Scorpion rechargeable?

[Chop]

Does anyone out there own both a Scorpion and one of the Stingers. I was on Streamlight's website and noticed that the Stinger bulbs are 3.7 volt, while the Scorpion bulbs are 6 volt; although both are bi pin designs.

I was wondering if the Stinger bulb would fit (or could be made to work) in a Scorpion. If it would, it seems like the Scorpion would be a good candidate for a Pila rechargeable battery with the use of a Stinger bulb.

Feedback, please.

Don't have either but if they're both bi-pins with similar dimensions, I think you got yourself a rechargeable. 3.7V is just about right for a Li-Ion cell. Do you have either light? Sounds like a cost effective, no-brainer mod.

Chop,

Great idea. Let us know how it works out.

I do have a scorpion, but no stinger. Guess I'll just go to the local police supply store and look at/get a stinger bulb and see. If I need to open the reflector up a little on the Scorpion, I'll probaly try it. I mean, it's just a $20 flashlight. I has, however, served me well.

I have both at work.
I'll check tomorrow.

GJW,
Thanks alot. I'll check back tomorrow.

Here's the scoop:
--Stinger bulb fits and works in a Scorpion. I even used the Scorp's two 3V cells on the Stinger bulb and it didn't blow. A VERY white light. Who knows what the lamp life would be, though, putting 6V through a 3.6V rated lamp.
--Scorp bulb works in a Stinger, though is a bit dim. May work great in my 6V Stinger...But the O-ring around the Stinger's bezel fits pretty snug around the slightly fatter Scorpion bulb.
--Superstinger bulb works in a Scorp, too, but is dim.

The stinger lamp is pretty high wattage( IIRC 5-7 watts), the result is a very large load on the scorpion batteries, so odds are
the applied voltage is probably more on the order of 4.5 volts due losses within the battery, otherwise the life expectancy of the lamp
would probably be on the order of 30 seconds, at 5 volts it is probably measured in tens of minutes, so at the nominal 3.6 volts, the lamp is about 2 oms. At higher temperatures, the resistance goes up.


For example the Surefire M6 uses 6 Lithium cells, when loaded with the 500 lumen lamps (about 30 watts), you are only getting
about 2.4 volts per CR123, i.e. a load of 1.5 amps will drop the voltage on a CR123 about 1 volt,
and my gut feel is you are running about 2 amps through the lamp with the two CR123, which is going to drop the voltage to something on the order of 4.5 volts.

That is the only reason the lamp survives more than few seconds.

Chop,

Are you gonna try the Pila's on the Stinger bulb? (Do you even have Pila's?) The bi-pi design of the 3.7V lamps opens a set of possibilities for mods on other lights as well /ubbthreads/images/graemlins/grin.gif

Scorpion on the left -- Stinger on the right.

Looks like the Stinger bulb might be uncomfortably close to the Scorpion's Lexan lens unless the greater length needs more CC defocusing.

[GJW]

Yep, with mine screwed all the way down, the Stinger bulb is practically touching the Scorpion lens.
Can't really tell about the focusing because I'm trying it while off.

GJW,
Thanks alot. I suspected that I would have to use some type of spacer between the LA and the head to drop the LA a little in the head. I had to do this when I modded my E2e to a accept a P91 to get a good beam. This should effectively put a little distance between the lamp and to lens too. I think I'm gonna try it.

Thanks again.

OK, I did it. I put a Stinger bulb in my Scorpion and used a single Pila 3.7v batt to drive it. IT WORKS GREAT.

Now for some runtime tests.

By the way, has anyone tried a SuperStinger bulb in a Scorpion and run it with 2x123s or 2 Pila 150S's?

Here's a beam shot of the Scorpion with the Stinger bulb. On the left is an A2 and on the right is the Scorpion. The Scorpion's beam is focused to provide the tightest beam I could get.

As you can see, the beam of the Scorpion isn't as white as the A2, but it is also not costing me anything. It's pretty bright too.

In case you're wondering, the Scorpion beam looks the same with the stock bulb too. It just seems to be the temperature of the Streamlight bulbs.

The Stinger bulb doesn't come close to hitting the lens either.

MORE GUILT FREE LUMENS.

I do love my A2 though, with its always white, always bright light.

CM,
I have a P91 Mod, not a P61 Mod. I used the A2 instead of the P91 because it just wouldn't have been fair.

 

[CM]

How bright, compared to something we're familiar with, maybe the P61 E2e you got. Beam shots ? /ubbthreads/images/graemlins/grin.gif This sounds like a great rechargeable conversion mod.

Very cool !! Good thinking !! I may actually have to buy a Scorpion now and plunk one of my Li-Ion cells in it. I would like to see how the runtime tests turn out.

I was trying this just to see if it would work. I'm in the process of adapting the Streamlight bulb holder to my E2e. I know that the Scorpion isn't very big, but it still isn't as pocketable as my E2e. The Scorpion bulb holder is about the same diameter as the E2e bulb holder. It's just too thick. I'm working on taking off material by hand. Going slow. I don't have a lathe, yet.

Chop,

I tried a Strion bulb in a Scorpion and it works well. It's possible that the Strion bulb will work better than the Stinger bulb, because it is designed for LiIion.

Once that worked, of course, my immediate next step was: how do I get one of these lamps in an E2e /ubbthreads/images/graemlins/smile.gif If you can make an adaptor work, I'm all over it!

I tried a less general approach. Rather than a reusable adaptor, I gutted an E2e lamp, by drilling out the bulb and potting material (crunch, crunch). It came out fairly cleanly. The Strion lamp fits loosely in the MN lamp base, but if carefully centered/potted it should be fine. Now to solder the leads.

This is where I got stuck. I can't get solder to bond with the metal parts of the lamp base. Any suggestions?

The adapter he made is in the mail to me I think.
