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
Below are the beam shots at about 110m distance, taken using Canon EOS 70D with 15-85 IS USM using tripod:
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:
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.
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… 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 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...
thats a mean looking group you got there. very surprising that your sd75 outthrows a k70.
so the t90 throws the best of the bunch? have you done the showdown with your new tn42’s yet? curious to see how they stack up
This is well known - the LDO is for e-switches, the zener is for power switches. Zeners have significant drain, LDO's do not. We are talking bout the MTN-MAX buck driver, different animal - this is what he referred to, and buck drivers are a more complex design - some can have high parasitic drain, some are very low if they are designed for e-switch lights properly. You linked to a straight simple FET based driver.
Got my TN42 NW today. The PWM (if it actually uses it) is totally a non issue, since it cannot be seen with the naked eye on moon. Have to check with the scope later.
And yes, I also got 700kcd. Measured with a cheap meter from 3.3m so will have to check again but still.
I have been using flat top Samsung 30Q’s in my TN42, they are a little loose so I ordered 4 LG MJ1 button tops for the 3500mAh capacity and 10A continuous delivery. I found some weird action in charging them up, they didn’t all charge initially and when I did tinker with them and get them charging they terminated early at around 4.17-4.18V. Never had issues with 4 new cells before.
Just tested the big light on the meter and it showed 700Kcd exactly. A little lower than the 30Q’s at 702.5Kcd. I’ll try to drain these MJ1’s a bit and do another charge run, see what they do.
