Who knows the specs of Boeing landing lights?
Vn? Haha.
Vn? Haha.
From car headlight to airplane lights. Where does it stop???
Right forum. Wrong thread.And this is the forum about all lightsources.
Why does other persons compare footbal, with hockey?
Right forum. Wrong thread.
Out of interest here,can the body from the tk61 be removed off head,the body of the tk75 and extension fitted to the tk61 so all looks same,just a thought if own both,that way can all be in keeping............if that mattered to peeps of course:thumbsup:
Great pics guys:twothumbs
They measure their lights according ANSI standards. A company needs to follow rules given by ANSI to say they follow the ANSI standard. For more info I would suggest you visit the website of ANSI.Can i expect that the stock version really gives 170 kcD? And not much lower?
Like the manufacterer state of 170 kcD, as read in the manual of the TK61, is that really measured by Fenix, or how they come at this measure?
Is that really measured? Or is it selltalk.
I read here on CPF, that a TK61 owner only measures 130 kcD on his TK61, instead of 170 kcD.
Thats dissapointing isnt it? Not much more intensity than the 2900 lumen TK75, and the same beamintensity of the RC40.
When you read the light has 170 kcD, than you want 170 kcD, and not only 130 kcD.
Please explain me more. Lucky mine is more than 170 kcD.
As lux is the lumens per square meter, generally, you can assume that the change in cd will be proportional to the lumen output for the same light...IE: If you cut the lumens in half, you are cutting the cd in half.
To clarify one part above - if a light has a cd of 170,000, that is the cd, NOT the K cd. The k stands for 1,000, so a k cd is a thousand cd.
That means you can EITHER say a light has 170 k cd, or 170,000 cd
So if 100% output is 1,000 L at 170,000 cd :
At 20 lumens, that's 2% of the 1000 L = 2% of the 170,000 cd = 3,400 cd.
At 150 L, that's 25,500 cd
At 400 L, that's 68,000 cd, and so forth.
Will the TK61 be visible, when (at a cloudy day, at late afternoon) i leave the light alone, pointed at me, and i go at a point away from the light at 200 meters, at low 340 cd, at medium, 26000 cd? at high 68000 cd and what about the visibility of the TK61, when im at 200 meters away from it (pointed at me) at a overcast cloudy day at late afternoon, in spring?
I cannot test this for myself, because of the possibility of the light get stolen, by people.
Maybe get someone to hold it for you? Unless someone has done the same test any answer would be a guess.Will the TK61 be visible, when (at a cloudy day, at late afternoon) i leave the light alone, pointed at me, and i go at a point away from the light at 200 meters, at low 340 cd, at medium, 26000 cd? at high 68000 cd and what about the visibility of the TK61, when im at 200 meters away from it (pointed at me) at a overcast cloudy day at late afternoon, in spring?

So....
Is it just me or is it more than likely Fenix is going to slap an MT-G2 into a "TK61 UE" in the future? Honestly that's what I'm kind of waiting out for. I don't know if the reflector is super optimized for the MT-G emitter but I could see it still throwing like a champ given how ridiculously huge the TK61 reflector is. I was dissapointed when Fenix didn't release the TK61 in a neutral tint. A neutral to warmish even higher output TK61 with somewhat fewer candelas would be perfect for me. I'm guessing the increased max output would help get that beam out close to the same distance anyway. Anyway here's hoping this happens. I know that Armytek Grizzly is coming out soon, right? It has a much smaller reflector though so probably still is going to have a relatively broad beam. If they do this I really hope they keep a high output near 1000 lumens still that doesn't have a thermal step down.
I think Thrunite TN35 is pretty close to your desire here.
