BLF style 18650 1s thrower( poor mans Olight M2X)

Thanks for your reply. As i understand it the led should be closer to the reflector?
And will a xpl hi be good for the best throw or rather have a g2?

Correct.

XP-G2 de-domed will give you a very narrow beam with this reflector.
Maybe too tight for you to be useful (without binoculars).
I put in a XP-L HI and i quite like it like this.

I will first mod a convoy c8 to practice with :stuck_out_tongue:
But i will order this anyway so i have it ready.

The best choice for this reflector is a dded XML or XPL: i`ve modded another one today this way, with a good U4 1A and a fet driver plus everythign bypassed it came out exacly 245k cds at 5.2 amps: running with a VTC 6 battery

XPL Hi would never ever give you 250k mcds ā€¦and we are BLF-ers, lets leave Hi for CPFers pls :slight_smile:

They are using a relatively good black emitter bracked now so you can use it by default

Unfortunately the default emitter is a total garbage, not like the first ones i got

yet, the host is great, the results are exacly the same that i got with a good modded B 158

P.S
A dded XPL would give you a little bit more actualy yet it starts at 6+ amps usualy,

Is that BLF snobbery now?

More or less reality m8 :slight_smile:

As i mentiuoned this many times here, HI emitter has a sillicone burn issue on a long term base when driven at high currents, especialy < 5000k bins
Plus its a low performer .
Plus we are BLFers, its a shame not to dedome a XML or XPL in that host, or XPGā€¦

Actualy CPF way is to get a M2X and pay aditionaly 100$ for a high class modding

How much mm driver and mcpcb do i need for this light?

Mitko, have you checked the SST-40 for a thrower yet? (my test here)

Not yet djozz , waiting for them to arrive( ordered them from Arrow)ā€¦ i suspect that Luminus are using Cree coresā€¦ as you know Cree are selling massively cores onlyā€¦
Yet, a well driven U4 1A beam profile looks even better than the default Olight M3X one with the same intensity

I had a talk with the seller( a nice chinese woman as it seems) , however she speaks only business english, she understands only about quantity and price per pc and cares not for hosts

P.S
The only Eu led emitter factory using mainly Cree cores too.

Its 40 kms away from me so i visited them many times , they do some OEMS for Bosch, Phillips, even Cree! I wonder how they stand the CN yet they do, at least for now

What bin did you order ?

The only one they have 2 weeks ago is P2-AA-VL, i guess its more or less 8000k or something and thats kinda higher K that i needed actualy but i got only 2 for the test

They claim 1800+ lument at 5 amps, thats more or less like a V6 emitter

I saw lately that KD offers them too

I understand your opinion, but iā€™m driving the XP-L HI (V3 1A) on 4 Amperes, which makes it a fine light that will have maximum output for a good part of the charge of the battery.
It doesnā€™t get hot either.
Can you say the same?
Probably not, but thatā€™s not important to you, you want the highest Candela readings from a single 18650 light.
So, to each their own, right?
No need to be snobbish on BLF, thatā€™s what people dislike about CPF, donā€™t you agree?

17mm driver.
MCPCB depends on how you prefer to build up the light.

Ofc i can! Any U3 or U4 at 4 amps will have at least 20% better candelas, better beam profile and i am 100% sure that it will run cooled than your HI or any other HI emitter in existance.
About dding it, well, i am pretty confident that everybody can do it, if someone cant: msg me , or those lovely blf ppl arround that topic would gladly help at no cost.

PPl dislike CPF cause it was all about Surefire( the one and only), flashlights under 100$ are crap, no reason bannings and other stuff of that ilk

Once again, thats the reality, the BLF way, the cheaper and more reliable / productive wayā€¦and its fun.

Exacly as modding that host, yes its ugly and cheap yet the results are great

Actualy yes, on second thoughts there are ppl that demand only 6500k+ ā€¦then using HI is reasonableā€¦.i did that on my first host actualy, quite forgot about that :smiley:

Well, i have no SureFires or Sparks or other overpriced lights.
But if i want to run a XM or XP LED on 6 Amperes i want to run it on 2x 18650 (or 26650) with a buck driver like FX-30.
For a single cell the VF is too high at those currents, so the party is over after a short while.

But okay, maybe the XP-L Hi V3 1A was not the most exiting choice for this ā€˜new BLF classicā€™, but i had one lying around so i put it in there. :slight_smile:

Bedankt voor je reply;) i want the led to be close to the reflector but what i understand is you need to fill in the space with copper or other conducter. Can i just take a 16mm copper plate and drill two holes in it for the cables and put a 26mm mcpcb on that plate(with thermal paste)?

Ok. You know that 16mm mcpcb build guys with drilled reflector from this thread? I checked again with new lux meter (with fc fuction, 5 meters, 5 measurings) and average was 282kcd.

Now I will add 11,4% difference Djozz got in measuring same dd emitter and same budget lux meter as mine + compared to professional light meter and final result is 321kcd (if I calculated right :question: ) for old xpg2s42b in Supwildfire reflector.

That is not bad at allā€¦ I finally have piece of mind :innocent:

So yesā€¦ 240kcd of new production xpg2s42b that some of you guys got with fet driver now seems realistic to my previous results from aspheric lights(25-30% difference among new vs old one) and if I will do another batch of this Supwildfire(Mitkoā€™s thrower) reflectors I will do them with new s42b. Why? Larger beam and only 3,6A current draw with fet drivers so you can enjoy turbo mode for a longer timeā€¦

LI, I just purchased one of these lights with the intention of modding it similar to your 16mm one. In short, you

  1. enlarged the hole of the reflector to fit an entire 16mm mcpcb
  2. stripped a 16mm mcpcb and adhered it to the pill to act as a spacer
  3. adhered the LED on a 16mm mcpcb on top of the spacer

Any other mods? And tips on cleaning the reflector after drilling - compressed air, rinse, etc?

Now just to decide between a new XP-G2 (I donā€™t have any old ones), a DD XM-L2 U4, or DD XP-L V6. Hmmā€¦ decisions, decisions.

Reflector cleaning? You know about those special fluids for cleaning LCD TV? They usually come in set with fine microfiber rag.

So after drilling use compressed air (i have air compressor), after that spray it(5-8 times) with LCD fluid and after that blow with compressed air again. Now it will be dry but now use spray (1 time) with lcd fluid and then use microfiber rag to clean reflector out (put rag and press it firmly into reflector and just do cw or ccw spinning of reflector to that rag). It will be shiner and better than stock. Use same method for main top glass cleaning.

I added thin o ring under upper reflector edge and pill is copper tapped.

I found desired focus with fine pill ccw screwing and with mentioned very thin oring(probably not needed) under reflector upper edge + eye centering method which can be trickyā€¦
I hold light firmly with benchvise (but you could firmly hold it with right hand) while i fiddle with reflector with left hand and when I center the hotspot that it looks perfect to my eyes on high ceiling(low mode of course) than I just hold it on that position and super glue it very thinly on several points of reflector. Fine tipped super glue helps here.
So once when it is locked with supper glue additional press of glass and bezel will tight it up even more. Reflector spinning canā€™t happen with this method cause reflector is locked with super glue.
You may use your own methods but if you did this way and if you messed something with glue just use hot air gun (short time around each edge) and glue will crack; clean and you can start again.

New XP-G2 should give you around 240 kcd(depends on light meter you have :slight_smile: ) and only 3,6A current draw(new xpg2s42b I have at home) which should be good for FET driver combination.
Longer runtimes in turbo mode are desirable in single 18650 lights right guys?

Edit ā€œstripped a 16mm mcpcb and adhered it to the pill to act as a spacerā€
No. I added it for better heat transfer. You donā€™t actually need that. So it is not a spacer. It is probably even easier to set focus without that. Use thermal glue(artic alumina so no room for mistakes here) with hard press and you should be fine with heat transfer even without additional chunk of copper.

I wonder why you pll make your life harder :slight_smile: Just order those lovely Manker( thanks m8 for the bangood link) MCPCBs and be happy.

luminarium iaculator

We have new breeds of those XPG2s now m8, they are better than the first wave ones, yet they cant compare wiith the good old ones
