Yummmmy. I’m in
I like the emitter options and the high effiency driver. Been waiting for something like this. Just wish the head was a bit smaller but 12 LEDs is still pretty impressive for the size. Also please change the name back to Fireflies. FireflyLite is terrible.
I like it.
Suggestions:
~Crenellated bezel
~TIR Optic designed for narrow beam throw… or medium throw.
Too many multi-led lights have a super floody “wall of light” beam pattern. I’m sure we all already have several in our collections, right? Please make this one more throwy.
I agree, Fireflies is a much better name than FireflyLite.
IMO the W1 would make much more sense in this light.
looks nice
Looks great! Please make in copper 
Me too, Fireflies sound right than fireflyte
The use of a buck driver has made me interested in this light.
I would love a 4000K 95CRI SST20 version. Its not as bright at LH351D but it is more intense which is useful in a floody setup like this.
Aesthetics look nice too.
+1
This would be a great light for using multiple tints or even tint mixing / tint ramping. For example, here an idea I once had with the 7-LED optic using 3x 2.700K 90CRI + 3x 5.000K 90CRI + 1x SST20-DR 660nm...
With the 12 LED optic, the inner 3 lenses could be outfitted with Luminus SST20-DR 660nm for deep red light which is great for preserving one’s night vision capability or to avoid attracting insects.
ToyKeeper had some great idea to add red light into the tint ramping of Sofirn‘s LT1 lantern, so this flashlight could maybe offer stepless tint ramping from 5.000K to 2.700K to deep red light.
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?
SST-20-DR 660nm has a much lower forward voltage than white leds, so it cannot be mixed with white leds in this way until unless we have flashlight drivers that can drive it separately.
Interesting design, especially the new driver. If it runs Anduril properly and meets its efficiency target, and can physically fit in other lights such as the ROT66 or even the E07, it could increase the appeal of existing products, too.
Jack, please make 2 optica like in recent rot66 (i think) floody and throwy
looking good 
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.
