and auto shut off at 3.0v

.

Preposterous Proposition Warning:
A resident of the State of California has determined that the RRT-01 is not suitable for children.
Responsible use of 18350 LiIon flamethrowers requires an “intelligent” adult operator.

I don’t think I’d want to hand a child a nearly $300 HDS flashlight either.

Safe for the child maybe. Safe for my wallet no!!!

Child can make do with a $3 light from the local store.

No high powered flashlight is safe for a child. All they need to do is point it at their eyes and try to brave the light… leading to retinal damage.

For anyone interested, here is my review of the RRT01

outstanding review, thanks for the great photos too

and now Ti ala CRX

Laissez les bons temps rouler!

Differences in the Original RRT-01 and the New Version with Brass pill.

  1. The brass pill makes the New Version 1 ounce heavier and 1/8” fatter.

2. No strobe on Original RRT-01. Yes Strobe on New Version.
3. New Version pocket clip is long, past the control ring. Some Originals got short clips, and they can still be bought.

4. New Version is set for higher max power draw.
5. New Version fits 19mm Carclo without modification to the diameter of the optic. Original requires customizing the optic’s diameter.
New Version RRT-01:

Original Version RRT-01:

6. New Version is XP-L, Original is XM-L. They have different reflectors, the Original has rings in the spill beam.

Original RRT-01 / TCR-01 did not require any modification to the Carclo optic to make it a triple. The optic fits perfectly. However, the edges of the star do require a little filing down.

Are you sure about that?

I stand corrected.

Based on that photo I opened up my TCR-01 triple to double-check the optic. Looks like I did modify the optic after all so that it would fit.

However the modification to the optic was extremely simple. All I did was file down about 1/4 to 1/3 of the outside of each of the 3 legs. Basically 5 minutes with a small handfile. None of the rest of the optic needed modification… just the legs.

Yeh, that sounds about right :beer:

I wasn’t sure if maybe the rrt-01 or the optic might’ve changed slightly.
