Charging the battery brought the aux lights back. I feel like a dolt. Thanks, everyone.

I wonder if any of you could help with my Emisar D4S problem: http://budgetlightforum.com/comment/1567444#comment-1567444

Wow, thats good news,, and you must be happy . I didn’t think that would be the solution. Great Forum we have lots of help.

This thought struck me… there is a lot of functionality in the firmware… but yet..there is no mode to turn off leds…
For instance…as a power save mode you could choose to not activate all leds… for instance… you can sacrifice width of the beam in favor of throw. Cause not always you need this wide beam…
Plus it could save a lot power…

E07 is great.. but.. battery when using high lumen settings… will deplete kind of fast… but its not strange..
All I am saying is if you could turn off leds.. to make beam less wide but not sacrifice throw it could bee a good compromise should it would require more physical motion and focus with your hand to focus the beam to the objects..but… to save power it could be worth in in some situations..

Just some ideas for future products… 7 leds is good..but it might not be all scenarios we need to use it.. if we only want focus beam with long thru we could give full power turbo to just a few leds.. and let the other be off..

An other idea in this mode would be that the firmware would alernate the active leds.. when some led turn of some other turn on.. the idea would be.. as soon as one led get hot a new “cool” led would start and when it get hot it turns of and a new led start.. that is cool… it could maybe help thermal performance.

And other idea… is in situation when throw is more important then flood… maybe we could give specific leds extra turbo power which might be possible cause not all 7 leds are running at the same time…

Just some ideas.. I like to think outside the box…
With a a firmware complex like this… this kind of functionality is not to far off I think…

E07 is a very good flash light that gives both of best worlds its a flood and throw light in one…
if we could deactivate we could control flood level and maybe even surpass throw with more narrow beam…
The whole idea is to make the flash light even more versatile ofc..
As it is it s already the most balanced and versatile flashlight.. ist flood and throw in one.. but atleast witht the SST20 the throw could maybe be better…considering the lumen output…

Being able to select any amount of LEDs requires separated channels per LED, which means each channel needs it’s own regulator/FET and enable signal from MCU, or some logic chip to route the signal to the selected channels. As a hobbyist driver designer myself I can only say man, what a nightmare.

If it used only 1 of the 7 LEDs, the beam would still be just as wide. Increasing the throw isn’t done by using fewer LEDs, it’s done by using larger optics or smaller LEDs. Even if it could turn individual LEDs on/off, the firmware can’t change the physical beam pattern.

Turning most of the E07 LEDs off would only produce this effect, which doesn’t help at all with throwiness:

AND if you want a thrower of the same size the E01 is it!

What could be done however, would be to place a very throwy LED in the center(SST-20) with a low angle emission optix, and pick floody LEDs(LH351Ds) with floody optics.

Best balance between flood and throw.

Only problem is the driver as MikeC stated, along with making a custom optic.

With 1 battery and 7 LEDs in parallel it’s hard to drive any single LED to its max current though (and therefore max throw).

It’s not really worth it on this light but the idea isn’t completely without merit.

There are designs which can do both flood and throw. For example, the lights shown below. But the E07 isn’t like that. All of its optics are the same, so turning individual LEDs on/off doesn’t really change the beam pattern at distances greater than ~20 cm.

I noticed there is generation II of ROT66 and PL47. Any plans for new version of E07 soon?

I just got the E07 w/ the SST-20 2700K. It has a really pleasant rosy tint. The SST-20 2700K seems a bit rosier than the 3000K. I ordered it with red Aux light but it came with purple Aux Facepalm The SST-20 2700K w/ Red Aux lights would make for a perfect bedside light due to it’s very low blue wavelength emittance so it won’t suppress melatonin as much as other lights. Also red light is known to induce sleep among other benefits.

I noticed an issue with the translucent o-ring between the battery tube and head seems to keep squeezing out when tightening the head and sometimes it prevents electrical contact. I think a thinner O-ring would fix the problem.

Here are test results using fresh off the charger Samsung 40T.

Turbo (with stock lens)
Output: 3,845 lumens (at 1s)
CCT: 2629K
DUV: -0.0023
Ra (CRI): 93.6
R9: 70.3
Rf: 88
Rg:105

4th lowest stepped mode (with stock lens)
Output: 119 lumens
CCT: 2661K
DUV: 0.0001
Ra (CRI): 97.5
R9: 85.2
Rf: 95
Rg:102

Turbo (with UCL lens)
Output: 4,043 lumens (at 1s)
CCT: 2629K
DUV: -0.0024
Ra (CRI): 93.6
R9: 70.3
Rf: 88
Rg:105

4th lowest stepped mode (with UCL lens)
Output: 123 lumens
CCT: 2682K
DUV: -0.0002
Ra (CRI): 97.6
R9: 86.3
Rf: 95
Rg:102

I’m surprised this time the UCL lens hardly lowered the DUV. I saw much larger improvements from switching to UCL lens in the several older E07 that I tested. Maybe Fireflies got a new/better batch of lens. Overall, the E07 is still one of the best single cell flashlight money can buy.

For the E07v2, I hope to see a slightly longer battery tube with longer springs with better mechanical properties so it does not get permanently crushed when using longer batteries; permanently deformed (shortened) springs results in poorer electrical contact, higher resistance, and less output.

They seem to have updated it slightly, without changing the name.

I asked them a month ago. They said they plan to release a second generation E07 next year.

Thanks for the test! I wish more flashlights had SST-20 2700K JA3 as an option.

I sent my Copper E07 to the US facility over a month ago after it broke and I have not received any word of anything yet. I have tried emailing Jacky and have not heard back.

Now my Brass E07 is completely dead too.

What is going on with this? Is anyone having such a bad experience as me? Has anyone heard from Jacky recently?

This is completely unacceptable.

what does tracking say? i hope u didnt send it uninsured no tracking nr.. it seems they dont offer the best customer support and that is bad imo..

I regret not doing that in the first place. I just want the damn thing back so I can send it to Vinh and get a working light back.

I just heard back from Jacky. I will be sending him a video and hopefully he will be checking up on the status of my Copper E07. I will update as this is dealt with.

I don’t know how the Brass died, it had very little use. One morning I woke up and the AUX leds were off, I then trouble-shot it but nothing worked, just a totally dead light.

The Copper had a number of issues. Wrong Aux installed, dead aux lights in switch…. can’t remember the rest honestly I’d have to dig up the old emails.

I found this optic on Alibaba: https://www.alibaba.com/product-detail/LED-module-lens-7-in-1_6072928070...

It seems it would fit the Fireflies E07 and has many different angles to choose. The seller told me they have a MOQ of 500 pieces with 0.27$ per optic. They don’t sell smaller quantities for personal use. I haven’t found this optic anywhere else.

Even if the position of the LEDs is correct, the position of the optics legs isn’t. In the one you showed there are 3 in the middle, and originally there are 4 on the edges in addition, forming a rectangle.

If you look at the drawings and the measurements you see that it actually has four legs. Similar to this one: https://www.alibaba.com/product-detail/35mm-7-in-1-module-pmma_607991889...

According to the shipper customers can receive their orders in 3-4 days. let’s see how it works.

I bought a used e07 and it has no candle/lighting/temp calibration modes…is this the simplified UI you are talking about?

I tested my two new E07 additions with the Texas Ace Lumen Tube calibrated with Maukka lights and Sekonic C-800-U spectrometer. Lumens taken at 2 seconds.

E07 Copper XP-L HI 5A Turbo 7,112 lumens 4252K -0.0047 DUV 72.2 CRI   -17.2 R9 45.9 R12 67 Rf 98 Rg 30T
E07 Copper XP-L HI 5A Mode 7 2,397 lumens 4157K -0.0041 DUV 72.1 CRI   -17.6 R9 45.6 R12 67 Rf 99 Rg 30T

E07 Copper XP-L HI 5A Mode 5 373 lumens 3956K -0.0010 DUV 72.8 CRI           30T
E07 Copper XP-L HI 5A Mode 4 171 lumens 3958K -0.0010 DUV 72.8 CRI           30T
E07 Copper XP-L HI 5A Mode 3 66 lumens 3945K -0.0008 DUV 72.8 CRI           30T

E07 SST-20 4000K FA3 Turbo 4,310 lumens 4120K -0.0038 DUV 95.5 CRI   86.7 R9 84.3 R12 92 Rf 103 Rg 40T
E07 SST-20 4000K FA4 Mode 7 1,750 lumens 4165K -0.0010 DUV 94.4 CRI   87.4 R9 82.0 R12 92 Rf 103 Rg 40T
E07 SST-20 4000K FA5 Mode 6 752 lumens 4159K 0.0001 DUV 96.0 CRI           40T
E07 SST-20 4000K FA6 Mode 5 324 lumens 4055K 0.0006 DUV 97.8 CRI           40T
E07 SST-20 4000K FA7 Mode 4 148 lumens 4045K 0.0004 DUV 97.8 CRI           40T
E07 SST-20 4000K FA8 Mode 3 58 lumens 4058K 0.0003 DUV 97.8 CRI           40T
E07 SST-20 4000K FA9 Mode 2 14 lumens 4072K 0.0001 DUV 97.4 CRI           40T
E07 SST-20 4000K FA10 Mode 1 3 lumens 4076K -0.0001 DUV 97.0 CRI           40T



The FA3 tint bin is the rosiest SST-20 4000K I've seen to date and I've seen MANY! It's better looking than the FD2 in the FW3A, FB4 in the Emisars, FD2 in the Mateminco/Astrolux, FB4 in the Acebeams but it is still nowhere as rosy as the XP-L HI 5A tint, which is perfection. The copper E07 is gorgeous! It's a must own for any flashaholic! Goes really well with the Red Aux light IMO. Also this time around UCL lens didn't improve the tint much. Only dropped DUV by about -0.0003 to -0.0004, which is not noticeable at all. The UCL lens improved tint much more in the older E07 batches. I guess the lens used in the recent batches are improved from the older batches.

Edit: I just realized that the optic used in my latest two E07 is narrower throw than the optic used in the older E07. Comparing my new E07 SST-20 with older E07 SST-20 and comparing my new E07 XP-L HI with older E07 XP-L HI, it is very obvious that the hotspots from the newer E07 are smaller compared to the hotspots of the older batch of E07 using the same emitter. However, I cannot tell a visual difference in the optics.

So my (new to me, bought used) e07 has crushed the top of my Sofirn 21700…was there any resolution to fixing this issue? As far as i can tell, my version is one of the newer models…
