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

and flat white too?.

Thanks! You did a great job. I have a Dremel and some bits that can cut metal, but I don’t have an apparatus for ensuring a straight line. I think I’d likely go the route that Gunga took, to use 1.5 mm. I’m not sure there’s a 1.5 x 6 mm out there, but if so it would be interesting to combine the two. Since there would be a definite delineation between the 2 vials, would be an opportunity to do alternating colors within same line.

It’s a triangle there is no inside and outside

I always found the RRT01’s low-mode efficiency a little disappointing. It does the lowest levels I’ve seen on any flashlight, but its power use is unusually high. If I recall correctly, 9.7 mA is enough to run my D4 at, um… well, I suppose I should just measure it to find out. … 2.8 lumens. And at the lowest mode (~0.2 lm), it’s only 1.7 mA.

So with an 1150 mAh 18350 cell, the maximum runtime on those two is about 5 days vs 28 days.

Agreed. The light could really benefit from one. I had some TIR’s from Convoy’s Ali store. They are bit too small in diameter and a not quite tall enough. I made one work but it’s not an ideal fit. A friend found some TIR’s that are a few mm’s bigger in diameter and height. I will see how they fit when they get here. For now DCFix has made it quite enjoyable but am looking forward to trying the larger TIR’s.

I agree that the beam on the RRT-01 is ringy, when Im using N219b
the reflector sucks… :wink:

My bet is that Clemence will build a centered group of Four E21a, so the excess power issue will be solved
And I bet he comes up with a TIR that makes a perfect beam…

Regarding the trit slots issue with the new RRT-01… one option is to just use Two 1.5x5, and as xevious suggested, use that as an opportunity to mount 2 colors per slot

about clips:
Im seeking one of these short clips, if anyone has one available please PM me

or if you know a source for them, please share

This is the difference:

the long one comes on the present version of the RRT-01, and one of the earlier models,
the second run of the earlier model had the short clip, as pictured on my RRT-01 above, and on the Eye10 TiC

btw, Eye10 TiC does NOT fit my Keepower 1200mAh, that works fine in my RRT-01

Congratulations! That is a grail light.

nitpick:
The TCR-1 comes with a long clip… it interferes with the rotary ring… not acceptable to my snobby self:

The 2mm wide trit vials fit fine, no grinding, I measured around 2.25mm I think factory opening. Its the length of the 2x12mm trit vial that’s too long. I ground the ends a little to fit and went ahead and ground all the way down the slot to expose the bare aluminum, I was hoping this might help the trit illumination reflect back up and out, instead of just hitting the black anodizing. The ends are the only thing that needs ground if using a 2x12mm vial.

Rings, oh so many rings!

Can you link what type of bit you used to do that? I have a dremel but dont use it enough to know what 500 bits work best for what purpose.

Great to know you didn’t have to bore out the width any further. So it’s not just width but also depth that’s sufficient to fit the 2mm wide vial while still remaining below surface? I agree exposing the bare aluminum might actually help just a little with reflecting the tritium light.

I think I got mine on ebay but this one is exactly like mine by the dimensions they give.

1.5mm cutting diameter 4 flute 5mm flute depth with a 3mm shank ball nose. I don’t use dremel stuff because their not as good as of a bit or end mill made for a actual mill. I have a mill so this works for both purpose for me. These last for a very long time, carbide is good stuff. I have had this one since this project here.

I just found more info in that thread. Those pics contain the part number and show the actual bit, the one in the link above doesn’t show a actual pic. You really wouldn’t have to have a ball nose just a 4 flute end mill with the dimensions above.

If you could find a 2x10mm trit, it would drop right in, add glue and done. They make that size, It’s just no one can find them for sale.

I looked up the part # and found one on ebay. Should be exactly the one I used, you’ll have it for years if not mistreated.

A 2 flute will cut faster but leaves a rough finish. A 4 flute will cut a little slower but leaves a machined finish. Anything with a 1/8 shank diameter should work in a dremel. I have a Proxxon that has a collet that excepts a few different sizes but 1/8 is very common.

Try Jerray at Aliexpress, their carbide products are very nice at cheaper price. Not the cheapest for AE standards but definitely vetter than the majority there.

There’s a $3 off coupon for Ebay. Min purchase 3.01 or something. Good for stuff like this

thanks for the great info and pics

those NonAnodised slots would look even better with the whole light stripped:

I wonder how it would look if a 1.5x6mm trit was used instead, without removing the anodising in the slots?

anyone have a photo, even just the shorter trits in the stock anodised slots, with no glue yet?

I think I prefer anodised slots, on anodised lights… here is a visual:

That bare aluminum unpolished RRT-01 2019 looks soooooOOOO pretty! :heart_eyes: :heart_eyes: :heart_eyes:

here is the info on the old model… Im guessing it has not changed, but others will need to confirm…:

I think this means new model parasitic drain is half as big as before:

Im confused by figuring out an apples to apples comparison… selfbuilt says 55uA on 750mAh LiIon lasts 2.9 years, for the old model

djozz says 27uA on 1100mAh LiIon lasts 4.5 years, for the new model

seems the new model drains half as fast, yes?

if I used djozz values and reduce the battery to 750mAh it comes out to 3 years, essentially the same as selfbuilt

which confirms Clemences observation that selfbuilt mistakenly calculated runtime to a 0volt LiIon battery, while it appears djozz correctly calculated to 50% drained…

am I on track?

fwiw, Ive tried using a super low level as a locator on my old model RRT-01, overnight, and it seemed to use power way too fast.

so this makes sense to me:

and for that reason I now use a glow ring on the tail of my old model RRT-01 that has no trit slots. I can see it fine, when I wake in the dark, even when I do not bother to precharge the glow when I go to bed

thumbs up on glow tape for old models

here are my Eye10 and old model RRT-01, my cat always wants to be in my photos :wink:

and thumbs up on trits for the new RRT-01:

For the new RRT-01, I think I could be happy with 1.5x6mm trits, with intact anodising.
What do others think?

At least use 2x6mm unless you have a ton of the 1.5
