I know for sure that my convoy L6 can stay on turbo indefinitely, it doesn’t get that warm….
For that reason I decide to order SST40 variant of Nightwatch with 5k lumens because want turbo for longer times and its have better heat dissipation design compared to FW21Pro.
I have a stock FW21 Pro. Does anyone know what the color temp is with the XHP50.2 emitters in this? 5000k? Or 6500k?
The color temp is ok for me, but my only quibble with the XHP50.2 is the green corona around the hotspot is a little irksome, though it isn’t terribly bothersome - generally only noticeable when white wall hunting. But I do appreciate minor improvements, when I can get them.
Is there another emitter option, to mod this light with, to get rid of the green corona, but still retain reasonably high, cool white, lumen levels? Would XP-L emitters work well in place of the XHP50.2 emitters?
I don’t care if I can’t hit 10,000 lumens on turbo. For the most part, I would use the light within the ramp range, only using turbo very briefly on occasion.
Probably 6500K is original FW21Pro emitters. 5000K version of XHP50.2 are difficult to find and manufactured only by special order. Good replacement for XHP50.2 is SST40.
why not XHP70.2 ? they exist in neutral and warm white tints…
I’ve read that the SST40 has a greenish tint shift at med to low levels?
Good question! Do these have a greenish corona around the central beam, as the XHP50.2 does?
If not, I’m sure I’d be thrilled with moving to XHP70.2 in neutral tint.
No idea, i dont own any light with that emitter sadly… but i just placed order for the FW21 from neals… need this light haha 
What is the best battery for this light (NightwatchNSX3) for Max output? Samsung 30t? 40t? Button top, flat top, both?
I have a sofirn 21700 40a
and an ijoy 20700 40a
I don’t know if they are enough to do the job. Thanks for the input!
Max output bar none: Samsung 30T
Best all around 21700: Molicel P42a and/or Samsung 40T
I have 2 molicells and 2 40Ts.
I’ll see if I can do a full charge output test
I don’t think the type of top matters unless you arent getting contact…
do you have a suggestion on where to buy in the states
Thank you!
Is there any harm is trying the ijoy or the sofirn? They are both rated at 40 max amps
Link to ijoy I have
I appreciate your help!
No harm, you might not even be able to “see” the difference.
40 amps is plenty - IF you can trust the rating.
I just didn’t know if there was any chance of harming the battery or light I’m still noob
This is incorrect. Those are fake rating and usually top out at 15 amps or so
Well damn, I guess it Samsung 40T time
40T is the best battery if u want decent runtimes and plenty of amps to run this kind of lights.
Ok I just tested my fully charged 40T against one of my Molicell P42a in my FW21 Pro (turbo of course).
My homemade lux meter box results (highest @ turn on using):
P42a: ~16,600 lux
40T: ~13,800 lux
(Note that these results are relative to me only)
I am not able to detect a visual difference in regular usage (dark room or outside), but the difference is measurable with a meter.
I’ve decided to reserve my Molicells for my FW21 Pro and use the 40Ts when I get my E07.
