if it is a drop for the same surefire light as the one I used I cant think of a reason why it wouldn't work. not sure if they are better or not.

How many batteries does the cressi light use? If it is only two then the emitter will be fairly dim because of the low voltage; however, if it takes c-cells then you can make an adapter to convert it to cr123 lithium cells which will give you plenty of voltage.

Does this mod work on the non-LED version of the SL-6??
And why do the batteries have to go in backward anyway?

The polarization of the replacement emitter is the other way around, that's why.
BTW, my second attempt at this mod also failed. 1" ID is too small, I couldn't clamp them together in the (admittedly small) vise. I'll try a bigger vise or try to shave some al. off next.
And it doesn't seem to be any brighter than SL4 eLED. But if I can get it to work, it's a good mod for non eLED SL4, which is pretty cheap.

After grinding the emitter a bit I managed to clamp the whole thing together (phew!) And it works beautifully. It gets a bit warm and the head does not screw on fully but I think it'll be fine. It IS actually brighter than the SL4 eLED now that I had a chance to compare them side by side - I grabbed a cheap SL4 and modified that, leaving my eLED intact. I'm happy!
EDIT: Nope, I spoke too soon. It flooded and the emitter is now dead.. I give up. Nice mod in idea, but it's not working for me.

Cross posted from my local forum -
I purchased a Drop in module for a surefire light with a Cree Q5 in it. It came in the mail today, and I promptly tore it apart and stuffed it into my second hand Photon Torpedo. The same should work for anyone with a Scout, or UK SL4/SL6.
Here's the module I bought, (~$13)
The reflector threads onto the LED module, so it's actually somewhat focusable which is nice.
It's the same length as the original UK drop in that was in the PT, but it's quite a bit smaller in diameter.
So I took a piece of old Maglite I had laying around, and cut a ring out of it, then squished it and wrapped it with metal tape to get the right diameter. Make sure it's the same height as the old drop in's upper ring, or this won't work.
After that, flip the batteries in your light (the center post on the drop in is (+), opposite of the orignial) and screw the head on. Mine actually seats better with the drop in than it used to with the original. about 1/4 twist from bottoming out the light comes on.
I compared it with the Maglite brand drop in that I have in my old pelican backup, and with the original UK drop in it came with - Pelican at the top, UK drop in on the left, Q5 drop in on the right.
I like it. This is a really quick and easy (and Cheap!) way for people running halogen bulbs to upgrade, or people who just want a little more brightness out of their LED lights.
Here's the drop in I bought, cheap, but it took a while to get here -
DealExtreme: $12.42 Cree Q5 LED Drop-in Module (3.7V~18V Input)
Since I was in the mood (and I fried my primary the other day
ale: ) I mad a quick soft goodman handle for it. Worked really well on my dive sunday.
