On the Noctigon K1 w/SBT90.2, after spring bypasses I got 5410 at turn on with a 30T, 22.3 amps measured. The bypasses gave it a nice bump, up from 4850.
On a GT90, kit modified, I estimated about 5600 lumens. I can't fit the GT90's head in my lumens tube, so did some comparative tests off of the glass, and approximated the GT90's reading.
Wow, Tom, these readings are very exciting and just further my hopefulness for this light. I really like to see the lumens staying so stable over the first 5 minutes, and also with the weight coming in at under 800 grams. I’ve been playing with my new mf02sv2 this week, so this wt90 will be a blast! Also, Narsil will be nice as the mf02sv2 likes to step down a little, nothing to complain about, but the Narsil in the wt90 is, besides lumen longevity and THROW obviously, one of the things I’m looking forward to the most. Speaking of throw, 950kcd, hell ya! Also that is pretty damn close to what you estimated a week ago iirc 
Yea, agree, I'm lik'n it. The weight reminds me of the old Fenix TK75, though never bought one, I worked on 1 or 2. Also the #'s are impressive without mods. Did test on the 40T and got slightly better #'s, but didn't do more than 30 secs. I'd expect the 40T to drop quicker as well.
I think adding spring bypasses would get a decent bump - saw a big bump with the HK90.
Very nice numbers as is! Are you going to/allowed to mod the prototype at all? Would be very interesting to see what bypassing the FET that’s in the carrier would do!
yea that is good info! I hope the 40T doesnt fade too bad, i just ordered some for this light LOL. i would buy Vapcell’s, but are they available anywhere? this may be the first light i try spring byass on, or maybe the K1 first while i wait for the wt90. What gauge wire did you say you used (for the K1)? I have 18g and 22g, but ill order some if need be.
EDIT - I just found it - looks like 20g? for the HK90, on the springs?
Think TA said ok, but will double check before doing anything. Only issue I'd see is with higher performance cells, might make the option to "run turbo til the batteries drain" little more heated. But I betta with 10-15A rated 5000 mAh cells, should still do turbo continuously.
Only way to calibrate a lumen tube is with a calibrated light. I have tried every other method, they just don’t work. Get a light from maukka if you can.
Yep, I gave him the ok, preferably keep it working but not real worried about it lol.
Very nice numbers Tom. I now am wondering how long it has been since I cleaned out my tube, it gets dusty and the numbers drop over time….
Interested for Ano version
can. no. longer. resist. Interested in clear ano
Wise choice! [quote=Texas_Ace] The prototype is officially in the mail on the way to TomE for a more in depth review with beamshots! [/quote]
Seeing this come in right around 1Mcd and considering the relatively low weight for its size makes this a tempting light. I gotta be honest, the styling just isn’t doing it for me… I’ve tried to let it grow on me too, but no luck. I liked the styling seen in the early part of the video, and think the ‘zebra’ prototype looks best out of the final designs.
I’m very curious to see a thermal analysis and to see what happens with the rpp fets and springs bypassed. I have a FLIR camera I wish I could lend out to TomE to take a timelapse series.
I mean i wouldnt want to get involved :innocent: but that sounds like a great idea ! lol
Damn, its only been a week since this Thread started?? I want to order this light! TA, where are they at? 
I think spring bypasses will help. There's one on the driver and 3 in the carrier. Using cells like the 40T with the spring bypasses, the heat may get out of control in a few minutes. Also TA noted the LED wiring is different in this prototype - uses a thicker gage pair, while in production, they are using 2 pair of thinner wire for better clearance at the solder joints with the reflector.
Hoping this evening I'll get back to it and do/start the mods. Ideally with the bypasses, you could still do a full turbo run (cell drain) with lower performing cells like the Samsung 50G's. Only thing I've done so far is add light amounts of Nyogel on the threads. I've been side tracked with the EA02 - not a light for the masses, being a Boost HX with FET+1 driver, plus they made the battery tube slightly too narrow to fit some cells, and a little involved than most to tear down 
.
Huh, so bypassing springs and running high all will effect heat that much? Good to know. And honestly I am really happy / impressed with the stock numbers, I probably won’t even touch or mod this light then. I’d rather have a almost 1million CD 4500-ish lumen light that can run for 5-8 minutes not melting than picking up a 1,000 lumens and dealing with the heat. Just me. I’m sure many would rather hot rod it, but this will be a beast anyway.
Well, I dunno yet for sure, but speculating it will. I agree - stock it's pretty darn good for it's size/weight. The smaller new MF02S (SBT90.2) is 62g heavier.
For me, I'd rather tweak it for best performance with high performance cells because I'd guess you could still get 3 minutes comfortably, and you can always drop down the amps by using lower performance cells with higher capacity.
That’s a great point, so the mods and run lower amp cells or just back off turbo a little sooner. But you still get the lumens. I like it
there is also the option of simply not putting to full turbo unless needed if you are worried about the heat. Fact is that top of the ramp is enough for 98% of real world tasks and will easily keep heat in check.
Tom, I am betting even with high drain cells and bypasses that the light itself will be fine, the cells on the other hand you will want to keep an eye on, they could get a bit warm. In my test they were 75c when I pulled them. Although higher drain cells have lower IR, so they produce less heat themselves but that could be balanced out by the higher temps of the light. So hard to know till it is tried.
