Can anyone help me out, I have one of the astrolux/Blf 17mm “Lighted’ tail switches. today I decided to change the colour of the LEDs. so i desoldered the current two and replaced them with some smaller 0805s, but, only one will light up? i have changed the polarity of the other one and even changed the LED a few times but still no light to the second LED. do i need to change the resistor values or something?

cheers

Modded a Klarus Mi7 14500 flashlight with a BLF X6 driver modded with a attiny85 and a east92 board modded with NarsilMQ8 firmware.
That’s a lot of modding. Smile

I’m afraid that requires troubleshooting yourself where the bad connection is. Did you pre-tin the leds?

Apart from a bad connection, if the two leds are a different colour (especially if one is red and the other not (green, blue etc.), the voltage difference is too big and only the red one sucks all the current and lights up.

OK, thats probably it then as one is red, and it is the only one lighting. ill try a different colour and see if it helps.

Thanks for the info Djozz

Another way to solve it is finding a way to solder a separate resistor for each led, then a red and other colour led is no problem. I did that once for this board: currently they are behind a common resistor, but if you cut the long trace that goes under the switch and add a extra resistor for the now ‘cut-off’ led between led and switch-pad (sorry, no picture but I guess you can think it out), both leds will work. The two resistors must have twice the value then, to have about the same combined resistance as before. Or you can tweak the values to have the two leds light up evenly.

Great work on the bezel, I had been planning on doing the exact same thing, nice to see someone has done it and what it will look like.

I’ll bet it took a while even with that small amount of stainless to sand off, did you start with coarse and go work up to fine, or just use one grit the whole way through?

Woo-hoo, finally unlocked the hidden beauty inside the Astrolux S42. Using one of Lexels’ S42 Narsil drivers, the S42 now has access to moonlight, turbo, last-mode-memory and stepless ramping etc.!

And since I didn’t mind a little parasitic drain (certainly much lower than the OEM dragon mode drain), I managed to keep (a red) locate me mode (as it doesn’t “breath” like original).

Suddenly the S42 is a fav again Smile

Move towards the light.

I’d wait, from what I understand they’re updating the driver in the next version. I don’t know if it’s Narsil but in any event it’ll be an improvement over the original UI.

If you don’t want to wait, you may want to get the copper head. It gets warm faster now Wink .

Would be awesome if it was Narsil. Thats what is on the GT right? IF I were to get another, it would be the stainless and copper one

My first Maglite mod will be soon made. I got a 2D led pro from a hungarian forum member as a present because I have never touched any Maglite So I decided to give it some power.

Exploded:

My plans:
Making a spacer for 4 convoy S2+ reflectors it will have 39mm material under the leds Big Smile

Design done:

Sand down the paint on top edge of tube because that will be contact negative to spacer and then driver.
The driver will be a Texas Avenger LDO 2S 21mm driver with E-switch and Andúril firmware in the bottom of spacer.
I will cut the top of the switch holder to put in a copper contact plate and I will use 2× 18 AWG wire to contact it with battery positive contact terminal through the gutted switch.
I will put in 2×26650s and spring bypass on bottom end, and they will be driven 4 pcs SST40 Leds in 2S2P led config. I hope it reach 8-9000 lumens.
And maybe I turn some heat fins on the head for better heat dissipation.

Most of this are plans but I have the leds and driver parts so soon will be made.

Wow that will be a beast of a light ZozzV6. Are you going to keep the domes on the SST40s?

Reminds me of my spark sp2 mod which has four similarly sized reflectors and is 2s2p.

Yes and I will use OP reflectors to make the transition smooth as possibble from hot spot to spill.

BLF A6 driver into Convoy S2+ (XM-L2 U2 1B 7135 × 6)

The mod took me about 20 minutes. The driver is soldered into the pill which took a little extra time. This is not for beginners. I can see a novice making a cold joint or a hot mess.

Total cost for the driver and the S2+ was $11.36. Was it worth it? Maybe. The S2+ was too bright on low. The mod fixed that. It is also noticeably brighter on turbo thanks to the FET. I have a pretty good flashlight for $11 and change.

On the other hand, I paid $17.99 for an A6.

I could swap the emitter to an XP-L with a total cost about the same as an A6. Even after the emitter swap, the A6 is going to be the better of the two.

The A6 looks a little better, feels a little better, and is a little easier to work on.

Since i don’t have an A6 i dont know the difference in quality between them. Just wanted to say that modding gives you the opportunity to make something as you would like to have it.
Modded my silver S2+ which came with the V2-1A, which was nice (nice beam for a small size fl) but i did not like the tint, also i thought it would be nice to have a pocket rocket, so ordered a XPL2HD 5000K and A6 driver, which is nice but the yellow corona annoyed me, tried an OP reflector, which made it somewhat better, but not enough. so now just ordered an XPL hi 4500K

Also changed the black switch for a silver and a silver screw-on clip, so after all, it is what i expected it to be.

It’s not a bargain anymore though Facepalm

Sure it is. Compared to a SureFire or a Fenix, as long as you don’t include your hourly rate, it still sounds like a bargain to me.

C8 build with XHP50.2 in C8 with LD-B4HV 6A driver. It's bright, ceiling bounce shows 275lux, all my XM-L2/XP-L builds have 110-120lux, so this light should have ~3300-3500lm OTF. But tint/corona is absolutely terrible! Worst tint I've ever seen, and also there is annoying purple cross in center of the beam with smooth reflector, which becomes purple spot at larger distances. 

Few build details:

LED is on mosX, and because NTC connection must be with 2 wires, NTC is soldered as in picture, other wire is then soldered directly on free NTC pad.

  

I soldered power wires in wrong direction,but i was to lazy to correct that, it works fine this way:)

^ my best XHP50.2 build is with a KDIY F8 host and a 5700K 90 CRI XHP50.2, so a heavy OP reflector and a thick phosfor layer over the led. The beam does show tint shift but it is not so obvious that it is annoying, even not for a flashaholic.

The beam of the XHP70.2 (80CRI 5000K) in my Convoy L6 with smooth reflector looks very good btw, you can tell that it is a new generation Cree led if you look for it but the beam is fine anyway.

(but if you have an OCD for both tint, CRI and beam, Cree is not for you Wink )

I have mixed different xp-ls and xpl2s under cute-3 and they always look pretty.

Yep, even on an S2, the 4C LED throws a yellow hotspot with blue spill, classic fried-egg beam.

With a TIR, it’s a thing of beauty. Wonderful warm sunlight…

In general Convoy S7 was my most used light since I built it almost 4y ago. It had XM-L2 U2 1D paired with nanjg 105c twin group with 12x AMC7135s and HE2. Today it got upgraded with blf 17dd+1 driver, AWG22 wires as well as bypasses with same wires, XP-L2 V6 3D, AR lens, brand new switch and VTC6 battery. I saw it pulling 8A and its bright for sure although tint is not up to my liking but probably I will leave it as is since I like it better than SST-40 which I also tried in it Smile .

What I found interesting is that old bypass broke even though I use blob technique. Probably because everything is very tightly spaced inside tube.

Newkie Brown used to be my favorite beer when I lived in England for a year in the eighties. Nowadays I can buy it even here in Holland, in fact I believe it is even brewn here.
