Sofirn Q8 group buy (gb closed, but try PM to Sofirn for discount)

Hey guys, is there any discount code to get the BLF Q8 nearly the same price than the Sofirn Q8? I am not so happy with the beam of my Sofirn Q8, itā€™s a little bit too much throw in my view.

Yes:

Reloader?

Used to, donā€™t anymore but have boxes and boxes from when I did. CorBon made a really outstanding 200 gr uncontrolled expansion .45 that was really explosive when pushed hard. :slight_smile:

/\ ā€¦ Yep!! . :+1:

a change of LED will also fix that. :slight_smile:

Yep, but that seems to be a little bit too difficult for me at the moment. I am really not able to reflow-solderā€¦

@BlueSwordM: thx!

Apply a frosted film, or get a front lens that has a slight diffusion film (eg UCLens). That should make it slightly better.

Another project piece arrived late yesterday afternoon, I now have the Sofirn Q8 and a 4 pound chunk of Aluminum that are engaged to be married soon, maybe even today! :smiley:

The marriage of 4ā€x3.25ā€ 6061 bar stock to Sofirn Q8 in a private ceremony conducted by Reverend Dr. Frankendale took place this morning. The ceremony was about 3 1/2 hours, seems the 6061 had cold feet and needed some persuading.

The couple are now bonded and anxiously await the arrival of their little ones so they can begin their happy but exhausting life togetherā€¦

They plan a rather large family, expecting 12 Samsung LH351D 80 CRI 5000K and 4 Cree XP-L HI V3 3A to pair up with Noctigon Quad MCPCBā€™s and Ledil Angie optics. Should be a rather enlightening experience. :smiley:

Wowā€¦. that looks like the beginnings to a happy & bright future!! Best wishes to the happy couple as they anxiously await their ā€˜litterā€™ of chirenā€™ā€¦. :wink:

You can do gym with this big piece of Alu :slight_smile:
how much measure the Hole on the center of shelf?

Alen, the hole in the center is 14.4mm dia.

This 4ā€ x 3.25ā€ piece of 6061 was 4 lbs to begin with, more stock removal will be required for the emitters and then Iā€™ll cut fins and shape it so quite a bit of weight loss will still occur.

Edit: Just mating it to the Q8 took it down to 2 lbs and 13/16. So I have a pound a 3/16 of shavings off this chunk already. lol

Maybe, but then there is absolutely no reason to buy the BLF Q8 :wink:
And I cannot compare directly.

Got some more preparation done on the Q8 41 MAG today. Some new plans have a little bit of a twist, a center reflector to add some punch down the middle. Reflector from an X5, emitter to be determined but I am pretty sure which one Iā€™ll use. I plan to utilize the original driver with MOSFET and 7135 chip exchanged to match what I put on slave boards, so the original driver will be Master and I will have 4 slaves, the Master will run the center reflectored emitter and each of the slaves will run the 4 quadā€™s populated with Samsung emitters, for a total of 17 emitters. Projected output is in the 26,000 lumen range. :wink:

I know the pic here shows an HI in the middle, but that has changed. lol I will have to inset the MCPCB with the emitter in the center to allow for the deeper reflector, and I will have to cut the optics to meet the reflector but only a little, the cut curve will be where one of the 4 legs is so there will be that one sacrifice. Shouldnā€™t matter. The X5 reflector has an outer shelf for an o-ring that Iā€™m thinking will catch the optic and pin it to the glass lens, so the leg wonā€™t be missed. Will see. :wink:

Todayā€™s work ended up with the light in this condition. Ready to inset the center board, the 4 quads should be ready to go in. I have a glass lens that fits but Iā€™ll need to make some adjustments to the bezel as this lens is thicker than Iā€™d planned, may still go ahead and order a UCLp for maximum throughputā€¦

When Iā€™m nearer to finished Iā€™ll make aesthetic changes and cut cooling fins. :wink:

Looks amazing Dale. Nice machining on such large material on a smallish lathe. :beer:

This morning I inset the center MCPCB and reflector. I found a reflector that is a little smaller than the X5 I was going to use, this should allow me to use the 4 Ledil Angieā€™s on the Noctigon 33mm Quad MCPCBā€™s without cutting any on the optics. :slight_smile:

26mm Maxtoch copper MCPCB with XM footprint. Iā€™ll be using a de-domed SST-40 for the center punch. :smiley: As you can see, I started to cut the remaining shelf to be ready for the boards and optics but decided to wait til I had them in hand to be sure of the depth. I COULD disassemble my D4S and check this measurement but so far Iā€™m waiting. lol The shelf is at 10mm and the math makes me think I need 12.7mm, but I donā€™t know for sure so itā€™s wait time. The Maxtoch MCPCB and reflector required a 17.7mm depth, hence the inset.

Difficult to see in the picture but there is an AR coated glass lens in placeā€¦ the lens from my BTU Shocker just happens to fit perfectly albeit a bit thicker than Iā€™d planned. Will wait and not inset that for a perfect fit as I have sent a message to Chris to make a 95mm UCLpā€¦ :wink:

Edit: So yes, there will be 5 drivers to 5 ā€œlightsā€ within this one head, essentially 4 D4S lights with a modified 22mm tube light sporting a de-domed SST-40 for throw down the middle. Should be interesting to see what Sofirnā€™s carriers can do. 4 quads plus the one reflector, hence 41 in the name, and the MAG is a spinoff of both Magnum power and the acronym Most Audacious Guffaw, to poke fun of Giggles for the name of a flashlight. 25,000 lumens should get a pretty good gut laugh, yes?

You know this mod should have its own thread Dale. :slight_smile:

Yeah yeah yeah, simple little add on to the Q8. :stuck_out_tongue:

+1 ā€¦ It really should. . :+1: . :wink:
