FireflyLite E12R 12*emitters 15000LM 1x21700 Flashlight

Jack, please make 2 optica like in recent rot66 (i think) floody and throwy

looking good :+1:

my next buy

Regards Xandre

warm, neutral and cool white option please.

+1 for many ideas outlined here above.

No one ever did a proper multi E21A flashlight (with more than 4 pieces of E21A), so I will definitely buy it, when I see one proper design coming alive.
Please note, that clear optics are not the best for E21A though, so it will need to be frosted or beaded.

Shaving LH351D is a good idea not only for making desired tint changes, but also it helps with beam quality regarding radial tint shift.

I go even further in another direction: If LH351C could be possible, that would even cut a small portion of cost in multi emitter flashlights, but it would result in smaller light emitter surface, which could mean more throw.

LH351C can be still driven above 3A safely (in a test documented here on BLF, it survived even above 5 A, but let’s keep a safe margin from that), so it could even fit both the E12R and PL47 better:

- for E12R, more throw would be desirable, and anyways, a 21700 cell would not provide more than 100W safely, and there are 12 emitters in that flashlight, meaning about 8-8.5W power per emitter (between 2A and 3A) each. Already by using LH351C without being shaved, that is a noticeable increase on throw.

  • for PL47 G2, 4 pieces of shaved LH351C could be the best idea. I would choose 2700K, 4000K and 5700K 90 CRI tints for this kind of use.

Looks great, keen to see these for sale.

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 :wink:

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.

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?

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.

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

Interested/following

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.
