3D Streamlight Updates?

I have an old 3 D cell Streamlight that I got back in Scouts probably about 20 years ago now. Outside is kinda worn now but it still works fine but it seems rather dim compared to all my shiny new tactical lights.

Is there anything I can do to update it a bit? I know there are a bunch of Mag conversions, drop in LED's etc out there but I wasn't sure if any of that would work with a Streamlight body and lamp assembly.

You have a SL-3DX which has a bulb not a LA like the newer SL models. So you can do any coversion in that light that you can do in a 3D mag whether it be incan. or LED.
PS I used to have one too!

They stopped making these 20 years ago so i'm surprised this web page even exists.

Thanks John! That's what I was hoping to hear but I wasn't sure as I haven't seen much info on working with the Streamlights. Now that I hear they stopped making them that long ago I guess that explains it!

Gotta read up on Mag conversions now...

Sounds like a 3D version of my 5D Excalibre Halogen.

It uses PR based bulbs, and I have it running an 1111 on 6C NimH. It has a thin metal reflector and a plastic lense.... short runs only!

You should be able to sleeve the 3D for 4C, and if you use NimH C it should have decent semi-regulated runtime!

What's the serial number? It could either be a Kel-Lite II, an SL-3DX, or an Excalibre.

The basic design is very similar to an SL-20X, but without the charging board and with a metal bulb tower instead of the bare wires for a potted lamp. Probably would work with with a reasonably powerful bulb, as long as you don't melt the lens or the plastic insert in the bulb tower.

However, there's a big problem with modding these. Don't do _anything_ that could damage the light at all. Streamlight stopped supporting these years ago (so much for a lifetime warranty) and will only give you a few dollars off a cheap imported Twintask if your D-cell light breaks. If you melt something you're sunk unless you find an old servicing dealer with a parts stash. I'd personally go pretty tame in the modding department for that reason.

Maybe try a Luxeon PR dropin? EverLED, Diamond, Mag, etc. You'd have pretty good heat dissapation with the metal bulb tower that's coupled to the light's body. No danger there.

I'll have to dig it out of the garage and take a look. I'll repost once I grab it.

Try 4C NimH in a 1" PVC sleeve against a 3 cell M*g Whitestar Krypton bulb. That won't melt anything and should be a decent step up!

Okay, looks like the serial # is:

KA765797

So what's that tell us?

I wouldn't know what it tells...

My 5D Excalibre Halogen is KD113260

Does your's have <---SPOT/FLOOD---> around the head? on the other side mine says "Excalibre Halogen tm"

Tstetz's is probably a Kel-Lite II if it also has a CA locale on the tailcap. By the time they were calling them SL-3DX's I think the numbers had changed quite a bit. Same flashlight though.

That sounds right. It is CA on the tailcap and has nothing on the head.
