Goncz Titanium Knife / Flashlights

"Pardon my ignorance, being merely a "knifnut" (Honest, a dozen flashlights is not too many. You never know.), but I am confused about "600 lumen at 5500 Kelvin!!!" (Post by Mr. Goncz on 11-27-03). I thought Kelvin was a temperature scale starting at Absolute Zero. In that sense, 5500 Kelvin would be, more or less, +4730 C, and that's pretty hot, yes?"


Read here to learn about color temperature:

In short, the color of North American midday Springtime sunlight is around 5,400 Kelvin; so he is telling you that the flashlight puts out light which looks like the same color as sunlight.

Kiessling,

as you said the V2T on three /maybe/ fresh 123's did 216 lumen. specced max lumen for a v2t (and you know charlie dont use junk emitters) is 148lumen. At 1.5A a 5w should produce 140% of specced lumen on a hotlips heatsink (from a relative lux test that someone did), which is AFAIK one of the best existing for flashlights. I think a T bin might pull about 1.8A from fresh 123's.

Drawing from these meagre data I should guess that the SNII optical setup (mag C reflector and UCL lens) is very efficient, i suspect more than 85-90% is coming out the front end.

As to goncz claim of 150lumen, I don't know anything about that (what setup, 2x123 and 5w?), but I am pretty confident the bb750*X3T with pelican reflector is more than 150lm.
Driving a 5w beyond that (750mA) is possible with 2x123 (the bb750 pulls only about 1.2A) but I think more space is needed than a pr adapter.
 
GEB / LED

The diodes are not placed into a PR base. They are mounted into a module that is exchangeable and direct in contact with the flashlight whole body, thereby the heat is prety much absorbed.

The informative Thread!!!!
 
Goncz, as far as I can tell the Carley pr base that I have is plastic in a steel can. I'm not sure on this however, will check on it later.

What I ment is that Carley can factory pot bulbs (like Welch Allyn bi-pins) in a pr base with ceramic. the bulb will then be stuck rigidly in the base, so as not to become unfocused. Also the potted bulbs can tolerate more heat than the PR bases they sell. I don't know if this is an issue for you though, I am driving a WA01274 (2.77A, 7.2V) bulb with four 123's in a mag 3c with the adapter and have seen no damage. I don't know what actual voltage and current it sees though, since I'm fresh out of fresh batteries... :(
 
:D - actually Gonzo is using the same bulb but driven with 3 123 cells and therefore heavily underdriven - and not potted but using the standard Carley plastic PR base - so one more time some heavy bending of the truth here - claiming its ceramic and shipping plastic parts :grumpy:

So besides the inflated brightness claims (does that even make you wonder anymore when he´s claiming the Kelvin color temperature is "indication of the brightnees of the light" :rolleyes: ) we also have the claims of Borofloat lenses while shipping plastic and claims of ceramic PR bases while shipping plastic - thankfully the flashlight body really was aluminum as advertised :D

hey, in goncz defense he never advertised borofloat lenses. they are boroflo lenses :p

*edit* typo corrected, bad fingers! :twak:

I guess you didn't notice the smilies used... Too subtle for you? :p

Actually, I would be highly surprized if you would honour the promise you made... ;) :eek:

btw, you seem to be more familiar with screwing people, so I'll leave the canal district for you. ;)

LOL at Roth,

its none of those you or Gonzo use actually - I might sound like drumming my chest but the stuff Gonzo claimed to be using is named BOROFLOAT by the german company Schott who is producing it - so I stay with that name for now :D

Borrowed from flashlightlense:

Materials:

Borofloat®: One of the materials we use is high quality Schott Borofloat® glass. Borofloat®, and its Corning equivalent Pyrex®, are both forms of borosilicate glass. They both have an excellent ability to withstand thermal shock. The difference lies in how they are formed. Pyrex® is usually either drawn or cast, whereas Borofloat® is formed using a special float process. This results in a glass with better optical quality. For more information on Borofloat® glass visit the Schott Website

@ ailsnail

reading some posts earlier in this thread you´ll find a post named "M3 de-mystified" in which I do some measurements of the M3 with the supposedly stock WA 01274 bulb using 3 x 123 and 2 x 18500 cells. That the M3 will fit the larger 18mm cells and that 2 of those 1400ma 18500 Li-Ions are much better able to handle the bulbs current draw I posted about a while ago already - actually with two of those cells the light really starts to make sense somewhat.

bah, that stoopid quote quoted my message before i edited it :mad:

yes, i know what he meant, but he just couldn't seem to spell it right :D
one time it was boroflow, one time it was boroflo, one time it was boroflaw, who can keep up? :D

i've got a borofloat lens in one of my mag mods...very nice lens! :D
 
Mr. Goncz, is the Goncz Titanium Knife coated with TiN at Rc 72 or is it a titanium knife hardened to Rc 72? Is the hardening differential? Can you link to a picture? Are you still producing them? Sorry for so many questions.
 
John, I have been unable to find the Blade article that you have mentioned a few times in this thread. In an earlier post you stated that is I couldn't find this article you would dig it up and email it to me. I have sent you an email requesting you do this for me. I thought I would also bring it to your attention here. Thanks.
 
ailsnail,

I, too, am thinking very highly of our BB750/X3T/PR combos, and my personal impression is that those might very well put out more than 150lm, but McGizmo himself expressed some doubts ... but then again, he is a rather modest and understating fellow. One of our best.

My real point here is that when looking at the sophistication of this tool and the incredible wisdom implemented, I have my doubts that John will be able to create something remotely similar. I am drawing those conclusions on the knowledge of the GM3, the only Goncz light I owned.
I am always open for a redefinition of my thoughts though ...
:)

GEEE, is advancement even a romanian commie agrees that we are using better lenses than surefire. WHAAAOOOO this progress.

Soon will be discovered, that We have the best focusing system, known as : GONCZ THREADLESS FOCUSING SYSTEM in the world.

Other "smart a.." will discover that the lights do hold up to the claimed waterproof for 120 feet. (Ed already tested for free for 180 feet and the light is still works)!!!

Soon some others, smart will recognize that we are building the best lights in the World..

As I stated before soon The Goncz Hi-Tech lights are for the profesionals that already using it and will grow and grow. The "six pack Joes" will carry the other lights.

The informative Thread!!!
 
Heck g.b....don't be so hard on yourself. You don't need to allege that your from Romania to get sympathy. You can stand up and claim Slovak heritage!!

Hold your head up...you are starting to get some degree of impartial pats on the back here. And after all, isn't that what it's all about? People helping people? :D

Stuart
 
For anyone interested, check my post on page 23 of this thread that documents all the various waterproof claims Mr. Goncz here makes. We've dropped in incrememnts from 500 feet to 120. Either the lights are getting crappier as time goes on, or the actual true number are coming out(or both, which wouldn't surprise me)

And Goncz, if you could read, he didn't say you used anything better than Surefire, he said you CLAIMED to.

BUt considering experiences of people who've used your lights and had a lens melt, I find it rather doubtful.
