[wolfy]

Im ready to buy a chrome kit!!

Hey Guys I have the final Chrome parts in hand!!
The look even better in person.

While I think I get the jist of this thread...am I right in thinking that you would need to have some Arc parts lying around (innards) in order to take advantage of these hosts?

If there is ever a working version of these complete and available, I'd like to call 'next in line,' for whatever that's worth.

In any case, these look 100x better than any other Arc host I have seen on these busy forums.

If the proper LE is fabricated, no additional parts would be needed. But if you plan to do something more like stock, yes. The only parts that were in the original are, the optic/board/retaining ring & o-rings I believe.

My popcorn is already stale, and I have a sneaking suspicion this is not gonna happen.

My popcorn is already stale, and I have a sneaking suspicion this is not gonna happen.

I sure hope it does... I just received a first run Arc LS from a poster on the marketplace... I'd like to get it updated, so I contacted milkyspit... Hopefully, between the interest expressed in this thread, and his previous experience modifying Arc LS's, he can whip up some magic.

As an aside, does anyone know where a new heatsink can be found? If Scott doesn't reply back, I think i'd like to try my hand at modifying one of these myself, even if it just ends up being an emitter swap.

You might want to see if you can crack the head open before you make too many plans, I have had a couple that were impossible. As far as new heatsinks go, they are hard to come by. I think something would need to be manufactured if these are going to be hot rods. I have these two on the right that were with my Arc stuff, not sure what they are exactly.

Getting closer to having everything needed...

[John_Galt]

Getting closer to having everything needed...

So, other than contacting Scott, does anyone have any ideas for a driver? The driver in the original Arc LS's was mounted on both sides of the heatsink... Not much room to do much else, unless we're going with something along the line of a new heatsink/driver-emitter/optic package such as... Oh, who's it that has the XP-E/G triples and singles with the driver components on the PCB?

first off ... apologies to OP for this possible hi-jack

all of the above has been covered eons ago when highest performance emitter was considered an Xbin Luxeon.
if someone wants to start a new thread on this topic ... will be glad to jump in. please PM me if it happens.

[karlthev]

Sure Charles, chime in! Good to hear from you!

You are correct, it was covered eons ago. But not sure we need to start a new thread, we still need to find out where the LE for this project is coming from. So I see nothing wrong with discussing it within this thread, as long as James is okay with it.

yup it's good to be posting on CPF again ... but generally it's not polite to garbage someone else's sales feeler thread. flashlight burnout can be deep ...

if I can find it, still got somewhere a copper heatsink Larry sent me. it'd almost be easier to draw one up with solid works. then have it CNC.

duuuuupppp

[John_Galt]

Hey CY, sent you a PM.

This is not a feeler thread, it is a thread in which we are trying to make these hosts complete. As you can see from the below quote, James is looking for some help in making this happen...So, please post any thoughts or suggestions you might have here.

Today I pulled the parts. There are going to be 15 sets that will include the main ORIGNAL. Arc head and cr123a twisty.
A cr2 twisty

The yaesumofo clicky.


I have copper heatsinks for them as well .
The jury is still out on the copper parts.

In any event they look as cool today as they did 5 years or so ago.

A cool improvement would be to have ORIGNAL clickie tails too. I did not have any of those when the chrome plating work was done. Oh well.
The mofo tail is a great replacement
I'll send a set to milkyspit. Let's see what he comes up with.
Anybody have any interesting ideas?
Let's hear 'em.

Perhaps member spc would like to get involved

Or perhaps vinhguyen54?

Looks like a few threaded ARC rings are still available at the Sandwich Shoppe.

Aleph LEs will work in the 2nd generation ARC heads like these, this gives you some options in readily available parts and drivers for a DIY solution. An Aleph LE is thicker than the original ARC electronics/heatsink, so there will be an issue with space on the "length" or "z" axis that will mean a cut down reflector, custom reflector, or no reflector would need to be used. I once milled as much as possible off the bottom (while still leaving just enough to contain the driver board) of an xr-can to get about 1/8" back when making up an LE for an ARC...That helped make space for most of a McR 18 in the head.

Fortunately the ARC LS has a bit of "adjustable length" available in the head-battery pack joint. So long as the o-ring is covered and the head does not bottom out on the battery pack before making contact between the LE and the battery, it's all good.

[wolfy]

I would be happy just to buy the shell and add my own electronics.

I was thinking for something usefull, perhaps a neutral XP-G and a GDuP 1.2A driver.

thanks for the clarification ... just now noticed date of this thread is from 2007 ... me thinks original offer is all but dead.

it's been quite sometime since I've been active on CPF... so forgive me if I'm not up to date on what the latest boards and emitters are.

long ago... when the original ARC company went out of business. several large blocks of parts got scattered to the wind before I managed to buy the entire remaining inventory of ARC from Peter. then I proceeded to chase down every batch of parts possible that I didn't buy from Peter.

pretty safe to say, I've still got the world largest cache of ARC parts.
one cannot change ARC's place in history as world first production Luxeon light.

ARC's timeless design will never go out of date. but electronics and emitters have long since gone by the wayside. good thing ARC LS (not first run) were designed from the get go to be modded.

note ARC LS first run were potted in epoxy, opening would generally destroy guts and sometimes body. so please don't destroy the few remaining working ARC LS first run lights. most folks are not aware first run electronic were one of the most efficient at draining a CR123 cell ever made. take a dead CR123 cell out of other flashlights. odds are that battery will still work in First Run.

I've still got available most of the parts listed in my signature link. look through the list, then PM to inquire if still available.

All we need to complete the project is an LE, reflector & window I believe.

that's assuming the original chrome ARC bodies are still available posted from 2007.

I've got a few sterile bodies with un-anodized twisty tailcaps and/or HA clickies tailcaps that could be chrome plated if anyone wants to take up this project.

should be able to find the proto copper heatsink Larry made awhile back. but that model probably will not be correct for current boards/emitters

please post currently available desirable electronics. preferably an entire light engine like the old sandwich or sammies from Dat2zip. P60 dropin modules are another standard light engine. that's too big of course.

anyways... to update me, please post all the super coool current options for emitters and boards.

[F250XLT]

Cy, you may want to read through this thread. James revived it, stating he has around 15 hard chromed sets available. We are currently trying to come up with a modernized LE for the stock hosts.

[F250XLT]

Alrighty then, I guess this one is gonna go by the wayside once again. No more bumps from me, wake me when something happens and perhaps I'll still be interested.

[yaesumofo]

Cy and Group.
This is not all BUT DEAD.
Milkspit is working up a build.
I have the chrome parts.

I have build one up myself with my copper sink and a flupic driver emitter board. (I have a few of these around somewhere!!! I have yet to find the bulk of them....
It works but is not very bright compared to some of today's lights. So I know there is potential with this combination.

What I will do especially if there is desire. is to sell the existing chrome sets to those of you who want to build up your own solutions.

I have sent scott a set for a build up. as a courtesy to milkspit I will wait for him to post his solution.
then the sets will be put up for sale..
Lets hope he is done soon.

I have great hope for these lights. just a little work is required to figure this one out.
Remember those Arc mods that used a Penny as the heat sink??

More really soon I hope.

We may all grow old before this happens I'm afraid...
