Fireflies E07 preview

No, it’s not that. Gold plated contacts don’t oxidize unless the metal underneath melts.

And since the E07 is very recent, the E07 wire/traces/springs can’t really degrade much electrically, so it must actually be the LEDs that are stressed out.

maybe the contact between body tube and tailcap, between tube and the driver is worn out after screwing-unscrewing many times, that why it can be oxidized

Plus the top spring is bypassed with a big mess of solder. That isn’t gold… Batteries and other contacts can get plenty dirty without being oxidized.

Has no one tried to retrofit a new, more clicky, e-switch on this light yet?

I did order my E07 couple of days ago. I did check out as guest. I have asked about the tracking number how long can you expect to wait until you get a reply?

Do you perhaps know if this light has a separate switch or if it is mounted on the driver?

I did receive my flashlight couple of days ago.

Some Impressions of the flashlight.

First impression, it feels smaller then what I did imagine, this is positive, it defintly belong in EDC family, but the pictures online makes it hard to know the real size, so I am glad it turned out to be this size.
It also is very sexy to look at, I bought mind in gun grey color and I don’t regret the choice.
Second impression, with SST20 4000k I find the turbo very impressive, as usually you need to have surfaces to reflect light on to get the wow effect then it will really light up the whole surroundings in a very impressive way considering the size of the flashlight, so yes performance does not disappoint this 7 led configuration really adds that wow factor that I have missed in all my quad led lights.
I really dig the ramp/dim functionality, makes it perfect especially for indoor use, in a seamless way you and adjust brightness according to distance and as you get closer to doors you lower the brightness etc.
Battery life seem to be kind of good, as always it always depend on your use, all these brightness modes and ramp functionality is there for a reason, both in terms of heating protection and battery consumption the whole purpose is to change brightness all the time according to need, the more you do that the better battery life, if you use turbo a lot dont expect any good battery life, but if you use it for short flashes and then go down to high it will be good. I dont have any exact number of the battery life, but ofc you need to compromise you might be in scenario where you want to use turbo majority of the time with this flashlight you simply cant both because of heating and battery consumption, but this is where 7 led configuration and 21700 battery come to play, the “high” mode is even better then last generations quad led flashlight in turbo, and the difference in heat/battery is very big between high/turbo, also the 7 led config makes the “the eye” very wide and big so wow effect is still present in high mode but ofc not as much as turbo.

I still give this flashlight 10 points, it still the most beautiful and powerful flashlight in this size but I will list a few things I don’t like.

1. Aux leds, is nothing for me, it takes away the professional feel when having them on, gladely I can turn it off, the leds on the button I have no problem with it fills a purpose the other aux leds are only for bling bling.
2. Manual and configuration routines are a big nightmare, the manual is very hard to understand, I pretty much need to take help from youtube videos, in one video the person say that the manual included with E07 is not complete, some important information is missing so I will need to check that out… I can understand flashoholics don’t mind this complex configuration options but the truth is no normal person will never use it, they will never change the sensor above 50 degrees etc, or even manage to turn off the aux lights. Yes to summarize while config options are big the whole config system is still a joke to me and laughable. What is missing here is a atleast a secondary button that would help to config, doing all with just one button is a big pain in the ass. I would also like a LED screen like TM26, so I can see more easy what menu in the options I am in etc…

3. The button is not perfect even do it fills it purpose it is not as responsive as you would like it to be, I would want a more tactile one. For the ramp/dim I would like half press option like Nitecore TM26.

I still give 10 points because this is as far as size to performance ratio have come right now, its the most powerful in the size and looks good, configuration is a nightmare but probably worth it. having it set to 50 degrees most likely have a positive effect on the longevity of the leds, since I read people have problem with the leds loose lumen after a while it might be related to having them run too hot…
But 50 degrees I still think is very low, 70 degrees Celsius atleast…but 50 is the default setting now I have to watch youtube videos how to change the sensor myself and calibrate etc… its not fun but I must do it…

I wish they could calibrate the sensor before shipping and also that you would be able to ask them to set the sensor higher so you dont have to do all that yourself.
Putting off aux lights and change the sensor temp is two things you must learn how to do… after this you really dont need to change anything in the config…

2 switches and half presses is obviously adding a 2nd switch input which the firmware can't handle yet, and this driver is out of spare I/O pins (this is a 3 channel driver, not 2), so can't happen with the current driver design.

Their newest light, the E01, has no aux LEDs and no ability to configure the interface. I guess less is more?

It still has a thermal calibration option though, because it’s really hard to get a factory to calibrate it.

TK, did you configure it that way for them with limited UI config? And looks like no candle, lightning modes, etc? I don't see a cfg file for the E01 in the repository?

I've had an E01 on order from Neal for a while now, but it's held up because the trits I ordered with it aren't in stock .

Yes, the UI was created to match a spec from Fireflies. I guess they got enough comments like the one a couple posts ago that they wanted to remove some options.

The E01 config file is there, but it may not have landed in trunk yet. It’s at least in the fsm branch though. And with a pogo pin adapter, it’s really easy to reflash. It’s a FET+3 driver like the PL47 and E07.

Ohh, cool! Boy, I need a pogo pin setup. Is there any good info to make/build/buy a setup here on BLF? Don't know all that much bout them but think the pinout layouts vary. Still unclear how they connect in to stay - hope they don't have to be held in place.

This is what I’m using:

This one is designed to make it pretty easy to handle different pin layouts.

It does have to be held in place, but it’s fairly easy to do… especially on drivers which have a few vias among the flashing pads. The vias align the pogo pins correctly and keep them there. Even without though, it’s not difficult.


Yeah, this deserves one’a them industrial standards everyone would agree on.
Or a new kind of connector. There’s alternatives like short range wireless:

I gotta read up on this, and where to get parts, etc. Think we may have pogo pins at work - probably DigiKey sourced.

For me who work as security gurd E01 looks like a good option but it pales in performance… also… it looks to have a lot bigger candela judging by the beam shot on the website.
For a security guard you want less candela and more lumen. Anyway E07 and ST20 gives a good balance between flood and throw. Throw is overrated I think… for most situations lower candela and high lumen is to prefer…how ever for some people they require good throw all the time… depending on activity… E07 and ST20 give good balance between the two… I dont have exact numbers how much it throw etc…

I might consider the E01 as secondary flashlight… the batterylife should be very good since its only one led and 21700 battery. The price is very good.

Do your images with the above code and it will fit to the screen. Also, since you are using imgur if you add an 'h' to the end of the filename like I did above it will resize it to 1024 width I think.

Odd, I thought it was exactly the opposite… a security guard would probably want to see far away, no?

O'L, when working as an evening security guard, described scenarios where he needed throw to give a shot down long views - he definitely needed some throw in his duties. Interesting he always preferred CW for these lights.
