i just chatted with the Haikelite Store on Aliexpress, they said the XHP35 HI version is using the D4 bin

Usually companies won’t pay the premium price to get the top bins. For them, every penny saved is a penny earned and it adds up. Maybe they realized they need top bin and decided to buy it? Maybe.

I’d like to hear if Texas_Ace knows what bin they were using back when he was building drivers for the xhp35-HI lights.

but when TA was building drivers for them that might have still been the old version mt09rs, the D4 might have only been changed in the latest stock?

I was just wondering what they told TA they were using. It is irrelevant for current models. I was just curious. The bottom line is that you really don’t know what they’re using. You could buy a light and test each of the three emitters at a specific amperage and measure the Lumen output and that might get you in the ballpark of what brightness bin it is.

For instance if it is 30% below what a D4 bin is supposed to produce then chances are it’s not a D4 bin. If it’s within 15% or 20% then it could be a D4 or it could be a D2. It’s very difficult for hobbyist like us to figure it out for sure.

For now, we just have to go by what they say and assume it is a D4.

(I’m still skeptical because in the past they usually went with whatever LEDs were cheaper/cheapest)

have any of you tried bypassing all the springs successfully?

[JasonWW]

@scr79423

have any of you tried bypassing all the springs successfully?

Which model?

I believe it’s fine to bypass all the springs on the 70.2 version. (Edit, if it’s the new factory driver this might burn the big FET)

You don’t want to bypass any of the springs on the xhp35-HI version.

i ordered a 70.2 MT09R and im planning to bypass all the springs with 20AWG

Only do this if you are also upgrading the main FET. The stock one will die if given anymore power.

Bypass not advisable.

Is this flashlight really 25000 lumens?

[JasonWW]

@Andybibbville

Is this flashlight really 25000 lumens?

No, Haikelite exaggerated a little.

[BlueSwordM]

Yeah.

You’d need spring bypasses and top LED bins only to achieve 24 000 lumens with a calibrated tube.

The MT03 TA is a more accurate representation of what it can do with spring bypasses.

[Andybibbville]

Thank you all for the info.

@BlueSwordM

Yeah.

For those who use the original MT09R driver (not the TA or Lexel driver), it is highly recommended to exchange the SIR800 MOSFET by a better one that can be driven up to 100A (e.g. Infineon) if you plan to bypass your springs.

You don’t mean the “original” driver (that one was rubish), your talking about the current, stock driver designed by TA. That’s the one that has the weak FET.

There’s 4 drivers for the 70.2 version and it can be hard to keep track.

Exactly, that’s what I meant to say. Thank you Jason! :+1:

MT09R or Astrolux FT03?

So now I can also confirm it MCU and FET on the HL drivers for this light are faked from some chineese manufactory

MCU has not even unusual markings it has even a spelling error missing an S in the type
“ATMEL20U”
“TINY85”
“7 digit batch number”
while the original Atmel has
“ATMEL 4 digit batch”
“TINY 85”
“20SU”
“triangle”
and 3 rows batch data on the back side where the fake has nothing

I have measured the FET used on the red MT09R driver
its labeled like the original Vishay cant tell any difference
Original @10A and 4.7V Gate
https://eu.mouser.com/datasheet/2/427/sir800dp-93246.pdf
SIR800 —> 2.6mOhm —> 26mV —> 0.26W
the SIR800 has pretty stable resistance down to 2.5V Gate voltage so its a good FET for 1S lights as well

Fake
@4.7V Gate like the MCU delivers to the FET
I got 38.3mV 10A —>3.8mOhm resistance

@3V Gate
I got 165mV 10A —> 16.5mOhm

@2.5V which the original should have around 2.8mOhm as its gate voltage gets very deep till 2V pretty stable
I get only 2A with reasonable input volatge and the stunning drop on the FET of 1.1V
so here the FET has 0.55Ohm

Conclusion

the FET HL use is definately some sort of fake which wont work on any 1S driver well
with 4.7V on gate it has a usable resistance but still this FET is like the MCU fake

[JasonWW]

Thanks

So i just completed bypassing all my carrier springs with 20AWG, using x4 VTC5A flat tops, did a 35s run on max output and my stock FET is still working! 20AWG in driver spring and all carrier springs

[scr79423]

i recently got a set of the Murata version of the VTC5As, strangely i measured 2,000 lumens gain over my regular VTC5As in my MT09R all springs bypassed, I’m not sure if my regular VTC5As are fake or genuine but aged cells?

MT09R bypassed = 18433lm Murata VTC5A flat tops

MT09R bypassed = 16390lm VTC5A flat tops
