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

The new RRT-01 showed up today. The operation direction is the same as the V11R, unscrews the same too. This one has 2 quick turns to the right and its in strobe that vary’s brightness. 3 quick turns to the right and its in sos. Simple UI. It also has detents all the way around. The detents at off and high are more resistive in motion. It’s kind of like a lock in off and high.

It experiences the same drift in the same manner as the V11R. First turn on lots of drift until warm, stable once it warms up. Turning the light once stable 360 degrees about the same as the V11R, I saw 10 to 12 lumen drift at the upper end.

In my lumen tube using a Aspire 18350 the highest I saw was about 800 lumens for just a second. Settles around 700 lumens and decreases slightly as the battery depletes.

Working on taking the light apart. More to come.

Nice! Looking forward to seeing your breakdown.

TIP: Assuming the new RRT-01 is constructed the same way as the old one, it is critical to desolder the driver wires from the star and completely remove the driver from the head of the light before twisting the two halves of the ring apart to get to the magnetic ring. If you twist the two halves of the head apart around the ring with the driver installed you will torque the driver wires and break them.

congrats on your new light!

did you just tell me that there are more than just the 2 detents at off and max, in the new RRT-01?
iow, similar to the Eye10? which btw also has the strobe…

I have an Eye10 and the detents do not produce consistent lumen levels at each notch…
now Im sad, and my wallet is happy

No real continuous variable brightness huh? This is not what I expected.

Detents all the way around, count me out then.

One of the best things was the smooth ramping. A single detent for off would have been fine.

It doesn’t really stop at the detents, its just a small catch you can feel when you turn it. If you didn’t want any detents at all, besides off and high you could sand or file them out. Their pretty small little grooves, a small ball bearing rides in the curved grove with a spring behind the ball.

16mm MCPCB?

I didn’t measure it clemence but it’s definitely not 16mm. I’m guessing 14mm or smaller. I already modded the light with a LH351D 4000k 90 cri, turned up the current, and larger emitter wires, so its back together now. :smiley:
Looked to me like it was about the same size MCPCB as the V11R, which is a 14mm.
The MCPCB has two holes that are only partial drilled so that the MCPCB holding screws are counter sunk. Changing the MCPCB would be challenging unless you didn’t use the screws and let the reflector apply pressure.

Its making 900 lumens now of high cri light. :smiley:

Fairly easy to mod, toughest part is the same with the V11R, getting the head and control ring apart, blue loctite. Wasn’t to bad though.
It does have a lot of parts to keep up with.

I like the idea of the 8 indents as it would make it feel more mechanical, also holding it where you put it.
It would also be good for helping you to know approx runtimes for example, feeling 3 micro clicks might = 1.5 hours runtime, making it less guessing for runtime.

I like the heatsinking copper to brass to aluminum & SS for drop protection.

I took several pics while I had it apart, I’ll try to do a proper right up tomorrow. I really like the light, but I’m a control ring fanboy.
I always wanted the old RRT-01 but never got a chance to buy one, so when the new one came out, I had to have it. :confounded:

Thank you Moderator007. I have one in route, should be here by the end of the week. Glad to see getting at the emitter isn’t a huge issue. Blue Loctite hasn’t stopped me in the past. :slight_smile:

I have a LH351 in 5000K and a Luxeon V2 5000K. Haven’t decided which one it will get yet. I put a Luxeon in a V11R. Didn’t have a 13mm or similar board for it so I had to make a 10mm one work. Reckon I will just reuse the RRT’s board and do a reflow. I didn’t notice any CCT number in the spec of the new RRT. Can you make a guess at what it is in stock form?

Thanks again.

Thanks 007, I still might get one out of curiosity.

- Clemence

I told you wrong Clemence, the V11R uses a 12mm MCPCB. The RRT-01 seemed about the same size.
I will try to take the bezel off tomorrow and check to be sure.

Sorry but I didn’t play with it but a few minutes until I started taking it apart. :person_facepalming:
Under UV the xpl hi is yellowish orange if that helps.

Looks promising so far. Any word on low voltage protection?

Too bad the pill isn’t made from aluminum or copper.

- Clemence

Thanks for your reports on this so far :wink:
BTW, did you take some photos on the “stock” LED beam?
We’ll be looking for some more comments on this :+1:

The pill is good ole cheap brass. I just checked for LVP, I dont know exactly what it’s doing, I put a very old trustfire 16340 in it. It worked on high for a few seconds then went into a flashy mode. It’s like 10 really quick flashes pause a half second 10 really quick again and then again then a 2 second pause then it starts over again. It doesn’t stop until the light is turned to off or the head screwed off. The battery is at around 3.0v when I pull it out and test it.

I hooked it up to my power supply and it never experienced the flashy mode even down to .7v with the current set high so it could draw all it wanted.
I’ll try the current then, set the voltage to 4.2v, reduced the current slowly, at .44a the flashy mode showed up. At .45a normal operation.
This was all done on the highest setting on the control ring. So it has some kind of protection but most batteries would be dead by the time it could only supply 440ma.
On the power supply at 1v the input current was almost 2 amps. Uses the same PAM2803 316BCG combo the V11R does.

I noticed the sense resistor on the RRT-01 driver is .05 ohms and stock reported about 800 lumens. Which when I modded the V11R, that’s about what I got using the same sense resistor. I changed the V11R to a .033 ohm sense resistor by stacking a .100 ohm on top of the .05 ohm. Did the same mod to the RRT-01 and pretty much got the same results, 900 lumens.

No photos of the beam before the led swap. :person_facepalming: Now it’s very comparable to the V11R beam, the RRT hot spot seems a little brighter in a side by side comparison. Enough to notice it. I get more excited about modding a light than I do receiving it.

A persistent blinks is good enough. Based from your description it’s not an LVP. More like a LCP, or LPP. Strange. So it’s still an interesting modification base. So far what can be improved are:

- Redesigned aluminum/copper pill. I see a there’s room for bigger MCPCB

- TIR optic

- Better LED

- Smoother rotary movement or perhaps smaller notches for more precise stops

  • GITD components or blinking flashlight locator
    As for the output, it’s already more than enough in my opinion. 500lm in 90+ CRI is my goal, should be not that hard.
