was going to get the first until I saw the 2nd offering. Saved my money for that one. Now I won’t get the 2nd offering but will use the money for this EO7. Please don’t advertise a new light until the previous one is available 
+1 Absolutely
Btw, I think I will get a PL47 with Nichia 219B sw45k, but that will not hold me back in getting this light, too. Especially, if Samsung LH351D is also considered (LH351D has 90CRI 6000K CCT, which could be an extraordinary choice for people loving CW, but hating low CRI - and I would be happy to see 5000K and 3500K as well).
Would also love to see more mass in this for better heat sinking, hopefully it will be heavier than the D4S. I don’t want another D4 where lumen output drops rapidly the moment you turn it on and gets hot within seconds
If it was between the three and I didn’t have either, I’d get a ROT66. They are freaking awesome. The 2nd one, the angle light, is very interesting and could be quite industrial around the house if you’ve got the balls to take it off the night stand. This 3rd offering is sort of like a ROT66 IMO with two less emitters and more traditional battery tube. Nothing at all wrong with that but again if I had to choose, ROT66 wins all day! I don’t see a need in the drawer for both. ROT66 is to me one of the most all around useful, powerful, good looking small, floody with good reach, torches in the world for sale. Ask my wife, she absconded with my first Nichia R9080 so I had to buy another!
Very interested, but I want to see output and throw. It’d be complementary to the rot66 (which I just ordered) because I can EDC it.
Needs a very high current battery as well 
I’m not so happy with the led choice, no XPL-HI 5D and no 219B. I wonder what would be a better mod, mixing three 3000K and four 4000K Samsung LH351D’s or seven Luxeon V’s.
USB charging is a gimmick which rises the cost and is prone to failing, don’t do it.
It should be possible to turn off the aux boards through the ui.
Copy the switch design od the D4/D4s couse it’s pretty well done, on the ROT66 it’s difficult to find the switch. But on the render I see something is done about this.
It would be extremely nice if a wider (widest) frosted optic would be available to buy separately.
A big big :+1: for using Anduril and the 21700 format. Hope Emisar will catch up because this light i way more interesting then the D4S imho.
I agree 5D/5A is one of my favorite tints and looks just as nice as 219B 9080 except for color rendering. Mixing cct would be a great option because the resulting tint looks amazing from what I’ve seen.
USB charging is not a gimmick. Some of my friends who are interested in these high power flashlights, but are not flashlight hobbyist like us, are only interested in buying flashlights that have built in usb charging. I help them buy lights like the TC20 and DN70, which they only use USB to charge. I also like to have usb charging for just-in-case eventhough I never really use it.
One of my most favorite lights is my 2014 DQG EDC Triple 26650 Flashlight with the XP-G2 R5 4A. This new E07 is nearly identical in dimensions and won’t have the really irritating 2 second hold to turn off the light :person_facepalming:
Hey, FireFlies, please include a strong magnet in the tail and the ability to set the intensity of the aux leds. I want the aux leds bright enough to use as a night lite, just like the ones in my Emisar D4S.
I have yet to purchase a SST20 4000K light. I think this will be my first one. Looks good!
I received 2x 21700 40T’s
Just waiting for suppository duty in my ordered PL47, and this one when available. :smiling_imp:
This light will be pocket king.
I just realize the weight is specified at only 138g, which is even less than the Emisar D4S that weighs 142.0g. Very disappointing considering this has 7 LEDs and D4S has 4 LEDs. This light will be another hand burner like the original D4 which cannot maintain any useful lumens due to poor heat sinking. I hope Fireflies add at least another 40g to the head otherwise it would be a waste of a potentially great pocket flashlight that could also serve for practical use.
Yea, fill in the USB charging you love so much with a thicker shelf and scrap that. Done.
40g will add just mere seconds of turbo time and won’t do anything to sustained output.
Myself I prefer lighter. And with charging.
The D4S vs D4 is night and day difference. The Sofirn C8F also kicks ass in sustaining output compared to the D4S. Even if the extra mass doesn’t add a whole lot of turbo time, it can at least sustain the lower outputs far better.
D4S also more surface area than D4. Extra mass will only add like 20 seconds to turbo runtime, what you’re really after for heat dissipation is surface area. The 7x emitters will have a very high turbo output yes, but what the sweet spot here is more efficient lower outputs. It won’t be able to maintain 1000 high cri lumens with perfect regulation like the ROT66, but probably more along the lines of 400.
With a 1.5” head, I think it will be too big for pocket carry anyways outside of cargo pants and/or jackets, so a slightly chunkier body probably wouldn’t hurt, but I wouldn’t want to make it too bulky and/or sacrifice usb charging.
Please describe the heating difference in detail Sofirn C8F(18650 or 21700?) and D4S.
I like the adding mass idea. And i agree that surface area is also important. I built a heat exchanger gadget to cool my laser and to create more surface area all i had to do was add more cuts in the aluminum. I was working with 1/2” Al, stock and what occurred to me as i was fabricating, was that each cut i made added surface area —more access to air to remove heat. If i just kept the 1/2” x 2” x 4” block i would have roughly 22” of surface area, but if i made a cut perpendicular to the 4” side i add roughly 1 7/8” of surface area per kerf/ slice.
So, for my gadget, the aluminum absorbs heat from water thru copper tubing and a fan runs blowing air thru all the nooks and crannies removing heat. Note: i have no scientific evidence to support this hypothesis, just gut and instinct. I think i am right—but i dont know for sure.
Point is, i suspect the 4 or so fins they have milled in the prototype picture may be increased to effectively double and triple +, the surface area—more contact area with air, less heat. Also, i think i found information suggesting copper was a better conductor of heat. And depending on alloying of the Al, the copper seems stouter than the aluminum in my opinion.
I would add a picture to show what i built, but dont see a way to attach local files, from my phone.
Nice!! Interested!!
