FireflyLite E12R 12*emitters 15000LM 1x21700 Flashlight

[pol77]

I am definitely getting one with E21A or 219b, if available, when it is made in Ti / Cu, which I hope it will.

Looking forward to it! Great project with interesting driver. Finally no AMC+FET driver!
Guys, please, why do you change such great name as FireFlies to this Firefly Lite? I deffinitely like the old one much more!
I really appreciate LH351D default choice - I would like to see not only 5000K, but also some warmer tint choices. Please don’t forget about XP-l Hi and SSt20 4000K 95 CRI among available LED choices.
Keep it up, you have my support with this project

I agree with everyone else here, keep the fireflies name.

In English the word lite means something that is made smaller or cheaper. For example a software package that is cheaper and has less options would be called lite.

Lite is not a creative spelling of light, it has a completely different and negative meaning.

That may be why everyone has the negative reaction to the name.

Fireflies is simple and beautiful.

Fireflylite creates an immediate negative reaction.

And thank you for your amazing flashlights. The E07 is my favorite flashlight and the PL47 is my favorite headlight.

Is there going to be a E07 gen2 coming? I would like to see one with a deeper optic and more throw, similar to the optic in the astrolux mf01 mini.

This config is right up my alley. Possible W2 emitters? Is the magnet removable? That looks like a stainless steel bezel, and those look like throw optics.

The fifth pic, the General Prohibition Sign: That’s me, doing that, all day long.

The magnet is built in tailcap and removable , The optcis is 30 degree-Mid-flood and a bit throw.

I will also add a few comments from myself.

1. Keep the name FireFlies. Why do you want to change it at all? FireflyLite is terrible.
2. Make removable magnet in the tail.
3. Make pads on the driver for reflashing.
4. AUX leds on the main mcpcb may make it difficult to replace the main LEDs. A separate board more practical for us, but probably not profitable for you.
5. Use throwy optic. If possible add floody optic (like for ROT66 g2).
6. xp-l hi is better choice in such lights imho.

Not to be negative, but what kind of runtimes might we expect with this compact but extremely powerful light at higher levels? Is there a similar sized-light that we might extrapolate from?

Also please change the name back to Fireflies. FireflyLite is terrible.

C’mon, it’s half the calories of regular Firefly…

Very compact: Check good.

Very powerful: Check good.

Runtime: Two out of three is good. Which two do I want, and therefore, which third, do I have to have?

Single 21700, somewhere around eleven thousand turn on lumens, head size and head mass is the size that it is, so I would like to add this light to my collection to be with my MS03, EC03, FW21pro, NSX53, and TM9K. What do I get from those five lights? Very compact and extremely powerful, but run time is limited by fuel supply per power ratio, and is also limited by compactness of heat sinking/heat dissipation. I love those other five lights, so I know that I will also love this light. Choice of emitters and optics: I like some more power with a little less throw, and I also like some more power with some less throw, too.

It has normal modes for normal runtime.

If I want eleven thousand lumens for more time, then I need a bigger light. Even more time at eleven thousand lumens? Then I need an even bigger light. I can run my MS18 at 11,000 lumens without heat or fuel concerns until the New Jerusalem descends from Heaven to Earth. But I don't. Instead, I run it at 100,000 lumens until I need to charge it and let it cool off.

I have lots of lights that have very steep power/time graphs. I love them all. There are also lots of lights that have one tiny emitter sitting on top of ample fuel supply, replete with very nice power/time graphs. Because they are not very powerful per compactness, I have not purchased any of them, yet.

NOTE: All the prototype photos above do not represent the final E12R in mass-production.

Very interested! So is it actually in production? Is there a target date for release?

in production already. It is scheduled to be released at early November

Thanks for explaining. We did not aware that. now we have to make a deliberate decision about the new name. :person_facepalming:

I will start a new OP for E07 Gen2

Wow. If E07 V2 comming out then that is my prefference. 12 emitters are overkill for my needs.

magnet removeable

Driver comes with reflashing pads

integratered DTP MCPCB does not save cost, it saves some assembly work though, Replacing main emitters is not complicated, no much difference with regular MCPCB.

New optics is mid-throw-flood, only 30degree available.

Price?
Thank you

[Yournamehere90]

I’m pretty sure the name changed because of some copyright issues and it wasn’t something they wanted to do.

The LH351D will be nice. I’d love to see an E21A version also.

[Lightbringer]

There’s always “LightningBugs”. Or “FireBugs”.

[0oklight]

I don’t understand why there is little aluminium mass directly underneath that plate of LEDs (think ROT66) and all that heat sinking around an area that will hold little more then a switch.

Not an expert on thermal management but I challenge some of the smart people here to talk me thru how this design is going to manage the heat.

Or maybe that’s not the point in this case and if so apologies for raising this.

How can you tell there is little aluminum mass? The E07 had a very thick aluminum shelf under the mcpcb. It had some of the best heat sinking property for its size. I hope the shelf thickness, which is most important for heat transfer, remains thick like in the E07
