My rough guestimate on the throw for this light is 1,100 to 1,300 kcd with a good stock XHP35 HI. djozz had a good estimate posted way back based on the TN42's performance and it's reflector size, again, assuming we got the optics and LED as good as the TN42's, and the driver producing the amps expected.

1,200 kcd is a rated distance of 2,191 meters, or 7,188 feet, or 1.36 miles. Formula for candela to distance (meters):

SQRT (1200*4), from here: http://flashlightwiki.com/Light_Output_Measurements:

Throw

An actual distance for throw can be directly calculated from the candela value and will be given in meters. The FL-1 standard does just this by providing a light intensity reading in candela and converting this to throw in meters by calculated the distance at which the light will generate 0.25 lux. Throw is just the square root of the light intensity in candela divided by 0.25 lux which gives meters.

a TN40 with 8700 lumens, is that a typo?

One of the the TN40vn spec’s does 500k lux and 8,700 lumens. It’s a crazy high output thrower for sure.

Just checked it out. Uses XHP35 HI. Pretty potent combination.

On the other hand, 4 well-driven dedomed XPL V6 might get you 6500 lumens out-the-front, with a bit better throw than the XHP35 HI.

Ah, I was getting the TN40 mixed up with another light, I thought it was a single LED thrower. I see now it is a quad LED, that makes way more sense.

As you might could tell, I don’t pay much attention to “brand name lights”.

I want to buy a used video card, GTX 650 or better preferred.

I wouldn’t mind seeing a quad sized GT like a bigger TN40
but first the GT then the GM Giga Monster if it is cool to do

yeah, 10,000 lumens, and 1 mill lux would be a show stopper !

vn modded
tk61 ice cold for days
tn42, warm after 5 minutes or so, still useable after 10 solid minutes
tn40, warm in 1 minute, ouch thats hot, in 3 minutes, cigar lighter or personal heater in the winter in 4 minutes

Hehe, I’m giving in to the pressure. Could I be put down for a second GT please? I’m holding back the urge for a 3rd.

Funny you should mention that – #1 of the approval prototypes is just in! I have had a stupid grin on my face for the last two hours. This thing is ridiculously huge – I love it!

First impressions are great. These are obvious prototypes, few small surface imperfections on mine. But the anodizing, machining, fit, finish is excellent otherwise. Mine is a shorty, but the head is less heavy than expected and the imbalance is not too bad. Should note that the LED bin/tint is unknown. Would have to guess a 2B or 1C for the tint, cool with a hint of green. The production units will have 3D.

Cell holder is pretty nice, solid and ergonomic for swapping out cells.

NarsilM was not set to the default ramping mode and was confusing for a second. Set it back to ramping and did not look back.

Ran it against a stock Olight M3Xs (250 kcd) and an L2 host fitted with an XPL-Hi and FET driver. Measured at 10 m:

L2: 1430 lux, 143 kcd, 756 m
M3Xs: 1960 lux, 196 kcd, 885 m
GT: 8850 lux, 885 kcd, 1881 m

EDIT: Those cells were only half charged and sagging enough for the buck to drop out of regulation.
A set of 30Qs at 4 V gives 10600 lux at 10 m. That is 1.06 Mcd or 2.059 km of throw.

Had it running for several minutes while taking measurements. This thing is a beast, body/head did not even get luke-warm.

Out of the box:

Some BLF favorites for scale:

My closest contender for throw:

My closest contender for size:

Details:

Battery tube and end cap. Someone had the cell-holder in backwards at some time, some brass transfer inside the cap:

Cell holder, very nice design. Driver end:

Back end, to mate with second holder:

Springs look just about perfect for both protected and unprotected cells. These protected PFs have about 3 mm compression left:

High quality PCB ends:

Driver, conventional retaining ring:

Waiting for the dark. Driver autopsy to follow later

amazing… only thing i can say. except that the lux really falls short of the expected 1.2 mil.

I am smiling in anticipation of my proto showing up tomorrow or the next day. It looks great.

Curious what the throw numbers will do at further distance, with a reflector this large it could take some distance for the beam to truly focus / converge.

I want to buy a used video card, GTX 650 or better preferred.

Do not put too much on my numbers yet. That meter shorts the M3xs as well.

Trees at the end of the lot is 500 ft/150 m away. ISO100, 2s exposure, manual white balance, unedited. Set of so-so cells from my M6, photo does not do it justice:

that’s actually very nice, just the rightsize at such a distance. definitely not going to have to worry about blinding people(not those who shouldn’t be expecting a beam in their face anyway haha) when pointing somewhere further downrange.

Hold the press. My 3 meters agree, but the cells were sagging and the buck was not in regulation.

A set of 30Qs at 4 V gives 10600 lux at 10 m. That is 1.06 Mcd or 2.059 km of throw.

Finally dark. Exposure increased to 5 s, and I think this is closer to what the eye sees. Tree at 500 ft / 150 m.

Do you have a picture of the short light being hand-held ? Also, is the short tube going to be available as an accessory?

Could you please add me to the list for one. Thank you.

Thanks DEL for the update. Hopefully I’ll have a stupid grin on my face tonight.

My current and or voltage measurements are only relevent to anything that I measure.

Don’t panic. There’s plenty of time and no one is taking money at this time. Maybe you can get a fellow countryman to walk you through it.
