A buck driver would make this a perfect flashlight for red leds and E21A.

(1) Could you offer some 660nm red led, like SST-20-DR, or XP-G3 Photo Red?
(2) Could you offer some 730nm red led, like SST-10-FR, or XP-E2 Far Red?
(3) Could you offer E21A?
(4) Could you offer sliced LH351D? Slicing makes LH351D warmer and more rosy. I would really like sliced LH351D 2700K, it could have a CCT of about 2400K and it would probably be below BBL.

I would buy at least 3 660nm red flashlights, at least 1 730nm red flashlight, and also some with E21A.
I would also buy at least 2 sliced LH351D 2700K flashlights.

Thanks for your input.

I understand red light is for some special use, hunting , signal light etc. but Why using red leds for such a powerful floody light?

We do not supply sliced LH351D, just regular LH351D available.

For E21A light, it is another firefly project.

It is a powerful floody light when used at max power, but we do not have to use max power. It can also be an efficient dim floody light with long battery life.

There has been quite a bit of interest on BLF in deep red flashlights recently. Sofirn C01R sold out fairly quickly.

Many special uses:

  • night light that does not contain any blue light, which causes suppression of melatonin and prevents you from sleeping
  • once your eyes adjust to the dark, deep red light allows you to see clearly without destroying your night vision
  • some animals cannot see red light
  • some insects are less attracted to red light

The configuration sounds great; I have two requests and a comment:

  • Source the high CRI emitters from a bin just below the BBL; rosy tint is preferable to green tint
  • Removable magnet in tailcap; magnets interfere with magnetic strips and mechanical watches
  • Your new name is lengthy and awkward; Fireflies worked OK

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.

Acturally compared with ROT66 , E12R has got more heat-sinking surface due to more and much deeper fins. Heat-sink is not a weak point for E12R. Turbo mode is only supposed to be a short-time use, in this case , adding more weight wont help too much for more runtime on turbo, anyway E12R is not designed to be a bulky light. We still keep it in compact range as possible.

Will there be an all black version like the ROT66 with Aux Lights?

2700k or 3000k, below BBL, please and thank you. Thumbs Up

Hi Fireflies,

Are you thinking of offering a discount group-buy to give this model a sales jump start?

It generally produces much more initial interest and generates many more marketing reviews from knowledgeable socially connected BLF members.

An E12R version with LH351C should be still considered. (A bit less output on turbo /maybe a few percent/, but more throwy beam compared to LH351D, which many of us would like).

Unfortunately, besides the E21A, there really isn’t any readily available below the bbl 2700k or 3000k emitters.

Fireflies already offers SST-20 2700K JA3 CRI95 for other lights, which is below BBL when driven at high power (AFAIK), but above BBL when driven at low power.

True, the JA3 bin from Fireflies was the best tinted SST-20 2700k I’ve seen. Basically on the BBL at low currents and below BBL at high current. Still not as good as the E21A 9080 I’ve seen.

Interested if we can get SST-20 2700k.

They do have the SST-20 2700k and its the best batch I’ve seen in terms of tint. You can email them to make a 2700k version if they don’t have that listed as an option. That’s how I got a 2700k E07.

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.

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

I will start a new OP for E07 Gen2

Thank you so much for listening.

I also love the name Fireflies, and I also wanted to add to what the poster above said about how “Lite” really is just another way to say “weaker” & “cheaper”. But I am so happy to see that you are so willing to listen to our feedback. I really just wanted to write and tell you Thank you so much for being so open.

I LOVE your lights and I can’t wait for more of your work. ROT66 Gen2 Nichia 219B is my all-time favorite light. I’m kinda worried that one of your new lights is gonna knock the ROT66 off my throne, but I guess that’s a good problem to have

Thank you again Sincerely.

Yes, new optics also works with ST20 emitters , But LH351D hi CRI version can get much more lumens , why still choose ST20 2700K of much less brightness?

If the emitting spectrum is examined in both LH351D and SST-20, the reds in the SST-20 are more complete. This is especially important and noticeable, if we go towards warm white. An emitter being 95 CRI instead of 90 CRI means that, the SST-20 is twice as good as the LH351D, if we treat those numbers as subtracting them from 100 – it is half of the errors in color rendering.

This would mean, that if Luminus would make 95 CRI SST-20 in 5000K, I would also not hesitate to choose that over the LH351D, but for now, in 5000K CCT, the LH351D remains the best 3.5mm×3.5mm footprint LED. Nichia 219C is only marginally better, and it is less efficient.

Most of us who already own many other flashlights care a lot more about LED type, color temperature, and tint than lumens or price.

Someone who specifically asks for SST-20 2700K JA3 is unlikely to settle for LH351D 5000K CRI90, and probably doesn’t care that SST-20 2700K outputs fewer lumens. The difference between 7000 lumens and 12000 lumens is barely noticeable, while the difference between rosy and green tint or 2700K and 5000K color temperature is very obvious.

If you can offer E12R with a variety of good LED options, you will probably sell more of them.

Here are some I would buy:
warm white XP-L HI, like XP-L HI 7A 3300K
warm white LH351D, like LH351D 2700K CRI90
Nichia 219B sw45k
XP-E2 Amber
SST-20 Deep Red
XP-E2 Far Red

CRI and color reproduction aside, the advantage over SST20 is that it is more throwy than the LH351D. The challenge with multi emitter lights is they tend to be very floody. By using SST20, you get increased throw but decreased lumens. The increased throw will possibly be more useful depending on intended use, and is my personal preference over LH351D. It is easier to diffuse a light, but you can’t make a floody light more throwy. That means the SST20 gives better flexibility.

Wouldn’t that depend greatly on the emitter, ambient temp, and how much of the light was being held by a hand(at whatever temperature)?

219B-V1, please.

My spoiled eyes won’t let my mouth call these Samsung LEDs high CRI. They’re great, probably. Just not what I want.

The light seems to be really decent, I’m just unsure if I’m willing and still able to perform a successful 12 emitter swap plus leaving the AUX LED’s untouched.

Yes it would, but I think it is something that manufacturers need to be more honest about. I know so many muggles who have bought a zillion lumen pocket rockets only to find out that after a few minutes they are dimmer than a $20 light from a hardware store.
