Thrunite TN 42 ,a new record in Throw

900k with a XHP35 or with a different LED?

This is what intrigues me the most, seen/read of some of your work with LED’s! :+1:

XPG2 S4 Dedome i think

Well, as you can see from that link some random guy did a lot better than vinh… :stuck_out_tongue:

yeah, guy named alex got one from vinh, and tested the exact same reading that the random guy got, on his meter
who knows, maybe vinhs meter test lower, alexs meter higher, random guys higher, diff batteries , etc, etc….
only way to know would be compare head to head same batteries, same room, meter, same tripod position, etccccc…
i get a kick on how some of you guys on here love to bash vinh, and i think ive got it figured out
hes took his passion, the same one alot of you guys have,turned it into a business, and is probably making a 6 figure income doing it for a living, and it eats you guys up …
haters gonna hate……its a normal human thing for most…. :stuck_out_tongue:

XP-G2? Why? Can’t a de-domed XHP35HD at 2.8amps and countless hours of focusing do up to 900kcd?

Just asking….

How was that bashing vinh…?
Are you just making assumptions or are you oversensitive or what?

He even said so himself that all he cares about is lumens, not lux.

Oh Vinhs a super guy, very personable and talented. That’s what got me into it, Vinh, Richard, Randy Brogden (PFlexPro) I do it for FUN. Vinhs attention to detail and his mods are store bought most times better than factory clean, more power to anybody that can make some coin doing what he loves for a living!!! :wink: :+1:

Oh no you didn’t. :smiley: Hmm…well I’m going to give it my best and we will just see where the chips fall.

I’m a little confused by the numbers he is quoting for that XPG2 light. Given what he quotes for the XHP35 lights it would seem either poor integration or he is holding back. I can of course get higher throw numbers by going to a smaller die but I really think people want a no sacrifice light and that is what I am aiming to deliver. By my calculations 1mill is reachable with the XHP35. I’m not quite there yet but close. Looking for massive thermal improvements. The one major thing I’m trying to solve is the weak bond wires.

:+1:

1.2 mil , out of a xp35, at 2600 lumens would be sweet
id like mine delivered first of next week if possible ! :stuck_out_tongue: :smiley:

I have an XHP-35 doing 3.11A and making 2869 lumens, but it’s in a smaller reflectored light and doesn’t do the big throw numbers. Point is, the emitter can take quite a lot and put out some lumens, getting it in the right reflector with the right focus is the trick, and of course, keeping it cool. :wink:

damn! guess how far my TN42NW reached? looks like Thrunite is really really understating their numbers! It does way more than just a mile, and this in a light-polluted area

After having over 12 TN42’s go thru my hands and I personally own 4 of them 3 modded and 1 still stock, the one thing I can say is there are gains to be (possibly) had just by floating the mcpcb board into the reflector. Plenty of clearance between the boards clearance holes and mounting screws. :wink: There is also clearance/slop between the centering ring and the ID of the reflector, then you have the variance between the thickness of the centering ring itself.

Now take into account the actual mounting surface and the mcpcb surface, is the mounting surface flat, no burrs sticking up and around the mounting holes, the wire access pass thru holes? How about the mcpcb is it flat and burr free? LED perfectly flowed on , flat, square, centered? These are production lights, with possible human assembly and machining flaws/ errors? With reflectors this big, every little bit can help or hurt LUX readings!

There are gains to be had with a little bit of finish prepping! :wink: Add a resistor, swap the driver 2.8-3amps, reflow a higher bin E4-HI or de-dome E4-HD emitter on the board for even more!

how do you check the amp draw on this light ?

At the emitter, the only true way of knowing (for me) with a boost linear or buck driver. I checked it with a Fluke 36 and the Uni-T clamp meter.

All this seems pretty advanced for a newbie like me. But what i do remember from reading many posts is that most people have had their XHP35HI’s fry short of 3 amps. How is it that they may be able to handle this current, or 3.11A like DB custom got?

How many more lumens can i get from dedoming the HD version, and would you happen to know what bin of the stock LED?

Lastly, how far have your modded TN42’s hit? Any chance of 3km? If so, i’ll never want another flashlight other than this one!

Here is some info… XHP35 output and death test + PWM efficiency test by Texas_Ace

Ipopped a couple of the earlier lower binned XHP35’s but the E2 and E4 binned seem to be able to take an occasional 4+ amp burst but I think out put wise top out at 2.7-2.8 amps. I have been running all 8 different XHP35 E4 and a E2 builds 1 at 2.5 and the rest 2.8to 3+ amps and only popped 1 using a early RMM Buck driver, suspect voltage/current ripple, replaced the emitter and it’s still running fine so far. I have been running RMM’s e-switch 4S Buck drivers and Neven’s 4S LD-2 M2 Linear drivers. and using the K70 4S battery carriers.

Any of these emitters can be or are fragile up close to their peaks, so some current ripple or spikes at turn on can be damaging. This is where a quality driver makes the difference. I usually use Neven’s LD2 with the proper components for 4 series cells. The last one I built that’s doing 2.42A is a Buck driver from Richard that I asked him to set that way.

Fine tuning by hand with careful attention to detail is what makes the difference for most hot rodded lights.

So the stock TN42 driver would preferably be swapped out with an LD2 or the RMM buck driver? I’ll probably be needing a K70 battery carrier in that case?
