Interesting light. I’ve skimmed through the thread but can’t find any details on the driver board, only the aux LED board. What is the diameter of the driver board? Easy to get to and replace?
Also, from the photos of the front with aux board, it looks like the LEDs are on a normal PCB under the aux board. Is this a standard PCB or copper MCPCB? I haven’t seen any info about that either.
Remember too, when they say 10º or 12º they’re talking half angle, it takes 3º or less for a thrower style beam. Just sayin…
I have a couple of question on the UI if anyone can help please?
1. what is the ‘Goodnight’ mode???
2. while in beacon mode, can u increase or decrease the brightness?
3. while in candle mode, is the only option for 30 minutes?
thank you for any help here….
I haven’t attempted to open one, but it looks like the driver is glued in. It’s a FET+3 design, roughly 23mm across, and has spring-side pads for reflashing… but I think the aux LED board must be unsoldered before reflashing will work.
Pretty sure the MCPCB is a copper DTP type, because that’s what Fireflies’ other lights use, but I haven’t taken mine out to confirm.
Also, candle mode doesn’t have a time limit by default.
THANK YOU so much ToyKeeper! This is the first time I have seen or read about the Goodnight, Sunset mode? I was sort of wishing there were settings of less that 30 minutes for the candle.
thanks for all these wild options! The Party Strobe can get really crazy while adjusting 
Lightning Storm is cool, Everett did that one a long time back.
thanks again!

So how long does it last? If there’s no time limit it’d last forever but TK says the max is 4.5h… Is this the default?
This text says nothing about what is goodnight mode and much less how to configure it…
There’s no configuration to the goodnight mode, but I agree, the documentation should at least tell the reader what it does.
Thanks. Glued in, ok, hopefully not to hard to remove. I will be replacing the driver all together. As it’s 23mm I’ll have to get new boards made. Can you see if it’s perfectly round or if there are alterations so it fits in place?
Yeah, it would be weird if it wasn’t copper DTP. It was just that the little that can be seen in earlier photos looks a little funny, but come to think of it, copper DTP boards can have any color with anything on them :person_facepalming:
For that matter, there should probably be some documentation. I haven’t written any yet.
All it has now is a text file I was using as a todo list while writing the code. I sketched out the UI concept there, then checked off the items one by one as I implemented them. Sometimes this gets mistaken for a manual.
Hm… Ordered an E07 with expedited shipping 5 days ago and it still hasn’t shipped from Fireflies.
Guess I shoulda saved the money and just gone with free shipping. I think I’d have gotten the light faster. 
Mine took a long time to arrive but worth the wait.
I opted for XP-L HI version, CW tint.
I have the same tint and LED in a Emissar D4 and D4S which I am really impressed with.
The E07 is brighter than both the Emissar lights. That was expected although not easy to accomplish. It stays brighter far longer and cooler than the D4 but again, that’s expected. I am running a Sofirn 21700 4000 mAh cell while I wait for higher amp capable cells to arrive.
I REALLY like this light. It’s a flooder but with effective throw. I like the UI. The AUX LEDs are cool. It’s extremely bright and well built!
My only complaint: 4 rapid clicks to lockout is silly. I twist the tail-cap anyway so all the AUX and switch LEDs go out.
Ditto. Exact same situation from Nealsgadgets……….
Especially considering that when I ordered my ROT66 last year with free shipping it arrived pretty fast.
I didn't order the black one but your one really looks nice with the purple leds.
Yea, really happy with this combination. They sure look purple to me, and you also. The order said they were blue. I think I would prefer purple. I didn’t have a choice but if I did I think mine would have been the clear body. Waiting to see pictures……
I received my E07 today, ordered with Nichia B emitters. I put a Samsung 40T 21700 battery in it (positive towards head) and the only sign of life I can see is 2 of the LEDs on the switch are on. Same goes for using a Sony VTC5A in the 18650 adapter. No function at all when pressing the switch. Or press and holding the switch. Thinking that maybe the light comes in lockout mode I tried 4 presses with no difference. Unless there is some secret series of presses needed to make the light work, it seems my light is DOA right out of the box. Not completely DOA because the 2 lights on the switch do come on, but I was hoping for more than that. There is a stamp on the side of the box where it says (checker) that says PASS and has the number 12 next to it. The shipping box looked in perfect condition, so did the inside product gift box. Not sure how a light could have been tested, passed inspection, then shipped and now DOA.
Can anyone think of something obvious that I am doing wrong to get this light working?
I am sending a copy of this post to Fireflies (whoever started this thread) via PM.
Any other suggestions would be greatly appreciated. Not sure right now if I feel this light is worth shipping all the way back to China to get fixed, if it is in fact defective.
FWIW, even the lockout mode should light up when the button is pressed… though only at a dim level.
It might be interesting to see what the light does if you click 7 times, or 3 times. But it sounds like something in the driver may be preventing the MCU from receiving power at all, because when the battery connection is made it should flash the main emitters briefly in order to confirm that it booted and is now operational.
