    Default super simple luxeon headlamp/li-on combo (afordable) Streamlight Argo HP

    super simple luxeon headlamp/li-on combo (afordable)

    take a Streamlight Argo HP, 2x CR123 headlamp (aprox. $25) then add one 17670 or 168s li-ion cell. that's it...

    guilt free lumens and eliminate reverse charge danger by going to a single li-ion cell.

    this has got to be the smallest headlamp with this much mah capacity. Argo HP is not as durable as Stenlight, but stands on it's own merits with li-ion cell.

    note: to avoid overtighen cap problem with Argo HP. remember to unscrew 1/16 turn after seating cap. since both batt caps look indentical, to avoid killing you hands trying to remove wrong end. mark the cap that actually comes off.

    heh, nice find there CY,

    Is the output any less?

    I have the 3xAAA version though
    Love how small it is, but its just about useless due to the SHORT runtime.

    Actually ordered one earlier tonight(amazon $33 no tax free ship), figured since I would have 17670s around for another upcoming bright light :P

    Seems to be the only li-ion rechargeable headlamp around for the price.

    btw how much is the output reduced from 2x123?

    output is almost the same w/17670. with 2x fresh surefire cells. it's barely brighter.

    runtime should improve too, but I'm not a runtime guy. not enough patience

    this setup makes an impressive backup light to stenlight. or primary for times you don't need a full blown setup like stenlight.

    I've been using Argo HP/17670 along with ti PD for wrenching/worklight duties.

    can anyone confirm that you can change the side emitting emitter to a normal luxeon? I've heard it makes a beam without the artifacts...

    cy,

    let us know if its possible to gain access to the LED... i heard it can be done but never got any pics or anything confirming it...

    A 17670 SXOH headlamp is quite the package

    have not swapped luxeon yet, but it looks super simple. mine has a one watt side emitter luxeon star.

    there's two small phillips screws holding down a plastic cover. unsolder two wires and that's it...

    ok.. just finish Sbin star swap.

    need to retract my statement about this being easy. the soldering is easy, but when you take Argo HP apart. there is quite the mod potential inside. IC is not marked and I have not measured current yet to determind what type board we have.

    after swap, output almost doubled. it came with a PWOJ. I switched to a SX1J to maintain same vf.

    Argo HP is difinately a well put together unit. star sits on an aluminum heatsink that has some type of heat compound. seems both low and high beam is regulated.

    beam generated quite the donut hole. tightened bezel and improved somewhat, but cannot get rid of donut. reflector could be sanded down to focus beam.

    edit: sanded down reflector support to allow reflector to sit deeper. beam improved. need to sand down more... donut is almost gone.

    throw hugely improves along with output.

    thanks CY!... its on an aluminum sink huh? Thats cool... If i remember both settings are regulated... however... the sample I messed with had the low setting too bright (like all headlamps)...

    why did you use the same vf?

    thanks for the update!

    aluminum heatsink is thin at best, but beats no heatsink at all.

    since IC is not marked and I have not taken time to properly take current/voltage readings under load. used same vf star to insure star is being driven at same levels.

    Argo HP is totally plastic light with a tiny heatsink and I would like to keep this light reliable.

    board inside looks to be robustly made and looks to have loads of mod potential.

    Is the SX1J Lux I or Lux III?

    Just got mine yesterday and am impressed! artifacts aren't as bad as anticipated and tint is great. If the more experienced than me figure out what is the best star to put in is, I might try it. How would a U**J luxIII react?? Great headlamp, only issue is see is it's slightly front-heavy, but just wearing it a little higher on the head helps. Surprised it's not more popular.

    SX1J is a one watt star. have no clue how UWOJ would do. but results should be simular.

    have not measured actual current to luxeon, but it's pretty low. contained in a plastic housing with little heatsinking. would not want to drive much harder.

    this mod has gone further than planned already

    took it back apart and dinked with the reflector focus. emitter needs to come forward aprox. .090in. ended up with a nice spot pattern. donut hole disapears after 30in. this headlamp really throws! spill is reduced, so if you like spill. you may not want to change out side-emitter.

    this started out a low $$ mod, but Sbin nearly doubled budget
    there's is absolutely nothing wrong with original side-emitter.

    $25 Argo HP
    $8 17670
    $20 Sbin star

    here's a beamshot. note how tight spot is

    dangg............... that looks nice.... very impressed! Now you have a two stage, regulated, li-ion, S-bin headlamp!

    you've put me to shame! where did you get a $25 Argo HP? Thanks!

    EDIT: I'd be very interested in a runtime graph if you have the resources/time to do one.. thanks!

    actually Argo HP was sent to me for free from Streamlight at Shotshow.

    thought I saw a price online for $25, but could be wrong.
    not a runtime guy, so if you want a runtime. got to do this mod your self.

    i think, if we are gonna use a 18650, lets find out if the driver can support luxeon I with lower Vf?

    then we will have more fun
    if killing was legal, i would have killed countless number of people...

    have not tried it but see no reason why it would not work. but note Jvf in 3watt will be equal to Kvf in one watt.

    difference from one watt to 3watt is how they are rated. 700 vs 350 milliamps. it's hard to tell difference looking at emitter.

    from don's informal runs in his integrated sphere, three watt Ubin is slightly more efficient vs Sbin one watt. but that's based upon a small sample and final result will be determind by luxeon lottery.

    I'd try a Sbin Hvf, but really don't want to take back apart. it's a real pita tuning the reflector.

    headlamp is working really nice and puts out a fairly bright beam for the low current that Argo HP is drawing.

    be careful not to loose the tiny screws and take careful note how wires are routed if you decide to swap emitter.

    Please post back in this thread with photo's after you do this mod...

    I opened mine and found out that it using a microcontroller from Sino Wealth, SH69P46M.
    I also noticed that the switch PCB was marked HLX-1512L-1, so it most likely comes from the same factory as the Favourlight and Nuwai.

    Time to order some stars for modification...
    Thanks for the inspiration CY!

    thanks for the sharpe eyes... this chip has support for LVR, but don't know if it's enabled. Low voltage reset could mean Argo HP supports li-ion.

    Was the star glued to the sink or did it just contain termal grease? Mine was glued on, so the print on the backside of the star was in the glue, and therefore very smudged, when I separated the lux from the heat sink (the glue remained on the heatsink only), so I was not able to see what bin it was.

    mine was glued, but came right apart. could read the bin code, only backwards. print had transfered to glue.

    be nice if heatsink was a little thicker... but hey beats no heatsink at all.

    you can easily measure vf, then eyeball to get close to bin. mine was PWOJ, tint was nice and white.

    Cy,
    Nice mod and pictures. I've been eyeballing these ever since you pointed them out awhile back and they look great. I see where you say the stock side emitter doesn't have all that bad of a beam. I'm not into throw that much with a headlamp and prefer a nice spill beam. Is the stock SE good enough for dark area chores and walking?

    If the stock beam has artifacts, maybe a layer of the diffused WriteRight over the lens would clean it up. I put WriteRight over the lens on my RR headlamp and it improved the beam considerably.

    just sputtered the reflector on mine and it turned out fine. may have reduced throw a little, but worth it. writeright would be more floody, but reversible

    The stock light is not perfectly focused either, when I removed the bezel and was moving the reflector I was able to achieve a thighter focus. However, the beam was nicest when it was a little bit defocused. I like a wide beam on headlamps so I may try to use a McR18 or McR16 instead of the stock reflector.
    Btw, is is possible to sand a Lux as you can do with 5mm LEDs.
