- The 3rd batch of PM’s will go out in the next couple days! Please check the new thread for more info.
[23 Mar 2018] Neal and Lumintop are back in full contact now after CNY. We are sorting through issues and preparing for the next batch as quickly as possible. If you have an open issue please fill out the BLF GT outstanding issues survey
Please only fill out survey one time and only if you have already paid for an order and have an issue. Thanks.
[20 Mar 2018] Due to this threads massive size it was causing the BLF server to break down and/or be very slow. Please go to the link above and subscribe to the new thread (bottom of post #1) or just post in it to be automatically subscribed. Subscribe to the new thread for the latest news.
[14 Mar 2018] Pi Day! M4D M4X is putting together a list of active issues for the GT. This is ONLY for those that have Placed an order and have an outstanding issues that needs to be addressed. This is NOT for tracking number requests, these will be handled separately. Please only fill this out if you have a real issue that needs to be addressed, I don’t want it to get bogged down with other stuff.
The results of this survey will be compiled into a list and sent to Neal to be addressed. Please be as specific as possible when filling it out but also try to keep to the important information to make it easier for Neal to understand. Remember, english is not his first language.
BLF GT outstanding issues survey
Once these issues are fixed we will proceed with the GB, shipping should be much faster since lumintop is stockpiling the reflectors.
[12 Mar 2018] Lumintop and Neal sent out the final 50 orders from the existing orders today, tracking numbers should hopefully be available by the end of the week.
[11 Feb 2018] Lumintop and Neal worked together to send off a final 185 lights before the Chinese new years celebration. China will be shut down for the next few weeks and we do not expect any updates or news until the end of the month. So please remain calm and hold your questions until the end of the month. At that time we will sort out the remaining orders that have not been shipped and try to deal with any outstanding issues. We expect to send out the next batch of PM’s around the end of the month’ish
[3 Feb 2018] Lumintop graciously agreed to pay for the extra shipping costs out of their own pocket to some countries. Our end of the deal is that we will charge these costs up front with the next batch of orders. Only the smaller / remote countries are effects for the most part.
[30 Jan 2018] The 3rd batch of payment PM’s will be postponed until after the China New year to minimize wait time. Plus nothing will happen until after it is over anyways.
[30 Jan 2018] Lumintop should have the registered mail issues sorted out and is hoping to ship most of the existing orders before the Chinese new year celebration that starts next week. This assumes that enough reflectors show up and they are good enough quality.

[10 Jan 2018] The PM’s for this account “Team-Giggles” have been disabled for the time being as no one actively monitors them right now. Please contact Neal or Texas_Ace with any questions instead.
[6 Jan 2018] The Group Buy is officially closed! The lights will go on sale with the normal Lumintop outlets after the GB orders are complete sometime in the next few months. The retail price will be $250. Thanks to everyone that made this possible!
[5 Jan 2018] BREAKING NEWS The group-buy will end today. If you do not have ‘I want one post’ in this thread by the end of today (no idea which timezone], you will not be able to buy the GT at the group-buy price.

[27 Dec 2017] The GT started to ship. Shipping will continue as they roll off the assembly line. Production rate is about 200 units per week. The first two batches shipped to the US (for logistical reasons).
From our omnipresent JasonWW:
LATEST NEWS
A 6th shipment of 50 lights (the last of the current orders) went out on March 13.Appearantly it was a smaller batch than 50 as more lights are shipping during the week of March 19-23.Neal is sending out tracking numbers. Some packages have already started arriving.
The next group (3rd batch) to purchase lights (#1050 and up on the list or who signed up after 10/23/17) will get their PM/ emails in March (Maybe. Keep reading for details). This minimizes wait time and also gives Neal time to finish up the last shipments from the people who already paid.
Texas_Ace will decide when the PM’s go out. It should be some time after ALL the current orders are shipped out and any missing or incorrect orders are corrected. We should get a few days advance notice.
You can see if you have a tracking number for this 5th shipment by going HERE and filling out the form.
A 5th shipment of 185 lights went out on Feb 9th. This includes registered packages. So this means about 800 of the 850 lights have shipped. The next shipment of reflectors should take care of the last 50 orders.
I moved 1st, 2nd, 3rd and 4th shipment details to post #12000
DHL shipping was very fast and is recommended for all USA buyers in the future.
The “slowish” shipping is due to the large reflectors being slow to produce. Lumintop is only receiving about 150 reflectors per week. So we should see about 150 lights ship every week.
Of the first 1049 people on the list that have been able to pay, about 850 have ordered.
Initial quality has been fantastic. A handful of people have gotten opaque black switch covers instead of translucent black. Replacement switch covers are being sent on a case by case basis.

Runtimes with 4 cells only:
MRsDNF:
Talking about things happening here is a run time chart with the BLF GT proto Narsil running Two Amps at the end of ramping.
The runs were stopped when the low voltage kicked in for the first time.
(This is a battery comparison at 2A. Note that the 3500mah cells have extended run times after it falls out of regulation, blue line.)
MRsDNF:
This chart is a comparison running the BLF GT on high, the original Narsil at 2.5 amps and the proto Narsil at 2 amps. Both runs were with 30Q batteries. (This test is only about comparing 2A runtimes to 2.5A. The 2A red line stays in regulation much longer.)
Texas_Ace:
Also remember that those runtime tests are with the short tube 4 cell version, 45 mins from 4 cells before even dropping out of regulation! That is properly good.
So expect about double that from a long tube with a full 8 cells.
About 1.5 hours of full powered runtime and another ~1.5 hours before it hits LVP.

Nice! Was about time though
And ofc i am interested
XHP35Hi high CRI vs a good W2/3…especialy since it would be a long term project…aint sure about that, especialy with those new coming xpl2 and future xpl2 hi
in a 94mm the picture under so-so reflector a dded V5 deals nearly 650k cds at 5 amps
I have still to dismantle the TN42 to test it out with a nice w2
Nice idea! But 8 cells?

I’m ok with 8 cells, but it better be one hell of a thrower!
You guys planning on cracking the 1Mcd with that 12 cm reflector?
If the price is decent…I’m in!
Cheers
Nico
Great !
I think too 8 cells are a lot . 4 are ok
Also , count me in too , for any help the team needs .
Edit : Please don’t start an interest list , it will turn into chaos with the expected results

Dang dude, you are really pushing the limits here. Two custom and unusual light projects at the same time! Heck yeah, I am in!
Keep this up and make the work… you will generate some real BLF envy.

I am in
Im in this one as well!
The debate is lumen vs throw. It will be a big light so will we be happy with a 1400 lumen XP-L HI and try to hit 1Mcd?, or will we settle for 700kcd with a 2000+ lumen XHP35?, or go 4000 lumen / 300kcd with a XHP70? (numbers are a very fast guess)
My first feeling is that in a light this big I expect more than 2000 lumen, even though that implies that maximum throw for the reflector will not be reached.

I’m in for a couple high quality hosts IF you can get them made first, before the multitude of requests and idea’s and other BS start’s flowing in, I have the drivers, boards and LED’s already.
It can’t be that hard just copy the TN42 with a bigger reflector and keep the carrier 4S, easy peasy, then just slap BLF on the side? If you have too?
Let the games begin!

Lithium Ion Battery Safety
Oh yeah, I’m in! Shine on.
Wow, I am in. Depending on price.
+1
It is usually a compromise between lumens and lux. One direction to go is multiple reflectors/emitters, like a bigger TM16GT. This way one can get lumens and lux as long as the separate reflectors make good use of the available area and are driven well.
Too much unsure so I will start keeping the interest list later down the path
For now just think along
Basic ways the same as the Q8:
Designs open source
No money/profit for the team, just the fun of doing it
Open about and for as much as possible
It is done when it is done

Cool!
I’m interested too…but…where does it end, lol? Instead of starting with a 120mm reflector why not a 160mm? It’s best to start big instead of small due to the fact that newer, bigger, and better will be out before you know it. It’ll take a little longer for a manufacturer to best it if you build it big. The Eagletac M25C2 Turbo that I modded with a fet and dedomed XM-L2 U4 1A has a 92mm reflector and does 636,763cd. My wife calls it the plunger because the head is so much bigger than the body but it throws like crazy. I’d still like to be able to hold the light with one hand though, so 160mm may be out of the question…unless a handle is added…
CST90 (Inner diameter 117mm, Outer 128mm). Minimum order quantity, 100.
Just need to get them to not cut out the base like above.
I’m in!
Would prefer 4 cells instead of 8 (in fact not interested at all if 8 cells). Go for max lux over lumens (plenty of flooders or compromise beam lights around).

Is it not too deep? It’s just a question…I’m not into the whole measuring the angle of the beam thing…it just looks really deep to me. I guess that would product more of a spot?…than spill?
