Using a 20mm board should be fine but you will have to center it proper your self. You could always drill and tap new screw holes if you wanted. The reflector base is fairly big ill check clearance now. Okay so the reflector hole is huge lol if you use the stock gasket it fits all the way around a 20mm board so that will act as electrical isolation
Gasket size is 23mm overall
Reflector is 62mm (outer ) Looks almost 60mm inner
Bottom opening in reflector is 18mm
MCPCB is 28mm
Lens is 65mm
Driver 30mm
How did you get it to fit? The 28 mm barely clears the solder pads. What are the exact throw #'s? My 2nd NW does about 230 kcd, my 1st one after the mods actually seemed to drop throw to 238 kcd. I'm not too surprised because any fiddling with LED/MCPCB, etc. can change things slightly, enough to make a difference. The modded one though has a better centered beam pattern.
Well I blew up that de-domed emitter. Must have nicked a bond wire. I had to reflow it from the 20mm over to the 28mm; still had to cut the gasket because I obviously can’t solder well. Light went white, then blue, then purple, then nothing.
Oops! Lessons learned. Although I’ll most likely need to try and get another gasket somehow, sigh.

-LED seems perfectly centered
-Bezel and Body NOT GLUED
-AR Coated Lens
-I disabled step down. Popping/clicking noise started after 1 minute of turbo.It was sporadic and Not too annoying. More than 5 minutes after turning off to rest, still making popping noises!,a few per minute!
Ran on turbo for 10 minutes/tail stand/no fan/Loft Temperature was 68F/20C. I was able to easily hold handle of light after 10 minutes of Turbo. NO RED HAND EITHER!
I look forward to using it tonight. So far I am pleased w/Lens/LED centered and NO glue!
Next is Turbo run time test. After this I know my light and batteries Very well.
When I can run MAX output tail standing on my loft for 10 minutes,I easily surpass that[usually double] on the trail,regardless of which light it is. :+1:
I will be doing my Turbo run time tests w/ my Brand new.
The 26mm fit no problems, had to mind how I ran the wires to the pads but nothing special to get it together and to clear the reflector.
My <10 year old meter reads low so the numbers themselves are for direct comparison only…
Stock NW = 198KCD
SST20 NW = 248,400Cd
For consistency readings were taken with the same cell fresh off the charger for each test.
On topic, this was the worst maxtoch mcpcb I’ve ever received! Its back side was more wood grain like than the stock one was, had to spend 20min with it getting it lapped smooth. There was actually a lip around the entire edge of the thing that prevented 99% of it from touching before hand!
Are those measured voltages DURING the test or did you have to shut the light down, remove the cell and then test?
HKJ has shown how inaccurate that method is. Voltage recovers in under a second or less… To get the 30min run-time readong of 3.59v the cell was likely actually at or below ~3.2v during the test (unless you were measuring cell voltage during).
Are you sure you measured the 10 minutes in turbo? ramping to the top is not turbo. It is about half output of turbo. No way it was run 10 minutes without stepdown and 2020C temperature after 10 min turbo. Something doesn’t right. Mine was 52C after 4 minutes. then it stepped down. If you run it to the 10 minute mark maybe it cooled back down.
Ok,just did another simple test. Put my sun glasses on and went in the bath room!!! White Tile and white walls,very bright w/ FT03 TURBO on.
Double click to TURBO and held light in hand for 10 minutes,now ROOM temperature is 70F/21.1C.
After 4 minutes, yes, the LED/Neck/Switch area is starting to get hot,I do not hold the light there.
After 8 minutes the handle is starting to get hot,no biggie for me as you can see in the picture below from another much more powerful light[TN42vn 90] last summer.I hold the FT03 for 2 more minutes[10 total].
Twice during the test I quickly turned on and off[5 min. mark and 9 min. mark] to see ramp MAX output,back up to turbo was clearly noticeably brighter. Again, I do not know what the output is after 10 min. consecutive turbo,but it is clearly and so easy to tell that it is MUCH brighter than MAX ramp output, even after 10 minutes of turbo.
Your dealing w/ a turbo freak who is not afraid of a little pain!
Just a reminder,PHOTO below is NOT from today,i have posted before. 20 minutes later when I got home after LONG turbo runs w/ TN42vn90 in the summer time.
