Modified an Original RRT-01
installed shaved LH351d, thanks to moderator007 and installed Kaidomain reflector, also thanks to moderator007
added Nyogel 767a to smooth out the ring control
the LH351d is 34% brighter (545 lumens on IMR 18350), than the sw45k (408 lumens on IMR 18350)…
LH351d is greener due to the Slider Effect (I compare everything to N219b sw45k…) lol

Nice, if you want warm I can shave a 3500K for you (also you should try to source a plain lens maybe from esslinger.com)
very kind of you to offer… will think on it
next:
Mod Original RRT-01
LED to 219b 4500k sw45k
reflector to kaidomain
control ring to Nyogel 767a
proof of light
the reason the beam is not not pink, is the photo is taken late at night under incandescent, so the sw45k looks cool blue… the Pink will be back tomorrow, when the sun is shining again
Yesterday I modified one of my Nitenumen NE01 to be able to use it in cave excursions (in Rome there are several caves under the surface)
I replaced the parabola with a 120° TIR, then I added some rubber, against small bumps, obtained from an old and too cheap binoculars. In the excursions the strap will disappear
Nice looking modding job jon_slider

I really like your comparison pics also, way better than I can do.
Now you got to try the sliced 3500k contactcr offered or a sliced 4000k that I’ll offer to send your way.

@contactcr
You wouldn’t happen to have a comparison shot of the sliced 3500k would you. I might like to try one myself.
Don’t have a beam shot right now but here’s some measurements I took a while ago:
S2+ light op reflector, 5.5A linear driver, low to high:
CCT = 3215K (Duv –0.0001)
CCT = 3247K (Duv –0.0002)
CCT = 3288K (Duv –0.0007)
CCT = 3332K (Duv –0.0030)
Below BBL with reflector is about as good as you can expect of any LED these days
Alright, you talked me into it. PM inbound.
really appreciate your contributions!
Im not quite ready for the brighter LH351d… it works great and hugs the BBL well, but atm my GreenSliderSyndrome is getting the best of me… lol… maybe its because of my cataracts that Im so in love with my pink tinted LEDs…
My favorite 3500k LED atm is the E21a in my V11r… need to order a few more from Clemence to continue my testing… there is a lot of room for improvement in the beam Im getting…
This is the beam in a V11r w stock reflector… I can live with it (because I focus on the hotspot mostly), but its not ideal
This is a beam I consider excellent, from a 219b
when using the reflector and centering ring that works for the 219b in an RRT-01 the beam of the E21a is unacceptable (led sits too far below the bottom of the reflector)

Can I grind down this area instead of filing down the MCPCB? I want to fit one of these MTN boards with secondary LEDs right on the edge of the PCB. Just worried that this may be a structural part of the host or something?
I dont own one of these, but the best I can tell from the pic it looks like a relief cut for the threading during machining with alot of meat left below it.
If you have a set of calipers just measure the thickness of the tube wall where you are wanting to grind. I usually dont like to go any thinner than .035” preferably .040” .
You can also measure the diameter of outside of the tube, then measure the inside hole diameter of where your wanting to grind. Subtract the inside hole from the outside diameter and divide by 2. That will give you the wall thickness there.

Don’t you have to bore the rim around the shelf out for a 20mm board or are you going to shim it?
What LED’s are you going to go with on the secondaries?
Beam of the Mtn board I did with “Hot Pink” secondary LED’s 
Shoot Kawi you are right. I thought it was just a thin rim but it does go all the way down to the shelf. No way i’m grinding that neatly.
However, upon opening my light to check measurements (thx moderator007) I realize that I actually have an older? version of the MTN board already in there (like this):
I guess since the XQ-E pads are on the inside I can use it after all. Probably wont look as pretty as the nicely spread out 3x secondary but it’ll do and I ordered two of the dragon drivers so I might as well I suppose.
I went with amber XQ-E
I think maybe that board might be better (looking beam if you will visually) you can run 2 XQ-E’s side by side, so more “Flood” I guess… and on center to the post between 2 main LED’s……can’t wait to see this :+1:
Is it safe to say that ive created the worst looking flashlight? We all know how big of a flop the Haikelite HT08 was, so i decided to put it to a good use and made adapter for 68mm aspheric lens.
I know, i know it looks bad and it needs some design changes, but i built this just for fun so i guess i wont change the design much, anyhow i know that i need new bezel with lens guard and some minor aesthetic changes and they are coming, but for the time being it is going to look hideous as it is 
Performance wise it is okay, 650kcd with black flat in direct drive. 1600m throw from a HT08? Ill take it
Worst looking? It’s up there with the worst of them, yes, but the performance cant be denied 
I actually like it.
Just barely squeaked a mile, gotta love that!
grin, I learned something this past Sunday… after creating similar mountains of swarf to what you show and having no experience with SS or harder metals I deviated from a plan to make a guide rod out of Titanium and went with a bar of SS I’ve had for a couple of decades. Found it in the road no less. Turns out it was hardened, very tough to drill and broke a tap off in it. Ultimately got outside threads cut at a larger M6x1 and made a matching nut for a captured spring but in trying to get the swarf off I got a piece embedded in my thumb! Curse the hardened SS shavings! So I will be taking a dental pick out to the lathe for future use… live and learn I guess. 
What? Y’all thought I only modded flashlights? 
Better in the Thumb than a micro piece in the eye —— I’m a retired carpenter— I had the Eye Dr on speed dial from micro flakes of steel from Guns that my men and I would get—Sucks
Hey but at least Titanium and Stainless doesn’t rust — Galv really Sucks
<—- grew up in a Lumber Yard, have done carpentry and cabinet making as well. I DO understand! Creosote in the eyes is no picnic either…
Riiiiight. You can’t fool us, Dale. What kinda flashlight is this going on?
Ok, but really… what’s it going on?
