They added now the Short Body and Battery 
*I sent my copper E07 back to Jacky in the US address for fixing because 3 things were broken and wrong and I am still being ghosted by him. I repeatedly messaged and emailed FF and Jacky, and always got ghosted. 2 years at this point and over $100 down the toilet. DON'T BUY FIREFLIES OR ANY OF THEIR NEW BRAND THEY ARE A BAD COMPANY. Do not do business with them. Buy from better people and companies.
I ordered a mule on 20/03/2021.
I received a shipping notice on 01/04/2021
Still waiting, no communication, the tracking number is not working 
I’m starting to regret not having taken a D4V2 mule
Jack was out of town. He just got back to me today so he should be getting to your emails soon. I can imagine he has thousands of emails to go through. But don’t worry he always takes cares of things. Just takes a while sometimes.
My tracking didn’t work until it was in my town two days ago (USA), it seem they are shipping like BG does.
Ordered lots of times, it eventually gets there
I ordered the Short Body ect ….19.03 and got an Email from Oliver that they Shipping my Order ASAP
Now we have 10.04 and nothing happened.
I opened a Paypal Case now………but still no Communication
………Ok Jack was out of Town. But do you run such a company?
Even if you don’t do it full-time, you still have an obligation to the customer.
I mean the Nov Mu is really great and Top Notch Quality.
But it will ruin the business in the future when he not changed his Support and Communication.
Please do no business with this company… clearly they dont care just ignore and dont even bothers reply to emails… buyer beware
We don’t like slow emails or seeming lack of parts sales, but they are offering something no one else is.
Many (if not all) hank lights are using inefficient linear driver, and the mule design isn’t as good as NOV-MU (mules should be centered LEDs).
Still nothing heard from Fireflies……… nearly 1 Month and no Shipping…Tracking or anything….
Does anyone have contact with Jack and can they ask when he can finally start sending orders again?
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 
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
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?
