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

On a more serious note, would it be possible to make a contact ring with raised areas in the right places so flat tops would work in it too ? Or am i overthinking again.

I think, flats tops will work with it now as is… sparkyDK. EDIT: If they are of proper length. :+1:

Sheriously, typical flat tops won’t work, and not much you could do to the ring, because as you tighten the battery tube, the cell tops are looping round on the ring, and where they stop, nobody knows.

SANYO GA’s are flat top, but unusual because the tops protrude higher than the wrapping - so they work, as long as the springs can handle the shorter length.

:+1: …. My apologies sparky. I was thinking only of the GA’s and totally left out the test of the important facts about most all other flat tops. :person_facepalming:

Again… my apologies. I shall now put on the Dunce Hat & sit myself in the corner the remainder of the night for the incorrect info I gave… that in all likelyhood could create confusion…… :person_facepalming: … :cry:

Thank goodness Tom caught it quickly & posted the correct info.

I’ll edit my post also…

Thats okay and not the cells i got for the Q8, i have a set of Sony’s VTC6 and a Set of the brown LG’s ( HG2 ), both flat top style i will have to do something about.

I am not quite sure if the GAs will be good without something done to them, as they have no button the spring should squease them less tight, so maybe a thud on the end cap would make connection go.
Then again as i understand the Q8 that shouldent matter if one or two cells momentarily get disconnected.

Man i cant wait to get my hands on this thing, just ordered a new sleeping bag tonight, so aside for a pice of tarp i am ready to go play survivalist in the forests of Denmark.
Forrest’s that will not be so dark when i am around, with or without the Q8

Yay! An updated list. Thanks.

Doh, just read about the switch to 3 LEDs, thats not happening is it? I certainly would vote against it but looks like I didn’t check back and see it in time to vote…

Thanks Mr.Scott. :+1:

What are you referring to might I ask?

+1 to that. Your a life saver Mr. Scott……

Yeah thanks again so much Mr.Scott!!

Wit? No switch to 3 LEDs

Modders have made smart modifications to the tail PCB so the tail can be used to load cells
The Boss1 had nubs and a good alignment where other companies go for a rotating tail PCB

I’m number 340 on the list.
Someone from work wants a stupidly bright light and I think will qualify.
Can I be added again so I get another one?
Thanks

I am happy that the light is “finished”!
But now that the luminus sst-40 is out (with real low Vf) i find it really a pity that we did not go for the dualfoodprint leadboard. Is there a plan for a GB in place for a dual leadboard?

You can make a plan, I once had a quote from Kerui Electronics for about 8 euro per board, 50 minimum. The contact is Sundy and she is on BLF under the name “leo ou”. The boards that they make seem high quality (my N119 boards come from there).

I do not have the funds to backup a project like that but i started a interest list to check if we could get enought people togeter to make it happen.

Q8 Dual footprint, quad LED copper DTP LEDboard interest List

This is a first check if enough people are interested in a Q8 Dual footprint, quad LED copper DTP LEDboard. The Board would be produced by Kerui Electronics for about 8 euro per board (50 pcs minimum order). It is only a interest list to check if we could get filled the minimum order. No commitments for now. The Board is available at LED4Powers Online Store! Board without LEDs = 3,97€ (https://led4power.com/product/l4p-blf-q8-40405050-38mm-dtp-direct-thermal-path-copper-mcpcb/) Board with 4 …

Hi, FNG here. Can you summarize the perceived advantages of what you're suggesting and outline any other changes that would be required?

Thanks!

Please put me down for one.

Pssst: the new LEDboard discussion is over there: Q8 Dual footprint, quad LED copper DTP LEDboard interest List

[TheOnlyDocc]

The advantages of a Dual footprint quad LED copper DTP LED board are that you can use all kind of LEDs in this light. At the moment you can only use LEDs that use a XP footprint like XPL, Nichia 309/319A, Nichia 219c. . … But no XM-L LEDs no SST-40 no XHP50.2 . . .
The new ledboard would allow you to use this LEDs. Some (with different Voltage) would require a driver change and spring PCB mod, some like XPL2, XM-L, SST-40 and some more would only require a LED change. And you may ask why would someone do this?
Many reasons! To get a more prefered color temperatur, or LEDs with a higher CRI, or more output, better throw . . .
Simple it gives you an easy option to mod your light.

what is a spring pcb mod?

Interesting, thanks for sharing that info…. :+1:
