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

It arrived today, my Jetbeam RRT01 :blush:
I wanna thank to Tally-ho for selling and sending it to me :wink: This is indeed a very nice light with a true ramping UI, from barely visible to 600 lumens (specs)!
I put an Aspire 18350 on it and it will run beautifully! Maybe I’ll mod the emitter as the XML2 it has is CW and a more neutral or warm white would enhance it’s beauty!

Thanks for the suggestions of all members, and specially Tally-ho for the deal :+1:
Best regards :sunglasses:

Nice :+1:

I may “check in” with you if/when I intend to mod the emitter :smiley:
BTW, do you remember if it has a 16 or 14 mm plate? For the diameter of the head it seems 16, but I don’t want to open and close it many times before going for the mod :stuck_out_tongue:

Thanks in advance!! :+1:

The HR20 is a control ring light, but that’s about where the similarities end. The quality, lower range and ergonomics of the RRT01 is in a completely different class than the HR20. I briefly played with the V11R before gifting it, and I remember it being much nicer than the HR20 too. I appreciate HR20 for their attempt, so I bought one to show my support. Hopefully they listen to feedback and try again.

Just swapping the emitter is fairly straight forward but it is an unusual shaped MCPCB so you will need to reflow, it’s not really worth the effort filing down a Noctigon, unless you really want to :wink:
I think the Bezel will be glued too :weary:

I found some nice pictures of the light with the various bits disassembled on TLF that you might find useful :+1:

Thanks CRX for posting the pic and the link! It really is an unusual MCPCB, I don’t know if I will venture myself to open this light and eventually damage it…
Yesterday I made an accidental reflow, but damaged the plate and almost the LED, so I guess I won’t be brave enough! Or maybe I will, when I master the solder iron correctly :smiley:

Thanks again :+1:

I bought an RRT-01 and have been enjoying the variable brightness very much. I blame MascaratumB for making me spend money… lol

I do not detect flicker with my eyes, nor with my camera

It does change brightness, using my home calibrated lightmeter, by about 10% depending which way it is facing, but If I dont move, the light holds steady regulation. I cannot detect those changes with my eyes. In fact, I probably play with the dial more than the light drifts.

note the clip is on the lower right

note change in lumens by simply rotating the whole light so clip is top left now

I dont mind a 10% change in brightness when moving the light, but Im not inclined to have a Nichia installed, as my past experience produced swings of 100% with a 219c mod in a V11R

The light I received has a very nice pocket clip, that does not interfere with the adjuster ring. However, the clip sticks to a magnet, which tells me it is not Titanium, despite the claim in the product literature.

It also has the nice Orange Peel reflector,

The low modes are just amazingly low, and it tailstands without wobbling… All good things.

The tint is predictably green, typical for Cool White Low CRI LEDs

The clip on the RRT-01 CRX got was longer, he shortened it for this pic (maybe that version was Ti?). It looks almost identical to the clip on the McGizmos, and his got a smooth reflector… different runs I suppose.

===

While entertaining myself googling RRT-01 I learned that it shares design similarities with the McLux McGizmo PD:

I like to think my RRT-01 is a cross between McGizmo DNA and an HDS Rotary. Except neither of those is infinitely adjustable, and the RRT-01 has lower and higher modes than its Ancestors… :wink:

You’ve both scored some fine torches. The JB/Niteye magnetic ring lights are wonderful tools.The extreme lows are useful.It’s bezel circumference is compatible with a couple of manufacturers filter adapters. The color filters are good fun. I wish JetBeam would have continued the evolution of this design.

My TCR1, carried since 2012, only mods are a 4K emitter and a waterproof, GITD, tape disc in the lanyard recess.

That was a steel clip I shortened on mine.

Nice TCR1 :+1:

thanks for the TCR1 pic (hope you dont mind I “clipped” it), I notice its McGizmo style clip reaches the control ring.

Is the clip Ti?

Does it have the smooth reflector like this one?:

Thanks for the tip about filter adaptors too.

Here is the long clip (supposedly Ti, and looks like a McGizmo clip) version of the RRT-01, it also has a smooth reflector.

thanks for the reality info :slight_smile:

Here is the short clip version (not Ti) of the RRT-01, it has the orange peel reflector:

The RRT-01 is slightly shorter than the V11R

Trivia
The RRT-01 fits a US$100 as a tube sleeve when not using 18350
(if on a budget, the US$1 fits also :wink: )

Jon, great improvised cash stash.
Yes, my TCR1 has the first run smooth reflector. The long clip is attracted to a magnet :slight_smile: The Niteye reflectors fit , as expected , perfectly. Here is the TCR1 with a reflector from a Niteye Eye 12.

I was introduced to the JetBeam by a friend of mine in our local astronomy club. Found BLF shortly thereafter.
BLF member “Firelight2” posted excellent disassembly instructions in this thread: control ring lube?
So,a belated and sincere thanks to Firelight2. I’ve been able to resurrect a couple of these that had horrendous ring operation thanks to that info.
My preferred , at work , method of carrying the TCR1. The paracord pocket clip keeps the factory clip from scratching surfaces.

That is a wicked nice bit of kit you’ve made there!

Love that old Tekna.

Kindle, thanks. Still in use, 3 decades on, rings and all. Under its ringy, dim glow many a item has been fixed and, most importantly,many a bedtime story was read to my children. :slight_smile:

very nice light, thanks for sharing photos.

fwiw, I made a video of my RRT-01, it definitely has flicker that my phone can see, although I can barely tell with my naked eye

Thanks, I’m highly aware of flicker and PWM, especially in my peripheral vision. I can see it everywhere, in LED christmas lighting, screens, etc,etc…. even some of my high dollar test equipment displays. Can’t say I’m “sensitive” to it though. I’m a task oriented person. Flashes, rings, hues, tones, beeps,buzzes and dings and other miniscule observations rarely interfere with my ability to get things done. Also, being a lad of the late 70’s and early 80’s , I’ve got some most excellent memories that are strobe laden. :heart_eyes: :innocent:

Yes, flicker from car taillights is another area of PulsePollution, and yes, many lights have flicker that can be photographed but is not necessarily noticeable by the naked eye.

I am not in any way trying to criticize your choice of light, in fact, I want one like yours :slight_smile:

Taking photos of flicker and PWM is a personal interest test that I apply to all my lights. It is not my intention to judge, just inform.

btw, I like your glasses… lol

Lol! Great scene! We ARE all in this together! And, no, didnt take it that way at all!!
Like you, preference is generally for little fluctuations as possible. My favorite work lighting source is still a mains driven, rough duty, Hi CRI, led lamp.
Most of my pocket lights are compromise situations, I think like many view their everyday carry items. Nothing wrong with looking for perfection.
Keep a eye out on E (vil)bay, there was a somewhat recent(last year) auction that sold a like new, TCR1 for under $95.00 USD

Jon_slider, so did you swap emitter in your RRT-01 and V11R before? Which one do you like better? I would like to buy an variable brightness rotary light and mod it with a hi cri emitter.

I do not recommend changing emitters on magnetic rotary lights, because it can make the magnetic ring overreactive. The light will continue to change brightness after letting go of the dial. If I dial up and let go of the dial, the light continues to get brighter. If I dial down and let go, the light continues to drift down. I can see the change with my naked eyes.

They also change brightness simply by pointing the clip north or south, with the stock LED, depending on the orientation of the light in the earth’s magnetic field, but the change is only 10%, and I can not detect that with my naked eyes, only on my light meter.

Selfbuilt noticed this drift too, but mentioned it was not visible to his naked eye. Everyone Ive asked who owns a V11R is unaware of any visible drift in brightness. One of them, ven has a 219b mod, but I do not think he has a light meter, and he says he does not notice the drift. I believe him, it is not easy to notice brightness changes without a meter.

The V11R that I tested modded to 3000k 219c, had drift of 100% change in brightness and I could see it with my eyes. I found that unacceptable.

just to prove that a non magnetic light does not drift in the same situation:

and here is the stock drift on an RRT-01, notice the position of the clip changes


thats about a 10% change, I can not see it with my eyes, and disclaimer, that is a homebrew meter… those lumen values are approximately correct imo, Ive tested a lot of lights with that setup… ymmv
