Re: TK61vn V3.5

I dont think theres a way with todays LED technology to get close to a good HID in terms of throw. It would be possible if the MT-G2 was say 10 times smaller then it is right now with the same brightness.
That is why I don't see a point of putting a huge, floody emitter into a throwy reflector.


Name me one hid flashlight that would out throw the tk61vn v3 thats close in size ? must throw more then 700kcd

short arcs don't count

I'm all for TK61vn V3 and its 700kcd+ throw. I just don't like the idea of sticking an MT-G2 in it. It would be a waste of a good reflector.
I also don't like the idea of answering questions asked in an interrogation manner.

the reason is because it would give less tunnel vision and light up a larger area. yes the throw would be cut in half but the area of illumination would be much greater. its not all about numbers. you have to consider how big a given area would get illuminated at far distances.

say we took the tk61v3 and compared it to the tk61v3 if it had an mtg2 in it.

at 300 yards the xml2 would destroy the mtg2 in hotspot intensity lighting up the target brighter but the mtg2 would light up an area say 4 times larger yes with less light but its spread out over a much larger area allowing you to see much more detail at that distance. its more of a practical thrower.

you also have to realize your eyes can only see so far at night

now for me personally im going with the current v3 as it has 700kcd. im a throw junky. p

question not intended in a interrogation manner. you said led technology is no where near hid in terms of throw when clearly led technology or should i say vinh technology out throws most hid lights i know of even the huge thour mods. hid beams are ugly anyway. i never had good luck with them
 
Re: TK61vn V3.5

My TK75vnkt is not far behind the throw of my Polarion PH40. Lumen output seems pretty close. These are observations from practical use.

I understand many don't like the idea of an mtg2 in a tk61. To each their own. But I feel it would hit the sweet spot between lumen output, flood, and throw for more than a few of us:) And for that reason I see nothing wrong with expressing our interest in it to Vinh here in the TK61vn thread.

Reason for what? As to comparing an XML2 and an MT-G2 in the TK61 host both running sizling hot the throw would be cut much more then half with the MT-G2. MT-G2 is so much bigger and has so much less surface brightness then the XML2 that the throw has to be far less then half of the XML2. I'm sure someone can crunch the numbers on that and confirm.

I'd love to see a comparison between my old Firefoxes FF3 40 watt HID (4K lumen, fits in your back jeans pocket) and an MT-G2 in a TK61 host. My guess is the HID would kill it.

I'm a throw junky too with the exception of pencil thin apsherics which I don't like.
By the way...has anyone compared any of the "portable" HID's to Vinh's lights ?

No worries, I was reffering to MT-G2 not LED's in general in my head, I just misswriten it as English is not my primary language.
 
Re: TK61vn V3.5

i had a firefox ff4 for quite while and talk about a wall of light i actually have some beamshots comparing it to some vinh lights

left is ff4 at 60w and right is tn31vn

I am sure that the TK75vnkt would kill my Firefoxes FF3 in throw (it's a much bigger light though) How Vinh gets 4.5K lumen out of that single XML2 is beyond me.
 
Re: TK61vn V3.5

this was a beamshot at my uncles house. left is the ff4 and right is the btu shockervn aka (super shocker)

nothing beats the lumen of the ff4....nothing. i regret selling it but i did because i kept burning my self on the lens after i turned it off. one time i turned if off tossed it on my bed then jumped on my bed 2 minutes later and it bounced up and the lens rested agensted knee and burned me. it just got to hot for me although it it was cool ligth stuff on fire with it

My FF3's lens gets real hot too but I avoid touching it ;) Its 40w so its significantly cooler then the FF4 (smaller though) The FF3 is my absolute favourate light of all time - not exactly edc but small and being able to carry it in the back pocket of my jeans is awesome. The comparison shots you posted are crazy though...the TK31vn is a monster.
Edit: I see you are getting the M25C2vn, dang I envy you man. This looks like the absolute ultimate thrower light to me.

Actually, no, the numbers do not support your claim at all. Take the K40 and K40M as an example, since the host is already offered with both XM-L2 and MT-G2 versions, and will give us a good idea of the rough difference.

The K40 does 95600 candela, according to Supbeam. 618 meters of throw.

The K40M does 65000 candela, according to Acebeam (new name for Supbeam). 509 meters of throw.

So the MT-G2 version has a peak beam intensity of around two-thirds that of the XM-L2 version. And it has over 80% of the throw, while being well over twice as bright.

I've actually argued against the MT-G2 before in the TK61vn, for some of the reasons that koti has mentioned. It is a dedicated thrower, as conceived with XM-L2. But it is by no means a stupid question, and koti's response was out of nowhere...people are allowed to ask questions. I've disagreed with Severus before, too, but on this one I'm with him. It is a perfectly legitimate question, it relates directly to the TK61vn, and he wasn't demanding that Vinh do it, just asking if he has considered it.

As to why the throw is much closer than some might expect, consider that as you increase brightness, throw increases in a linear fashion. So if you double the brightness of a given light, all else equal, you double the beam intensity as well. The MT-G2, then, accomplishes pretty decent throw through brute force, whereas the XM-L2 is a much tighter beam, and accomplishes throw by being very well focused. Either method can work quite well. And each method has different pros and cons. Nothing wrong with stating your preference, but let's not start calling other people's opinions dumb simply because we don't share their particular priorities. Particularly if you are basing your opinions on assumptions, rather than facts.

Ty, you knew I'd show up sooner or later. I love a good argument!

Re: TK61vn V3.5

also if you dedome an mtg2 it has some dam good throw. i saw beamshots comparing the dedomed k40vn to the sr52vn and the throw was the same. the beamshots are in the sr52vn thread. so if the dedomed k40vn gets about 240kcd like the sr52vn put that same dedome mtg2 in a tk61 and im gona guess around 400kcd which is pretty dam good
