Thanks you!

its not on stock

 

PLEASE NOTE
i do not work in "reviews, deals and codes" for the time being
maybe M4D M4X will return one day, but until then:

Has anyone received these lights yet? I’m looking to order one from Fasttech and can’t seem to find any reviews about it.

I was going to attempt this group buy but the price is better from FT….

Maybe I’ll review it when I receive it?

I’m most interested to see the possibility of removing some material to fit 21700’s and also reflowing warmer led’s (Specifically XHP-35Hi’s).

I’ve ordered a while ago from fasttech (xhp50 sand) and I’m quite happy with it. It is awesome powerhouse and beautiful light. Only thing that bothers me little bit is color temp, I like 5000K and lower. For xhp35 you would must change the driver because it’s 12V but I can imagine that with 4x xhp35 4000K, the beam would be just awesome. If you can do it, please share the results Wink

Awesome to hear, and I think a lot of us feel that way! I’m most happy at 4000k.

I actually didn’t realise this doesn’t come in a 35Hi version.

Maybe they are already using 12v xhp50.2 or they are wired 2S2P. Would you know what type of driver? I’m gonna be looking towards mtnelectronics for a replacement, maybe SRK driver will fit?

It's a FET based driver. I believe it's two channels - a small FET (plus some circuitry) and a double large FET. Thought I posted pics, maybe not yet. I'm still working on modding mine - it's a pretty decent quality small SRK style light (3 batts), stock with the quad XHP50.2 3V's - so yes, its for super high amp 3V LED's with the MCPCB designed for XM footprint LED's (XP-L2, SST-40, XHP50.2, etc.).

Here's some detail shots of the driver. I don't know who designed it. It's similar to a high amp TA driver but instead of using a bank of resistors for the low channel, a small FET is used. Of course on this driver is the support for USB charging as well. The MCU is our beloved ATTiny85 to run Anduril (or NarsilM). The two big FET's (Q1 and Q2) are in parallel, and the Q7 I suspect is a small FET with at least 1 resistor connected before it.

 

I busted my switch PCB and that's what I'm stuck on - trying to replace it. They used a ridiculous amount of nasty glue on the switch PCB. Like to keep the USB charging LED indicators but I don't have a dual LED control switch PCB -- wish someone had one. Might have to simply repair it but need one of those dual LED parts.

 I'd also like to re-flash Anduril but there's no info whatsoever about the exact Anduril config they used. Could experiment -- the thing I mostly need to know is how the config the ramping table for the low channel.

I ordered from fastech and they messed up my order. Sent me the 9000 lumen version instead of 5000 lumen. I then ordered the 5000 thru this thread’s link from banggood and they sent me the correct one. I then ordered the 13000 lumen version from here also and after waiting for 2 months banggood has no idea where it is, no tracking number shown. Anyway between the 5000 and 9000 I’d definitely go for 5000. The lumen level i measured and it’s about right for both but the 5000 version throws farther,( although I’d like the hot spot to be larger, but it throws slightly further than sofirn q8 ), lasts longer of course, and visibly the difference in luminance is not that evident believe it or not . The only thing I don’t like is how wide the overall angle is, I hate blinding everyone on the side.

Thank you! The 3V setup makes much more sense since they can use the same driver, you’ve shed light on that for me. It also makes sense then why 5000k is the lowest color temperature they can offer.

You’ve been so helpful already, I don’t mean to bother, but what diameter do you measure that PCB to be?

Also any chance of cramming some 21700’s in here? I would be willing to mill out some material (if it’s there…that is.)

It’s over my head but i’d love a battery bank function in this light, does that seem possible to add? I’d most likely have to disassemble a light with that circuitry already to learn about and borrow components.

Good luck with the switch replacement, and it seems tracking down the firmware can be quite difficult.

Since they only offer SST-40's and XHP50.2 3V's, yes, the tint offering is limited.

Can't measure the PCB diameter right now.

I'd say the chance of fitting in 21700's is slim to none. I just don't think the diameter of the battery tube could handle it, regardless of the milling work. A triple 21700 might be as wide as a quad 18650 setup. Also not sure the batt+ ring on the driver could fit 21700's either, assuming you get button top 21700's or mod them yourself. Also there would be problems with the length. Haven't check the dims to be sure of this - will do when I get a chance.

Tom E can you take compare image shot of Haikelite HK04 vs Sofirn SP36 if you have it. I am interesting to view size differents between these lights.

Sorry, got some issue goin on. Maybe today I'll get a chance - yes, I got both but the HK04 is taken apart but probably could still take pics.

Thanks in advance Smile . If you can’t take picture of them can you measure body dimensions of Haikelite HK04.

Here it is, measurements below:

Dims (mm)   HK04    SP33

Length      139.1   128.0

Tube width  45.9    44.9

Head Diam   56.1    49.1

 

The HK04 was a struggle to get out the switch, scratched the light shown above. Plan was to sand out the scratch by making the flat surface bare - might come out look'n good that way, not sure. The HK04 sure is a better look'n light with the SS bezel and style. Extra size is a + thermally, - for carry.

Not sure if this link will work to my photo album on the HK04: https://app.photobucket.com/u/TomE2012/a/420c14e6-a1fb-47dd-b4b0-9e1a68955961

PhotoBucket had a recent upgrade and totally screwed up my pics - counts are wrong, pics dropped, pics duped, etc... I restored the HK04 album but uploading is very, very slow.

Thanks TOM E for great post Thumbs Up
I just ordered SP36 host and MCPCB and driver. When they received I can measure diameter of it.

(sorry, this is an auto-translation)

HaikeLite HK04
Product weight: 370 g.
Size: 14.00 × 5.60 × 5.60 cm / 5.51 × 2.2 × 2.2 inches
Emitter CREE XHP50.2, Flux: 15000LM, Range 750m
Emitter Luminus-sst40, Flux: 9000LM, Range 850m
Emitter CREE XP-LH, Flux: 5000LM, Range 950m

There is very little information on this flashlight, I did not find a detailed review with an examination of the operating modes and operating time.
Interested in the CREE XHP50.2 model.
Tell me what is the maximum operating mode of the flashlight in which it will not turn off from overheating and how long this mode lasts.
As far as I understand, the flashlight is similar to Sofirn Q8 Pro (4×18650) only on three batteries.
You can ask to compare HaikeLite HK04 CREE XHP50.2 and Sofirn Q8 Pro XHP50.2
How are things going with the heatsink, is there stabilization, in what parameters is HK04 (weight 370 g + 3×18650) better than Q8 Pro (400 g + 4×18650).
Is there a noticeable difference between (6500K) and (5000K).
Should you buy the HaikeLite HK04 CREE XHP50.2 or is it better to buy the Sofirn Q8 Pro (the cost is almost the same).

Little late, but link to my current shared Anduril 2 .HEX file for the HK04, with notes changes, manual, source code in a .RAR file:

   google drive share Anduril2 HK04

Both are good quality lights, depends on individual choice. Any light of this size with 4 XHP50.2 3v's will be hot in seconds, not minutes. On turbo, expect a quick drop from temp regulation - it's too much power. Maybe if the light was 4-5 times bigger with tons of surface area to assist cooling, maybe then it would last a couple minutes. Obviously the solution is to run it at a lower setting, then it can run a while and both lights do a good job of regulating from Anduril or Anduril 2.

5000K is not available, hasn't been for a long time now, 1 year or more, so nothing to compare.

I have tested both the HK04 (4x XHP50.2) and the Sofirn Q8 Pro (4x XHP50.2)

I use high-drain batteries to test (for the Q8 Pro, I did not use the Sofirn 3000mAh 18650 batteries which are not as powerful as higher-drain type 18650 batteries).

The Sofirn Q8 Pro is brighter compared to the HK04.
(I don’t have a light integration device for measuring lumens but just doing the same ceiling bounce and taking a lux reading, my Q8 Pro register 1400+ lux on Turbo mode (at turn On) whereas the HK04 gets only around 1100 lux (at turn On)

Thus the Q8 Pro is brighter in actual than the HK04 — I think the main reason is having 3 batteries just cannot power 4x XHP50.2 to the max levels, compared to having 4 batteries.

At closer distance, it’s a bit difficult to compare brightness since both are very bright (the Q8 Pro having a bit wider area of light)
