FireflyLite E12R 12*emitters 15000LM 1x21700 Flashlight

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.

Price?
Thank you

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.

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

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

The design seems to have further reduced the mass of aluminium that could conduct heat away by adding a ‘heat sink’ groove right where there should be a large body of mass to conduct heat away. It appears to be bottlenecked at the place that most needs material.

Bonkers! Haha

Edit: Just saying I can’t recall a design that undercuts the diameter of the aluminium that houses the mcpcb quite like this.

Let’s hope this uses Anduril 2. Anduril 1 is an enthusiast only firmware and not good for gifting to muggles.

Why not just E12? According to the number of leds.

E12R, the R stands for rechargeable. This has USB-C recharge at 2A. Thats a very good recharge rate.
