Which could have been avoided if you would have clearly provided me the information I was clearly lacking.
Nobody can remember where all these old pictures come from. LOL 
just in case you guys need a new Q8 light.
Sofirn Q8 is available in our aliexpress store now! click me
Just place the order and leave a message saying your BLF ID before payment, our staff will modify the price for you, you need to refresh to find out!
Oh, one more thing, long tube for BLF Q8 will come out soon. 
Details of the new Sofirn Q8 version can be found here.
The big difference is that itās using xpl-hi in Cool White. A more minor change is that theyāve eliminated the flat sections on the battery tube. Itās now perfectly round.
what about a q8 in warm white 3000/4000k no interest ? cool white mehā¦
This light was intended to be CW from the beginning. 
WW is the third most popular. So for right now theyāre just trying to cover the first two. Maybe they will open up some more versions if this Sofirn version does well.
Weird question does anyone know where to purchase replacement o-rings from? Wanting to pickup a few spare tail cap o-rings just in case
Itās been asked and answered many times. Search is your friend.
Search is my friend I had been using it but I was typing āO-ringā not āo ringā so I wasnāt getting any returns of the provided link
Thank you tho
Thank you big time!
Hello,
I reflowed new leds on MCPCB, connected to driver (no reflector), turned on Moon as usual and one led didnĀ“t work, so reflowed again, assembled, but leds didnt turn on at all (no reflector). I tried to double click and got direct turbo, strobe etc, disconnected tube and from this moment everytime I connect the tube with the head I get direct turbo. The switch does not react to any click.
Could someone advice what went wrong? I cleaned everything, I checked all the wires, resolder the led wires on the driver and MCPCB, checked the wires of e-switch. When I soldered wires to the driver I accidentaly put an solder on other āconnection placesā for led + (there are four spots), but there is no solder bridge in to the wire, so I guess there should be a problem and I cleaned most of the solder with the wick.
I will try, but no guarantees.
What type of leds did you add? Itās not too uncommon for the moon level to be too low to light up an led. Moon level has 7 adjustments. If you mean the bottom of the ramp (moon level 3), then it might not be any big deal. As long as all 4 work as soon as you give it a bit of ramp up.
After reflowing the leds a 2nd time, they didnāt work at all, or just at the very lowest level?
When a light goes to max when you connect the battery, itās usually because of a short circuit. The positive of the battery goes straight to the mcpcb, then the mcpcb negative wire goes to the driver which controls the output. Any type of short on this negative wire will cause the leds to go full power. You might check if the reflector is shorting it.
The 4 positive led pads are all connected, you can use any of the 4. Same for the 4 negative pads.
Make sure no driver components are being shorted against the body.
Other than that, IDK.
JasonWW, thanks for your support and help ;).
I reflowed Samsung LH351D 4000K on a new MCPCB I bought on Ali (Sofirn original spare parts for Q8).
All four leds work on Turbo. I will check everything you advice in the evening.
First time (before 2th reflow) the 3 leds lighted up on Moon as expected. After 2th reflow, none of them, just a straight turbo after double click, there was no response on single click at all (only led switch turned on/off).
The e-switch is lit and react to on/off flashlight as expected.
Sounds like the 7135 is fried on the driverā¦ have no idea how it could have happened unless there was a short initiallyā¦.
Stupid question probably, what would happen if someone put in 4 xhp35 emitters for more throw would that work in this kind of light vs the xpl emitters?
In this case, it would just be better to swap the XPLs for XPL HIs for more throw.
You will get more lumens and more throw with XHP35HIs, but you will need a different battery configuration and a buck driver, which will cost quite a bit.
yea ok, makes sense. i feel the xpl are more then enough anyways.
Iāve not posted here in a while, but I think this is the right thread. Iāve been playing around programming my Q8 (Narsil v1.0 I think) and now have a couple of weird bugsā¦ Itād be great if someone could help me out with a fix.
If I am in ramping mode, and I press and hold then I get a flash of turbo (about 0.5 seconds), before it goes to moonlight. Itās as if the light forgets itās in ramping for half a second and goes to what it would in the mode groups setting before it remembers what it should do. I should also say this only happens if the light hasnāt been on in the last 10-20 seconds or so, if it was recently switched off then a long press will go straight to moonlight.
There is also a probably related issue when using mode groups. This happens in similar circumstances as described above (switching on after 10-20 seconds of not being used). Here, the light comes on in the correct mode, but the indicator (under switch) LED blinks three times and the light turns itself off again. If I click a second time during the three flashes then it will usually stay on instead. This one will also sometimes happen twice, i.e. another time after turning the light back on again. I havenāt seen it three times before though.
I had thought Iād caused this by changing a setting, but I have tried switching most back to factory resets and the problems are still there.
Does anyone have any idea what is going on?
