Looking for a host for a pocket rocket XHP70 build

This might be in the wrong section and if it is admins please move to correct place.

Anyway, I’m looking for a host similar in size to a C8 to build a pocket rocket XHP70. I know heat will be a factor but I also understand when it gets to hold to hold then throttle it down, there will be lower modes for a reason lol. Size wise no bigger head diameter than 45mm and length no longer than 150mm. Prefer it to be a 1x18650 size light with an optional extension so I can run it on 2x18350s or 2x18650s. I would like to use the Qlite 6V+ zener mod driver from mountain electronics with the guppydrv firmware and running at 5.83A as that is the driver I have in my XHP50 P60 (but at 3A) and really like it.

I am new to modding so the available hosts and where is best to purchase them is a new world to me. So far I have only been looking at Mountain Electronics and while I have found everything else on there I will need I have not found the perfect host. I like the looks of the Shadow jm30/35 but the head diameter is too large. The Convoy L4 looks like a good candidate but I am not sure what driver it takes or if it is offered as a host. The light will be used as a short burst flood light for times when I need a high power light but for whatever reason cannot carry a larger light. As funds for toys are short due to family and college it might be a while before I get started on this but I wanted to get started on a parts list so that maybe I can order a few here and there.

Any help would be great as this is my first mod/build, RMM built my XHP50 P60 which I love. I do have knowledge of electricity but when it comes to the chips and driver components I am mostly lost so I will be looking to buy a prebuilt driver to begin with.

Thanks,
Tac

There should be lots of options for those available. (some other members will have more experience in C8 sized muti-cell hosts than i have. being a higher voltage XHP70 mod as you mentioned you would be better to go with either a two-18350 cell or two 18650 cell set up to drive the higher voltage driver needed to run the XHP emitter. The popular Zener-diode modded Nanjq Q-Lite 105C to drive 6-volt emitters is my favorite driver. The two 18650 would be more ideal for for higher currents and run times, but will make the host twice as long.
i have built a few other XHP / MT-G2 lights but mostly in bigger hosts.

I have a Convoy L5 ,MT-G2,DDFET 5Mode. With ext. tube. But I like running (2) 18350’s in it with the sleeve naturally. I like that I can run (2) 18650’s or (2) 26650’s also. Makes it pretty versatile and stealthy little light, for a Jacket Pocket Rocket! It would be the smallest I would go. I put MT-G2’s and XHP-70’s in smaller lights like the S2, but the WOW factor wore off pretty quickly! Those little reflectors don’t let the big emitter’s stretch their legs! And of course the insane amount of heat, makes it kinda of useless to ME! Plus the L5 has a pill and really good heat sinking, IF you soldered the board directly to the pill, soldered up the threads of the pill lightly, leaving the first couple threads clear, to help re-thread it into the head, and it tightened it up for better contact. No more pitch slop! Then opened up the reflector too, to fit around the emitter base, just enough to self center the reflector. The MT-G2 on a DDFET puts out a great amount of light, and you just can’t beat the tint or the beam! No doughnut hole! Just my 2cent’s! :wink:

I like the looks of the L5, a little bigger than what I am looking for diameter wise but would still work and I like the varied battery compatibility. Does it have a side switch as well or just a tail cap switch? An mt-g2 would be plenty on a DDFET or even regulated, you wouldn’t be able to tell the potential 1000 lumen difference between it and an XHP70 anyway, and no donut hole.

I like the way your thinking.

you said “The light will be used as a short burst flood light”

well most folks will say that the MT-G2 is a more floody emitter.

I have found the TK35 clone(s) to be an excellent floody host for MT-G2 lights. They are built 2x18650 in series so it is really just an emitter swap and boy are they floody and tough uses a C8 sized reflector and lens so you have lens options (the reflector is built with its own “pill” so it is a keeper. If it is not floody enough you can also add DC-Fix and run fancy IMR cells.

search for TK35 clone BLF TK-35 clone and there are threads with how to mod and a list of all the part numbers they are sold under, if you go direct drive (like I do to keep it simple) then you can also try other battery configurations (it is really hard to kill an MT-G2 using batteries.)

I also recently found a SAIK SA-305 recently, (OL’s first of three parts, video just to bring back memories) https://www.youtube.com/watch?v=on-52LtDdtg

My recent idea (I have one coming) is to use three 14500 in series in the SAIK SA-305 to run an XHP70 for short blasts.

Push button. I think Convoy quit making the L5? But there are clones to be had. One has an OP reflector. Loading... https://www.fasttech.com/products/1601/10003006/1225302

I wondered if there were any tk35 clones, those wouldn’t be bad either

Look under the following “names”

Small Sun ZY-T92
New-117
117
Unique Fire UF-F10B
UniqueFire UF-F10
S020017
RD-777
W777
and some times “mislabeled” as Fenix TK35

Just read Johnny Mac’s review of the Unique Fire UF-F10 and I really like the looks of it. My only question is swapping the driver. I would really like to have a regulated driver with the guppydrv firmware but I have not seen a driver that size. Would I be able to unsolder everything off of the stock driver pcb and just use it as a mounting board for whatever driver I choose? Also what would be the max current the battery carrier could handle?

As long as you heat sink your piggy backed driver, with a FET driver no worries! Ld-2’s and 7135’s get HOT!

look at

OL’s TK-35 clone

link I think that is what he did.

Keep in mind part of the cool thing about this host is:

  1. you can use the stock driver for 6v emitters
  2. you can mod the stock driver for a low cost for 6v emitters
  3. you can strip the stock driver and run it DD for a very low cost (and also a fall back position) for 6v emitters
  4. you can add other drivers like OL did. for any emitter
  5. wight made a 6v driver PCB [WIP] 6v-LED TK35 clone driver thing: for TK35 and 'friends'

Another mini pocket rocket mod idea is the Mini DQG 26650 Converted to MT-G2.

Really like the looks of the TK35 clone build and I think I may go with it. Plenty of heat sink and I can work out the driver details once I have it in my hand. The Mini DGQ is neat and definitely a pocket rocket but I’d like a little bigger.

Ronin42 have you built this driver? Or de-bug it yet? Damn! How did I miss this? This looks like what I’ve been lusting for!! :bigsmile: [WIP] 6v-LED TK35 clone driver thing: for TK35 and 'friends' :~ I wish wight would come back! :~

Doesn’t have the best of heat sink capabilities but I like the looks of the Solarforce M3 head. Plenty of lego parts available and being it is a P60 plenty of options and easy enough for my first mod. May just use an mt-g2 at 3 or 4 amps for a better beam and less heat than an xhp70. I may try a K3 for the XHP70.

I did a TK35 clone to MT-G2, it’s heat sinking works but may need to add to extra copper where you can squeeze it in like between the reflector and head. It is a great set up and I still use mine on a weekly basis. However because of all the legos for the P60 that would be my 1st choice. FIVEMEGA on cpf sells a few finned heads and a couple milled from copper for the P60. With P60 you get 2-18350’s, 2-18500’s and 2-18650’s and McClicky switch. FIVEMEGA does make a 2-26650 host for the P60 but its to short to use anything but 65mm only 26650’s.
