@ JaredM I’ve been meaning to put aside a small budget, but not having swapped even an mcpcb always stopped me from buying more parts!It’s all downhill for my wallet now huh!!!!
I wanted to try some luxeon v2 with an DTP mcpcb due to their lower vf values, but I’m all open to suggestions! The only tints I know are xml2 t6-4c and xpl hi 6500k.Do you have anything in mind that falls in between them?I’m always looking for a compromise between runtimes and color rendering!Also,is an sst20 right for this application?

Best recommendation for you is a Samsung LH351d in 5000k. Very good output, 90CRI, and a beam pattern close to the xm-l2. If you want more throw, yet high CRI sst20 4000k from intl-outdoor is my recommendation. Depending on what cells you run, you may or may not over power them with that FET driver. The luxeon V2 is a lovely led I hear, but no first hand experience.. also, the FET driver might overpower one of those. Probably fine as a triple though.

Well, i wasn’t to enthusiastic about the M150, my particular version did not reach half of the claimed Lumen output, and the XPL2 was horrible
One light that i am very fond of is the Lumintop Tool Ti, but that needed work as well, once you go down the modding route…

Edit, yes that would be my bet as well, the Lh351 is cheap and has a good output, i might just say that it’s the successor of the XML2

@JaredM I really want to try the LH351d,from what I ve seen it’s right up my alley.I have a triple spacer too from kiriba-ru,should I try a triple with that driver?Sounds fun!

@Yokiami I’m waiting for the blf sp10s or I would already have ordered the Lumintop Tool.I want to order some 14500’s but the M150 had the benefit of intergrated charging

You can give a triple a try, heck, try them all!

A triple 351 will be super floody. For a better general use beam and much better runtimes with the FET driver I’d stick with a single emmiter. YMMV.

@JaredM I love super floody beams on an EDC but I can see how a little bit of throw is also useful.I already have a OP reflector so I should put something throwy to find a middle ground!Any reccomendations for an LED that can take the high current but is not TOO throwy?

(Also someone help me,I can’t find the configuration mode for the life of me,is it 15 full clicks from of?That doesn’t do anything and I’ve read the cheat sheet a thousand times)

It has been discussed already, but the LH351D: good output and current capabilities, a bit floody, and high CRI. As long as I don’t need a thrower, it’s one of my favorite LEDs.

Side note: it can have a slight green tint depending on reel to reel variation. I’ve never noticed it, but I’m colorblind and therefore not sensitive to it.

Another basic and slightly silly mod for me today.

I have been looking for hosts for rngwn’s high-CRI 5mm LEDs and recently I came across the first LED flashlight that I owned. It’s a fairly typical ‘shower head’ style light with 14 5mm LEDs powered by three AAA cells. It was given to my by my father but I can’t remember when – could it be 15 years old?

I replaced the original cold white 5mm LEDs with rngwn’s 3400K version, replaced the plastic lens with a glass on, and replaced the ‘driver’ spring which had fallen off.

Stupidly I didn’t take any photos of the light before the mod or even power on, but I’m sure it’s brighter now and it produces a beautiful warm flood of light. The comparison photo shows a similar (but much lower quality) generic shower head light. To be honest, this light is probably perfectly adequate for the majority of my flashlight use.

If anyone can recommend some decent quality (e.g. retaining rings rather than press fit) shower head lights for more emitter swaps I’d be interested to hear. There are a lot of UV flashlights on Aliexpress with 5mm LEDs, but you can’t tell much about the build quality from the photos.

Very Nice. Really sets off the blueish grey.

Two and a half years ago I bought the L2 host. Finally I put something in it. Sst40 with a cut and polished lens and TA fet+1 driver with bistroHD.

Don’t know what brand it is, maybe you can identify it on BG. It is of remarkable quality. 9×2300K, 3×5600K, formerly UV. Like it very much. Sorry for the dust.

This one: https://de.aliexpress.com/item/32923872041.html?spm=a2g0s.9042311.0.0.60... (click on 12 UV LED)

This might kill the LEDs. There’s no current regulator.

Ehh, just shoe-horn a single 7135 in there to limit the current. Assuming they’re all in parallel, 350 mA / 12 = 29 mA per LED. Djozz says they’re good to 100 mA, so that shouldn’t be an issue. That’d give you 10 lumens each, total of 120 lumens.

I haven’t worked out the “schematic” to see if it’s doable, but one of these

https://www.fasttech.com/products/1611/10001840/1133803-universal-star-b...

might be able to be used as a contact board. Solder a small spring or nipple to the center pad (isolated or connected to something I have no idea), got the 2 electrically-connected pads on the side (for those “bead” type LEDs), and wire up something appropriately to use that to solder to the board with the 9 LEDs on it.

Of course, insulate appropriately with plastic sheet cut to fit, etc.

It’s possible to do a cut to isolate plus, then wiring the IC, then pot everything with epoxy.

This board is interesting, too Thumbs Up

Thanks Unheard. I found that searching for ’12 LEDs UV flashlight’ on AliExpress brought up many listings for that light (or one that looks just like it), including some in different colours (blue, silver, and red). I’ve already ordered a couple from different sellers to try out.

You have to watch out for the the cheaper 9 LED version that’s in many of the listings – it looks just like the red one in my photos which is absolute rubbish.

As contactcr mentioned, some 3 x AAA lights will fit an 18650. I’ve even used a 21700 in one. However, I’m happy with the 3 x AAA in a low power light like this.

I can describe the process. I drilled two tiny holes into the plastic lens on opposite edge/sides about 1mm deep. Then used some fine nosed tweezers to work the lens off. I used dual holes in case I needed to twist but as the lens wasn’t glued, perhaps a single hole would have been fine. In any event plan on replacing the lens when done, it’s soft plastic and would be impossible to extract without damage.

The lens measures about 0.8mm thick by about 15.7mm diameter. I ordered from ebay. The sizes available were 15.5 and 16 mm and I ordered the 16 thinking I could sand it down. If I were to re-order I would get the 15.5mm to eliminate the need to sand and simple fill any difference with adhesive (duh), We’ll see when the lens gets here if its worth the effort to reduce, otherwise I may re-order the 15.5mm.

The i5T is currently in active pocket rotation and the warm tint is great for night time use but I’ve decided I might like 3-4K better.

Thanks pc_light, that description is excellent. I hadn’t realised there was a lens over the optic – I assumed that because it was plastic it was a single piece like in the later production FW3A.

Just modded the lanyards of these two lights! I think I will call these “poor-man-lanyard-without-tritium-in-titanium-bead-but-with-GITD-fob-embedded-in-paracord” the “Firefly style lanyardBig Smile Grad


Not the best looking, but it was the possible work Party

Thanks gchart Wink
Yes, I got them from CRX, I forgot to mention that Facepalm

The aqua blue one already arrived with the split ring “embedded”, while the orange one (that arrived during the OL Contest due to the theme I had in my light) didn’t have that. So I picked 2 thin drills and added a split ring to hold it to the lanyard. That’s why they are so bulky in some parts Facepalm

Great quality from CRX as ever! Thumbs Up

I know. Some have a PCB, some only cardboard carrier for LEDs. They’re all made from sheet metal. Terrible.

Solarforce!
Black L2P with T head. Luxeon V2 4000k
Blue L2P. LH351D 5000k 90cri with cut and polished lens. I did it first time with this led and I can say that this is the easiest led to cut to dome.
Both have “Biscotti” 5A driver.
I think I used too long copper stripe for blue L2P because I had a serious problem to push it. I hope I won’t have to pull it out because I don’t know how to do it.
I did this build before Barkuti described a problem with “Biscotti” driver, and I didn’t even notice it. But everything works.

Thanks!
Maybe I’ll take some pictures tomorrow.
I can’t do them on the white wall, but I’ll see what I can do in the field.
