Interested in Copper Titanium E07
Interested in full copper limited edition. I’ve been emailing Jacky at fireflies to get some information. Very excited for this version.

Full copper vs Ti/Cu….
The Titanium almost acts as a thermal blanket or shield to protect the cell from intense heat of the 4 emitters, the copper pill will absorb and radiate heat allowing the emitters to run efficiently but the Ti body/battery tube won’t readily absorb this heat, effectively keeping the cell as cool as possible while the light delivers optimum output.
Whereas, a full copper build will pull heat all the way to the tail, surrounding the cell in heat and possibly causing damage or a dangerous situation to the Li-ion cell inside. Yes, it will pull more heat from the emitters, but it pulls it to the dangerous cell within… not a good compromise in my book. And I am probably the biggest advocate for the use of copper on this forum…
As an aside, the Ti battery tube will remain much more comfortable in hand than a full copper build, which would get too hot too hold in short order.
but… but… it’s about looks, I want full copper too 
Same as I’d like to have full titanium or at least titanium+clear ano head.
Would love to have a glimps of E07 Cu + Ti edition before deciding purchacing one.This would be a great splurging out a flashlight.
You’re assuming people are going to use the light exclusively in turbo or very high outputs. I’m also assuming 90% of use case will probably be below 500 lumens. The other 10% will be showing off to friends with a 10 second turbo blast.
Interested ti/cu
Ti/Cu interested.
Why so many of you love this flashlight? Its just cos the output?
Not only the output.
It has a very good user interface(Anduril), has access to high CRI LEDs(SST-20 4000k and Nichia 219B), has 21700 support, an excellent design, AUX LEDs, etc.
Interested ti/cu thanks.
Yup!
well ask yourself why the emisar d4 became so popular ? same with this, nice looking light ( the clear anodize is very pretty ) nice ui, tint options etc and u have a winner. i have the sst20 4000k, so not really that much higer then my d4/d4s, but i got it because i like the looks and i got a reason to buy first 21700 light.
Count me in for one please
Yeap. Measured 7100 lumen @ turn on, using 21700.
I don’t assume anything.
There is no way I can speak for what anyone will do with such a light as this, but it has 7 emitters and can produce a lot of heat, better to keep that heat away from the cell if possible.
Mine makes 10,000 lumens, I don’t want a copper tube in my hand under this level of power so I speak to this end. It doesn’t require full Turbo to get hot, anyway… and besides, I may make this one do more than the last one. 
To what end? Others might not want or need that extreme level and could enjoy the copper tube.
Can someone tell me how to set thermal temp limit… i want to make it higher. I dont like to read manual.
Ti cu interested
The manual really is pretty well laid out, and a good supplement to the graphic:

Thermal config is under blinky modes, starting at line 74. It might seem complex, but each step is very simple.
From off:
- Triple click to enter blinky modes (starts at battery check)
- Double-click to sunset mode
- Double-click to beacon mode
- Double-click to temp-check mode (will blink out the current temperature)
- Click 4 times rapidly to enter thermal config
Light will blink once, signaling temperature calibration, then start “buzzing” or blinking rapidly. If you want to set the ambient room temperature (do this when the light is cool), while it is “buzzing,” click the number in degrees Celsius (eg - 21 degrees C or 70 degrees F, click 21 times).
When done, or if you want to skip temperature calibration, wait for the “buzz” to stop. Light will blink twice, signaling temperature limit, then start “buzzing” again. Click N times to set the maximum temperature as N + 30 degrees C, then wait for the “buzzing” to stop. So if you want 55 C, click 25 times.
