Trustfire AK-90 (12)XML-U2 Hyperboost driver @ 2000ma

Wow! Just Wow! Thanks for sharing!

+1 :wink: :beer:

Looks like I will be doing an emitter swap on my 9xT6. I ever so boldly dedomed ALL 9 :weary: Killed one being lazy doing it without heat but that was the best thing that happened lol.

Put it back together, doesnt seem to throw much farther if at all and now is majorly ringy :Sp
Bummer. Well $60 later it should be nice neutral beautiful XM-L2 goodness!

If It has been stated already I missed it, what are you using for a driver?

Im using a hyperboost driver from Taskled.com. I considered dedoming mine, I think I will leave well enough alone.

You should be able to turn up the juice with 9 emitters. Im stuck at 2000ma because of only 4 batteries. If you are using 4 lithium ion batteries you should be able to push 2.3A to the emitters with the hyperboost driver. George does not recomend going over 6A input current from the batteries with the hyperboost.

I got an additional extension tube for 5 batteries. I havent tried it yet.

sounds like a real beast!

The HB flex has different modes too.

I like the all or nothing on my hotrod lights though. :slight_smile:

wow, you ran it for 3 mins and it only got warm! that is waaaaay impressive. did someone say you are getting about 10,000 lumens? or was he just exaggerating?

my 9xml ak47 is doing about 6000 lumens, and it gets warm within seconds. the longest i ran it on high was for about 45 seconds, and it was very warm/hot.

the ak90 must have better heatsinking then

edit. actually just ran the light. it starts getting slightly warm at 20 secs. i ran it for a minute now, and the head is warm, not hot yet. but no way i would dare to run it for 3 mins.

It probably was not exactly 3 minutes, Im just guesstimating. It was every bit of 2 minutes though. I will do some heat tests the weekend.

I used thermal compund on all the threads of the head the get use of the fins to disapate the heat.

Someone elses hot, may be anothers warm too. :slight_smile:

Ken

thats true, but still, you have one bad ass mofo light .10, 000 lumens at that size and can be ran for a few minutes is super!
your medium mode is prolly my high mode on mine, and you can prolly run it on that mode for over 10 mins .

Man, the more I think about what you've done, the more I'm thinking of doing soemthing similar to the J18 - taskled hyperboost driver, 7 XM-L2 U2's on copper, etc. It would be a mini version of yours but thinking I could exceed 6,000 lumens with it for sure, maybe hit 7,000, a whole lot cheaper - $45 host (WallBuys), ~$45 driver, about $35 in LED/stars using IOS's XM-L2 U2 1A or 1C's on Noctigons (at qty 10, they are $5 each!). Think that's about half your cost. The taskled driver seems vastly superior to anything else out there - just don't understand it all yet - not much info.

I have to say, for only doing this flashlight/laser stuff since about March, I have learned a lot!

My AK-90 does not have modes. Its all or nothing. The HBflex driver that Taskled has, does have modes. I will put the HB flex in my shorty 12 XML light when I get it from Kaidomain. :slight_smile:

Ken

Do it! You could probably turn the current up even more with “only 7” leds. Hehe!

The formula that taskled has on his site is what I have been using. The formula uses lowest voltage of your batteries so your very safe. :slight_smile:

Ken

And now you want to add another 4000mAh to this light? If you make it any bigger you’re also going to need a surplus MG42 tripod to mount this thing on. :stuck_out_tongue:

Haha! This is definitely be a strap light.

Do you have a Trustfire X6? That comes with a sling. Or perhaps go tactical with a Magpul single-point or some other such nonsense :bigsmile:

thats what im talking about, while your at it, make me one as well! LOL.
but wait a second, its not just about hitting that mark, but once your there, i dont think the j18 can handle all that heat right? itll just be like my 9xml ak47 @6000 lumens where your only able to use it for about a minute or two max each time.
for the j18, itll probably be worst.

why dont we do it real big, and get the 15xml and try and hit 12, 000 lumens!? LOL
i found it for $85 shipped.
you down!? LOL

Been considering the heat mgt - easiest thing may be a big custom heat sink plug for the top of the pill, but some logistics issues there - can't get it in because of the smaller opening. Hhhmm - maybe replace the pill top with a big copper heat sink, or, cut the head off through the pill, add an insert, copper heat sink, and more massive alum cooling fins in the new section. This would increase overall length the pill area/flashlight size. Sounds like a project for MrsDNF, not me for sure...

The HBFlex driver sounds like the best -powerful mode setup, up to 3A per LED. I think 6,000-6,200 lumens total would be about the max. Hard to imagine getting 900 per LED at 3A, but not sure.

I reckon you’d have to do me a plan in the dirt with a stick for this mod. :stuck_out_tongue:

thatll be awesome hahah
ill purchase it from you after its done
