Thrunite TN 42 ,a new record in Throw

I agree.

An XPL HI would perform great in a large reflector light. Of course we know that; people here make big XPL HI throwers all the time. The XHP35 does have advantages over the XPL HI: similar luminance but with potentially 50% more lumens. This manifests itself as a hotspot with similar intensity but with a 25% bigger diameter (XHP35 active area is ~2.50mm while the XPL HI is 2.0mm). This is nice but not a huge increase. And it comes with the complication of being 12V. It’s fine that manufacturers use the XHP35 to get that 50% boost in lumens, but we modders can get a pretty similar result with the XPL HI much easier just using a FET driver. Though of course I wouldn’t blame modders for wanting the XHP35; it’s all about optimizing the performance.

Yeah, it would be nice if there was a single cell driver for it that would push it further than 1.5a.

But you would loose runtime and/or runtime on max setting .

Well, isn’t it always a compromise between brightness and runtime?

Yeah, there wouldn’t be much runtime on one cell…just dreaming I guess, lol.

Dreaming isn’t a bad thing :beer:

Has been on holiday for last week, and today got my TN42 from my work place.
Below are some numbers for ref.:
Flashlight - Ceiling Bound - Lux @ 7.5m (kcd) - Total weight with batteries
TN42 (NW) - 286 - 9440 (531) - 852.7 g
K70 stock - 328 lux - 7580 (426) - 772.9 g
K70 (NW) - 323 lux - 7440 (419) - 773 g
TK61 Mod - 189 lux - 7170 (403) - 790.6 g
BOSS1 Mod - 196 lux - 7130 (401) - 1492.1 g
Maxtoch 2X - 199 lux - 4530 (255) - 412.8 g
TM36 Lite - 161 lux - 3410 (192) - 1066.9 g

(Remarks: The TM36 Lite is under performing using protected batteries in parallel. The intensity test may not be as accurate as the distance is too short)

Here they come :slight_smile:
Below are the beam shots at about 110m distance, taken using Canon EOS 70D with 15-85 IS USM using tripod:

Great shots, thanks for the test!

Poor neighbors, did they called the police or anything? :stuck_out_tongue:

I am not sure, that’s 3:00 am. During the shooting, there were some lights being switch on and off. The area I shined at is the corridor, but the beam coronas spilled over to their kitchens (left units) and bed rooms (right units) :confounded:

Awesome pics wkhchin81, I am surprised that the Boss 1 was able to keep up and has a smaller corona. what kind of mod did you do on it?

BLF A6 DD driver with XPL-HI V3 1C from Kaidomain, the copper based plate is from Noctigon 20mm XP, with bypassed spring and a copper ring attached to the original driver for anode. It measured at 1400 lm when the batteries are fully charged. During this test it was about 1300lm. I learned from TOM E :+1:

I got over 700 kcd on the BOSS1 (forgot but maybe tops was ~740) with a dedomed XPL. Should hit 800+ kcd on the hot XP-G2 S4 2B, which I still have a couple of, but didn't try in the BOSS1. Tuning is the key, and I didn't get to locking the tuning down to the max throw setup. It's tricky to test over 10 meters for me as well, but you really need to go over 10 meters to get an accurate measurement on throw. My convention, and Dale's, is to measure at 5 meters - I can do this by myself, day or night in the basement.

For the outdoor tests I did at over 10 meters, think every light I measured had a higher reading.

The 4 big low resistance cells I used (EFEST 4200's) really help battle the Vf. Amps goes up with each added cell, in fact I blew a dedomed XM-L2 U4 1C in the BOSS1 from too much current, and the dedomed XPL seems to hold up to high amps better.

Of course the TN42 is a different power system of 2S2P, probably has a superior reflector to the BOSS1. I'd love to see a dedomed XPL/buck driver setup in that light - could probably get 800 kcd out of it, specially with a higher bin XPL of W2/W3 class. Of course the TN42 is an expensive piece to buy as a host, and don't think RMM's buck driver works well, if at all, with an e-switch.

The BOSS1 is typical budget quality all the way, just up-scaled in size. Wish they would start dumping them at a $40-$50 price, then I would definitely buy a couple.

How many Lumens had the Deft-X?

anyone pumped up the TN42 yet?

i ordered the NW one and hope that 2.5 - 2.7 A would work...

Yeah Tom RMM’s Mtn.Max 4S E-switch drivers work, the SD75 with the smooth reflector on the right, is running one with a 3amp choked down to 2.81+ XHP35 beats my K70 for throw.

Early driver TEST VICTIMS……popped a few 35HI’s and 35HD’s too!

Not sure I understand... There's no e-switch firmware option I could see: http://www.mtnelectronics.com MTN-MAX 26mm, and if you do set it up, what's the parasitic drain? I thought that was the big issue?

I asked, he made it? I got it in the SD75 and the T90-2 too…

XHP35 Gang….The L6 is running one of the smooth test reflectors I got from Simon now, Old pics from this summer, built a couple more since then…K70 sits in a BOX in the closet… :smiley: I have 2 TN42’s CW/NW sitting at home, see whats up with them, the other T90-2 Linear driver, I built is waiting on a show down! :+1:

I think it had 450 lumens.

I believe you - don't need pics of an invoice or lights. I'm curious because he doesn't advertise it, and I thought parasitic drain would be an issue - thought he mentioned something bout it before. Ok, guess Richard didn't mention anything about the parasitic drain to you and you didn't measure it. Oh well...

Ahh - found the post from Richard: https://budgetlightforum.com/t/-/32835/63

I think the parasitic drain is a problem with the zener mod. By using a linear voltage regulator it looks like that problem is solved. Like here:
