Well, I did not have that situation before! Maybe sometimes hole for emitter was a bit larger but they always fit reflector perfectly with no wiggle room whatsoever.
This looks like XPL HI and 9mm reflector, I would do this: take a centering washer for osram leds and with fine sandpaper expand the hole slightly until it fits snugly, that will fix the problem with led-fit but I do not see the way to fix reflector wigling! check other washers you have, I never had that situation.
Potting is probably only something needed with a really high caliber rifle, the C8’s used up to a .308 have had no issues over 4 years.
I can’t say I’ve had this issue with the C8+, it fits quite nicely,also tapping has no effect.
Maybe the reflector was made a little too large
Have run a C8-2 (KDLitker), and Sofirn’s: C8T, C8A, and older version C8F (18650) with standard drivers (but larger springs replaced in a few for a tighter battery hold). Most did time over a 270 with zero issues.
Funtastic,
how is this flashlight coming along 
It’s in production, maybe 2 months away. It’ll be a 2021 release I’d say
2021 will be a good year :+1:
Any updates?
Simon has a sample but there’s an issue with the reflector so have to wait
Was this released?
my two cents is that it should have little to no grip. A bumpy grip for me means it’s harder to wipe down and get clean. If I need any grip I slap some hockey tape on it which is easy to remove.
I have a couple samples and it performs incredibly well. The issue that needs to be corrected is very poor focus, the reflector needs lifting higher when using the Osram LEDs. Simon is waiting for some final measurements from me before ordering new thicker gaskets.
I haven’t tested the CULPM1 yet, but below are the range measurements I get using the CSLNM1
Red - 820m
Green - 1,674m
Body diameter ended up being 26mm instead of 27mm which I absolutely love since it’ll still fit most 25.4mm mounting brackets. I hope Simon gets into making lighter weight models because there’ll be many who’d prefer them. The L21A is better for heat dissipation, but felt quite bulky, this L21B is only 210g vs 354g. I just wish he’d get a little more creative with the naming as I’m sure many potential customers would be put off from the confusion. I mean there’s the C8+ and the 21700 version is called the M21A, how confusing is that
It’s really decent. This will give all hunting brands out there a real run for their money.
Could you show us this sample? Next to the L21A and C8+/M21A?
Is it available from Simon?
I mean, the prices in your store are a bit high compared to Simon
Prices are very high if you’re looking at them in usd, but it’s nzd 
although I still need to make a living somehow
New Zealand customers only as exporting is problematic. I give lifetime upgrades and free labour on repairs after 1 yr warranty to make the prices worth it
The focus is bad without height adjustment of the reflector and so I’ve told Simon the thickness gasket of what’s needed.
Oh and btw, I don’t just resell as is, I install dual springs, align LED, tighten screws and retaining rings, and clean all contacts
Ah, thanks for the explanation, forgot that its NZ$ which is obvious different than US$.
No need to excuse, i understand that its part of your business and you have to make a living.
Was just hoping that BLF enthusiasts can buy it from Simon, since most of us are familiar with Convoy and modding.
Just flick Simon a message and ask for it he has them ready, but just with the focus issue.
First look at the performance using the Osram CSLNM1 Red
Would you be able to do a store demo of L21B STF40 VS Osram?
