The switch is relatively soft, which we need, the light is heavy and it's not protected much. Being further inset would help.

I always lock out the Q8 when carrying it around in a bag, or whatever. Wonder if having the full fins above and below the switch would help. Above the switch, they are scooped out. Below the switch they are completely flattened. 

We made 100 posted reviews of 5 stars straight!  smile

Is there any warrenty for this light?

Well I suppose the usual warranty applies here with things from China, which unfortunately means issues that pop up fast will mean follow up from my side and thus Thorfire. If it cones up after months just post here or PM and we see what can be done.

Thanks and no worries if none are available. Smile


What Tom said, check M4DM4X for code and price.

Jason, I don’t know if this will help at all, but I immediately took it as a joke since many folks on the BLF prefer NW emitters. Those of us who couldn’t care less or prefer CW are in the minority or at least appear to be.

I never thought to do this, but when my brother got his he put his hand over the turbo beam and was surprised at how hot it was. So that it could start something smouldering comes as no surprise. Try the hand test yourself.

These polls tell the story of tint preferences on BLF:

http://budgetlightforum.com/node/52979

NW is the overwhelming majority. Both polls have the CW tints at 11%.

I went back 4 pages and still could not figure out what your referring to.

A thread just with all the parts and accessories people find in one place would be pretty nice, and yet I’m not volunteering to maintain one.

I’m not volunteering either (grin) but I just PM’d our host SB asking if there’s a way to download an entire topic rather than page by page, for the kind of editing pass that would need.

I prefer copying an entire document and then throwing away all the text I don’t want, rather than cutting and pasting out of the document, to assemble a condensed summary.

Or maybe there’s a magic computerized way to hilight desired text and “send it to another file” with some record of where it came from. Kind of like a hypertext thingy. Just wishing aloud here.

Thanks for the info. I see maybe 6 stores on Aliexpress that carry it. I put them all on my wish list. I think they let you know when something on your wish list goes on sale. Plus I’ll check all the prices on 11/11. I’m sure I can get a good deal on it.

Well, they did not let me know if any of these chargers went on sale, but I just checked and the above store has it at $41 instead of $31. Sad

I checked all around and found it for $32 on this store if anyone is interested.

I sent a PM to SB asking if there’s a way to download the whole thread (rather than one page at a time) to edit the content down and leave only the info on accessories to repost.
With a pointer to the first suggestion about this above.
Not volunteering, mind ya. But I’ve wondered before about this.

They do that anyway, once you take them out of the dark. Once dark they hibernate after a few days, still keeping time, for a year or more. Then wake up back where they were, with some light. If capable they then re-lock onto RF time signals, but not important, my two run for a year and are still within 30 seconds. Great devices.

Coated lens is an odd one, I didn’t think I had one, but looked vary carefully. I do, but it is in upside down, seemingly single-side coated, not a concern. May turn it around the proper way to try to see any difference, but frankly not bothered.

CS screws are only in first batch AFAIK.

Since the torch is currently sold out, perhaps batch 3 is on the way, that might trigger more excitement depending whether any more changes are coming. I hope they are, continuous product improvement is in my blood, not stasis.

I just received my order of brass screws from this same seller yesterday. They were slightly oily and all but 1 have at least 1 hairline crack. I cleaned them up with a degreaser and will use the best 6. Should be okay.

Which 6 should be replaced?
The driver screws (2) and tail pcb screws (4). M2.5×5mm screw works, at least for 2nd batch Q8s.

 Well, I thought I liked neutral.  I have some T6, color bin 4C I think, or that's what fastech said, xm-l2. As I recall that bin has a minimum cri of around 80% maybe. I must say I much prefer them to the Q8, which is significantly "cooler", but that's not so much the issue as it just seems colors are slightly flat in comparison.  As LED's go the Q8 is pretty good still, far better than cool whites, but not as nice as my T6's.  Probably more lumens though.  Considering replacing with a warm xp-l2 if I ever feel like blowing the cash on them.

QUESTION FOR BANGGOOD

Looking to follow up on the status of my order. It has tracking from last month for the 22nd through 25th, and then nothing since then. The “expected” delivery date was over a week ago, according to their own site. Not sure what all information I need to provide to TM.

My last one left China 23 October headed for Kennedy in NY. There was no Tracking update at all till 9 November when it was handed over to the USPS.
So it just sat somewhere in NYC for over 2 weeks. Facepalm
Hopefully yours will show some movement also….. Wink

At least yours has tracking state side. The last tracking from mine was still in China almost three weeks ago now.

So just checked, and those fasttech xm-l2 T6-4Cs are 4200-4500 where the Q8 is XP-L 4750-5000, so yeah a little cooler.  The bin datasheets from cree show that both of those should be minimum 70 cri/typical 75.  I definitely prefer the T6. Whatever the reason it feels more natural to me.

To those that have lights lost in the mail, contact bandgood and they will make it right. DHL managed to loose mine (tracking even shows it). They have a replacement on its way. It will take a few extra days but at least it is coming.

Haha, well normal people probably don't modify flashlights, but as for the led's those t6 4c's are pretty popular from comments I've seen, and have 28 reviews on fasttech, a lot more than any xm-l2 in any or all 3-bin's, including U2 3c or 3b, and the U2 1-bins have a whole 1 review.

Hah, Flintrock may be weird, but not because of that. Lots of people prefer 4300K-ish tints over 4800K-ish tints. The 4000K Nichia is particularly popular around here.

IIRC, the XM-L2 also might have somewhat less variation across the beam, which would make it look better, but I don’t recall for sure. XM-L2 has a full and smooth dome, while the uneven XP-L dome got shaved on the edges to make it fit an XP-sized pad. It’s great that it fits the smaller pad, and it’s easier to do mods with an XP footprint, but the emitter itself was originally designed for a different dome.

Hmmmm…. when did you order yours? (my was ordered 19 October)

My last one did not/is not coming by FedEx SmartPost… it is USPS all the way once it hits the USA.

This may not help, but if your Tracking Number starts & ends with letters like this… LS03@@@@@48CN …… plug it in here….. https://tools.usps.com/go/TrackConfirmAction_input …. and see if you get any results.
You may have done this already, but if you haven’t it can’t hurt to try.

Guys

I just want to mention that I placed my order last month on 22/10 using the GB code provided to me by “The Miller” in early September that supposedly expires end of Sept, and it still worked for me last month. Assuming the code is unique, perhaps those who did not end up placing an order can still try it out?

EDIT: I opted for FREE SHIPPING. The order was dispatched on 24/10, and surprisingly I received it in Australia right on 2 weeks on 07/11.

I notice the BLF Q8 is on pre-order now at Banggood. I’m wondering if the next batch of BLF Q8 might have other issues that the first batch seem to experience. Also, is there any updated firmware (I saw mentions of NarsilM v1.1 or 1.2, not sure what are the differences) for the BLF Q8 — what firmware is the latest currently installed (or scheduled for next batch release)?

Another question, it’s mentioned that true flat-tops may not work (eg. original Samsung INR18650-30Q), but raised flat-tops like the LG HG2 might work. How about plain Panasonic NCR18650B? It looks like I may not be able to order any more 18650s — all the previous online shops, including the ones from AliExpress) that formerly ship to our country, now indicate “cannot deliver to the Philippines”.

~~~~~

Also wondering, what’s the difference of the BLF Q8’s light output compared to say 4xBLF A6 3D-tint (eg. tie up 4 of these in a square pattern), and let’s say put the 4xBLF A6 into Turbo mode — compare it with BLF Q8 at Turbo mode — will they have similar light output using same batteries (perhaps the beam pattern will differ)? The BLF A6 3D-tint uses the same emitter as the BLF Q8, isn’t it?

I know many here put solder blobs on their flat top batteries. If I choose not to do this, does anyone have any links to recommended magnet slabs to use?

Hi ssschen

Remember that in the Q8, unlike devices with single battery or battery carriers, the top of the batteries will be rotating around the contact ring, ie there will be a lot of sideways friction on the positive pole as the battery tube is screwed in. This could dislodge a magnet, potentially causing a short. It may be a bit risky going the magnet route.

Beam me up!

The Q8 is for a great deal not unlike 4xBLFA6 taped together, same battery/led set-up, but there are nuances: the surface area of the 4xA6 is a comparable so the maximum sustainable output is also similar (~2000lm at room temp/no airflow, if you like your flashlight hot), but the heat path and amount of metal in the right places is way better in the Q8, so while the 4xA6 must step down at 40 seconds, the Q8 with more soaking capability takes more than 3 minutes to get to the same temperature. That makes the Q8 also easier on the leds so I expect them to live longer.

Sorry, I was thinking of too short springs and magnets as spacers.

You can’t put any type of magnet on the positive end on the Q8 or any similar design flashlight. You either need proud positive posts or add solder blobs. There’s no other alternatives.
