    Rolleye11 Introducing "PTS2"

    It has been almost a year since the introduction of the PTS (Perfect Tri-Sink). In the LED world this is like an eternity.

    I finally got time last December to do a complete overhaul of the PTS design to address the various issues that came up with the first revision.

    === Issues Commonly Brought Up ===
    1. Use the PTS with 3x Luxeon V.
    2. Hold the PTS down to the Mag bezel using screws.
    3. E-can for the electronic converter.
    4. Mag bezel height variation cause PTS to sit too high/low
    5. Too much compression force from the lens pressing down the reflector causing damage to the LED.

    Well, I heard all those concerns, and all of them were taking into consideration for the revision. So I took the work done on the PMS-K2 development and transfer the knowledge learns to the PTS2. I went all out with no expense spared in attempt to make a truly ”Perfect Tri-Sink”. So the following improvements were made.

    === Enhancements ===
    1. Increase in overall mass of the heat sink. Since I can’t change the width to depth ratio (standard in HS design), I tried to slap on as much material as possible to achieve the 2:1 ratio without compromising with the functionality.
    a) PTS2-C (2.2oz) vs PTS-C(1.5oz) … 47% increase in weight
    b) PTS2-D (1.7oz) vs PTS-D(0.7oz) … 143% increase in weight

    2. Increase the surface area to bring that heat to the Mag exterior for convection and conduction cooling.
    a) PTS2-C (7.170 sqin) vs PTS-C(3.969 sqin) … 81% increase in surface contact
    b) PTS2-D (6.804 sqin) vs PTS-D(2.058 sqin) … 231% increase in surface contact

    3. Provide an e-can for the electronics. E-Can size is based on hotlips/osink defacto standard.

    4. Provide three pin hole locations for locking screw tap.

    5. Threaded portion to screw down into the Mag head. This eliminates the necessity of tightening the lens retaining ring to compress the lens / reflector / LED. As an added bonus the threads will be able to compensate for the variation in the Mag bezel shoulder.
    IMHO this addition is the greatest improvement for usability.

    With the above enhancement I’m confident that this HS will be able to provide enough thermal transfer to the exterior surface so that we can now use 3x K2 or even 3x LuxV. The ball will now be thrown to the other side of the court, where the new problem is how do you get rid of all the heat buildup on the light exterior? Well the answer is quite simple how about some groovy head like what cmacclel have done. :wicked:

    So with all that said let me present to you the latest addition … PTS2









    === Recommended Host / Batteries / Driver / LED combination ===
    Mag2C / 2x18500 | C-LiIon / Fatman or Shark / 3xLuxIII
    Mag3C / 3x18500 | C-LiIon / Shark / 3xLuxV
    Mag1D / 4xAA / Fatman or Shark / 3xLuxIII
    Mag1D / 4x14500 / nFlex / 3xLuxIII
    Mag2D / 2xD-LiIon / Fatman or Shark / 3xLuxIII
    Mag2D / 2xD-LiIon / Shark / 3xLuxIII
    Mag2D / 8x14500 / Shark / 3xLuxV
    Mag2D / 6|7xAA / Fatman or Shark / 3xLuxIII
    Mag2D / 6|7xAA / Fatman or Shark / 3xLuxIII

    * Listed in order of performance per size and level of difficulty
    * Note LuxIII is interchangeable with K2 (when available as stars format)

    === Recognition ===
    Special thanks Icarus for the design review and recommendation on the threaded enhancement.

    This looks gery good. A nice evolutionary step forward. Nice, I would certainly be interested in in having a coupple of these to build a light on.

    Ooo Re: Introducing "PTS2"

    When? Where? How much?

    Now I'll have to go to the basement and try to find the parts of that Mag switch that dropped beneath the bench when I disassembled that old Maglite...

    Merci mon frère for all the supportive comments.

    Both of these units are currently ready for shipping.
    The problem is I don't know how to price them. Should I price them by $$$/oz, $$$/Surface Area, or $$$/R&D time & effort. Just kidding! If I do that you guys are gonna

    So how about $15/unit. I hope it won't make anyone since it'll be less than 20% of the upgrade cost.

    I'll conduct a limited (small quantity/ 2 weeks time) introductory sales in hoping to see some new 500+ lumens finned Luxeons lights modding. (Sales Thread)

    Due to my current work load I won't be able to handle all the order fullfillment like the last PTS/PQS run. So after this intro-sales, I'll probably ask the Sandwich Shop to help by carrying all these in their inventory.

    What do you guys think?

    I'm all for letting the Sandwich shoppe taking all the orders.

    Will you making a new model of the PQS as well?

    Beautiful work but how do we get 166 lumen LEDs?

    Billson: I'm waiting to get couple K2 before I finalize the design for PQS2. I want to make it so it's "universal" to save the setup cost.

    Mike Painter: W-bin LuxV lumen ranges from 147.7 - 192.0 (average = 169.85). They can be found at The Sandwich Shop or by forum member PhotonFanatic

    modamag,

    you set up the PTS2 for so20 reflectors. Nothing wrong with that, but I can't find the dimensions of these reflectors - and I'd like to use the 20 mm carclo optics (bigger choice in beam setup). So can you (or anyone else for that matter) answer me one of those questions:
    - how high are the IMS 20mm reflectors?
    - does the PTS2 work with 20mm Carclo optics with the hex holders?

    Bye

    Hi Markus,

    The PTS2 will not work for optic.

    I did however make an optic version PTS-D-TypeO which might work for you. It's significantly higher to accomodate for the optic height (or lack of).

    Here are some info on various optics hope they help.

    IMS SO20XA


    Carclo 20mm optic


    NX05 optic


    Fraen optic

    By screwing into the head, I take it that the head doesn't screw down all the way on the body then? But by screwing on the HS into the head first this elminates the possibility of screwing the head onto the body and the body pushing up on the HS correct?

    Reflectors don't get as much pressure on them from the lens either then right? If my leds weren't epoxied to my exsisting pts, I'd upgrade as my reflectors are sort of "oval" now from the pressure!!

    IsaacHayes: You first screw in the PTS2 into the head. Then the head to the body. The distance difference is 0.200" so it will barely make any difference on the light length. An as far as pressure on the reflector you can put as minimal amt as you want. That pressure is only used to prevent rattling.

    Ledean: The next project is nothing related to flashlight. I want to build my own little monsterbot from scratch. Have to put those mill/lathe to work for something useful

    Jonathan,

    In that case, I may just wait for the PQS. When will the shoppe start selling your heatsinks?

    Can we substitute the McR20 for the IMS20. I'm not sure if there are differences in depth but I'm assuming they're at least the same size because they are both 20mm?

    I think the McR will fit, at least I think I've seen someone use those with the old PTS/PQS...

    I've seen some people use it but they didn't say if it the light had to be modified in any way.

    Hi modamag,

    thanks a lot for the drawings, they did indeed help. From what I can see, there's nothing wrong that a bit of epoxy won't cure :-)

    As I understand it, the only problem whith the optics (assuming hexagonal holders - the round holders are half a mm larger in dia. than the SO20s) would be that there is too much distance between the front glass and the optics so that the glass can't be used to hold down the optics?

    In this case, the obligatory glow-powder/epoxy mix down inside the head can also hold down the optics (or at least the holders). I know that in this case I won't be able to exchange the LEDs if one of them goes bad (or better ones come out), but usually (i.e. so far) I seal my LED heads anyway.

    See you at the sales thread - I'll just have to decide now how many PTS2s I'm going to need for one Maglite ;-)

    Bye

    just a suggestion, but why not machine some "fins" in the rear instead of a solid mass? or even in the front where the luxes are? this would reduce the weight and increase the surface area. it may increase the cooling capacity despite being in a sealed envioronment.

    I think the idea was to increase the mass so it would be take longer to heat up from the LED's and to increase the surface area in contact with the Mag body/head to better transfer heat to the outer surfaces where it could be dissipated.

    Oh, man.

    You really need to build Perfect Quad Sink 2 for the K2.

    That way you get even more of my cash!!!
