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

Rayoui beat me to it! I was going to say that the text-based manual describes that as such:

Lockout mode also doubles as a momentary moon mode, so the user can do 
quick tasks without having to unlock the light.  The brightness in 
lockout mode has two levels:

  - 1H: Light up at the lowest floor level.

  - 2H: Light up at the highest floor level.
        (or the manual mem level, if there is one)

Gosh...I was way too late. :-D

You can set different floor levels both for stepped and smooth ramping, i.e. you can program a higher floor level for either one of these mode groups. 2H from Lockout mode will use the higher floor level whereas 1H always uses the lowest possible floor level.

Thanks guys. I will give this a try. I have it currently set on hybrid memory and still getting the same output. Will try manual memory and see if it works.

I measured way over 5200 lumens for the 4500K but 40T got me more power than a 30T, are the LED’s gonna turn blue soon!

Ohh… so when you originally said “no where near the claimed 5200 lumens” did you mean that you measured higher? Usually saying that implies that you measured lower.

That’s what I thought he meant too.

I measured 5155 lumens in a lumen tube. Lumen tubes measure lower for ultra wide flood lights because it doesn’t capture the stray spill. Since he measures with an integrated box, it should capture even the farthest spills. I estimate actual lumens should be 15-20% higher than what I measured. Would be interesting to see what Flashaholic measures.

FF’s 22430 battery is MIGHTY IMPRESSIVE!!! It measures 2,112 mah whereas the much larger Acebeam 26350 mah measures 2,111 mah, which is as high as the 26350 format gets.

Ironically the Max Ramp measurement was under spec

Actually the ANSI measurement is bang on in a 22C room. I tend to highlight turn on lumens.

There’s very noticeable flicker under 10 lumens or so

I had a strange issue with one of my NOV-MUs. It was acting very bizarre after a cell swap. Aux LEDs wouldn’t work, modes were all wrong and it kept wanting to going into full turbo with a loud buzzing sound coming from the driver. I just did a factory reset and now it seems to be fine.

Something must have gotten corrupted somehow during the cell swap. Anyone else experience anything similar?

Hhhmmm, sounds familiar, like maybe the fuses aren't set correctly. Oh boy, someone should check what the fuses were programmed to. I had similar problems with the early Q8/Narsil prototypes. Turned out the power spikes the driver gets when installing a battery, tightening up the cap, were causing the MCU to glitch. Think it was the brown out detection (BOD) fuse setting - had to enable it (https://www.engbedded.com/fusecalc/).

On page 19 here of the ATtiny85 datasheet talks about it.

I received my E12R 2 days ago, seems to be decent light, easy to hold and work with and has a lot
of functions however, I am disappointed with the light output. I ordered and received the XPL2 HD 6500
emitters and while it does put out some light, it pails in comparison to my MF01MINI, my Lumintop EDC18,
my FT02S with the XHP70.2 6500 and, has even less output than my very old Skyray 6XT6.

Either the 12,000 rated lumens of this item are grossly overstated or, as an example, the FT02S must
be putting out a lot more because, as you can see, it totally blows the E12R out of the water.

I know this is a very unscientific test but, I took some average readings from my LX1020B Lux meter and the
results are as follows, These were all obtained from a distance of 5 feet, all with fully charged
batts and Samsung 40T 21700’s in the E12R the MF01MINI and the FT02S.

Fireflies E12R = 5000 lux
Skyray 6XT6 = 6000 lux
EDC18 = 10000 lux
MF01 MINI = 19000 lux
FT02S = 31000 lux

As I said, it’s a nice piece that does output some decent light but, since both it and the
FT02S are stated to put out 12,000 lumens, Fireflies must be very generous with their
lumen ratings.

Has anyone else found this to be the case?

It's Anduril 2 so probably ships in "Simple UI" with a max of 6 amps. See the detail specs: ff-light.com - E12R page

How did you measure the lux with your meter. Did you point the light at the meter or ceiling bounce the light with your meter facing up against the ceiling?

My E12R and T9R both came with a default of Advanced UI.

And mine came with Simple UI as default. Curious to hear that yours came otherwise… Anduril2’s stock config is for Simple UI to be the default and Loneocean’s config files don’t seem to override that setting.

The Noctigon K9.3 came with Advanced as default too.

If you point your light direct at the meter, what you are measuring is the intensity and not lumens. Even my tiny TX25cvn with the 700lm W1.1 will measure higher than all the lights you listed. Even ceiling bounce measurements heavily favor throw lights. The E12R is a very floody light. I have both the E12R and MF01 Mini, the E12R definitely makes more lumens than the MF01 Mini.

Another possibility is you probably haven’t entered Turbo on the E12R. In order to get to Turbo, you have to double click after reaching top of ramp.

Sounds like he’s not entering turbo. The light should be able to brute force the intensity over the edc18 on fet

I held the lights 5 feet directly above the meter, no bounce.
