Fireflies NOV-MU 21*Nichia E21A mule 1x21700 Flashlight --in stock

I ordered an E07x on the 18th of March, got an acknowledgement email two days later. I chased on the 5th of April but heard nothing back. I know Fireflies communication is very poor but at this point I don’t know if my order has been despatched or is delayed until the next production run. They only had 120 pieces so that’s only 120 emails to send out….

dealer on reddit says “they will be shipped this week”

but this week ends tomorrow

They were pretty late with NOV-MU.

I received my mule :smiley:

Nice product well finished; the absence of optics is much more pleasant indoors than my D4V2 E21 2000K (not a mule).

And the magnet is super strong !

Total delays: a little less than a month in all to France.

I hope so

Hey guys,

Took a quick look and didnt see much discussion on batteries for this light. I just ordered 3@novmule and want to get some fresh cells. FF has the 40t as an accessory so i guess, thats their pick or one they have on hand that works. Any opinions on cell? I have samsung 40t, 50e, 30t, and molicell p42a on hand. That said, would like to get fresh cells.

Arguments for or against any and all is appreciated. For ff: nov-mu 4500k

Use case is variable, so i am leaning towards 50e. As turbo isnt really the goal. I prefer full flood for the work i do, (closeup <10’). And turbo doesnt make sense for that. Balance of runtime vs max lumen, i would pick runtime—that said, i suppose i need something that can hold low-mid output to high output (not turbo) for the longest time. But, some vaper blogs suggest with high draws the 40t lasts longer than 50e. Maybe i misread it. Was some time ago.

I read somewhere while researching this light that it can run off charger while charging but draw cannot exceed charge input. I.e. it doesnt work as a power cord, it runs off battery [stop] battery charges [stop]. Independently. The recommendation is while plugged in to not use at high levels. Kind of a sad little bottleneck, but is what it is.

So, to sum up. 1. Battery thoughts, 2. Workaround to run off charger at higher levels.

Thanks

The Vapcell T50 would be my choice, but it would be my choice for just about any 21700 light.

Yep me too Vapcell T50 is my choice for every 21700 light right now.

Anybody else experiment with aspheric lenses for their nov-mu? This person fitted an aspheric lens on his, and got a little more focus out of it without much sacrifice to beam uniformity it looks like.

I just ordered a 4500k nov-mu, and also ordered one of those aspheric lenses to play around with.

Don’t bother, it hardly has an effect. It’s too close to the LED, won’t fit right, lose water/dustproofnes, etc. I couldn’t even tell the difference.

This is the one you want. https://www.aliexpress.com/item/1005001632207307.html

Get a few of the 29mm since they’re plastic so easier to scratch. The fit is perfect, the result is a bit more focused beam but the tint-shift is more prominent.

So 29mm over 28mm?

Yes. I got a whole bunch of them and the 29mm fits best.

Tom, skv
Thanks.

The vap t50/ sam 50s is a unicorn. I agree with your assessment, but it would arrive middle july—maybe. And 25$ not clear on whether that is 1 cell or a pair. Impressive battery. But, cost benefit analysis + arrival date makes it something i will look into later. Been awhile since i shopped batteries. Looks like molicell m50a or samsung edging a hair with the the 50g. (Per mooch) lights are ~2 weeks out. I cannot imagine t50/50s showing up available before then. Sooo, probably put that on the want list and grab some 50g’s.

Will get the unicorn when it makes its way to illumn/imr/liion. Unless you can point me to another reputable shop stateside that carries them.

Thanks for the input.

Followup: are you aware of an amp ceiling for this light. I mean can
i put a 30t in it or will that kill it?

I no longer work in the field so it occurs to me it is not very complicated for me to have spare cells on the bench and swap out as needed. Been doing this for awhile. Not nearly as bad as having a holster with 4 cells in it pulling your britches down.

So, having a sense of recommended upper limit might have me go in a slightly different direction, i.e. 30t, p42a. I dunno. Seems like once every other year i upgrade lights and have to go thru cost bennys on cells all over again.

Thanks.

Oh, and back to use case. The lights would be in 70°f, constant on. So whatever that spot is where it all settles down might probably be where i want them. Ff site claims ~1100lumen for a ~3hours. Also a thermal step down point. So i suspect will be aiming for best way to stretch 1100 lumens over time. T50/50s unicorn best, but still a unicorn. Any thoughts on usa available cells?

30T will not harm the 21 E21A emitters.

You did measure a lower intensity using a 30T which shows the E21As are probably in the point of diminishing returns at such a high voltage. I’d recommend a 40T or less powerful.

The output with the 30T is slightly higher but it’s not worth the loss in runtime.

Sorry, I misremembered :person_facepalming: You’re right, and the difference probably wouldn’t be noticeable to users’ eyes.

Finally i got my Trackingnumber from Jack :+1:

Today I received a flashlight ordered in December. Longest shipping in my shopping expirience)

But it seems to be broken . From 25% output and higher it flickering and buzzes. Or is it normal work of this Lume driver?
