Match's Mods: Streamlight Scorpion Mod - Will it Host?

Streamlight Scorpion + Hammer and drill = Perfect P60 Host

Gentlemen,

  Have you ever had a torch that you loved and cherished for years, only to wind up forgotten and neglected because some younger, prettier, and brighter torch came along?  May I present to you my first:  The Streamlight Scorpioin.

 

Our relationship started way back last century (1995 to be exact), and for more than a decade we laughed, we loved, were inseparable... But as so often happens I found myself not carrying a torch for a few years and soon my precious was demoted to "car duty" (shudder...).  It was only in the past 6 months that I rekindled my interest in all things shiny, and found myself buying new torches with these new fangled LED's... (and buying, and buying, and buying...).  Well, one night as I was rummaging through my old electronics bag I came across my old streamlight.  Compared to the new lights out there, the years haven't been kind to this old gal.  Popping a couple of fresh C123's in there, I was dismayed at the output after recently being spoiled by the newer tech. But still, there was just something about the size...the rubber grip texture...the perfect clicky...

  A quick google search of upgrades available turned out only a strion incan mod (blech....).  Out of nowhere the Six Million Dollar Man theme song started playing though my head.  We can rebuild her....faster, stronger, brighter!

  Not knowing the direction this would take I started with a simple teardown.  As it turns out, this is the hardest part of the mod.  After unscrewing the head and removing the bulb, the lens can be removed by pushing something blunt up through the hole.  The lens just snaps in place. Make sure the end is soft so it doesn't scratch the lens, we'll need that later.  The next part is pure brute force.  To remove the reflector, place the head face down on soft wood and find a suitable socket to use as a punch on the rear.  Apply ball peen hammer gratuitously to the makeshift punch and it should look something like this:

If one is so inclined, the clicky can also be accessed by using a very small screwdriver and carefully working it around the rubber sleeve while pulling.  Once apart it looks like this:

Once apart it was apparent that with a little work I could make it P60 host-able.  Aside from the tear down, the only thing I had to do was enlarge the interior of the head to accommodate a drop-in.  Turns out a 55/64" drill bit is almost the perfect size for this (7/8" will also work, but will be oversided and require more tinfoil or copper).  Yup, no lathe needed for this mod. Just drill down until the bit starts to touch the inner threads, then the depth will be perfect (just take your time to keep it centered).  It should look like this:

 And that's it for the hard stuff.  The rest of the mod is rather blasé, more like a P60 assembly.  As fate would have it, the day I started this mod a padded yellow envelope arrived on my doorstep.  Looks like 'ol bessy is getting an XM-L! The driver of this particular drop-in would only do 1.7A, so it was swapped with a SB 2.8A piece.  A single wrap of copper foil was cut and ready for final assembly.

The last part only requires snapping the plastic lens back in place.  Mine had been scratched to hell and back from over a decade of carry, so a new one is on order.

And that's it.  I've fallen in love all over again.  The neat thing about this is that a used scorpion can be had for @$20, which puts it in the same price range as a solarforce.  But the IMHO, there's no comparison...The scorpion is smaller, slimmer, has a better feel due to the full rubber grip, and doesn't have any pocket shredding "tacticool" assult crown.  The fact that's it's now putting out roughly 10x the lumens doesn't hurt either Tongue out.  Although it can be run off of primaries, I suggest using a good 17670 (depending on driver/emitter combo, of course). And that's it!

Here's some before and after shots Wink :

Nice one! I love the before and after lightning bug vs. A-bomb comparison! Frontpage'd and Sticky'd. Thanks for keeping us entertained with this.

 

 

Can I make a request for a future episode? This...

 

...is one of the few flashlights that I have tossed out. It's actually a very attractive host, but utterly worthless because of the 9 glow worms that consume 3 AAA batteries at a time. But I bet you could make a real pocket rocket out of this. It has enough diameter to fit a P60 I suspect...

Thanks for the nice comments.  sb56637, I think I know what lights you're talking about.  I've seen them at the dollar store.  Although I have reservations about it being a good host because the few I handled seemed like they were made out of heavy gauge tin foil.  Then again, it's only a buck....I'll pick one up and let you know.

Love it. Smile

I have a Surefire e2e that has served me well on three continents for well over a decade, in the desert, in sub zero conditions, more or less crudely attached to different helmets, dirt bikes, mountain bikes, firearms of various calibers, pets and Lord knows what else. It's not very bright (even keychain lights will give it a run for its money), it has been thorougly abused and it shows in places. And yes, it's still an incandescent light, just like the day it came out of the factory, a million and one bulb and battery changes ago. It doesn't get much regular use any more but I still absolutely love that light.

I've often thought about modding it but so far, I could never bring myself to do it. Smile

I'm not sure what I'd prefer....but what I have on hand is 6mil (.15mm).  The stuff I use comes off of high voltage shielded cable.  There's always about 6"-8" of the stuff that gets thrown out after the electricians at work get done making  a splice.

Hey Match, Great Mod.  I've had my Scorpion ofr years and love it.  I really want to do this mod.  Can you list the parts you used.  I'm new to the subject and the prospect of all these different dropins and drivers is perplexing.  I think i can follow your directions and rebuild this thing as long as I have the right parts.

Welcome, wpnorton!  It's nice to hear someone getting something out of my projects.  If I remember correctly, the only parts you'll need are a drill bit (I think it was 55/64") and a little bit of aluminum or copper foil. Measure twice, drill once.  If you're careful in removing the stock lens it can be reused.  Other than that, once modded, a regular P60 drop-in will slide in like it was made to.  The only other thing to keep in mind is that the drop-in I used I modded with a 2.8A SB driver.  The problem was the components on the backside making contact with the rim of the body if tightened down too hard.  Still worked great, just gotta remember to keep that gorilla strength in check. Let me know if you have any other questions and how it turns out for you.

Do you have links to the parts you used.  I can't seem to find anything on a 2,8v SB driver????? 

I think the below link is the lamp module your refering to?    Am I on the right track?

The drop-in I used was a 3-18v XM-L from kaidomain.com.  I used that one because I thought I'd still want to run it off of 2x16340's.  I didn't really like that drop-in as much as I thought I would, so I put a 2.8a 3 mode driver in from shiningbeam.com. I just looked and it appears that driver isn't listed on his site atm...which means he's out of stock.  This one is very similar.  If you look at the driver linked, you'll notice it has components on both sides of the pcb, which works, but is less than ideal due to the diameter of the body.  Honestly, if you want a great drop-in, I would recomend this one from solarforce-sales.com.  Combine that with one 17670 and you'll have a fantastic little torch. It's actually what I've since swapped mine over to.

awesome write up! I have a few scorpion lights that i didnt really know what to do with until now!

I am just learning, so I am just curious as to why you are recommending a XP-g drop in as apposed to a XM-L? I see some XM-L P60 dropins with 460 lumens, but again, when it comes to changing the driver, you lost me. I think i will have to get some in my hand first to see what everything is...

Would this work as well? http://www.batteryjunction.com/p60-dropin.html

Welcome Mustangous! (I like the name...I used to grudge race an '01 Bullitt.)

To answer your question, I don't think I recommended an xp-g, (I used an xm-l in the build).  Having said that though, I have since put an xp-g drop-in in place powered by a 17670 li-ion. (I still really like a good xp-g with a smooth reflector...)

Do you still plan on running yours on 2 primaries or single li-ion?  Deciding that would help narrow down your choices.

That's one (insert f-word here) great!

And on top of that, you brought that famous line. reminds me of that blender spots on youtube; "will it blend?"

I'll make use of that in the future! Wink

I been into mustangs since I was 16, now 32. Still have my original 90 fox. I need to get back into it though. Lol. House priorities. I plan on using 123's because I get them for free :-). I was thinking about the one I linked about with the 3 mode option. Was going to order through them, but hear their shipping takes 10 days. I'm a little impatient for that. Lol

You mean this one from batteryjunction? (your link just went to the general drop-in page).  That should work well.  It's not driven nearly as hard as some of the others, but since you're running on primaries that's a good thing.

Another couple options are a single mode and a 5 mode solarforce xp-g from Lighthound.  I've been using the 3 mode version, and it's the best xpg drop-in I've ever purchaced (this one doesn't like 2xCR123's though, but loves one 17670).

Took the scorpion apart today... The lens was a little tough, I used a wooden dowel. put a slight nipple in the lens. what did you use to get it out? Now i just ordered the XML, 3 mode and some copper strips off CPFmarketplace.. Hopefully everything works out!

Thanks again for the thread! Great help to make use of these scorpions i have. I have atleast 5 others that i am gonna experiment with other drop ins too... Laughing

I used the eraser end of a standard #2 pencil.  Good luck on the mod, let us know how it turns out for you.

Hmm... That's the first thing I though but my pencils are 5/16" and the bulb opening is 3/16. I hope we are working the same flashlight. Do you have the led or incandescent? They look the same from the pics.

Now that you mentioned it, I had to go back and check.  I found my origional reflector (I keep all extra pieces), and sure enough the pencil didn't fit.  I think I was remembering what I also thought to try first, not what actually worked.  My apologies, it's been awhile.  I honestly can't remember now what I used, may have been a chopstick.  

Heads up though on re-assembly... Once the drop-in is in place and you snap the lens back in place it's there for good, since there's now way to push it out.  I had to destroy my origional lens when I went to swap drop-ins.  Couple of choices here... You can purchase a stock replacement lens (what I did), or you can hollow out the center of the stock lens till it's just a thin ring and use it as a retaining ring for a standard P60 lens (what I'm going to do...) I'll let you know how it works.

Good point! Didnt think of getting the lens out after the new drop in is in. I'll have to make sure everything is good to go before I snap it back in. Where did you get the higher amperage driver from? Have to think if i want to do that before i snap the lens in, or just use a different light later in for experimenting. Where did you get a replacement lens from, streamlight? I am waiting for the dropin before I bore out the housing just in ass this one is slightly different. Now I just can't wait. I'm hooked! Lol

You can get a replacement lens here.

The driver I first used was a 2.8a 8x7135 unit from shiningbeam.com.

As mentioned earlier though, a minor problem with that driver is that the chips mounted on the underside get in the way when screwing down the head.  

Any of the above linked drop-ins should work fine though on 2xCR123.

I found this forum by google, it brought me to this post. Thanks Match. I too greatly enjoyed my scorpion. It was my first lithium powered flash light and it is what prompted me to buy a 6p. A few months ago my car got stolen, and in it was my scorpion. So I found a cheap one on ebay. It arrived with dead batteries, a melted lens and a dead bulb. But for $10 plus shipping, oh well. I decided I wanted to upgrade the bulb, preferably to an LED. However that seemed to be a dead end. Since I had upgraded my 6p with a cree dropin I decided to see if I could make my old p60 fit. It looked to be similar in size. So I found this post, and in a matter of minutes using a uni-bit I had my p60 in my scorpion. Now I just have to order another cree drop-in and a new lens! Thanks!

hmmm, there's a M@g 2xAA mod thread saying use a 25/32 bit to open up the head to fit the dropin.

Comparing that to 55/64 recommended here -- how come?  Do dropins vary that much?  (Wouldn't surprise me if they do).

Before I buy an expensive bit and start thinking about buying a little tabletop drill press ...

Hank,

  The difference is that in the mini mag thread I only used the pill, whereas here I used the whole drop-in (pill + reflector). The reflector adds a little bit to the overall diameter.

Pogue_Mahone,

  Welcome to the forums.  I'm glad you were able to get some use out of this old thread!  Good thinking on the uni-bit... they're handy little tools.  Did the stepped hole it make cause any issues?
