Xpl Hi 2850 80 CRI

Another addition to my family of multi color lights:

Again a Convoy S2+ but a bit different from my last multi color build. It has the same BLF-X6 driver, modified for 4 channels and OTSM, with my ramping color firmware. But this time I wanted some more cell capacity so I decided to build a 18500 shorty. I couldn’t shorten the pill as much as other modders did, since I need the full space of the pill for the additional D882 transistors which drive the color LEDs. Also I didn’t want to glue or solder the driver into the pill (which would save some space) since I have to open it from time to time in order to update my firmware.

So I sanded as much as possible from the front of the pill but let the shelf there. Its thickness got reduced though, it is about 0.3 mm now. I also sanded the back of the pill including retaining ring to gain some more space. Instead of the driver spring I used a sanded brass button. Another bit of length I won by sanding the retaining ring of the switch PCB.

Despite this efforts the 18500 cell (although only 49 mm long) is still too long for this shorty. So I 3d-printed a spacer which I put between head and battery tube, with a height of about 2.8 mm. Now everything fits nicely and the cell flushes with the end of the tube. I’m thinking of replacing the printed spacer with a copper one, a piece of a common 24 mm copper tube with a wall thickness of 1 mm should fit perfectly.

The used LEDs are a very nice 92CRI Nichia 219C which Kaidomain sold a while ago, and a red and a green Cree XP-E color LED. Although I intentionally used thin wires the current draw of the Nichia is still pretty high with about 7 amps. The high capacity 18500 cells I use for this light are rated for about 4.5 amps continuous current (6.75 amps peak) so I configured my driver to limit the output.

These are the D882 transistors which drive the color LEDs with pull down and base resistors, insulated and glued into the pill with flexible thermo glue:

Sanded pill and 3d printed spacer on the tube:

Done …

I swapped a 519A in a SS Enogear and found it way too floody.
After gently pulling, the whole and complete dome came off, not leaving any residue on the glass of the LED where the dome sits on.
The tint is perfect and the hotspot is smaller, but way more usable.
It clearly shows signs of the dedomed LED, where the hotspot is not round and not square, but i like it!

Any pics Yokiamy? Curious to see how your 519A looks after dedoming.

I modified my LH351D 3500K T2 by installing an AR lens and a lighted switch. Of course I took everything apart and “fixed” some things along the way.

When I went to solder the LED, I noticed that the MCPCB didn’t sit well on the shelf. The snap-off spot was hitting the side of the shelf. So I filed it down and then it fit no problem. I like how the 1mm x 15mm MCPCB has little protrusions that fit into the other 2 holes of the shelf so it doesn’t rotate when the reflector is installed.

I noticed that there was a gap between the driver and the retaining ring. The driver was too wide to fit inside the groove of the retaining ring. So I sanded down the perimeter of the driver to make it fit.

BUT, when I went to install the driver there was not enough threads left in the head to tighten it. I guess that’s why it was left that way!

So then I made a spacer from a spare retaining ring to fit inside the T2 ring and that resolved the issue. And I think it looks better without the gap.

The lighted switch was a little bit of a challenge since the new Kaidomain clear silicone tailcap was slightly different than the original black one. When I first installed it, it was hard to turn on the flashlight since the button was too far away. So I sliced the tips of 3 switches and superglued them onto the new switch. Now it works perfectly.

The mixture of purple and green 0805 LEDs makes a nice light green color and draws 0.09mA.

I like the tint and beam of the “U6” binned LH351D LED which appears accurately to be under the BBL.

Nice mods NeutralFan, I like to finetune my everyday use lights too, but even nicer pictures, those will help other modders a lot!

Not the best picture, but from left to right, 519A dedomed, 2700K SST20, original Neutral White (XPG2 ?)

NeutralFan · 2022-03-01T01:12:40.000Z

Looks good Yokiamy. I was actually curious to see how the 519A LED itself looked after you dedomed it.

NeutralFan · 2022-03-01T01:22:56.000Z

Thanks djozz!

I remember reading about your T2 mod that also included a lighted switch many years ago: What did you mod today?

Verodin · 2022-03-01T19:07:23.000Z

Simple Sofirn C01S emitter swap. Replaced the SST20 4000K with a 219b 3000K. Pretty happy with the result.

Stock vs swapped

Thrunite Ti3 V2 mod to dedomed 519a 3000k, w pebbled Tir

I pulled the dome off right after the reflow, while it was still hot… that worked well, came off clean and left the glass shiny. The 2400k Duv –0.0036 looks like a delicious strawberry color.

^jon_slider: i like the color!

James_C · 2022-03-02T06:46:52.000Z

jon_slider, what TIR did you use on that? Got a link or specs? Thanks.

^jon_slider: i like the color! :heart_eyes:

thanks, definitely a fun color

in practical terms, its kind of extremely warm… not sure I have much use for it, but its fun to play with

This is how it looks in a Tool AA Cu, dedoming has never been so easy, just gently pop the dome off!
I really like the tint now the end result of dedoming Simon’s 4500K 519A its somewhere around 3600 K.
It outperforms a 219B and even a 219c for sure.
With dome on, it is very floody. Now its a bit narrower than a 219c, however an SST20 is still more concentrated.

Today I modded my Convoy 4x18A.
I bought few SFH55 leds from Pioneman Store and spare driver from Convoy flashlight store.

There seems to be some design changes on Convoys driver. Right one is the original. Left one is new. I modded it so that it should produce about 25A.

I also added extra 22awg wires. Screw holes are different on Pionemans mcpcb. Well, I just have to screw bezel tightly.

And here it is. Even original centering piece was same, that Pioneman provided. It’s bright, gives plenty of flood and quite a good throw. Tint is surprisingly good for such a monster led. Neutral even on low and if I must guess maybe 5500K. I’m very happy how this turned out.

Thanks for the pics! The dedome looks very clean. May have to consider that for my next flashlight. I don’t want to dedome my existing 519As since I like them a lot as is.

Verodin · 2022-03-03T16:17:22.000Z

So many positive 519a dedome stories and those mods look so good… really need to try this. Heat it up 1st or will it pop off fine at room temperature?

Yokiamy · 2022-03-03T16:26:28.000Z

I did it at room temperature, just after assembling it.
Gently grab it on the side and peel it off like a sticker.
