TN42vn - Reflector Throw King

[noboneshotdog]

I prefer the $100 savings

Hahahaha. :naughty:

 

[richbuff]

I think I would prefer more lumens with just a little less lux than less lumens and a bit of a bump in lux.

Great numbers though Vinh!

It depends on several factors. How much more lumens and how much less throw.

How much less lumens and how much more throw.

In this case, it looks like the newest Throw King has some more throw and a lot less lumens. So, as I have humbly opined in my previous posts on this ever important question, it would seem like it is too much of a loss of lumens for only so much gain in throw.

But..... but..... What about: What is the light obviously designed for? The light is obviously designed for killer throw, definitely not power lumens. Therefore, in this case, someone looking for a light that is designed for max throw should take a long, hard look at the newer iteration that has some more throw, even if it is significantly less lumens, because that is what the light is obviously designed for.

i dont think you will, matter a fact i know you wont, see a diff between 775klux, and 850 k lux
maybe 2 pictures side by side, if you looked hard, but irl, no way
2400 lumens vs 800 lumens, you will for sure see!
and 830 lumens,... ive got a keychain light , the size of your thumb, that puts out more lumens than that
if it were 1mill lux, then maybe:thumbsup:
if i had money laying around, id probably get spec 4 just to see the difference though
good job mr v, for pushing this to the limit:thumbsup:

Vinh's work looks more like science fiction every day!

oooouuuuaaaaouuuu very powerfull flashlights

New upgraded circuit. Similar upgrade to X45vn circuit.
Upgraded carrier
Upgraded wiring
Beam tune not much different

Are you upgrading the circuit on the other specs too?

Sorry I wasnt clear. The upgraded specs needs DriverVNX2 and the new mod. The XHP35 light already reached its max potential.

 

[search_and_rescue]

Please see below two photos which proved to me XPG2 PDT is very bright; in addition to a perfectly filled hotspot, and high beam intensity. The second photo was taken in daylight!

My next flashlight purchase will be the TN42vn with DriverVNX2 and XPG2 DeDome S4. Thank you guys! Thank you VinhNguyen54!

I had both in hand. The xhp35 hi and the xpg2 version the difference was quite noticable. I am constantly measuring 1 million cd with the xpg2 version so i still thibk vibhs numbers are a bit low but its better to be to low theb to high so its a good number. On a building 100 feet away the difference was clear as day. I love the xpg2 version.

 

[hhmoore]

I'm familiar with the XPG2 beam; but not the XHP35 HI. Is it as narrow a beam, and as tight a hot spot? I still want this light; but waiting has created a new decision.

 

[hhmoore]

Flipped through the thread a bit, and saw some beam shots - the beam looks fairly comparable. Guess my current thought is that for my needs (needs? lol - i have no NEED for this light) Spec 1 will work.
Being honest - my eyes aren't good enough to make use of a light shined over a half mile away at night

 

[eekazum]

just chiming in with my 2 cents.

ultra-throwers like the TN42vn should absolutely NOT be judged by wall-shots that are like 3 meters away. the intensity of the light coming back from that close really just won't make a difference to your eyes. that, and i've said it before and others have said it way before me but "lumens for flooders, lux for throw." heck yeah, i'm curious about what 2400 lumens looks like next to the ~800ish that I have with 7% more throw but you really won't appreciate it unless you have both of them side-by-side and I really don't have the money to get both just to find out. besides, who really uses a thrower for it's spill?

that said tho, I do notice that the hotspot on 500k on my t21vn looks brighter than the huge hotspot on the same 500k on my tn40vn. completely ignoring the lumens, if 2 lights had the same lux figures, the one with the smaller hotspot seems to appear brighter. that, and compared hotspot-on-hotspot, the light that is stationary always seems dimmer than the light that is moving around.

so yeah, to conclude, I got me a tn42vn xpg2 that vinh measured at 900 lumen and 800k lux, and i am seriously thinking of sending it back for an "update" to newer specs even if it's just a measly ~50k bump up

As a general rule, in comparing 2 identical lights with the ONLY difference being the LEDs, xpg2 dedome will always have a tighter hotspot and will always out-throw the xhp35 hi because of its smaller footprint. However, in the same scenario, the xhp35 hi will always have more lumens than the xpg2 dedome.

Also, the modder will have more control over the tint of the xhp35 hi as they come stock in whatever tint is ordered. the xpg2 tends to change tints when dedomed and while Vinh has a great eye for picking out "Preferred" tints, they are not all the same and he goes through several failures as he accumulates his "Preferred" batch.

Lastly, I should probably add that there will NEVER be "2 identical lights with the only difference being the LEDs" because the xpg2 is a 3v emitter (1 li-ion battery) whereas the xhp35 is a 12v emitter (at least 4 li-ion batteries in series).

hope this helps.

the tn40 doesnt put out 500k
its supposed to but it falls short of it
thats why ur t21 looks brighter, it is...

Here is the "problem" with high output throwers, at least in the throw department.

The bright flood, which illuminates everything up close, causes our pupil to close. Then our perceived brightness of the hot spot declines accordingly.

A pure thrower with no spill doesn't cause our pupils to shrink. Therefore, we see the hot spot with dilated pupils, and perceive it to be brighter than a high output thrower with equal throw.

so smart you are sir
very true, very true:thumbsup:
even if the wall of light is as bright, the focused spot will still look brighter

You're right MAD777. The T21vn at 900 lumens and less spill competes ( in the real world) with the XHP35-HI throwers that I have used for exactly this reason. More light on the target, less coming back at your face. [emoji4]

this is why my Acebeam x65 xhp35 hi does not look like it throws 600+ kcd. it looks more like 400 but i need to keep telling my self my eyes are tricking me

have you tested it on your meter yet ?
just curious

 

[brighterthanthesun]

Is the hot spot on the TN42 with the xhp35 a lot wider that the hot spot on the T21 or the TN42 with the xpg2? I assume that it is, but this discussion seems to imply that most of those extra lumens go into the spill.
