oh the gt is def foe me, the thrower xhp 35
and your right, that tn 40 will light my cigarette after about 3 min on turbo, if that
im sure the gt if it had the 70 in it, would run full bore forever b4 getting warm
good point :+1:
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):
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.

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
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.

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

Waiting for the dark. Driver autopsy to follow later
