Q8, PMS SEND TO THOSE WITH ISSUES BLF soda can light

^ shelf checked more than a year ago by heaps of modders, result: :+1: ( :weary: )

The two holes in the shelf are not threaded, in the first batch the ledboard was screwed down from above forcing (so sort of self-tapping) the screws in the holes, not elegant, wished it to be different but it worked. In the later batches with the screws coming from the underside the holes were large enough to pass the screws unhindered.

I just found out that the picture in Alen's post is not his light. I was under the impression it was a recently made unit. So I searched the image and found the same photo posted by djozz in the development phase of the Q8. Geez, louise. I wish folks would reference the source of photos when the photos are not their own. A little context goes a long way to understanding a situation.

Please disregard all my concerns mentioned above.

Much ado about nothing.

wisdom is a step behind passion

Yep…+1 to both. :wink:

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 :smiley:

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. :wink:

Details of the new Sofirn Q8 version can be found here.

The big difference is that it’s using xpl-hi in Cool White. A more minor change is that they’ve eliminated the flat sections on the battery tube. It’s now perfectly round.

what about a q8 in warm white 3000/4000k no interest ? cool white meh…

This light was intended to be CW from the beginning. :beer:

WW is the third most popular. So for right now they’re 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

It’s been asked and answered many times. Search is your friend.

These work on both ends of the tube - I have ordered and used them

O-rings

Search is my friend I had been using it but I was typing “O-ring” not “o ring” so I wasn’t 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 didn´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 “connection places” 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? It’s 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 didn’t work at all, or just at the very lowest level?

When a light goes to max when you connect the battery, it’s 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.
