>>>>>Hmm… Have you tried taking off the head?
Hmmm is my thought exactly. By head, do you mean the zoom lense holder? It will not come off without getting the pill out, like most zoomers, or the ones I have seen. Thanks again for all the help, BTW.
I’ve tried pushing from the back. Nothing except a red face.
Looks like I might have to blast afterall.
Lap a slug? Okay tried it. Didn’t do any good, plus it tasted awful. :8)
I just looked at the picture again and you need to take off the white spacer and under that there will probably be some holes for tweezers/pliers.
>>>>you need to take off the white spacer and under that there will probably be some holes for tweezers/pliers
Yup, I may have to blast. 
The white plastic spacer — or whatever it is — is not as flimsy as first thought. It is about 1/32nd of inch thick and seemingly made from the stongest plastic ever developed. It ain’t moving.
There’s not a lot of room in there without risking the emitter, but i can get an exacto tip under there and pried like the dickens (no offense to Charles) and VOILA!
Nothing.
I will keep working on it but it almost feels like it is glued to the emitter base.
There has to be some way to unscrew it right? This wouldn’t be press fit if I REALLY REALLY press from the back?
the bore of the pill is not tapered on mine. Round copper bar stock, turned +.001” OD, heated the aluminium pill (sans emitter and driver board), then pressed in the copper slug on my bench vice. Turned some iron bar stock for a completely square surface, then used that to sand the pill. Sand the back side of the emitter star, as well (800 - 1000 grit). Then, use lapping compound on both.
When you have finished that (to the extent of your liking), mix up a drop of 2-part thermal epoxy (I prefer “silver arctic”), and squeeze the emitter on, tightly. Drill new holes for the wires, put in the 17mm driver of your choice, solder the leads, and reassemble.
I’ll provide pictures as soon as I get around buying a new camera.
s.:
the first run of Sipik SK98 weren’t press-in pills. They were screwed in, with proper threads.
Should they really have changed the design?
I need to order a couple more to make sure. After all, I know enough people who’d want and need a decent torch (although I would not trust them with rechargeable Li-Ions - rather take the risk of 2xCR123A with a corresponding driver)
it is not a spacer - it actually keeps the Cree LED on its aluminium star-shaped board in place.
Looky there, lots of good reading: ITS HERE! SIPIK SK98 - A 18650 based Sipik SK68 with an XML!
I'm guessing you mean to hold the star down as the LED is already re-flowed onto the board. Even that isn't always true on my Marsfire STL-V2 there is a white plastic spacer for centering it.
Just to clear up any misunderstandings, MY pictured pill is NOT from a 98 clone. It is this light, which is actually pretty good zoomwise execpt for the HORRIBLE PWM flickering on the lowest settings.
This is the one I would like to change out. Too much happening in this thread for my molasses-filled head to keep it all straight.
So somehow, this white spacer thingie has to come out? Kayrect?
The pill looks like this from the front:
So the consensus is that after somehow blasting out the white spacer, there will be notches under here to twist the pill and extract it?
That is my best guess as to what to do. I doubt it is press fit so they have to have a way to screw it in.
Either that or you have to unscrew it from the back? Are there any threads in the back. (I'll post pics in a few minutes)
Like this.
Take the pill out, pop the driver board off the bottom, and push the star out from underneath.
He is trying to figure out how to do that.
Hmmm, I’d be drilling a couple of indentations in the top, where you usually find them (and being very careful of stray bits of aluminium of course). Could even do that with a tiny screwdriver with a little patience.
I'm sure there is a way to unscrew it the question is whether it is under the plastic spacer or at the bottom of the pill.
>>>>>>I’m sure there is a way to unscrew it the question is whether it is under the plastic spacer or at the bottom of the pill.
Well, it ain’t at the top o’ the pill under the spacer, at least nothing I can see.
I carefully sliced and sliced and sliced and sliced until I was able to cut a chunk outta the washer; which was like cutting depleted uranium or something. I think it was delrin or some other super plastic.
If I look through the battery compartment, I can now see the front of the alumnium pill, i.e., there are NO ridges, notches, holes or ANYTHING that would allow me to turn this thing. Unless youse guyz can see sumthin in there? No threads in the back.
Tried (VERY hard) to push the pill through from the back. Didn’t budge. Before I start whacking on it with a little hammer and a mini chisel (from the batt compartment, trying to push it out the front), has ANYONE ever heard of one of these being press fit? Could it be glued in? I don’t see em welding aluminum; that ain’t gonna happen.
So oh great BLFers with tons more experience than me, how does it come out?
Well, at least I don’t have to worry about the PWM flicker any more! 
NOTHING is ever easy, you know that right
Wow, that is surprising. In that case the thing to do would probably be what cainn suggested either that or try to wire up the driver without removing the pill.
I expanded a pair of hemostats INSIDE the pill, applying as much pressure as possible to the inside walls. Doing that, I was able to back it out.
Too lazy to take a picture now. The pill is threaded not press fit.
There are NO notches or ridges to help in turning this thing to get it out.
NOW — since I am new to this — what do i need for measurements to get a replacement that won’t flicker and where is the best place to get one.
I have to get a replacement now. I spent all afternoon on the &*&&%&* thing.
Thanks to everyone. Would have given up hours ago.
Completely off topic, just rescued my three handheld light meters from a closet last night, so I will be doing some lux readings when it’s time! I’m getting serious now.
Congrats! Did you measure the driver?
>>>>>>Congrats! Did you measure the driver?
I have read much on BLF, but i’m a little hazy what measurements I need here …. The circular PCB is 17mm in diameter.
1. That is the driver, kayrect?
2. I reuse the threaded aluminum “pill?”
3. I can reuse the xml emitter? Just resolder that to the existing wire leads or ……
4. I read somewhere that I should use heavier wire for the emitter to PCB? If so, what gauge?
5. And the best place to get the new driver?
6. Anything particular I should look for in a new driver?
I am SO psyched to get this flash working with a non-flickering beam!!!
Thanks you everyone, especially scaru, who is now in my will, which means a mickey d’s FULL dinner could be his when I cash out. We’re talking BIG BUCKS inheritance! No charge for as much extra ketchup as you want! It’s the least I can do for all your help!
I like this little light. Very light in weight, sturdy, good machining, nice color, good zoom, etc. …. So I don’t have to get a new light at all. I can use this one with a good non-flickering beam!! YEEEEE HAAAAA!!!
Ok, so yes 17mm is the driver size.
1. Yes.
2. Yes, however it may be smart to add some more heatsinking in there. You don't have to but it looks like it could use it.
3. Yes, you can reuse the xml.
4. I'm not quite positive on that so I'll let someone else answer that. I'm guessing the currents wires would be fine.
5. You could order it from any site that sells drivers.
6. Since you don't want flickering you want something with a high pwm frequency. For that you should read reviews of drivers to find that out. My personal recommendation is a driver from E1320 it uses a high pwm frequency and has 5 modes. Firefly-lo-med-high-turbo and it has memory. It also ships from the US so you will get your hands on it sooner.
Glad to have helped. :)
Here a link to E1320's account is.

Edit: You definitely need to add some more heatsinking. The easiest way to do that would be OL's method using copper fittings.
I'd avoid saying "flickering " that generally means something else ..You had me very confused.. flickering means a bad contact problem .. usually in the tailcap or head ... what you're talking about is low PWM or bad pwm ..
The most obvious answer was to have taken a little drill and drilled 2 small holes in the edges of the pill ...
the hollow pill is a horrible lack of heatsink material and the fact a light gets hot is a good thing .. it means it's working ... the entire light should become the heat sink .. or it means you're overdriving the hell out of a light..modding a cheap light is somewhat problematic since they use cheaper materials and are cutting corners .
I'd be looking for a better host to work with ..I like edi-t lights .. the emitters are older but the bodies are generally pretty nice
