Well… sustained performance is what I wish for and I think every one wish for..that does not mean that very low lumen options are a better option… cause I can get sustained performance using low lumens with this light…

We all want our flashlights to sustain as high of an output as possible for its size. The E07 is actually one of the best out there in this regards for the size and mass. I use my E07 at about 1,000 to 1,500 lumens for long periods, which is as bright as most flashlights of its size running on max output.

The highest sustained output in a passively cooled light is 6,400 lumens, which is achieved by the massive 1,804g Olight X9R with one of the highest surface area (heat fins) I’ve seen in a flashlight. In comparison, the E07 weighs a measely 125g.

You have to understand physics cannot be changed. You can only do so much with a given size/mass and wattage. What the E07 does differently from other flashlights is that it is able to output several times higher than the typical flashlight of its size. But keep in mind, you don’t have to run it at its max. It is an added bonus. For a flashlight of this size, sustaining even 1,000 lumens is pretty much the max allowed by LED tech and law of physics.

Yes but PC industry have the same problems with the physics… yet some manufacture get a lot better cooling with the same mass… so.. yes to think all is impossible will not make any creative solutions… to think that it can be better will…

But yes better emitters would be the best solution…
Does any one have any curve that show us how the lumen and watt usage have changed the last years ?
So to know what to expect the coming years in improvement.

In the case of E07 I have already find one tweak that would help a little bit, it would be to change this “stylish” silver ring with a extended heatsink this would this flashlight to look different… but this unnecessary big ring does not fill any function as I can see… And Also the big ring might look stylish but make it also look less “professional” and more for “home use” a´sane with this AUX lights… not sure what trade offs where made to include these AUX lights… related to cooling.

The steel bezel serves an important purpose. It greatly reduces the damage caused by dropping the light. Converting it to aluminum might help a little with heat, but it would be too small of an effect to even really notice.

I gave some numbers a few posts ago, and they’re not made-up… But I’ll explain in more detail:

The theoretical highest possible efficiency of a lighting device is 683 lm/W, but that can only be achieved with a narrow-band green light source. Regardless, we’ll use this as the baseline for perfection.

An old incandescent bulb gets about 5 lm/W. That’s a 5/683 efficiency ratio. So it wastes 99% of its power as heat.

Many of the LED lights around here get about 100 lm/W. This is dramatically better, but it still wastes 85% of its power as heat.

The highest possible efficiency for a white light source is about 300 lm/W. So even a literally-perfect LED with a 100% efficient driver would still waste 56% of its power as heat.

So… let’s say there’s a light which uses 10W of power. Here’s how the numbers work out:

  • Incandescent light: 0.07W of light, 9.93W of heat.
  • Fireflies E07: 1.5W of light, 8.5W of heat.
  • Literally perfect ideal white light source: 4.4W of light, 5.6W of heat.

But more realistically, taking into account losses from drivers and optics and LEDs, we’d be lucky to make 200 lm/W. And that would produce 3W of light plus 7W of heat. So in the future, a light like the E07 could maybe sustain 2400 lm instead of 1000 lm.

Even at the extreme limits of what is theoretically possible, the E07 would still not be capable of sustaining 8000 lm. It just doesn’t have enough mass and surface area to shed that much heat.

The computer CPUs are MUCH bigger and heavier than the E07 and even then it won’t be able to sustain the heat wattage generated by the E07 on max and still be able to hold it comfortably. For a flashlight to use the same cooling tech as cpu cooling systems, the host needs to be much bigger and will no longer be pocketable like the E07. The recent Imalent MS18 is a great example.

The problem right now is that the higher efficiency LEDs are CW, bad tint, and low CRI. The HI CRI emitters like the SST-20 95CRI and Nichia 219B 9080 are much less than 100 lumens/watt on the higher outputs.

We could use PC tech all we want but PC’s always have a constant supply of air (fans) moving across their heat sources that flashlights will never have.

Here’s what you can do:

Buy this XHP50 × 3 PCB. Get a copper spacer. Make your E07 a 3x XHP50 (3V) mule. It will probably sustain the same lumens for twice (at medium outputs) as long but it will be a hideous looking beam and even heavier up front. Did I mention it will be 10K lumens turbo?

some other complaints I have about the flashlight is… its way too big step from high to turbo mode… I would also want to be able to ramp up to turbo mode… or atleast half turbo..

But I think the most stupid thing with thish flashlight is that for some reason you have to double press twice to enter turbo ? what is this, some kind of “child/security” protection ?
This is very stupid and not necessary, I am pretty sure all agree with me. I am not the only one who complained high to turbo is too big step…
or the high setting is too low.. compared to turbo..

It really get very very hot… I wonder… what temperature in celcious should I set I am going to try to reconfigure the sensor.. next week.. sigh
is 90 degrees safe for the electronics ?

Anduril UI can be programmed to ramp all the way to turbo. You get the flexibility to program the top of the ramp to whatever you want it to be.

Hi all,

What’s the mcpcb size for the eo7? I’ve been wanting to convert it to an dedicated mule, the mcpcb is a bit too deep, thinking of adding spacers to bring it up closer to the glass

Is Samsung 40T currently the recommended cell to run XPL HI?

I read 5OE will fall on face fast pushing XPL emitters at max?

Any of those should keep the voltage up nice and high for XP-L.

I just got mine and have to join with everyone in saying how nice this light is. I just keep playing with it. Of course you guys have now ruined me for anything without Anduril and Nichia LEDs.

How long does it usually take to receive flashlight from ShenZhen using FF offered free china post?

Do customers get shipping notifications?

I contacted FF Jack but haven’t heard from him in a week

Usually takes 3 weeks to 4 weeks from Fireflies/Neals.

Actually i ordered from Fireflies. The emitter i wanted only appeared offered directly from FF ~ XP-L HI (V3) 5000k

Price was comparable to Neals after discount code

This is my first China order so little nervousness even if PayPal insures

Is there still a working discount code when ordering directly from the Fireflies website?

E07CU10

^ This code 10% off was givin specifically for Ti Cu E07

I would email Jacky Chan and ask for others if needed

Cheers!

@pennzy, having ordered a FF E07 back in late June, and received it in July, I can confirm that everything is fixed.

I think I’ve seen the number of the highest regulated level somewhere in this thread, but I lost track of it. Facepalm
Does anyone know what is the highest regulated level (7135*3 maxed out) and how many clicks do I need to do to set it to that level?

Umm, I want lumens but I want CRI too...

Tried searching but couldnt find the info. Does anyone know what tint bin is used on the sst20 4k emitters? I am finally going to pick one of these up, just undecided on Nichia or sst..

If you have to ask just get the Nichia. At the power level these will run (because 7 emitters) it will always be “greenish” at lower levels.

Easy enough to put a lee filter between the optics and lens. Fireflies seems to be using different bins at different points in time during their production. Early on when during their first batches of ROT66, I received neutral/rosy SST20s. Those with a lee 804 filter is amazing. Very recently I got a Cu E07 with slightly green SST20s. Even with a filter on low modes, they’re just okay.

I just swapped out the stock lens with UCL 35.00mm x 19.00mm lens and got the following measurements:

E07 XP-L HI 5000K w/ stock lens
lumens: 195 lumens
CCT: 4957K
DUV: 0.0025
Ra (CRI): 72.3
R9: -22.1
Rf: 69
Rg: 97

E07 XP-L HI 5000K w/ ucl lens
lumens: 198 lumens
CCT: 5030
DUV: 0.0003
Ra (CRI): 72.6
R9: -19.2
Rf: 69
Rg: 98

E07 XP-L HI 4000K w/ stock lens
lumens: 443
CCT: 4146K
DUV: 0.0030
Ra (CRI): 72.7
R9: -22.8
Rf: 71
Rg: 95

E07 XP-L HI 4000K w/ ucl lens
lumens: 454
CCT: 4184K
DUV: 0.0010
Ra (CRI): 73.3
R9: -18.9
Rf: 71
Rg: 96

I’m pretty impressed with the results. Dropping DUV by 0.0020 is quite a difference. That amount of green reduction is between a Lee Filter Zircon 804 and 805. However instead of losing 15% output, it actually gains 2% output.
