Fireflies E07 preview

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.

Well it depends little bit on scenario, for your information I keep my Sofirn SF36W with me if I need more throw, I have not really compared throw between the sofirn and E07.

Also security guard have different task and also guard differnt objects so it really depends on your task, for me personally low candela and high lumen is better.
Low candela gives almost 180 degree of view, this is good if there is an possible attacker in your near proxity which you might not see with a high candela light…
I think this video describe it well https://www.youtube.com/watch?v=8qSOowE_LsY

Yes as I said… it becomes hot too fast for me… from cold start it become hot very fast… so I dont think they have done a very good job with the thermal performance on this one… its not that its not a problem to operate the flashlight even if its very hot since you hold in the back parts not the head… but with this thermal performance its not strange it have to throttle down a lot… I will try to change the sensor this week to allow 80 degrees… For version 2 I think we could expect better thermal performance… and SST 20 was supposed to have a lot better thermal performance then the nichia then I really wonder how much more bad it was with the nichia. Anyway nothing is perfect this is still better then all other out there, if you dont use turbo all the time you will still get a flashlight the outperform others which using turbo… so its important to keep this in mind… also price is good…

But yeah for version two the focus should be on thermal performance, cause its what reduce the performance right now…

The thermal performance is about as good as it’s going to get. It’s a hot rod and without something double the size it won’t make any difference

I have not said it’s easy… but to move innovation forward they need to think outside the box. Smartphones which share much of similar problems have starting to experiment with vapor chambers, I have not seen any exact numbers of having this and without… but might be worth to try…

75-100 watts. If you want a vapor chamber I suggest gloves :slight_smile:

Yeah, at these kind of power levels(50-70W+), even with so much thermal mass, it’s going to heat up massively.

Phones, at the absolute worst, only have to deal with 7,5-10W.

Yes true, but there is also a lot more space for cooling in a flashlight… vapor chamber seem to be the latest innovation right now in cpu cooling for mobile devices… it might be just a gimmick I don’t know… not seen A/B tests.
