Fireflies E07 preview

There's been lots of discussions on the switch height and protection on just about every light with a side switch here. Not sure, but thought ThorFire did set it a bit lower, but of course, not low enough. There were issues like this we just couldn't get them to budge on for various reasons, so we eventually settle, like we did with the screws securing down the driver - really wanted a retaining ring. Also wanted a better FET, didn't get that either. It's all about what they can do or can't, pricing, priorities, adding further delays, etc.

I’m not sure why they would resist. It’s a matter of machining and that is about the easiest thing to change. Literally ZERO cost. They have to mill a hole, they can very easily mill a countersink. Just programming.

Perhaps I can help on the next build with machining and manufacturing knowledge.

I can't recall, others might know better. Not sure if we gave it priority, and might have been a slippage issue - when you are running say 6 months behind, and they tell you it would delay another month of this or that, you tend to back off. Of course it doesn't really happen till another 10 months, but of course we didn't know that at the time -- hindsight thing...

If it was a specific resistance to countersinking it then it had to be the switch itself. Either they had stock, wanted to maintain commonality to their other products or simple unavailability. As is, the switch may not be thin enough or the threading wouldn’t close to hold the switch if there was 5mm less of material thickness.

On the other hand, they could accommodate that if they wouldn’t remove off as much from the top, where the fins are.

I’m looking at the Thorfire Q8 and they could of left the ridge/fins on there and countersunk the switch. As it is now, it’s about 3 mm proud of the machined plane. It looks good, but I always chose function over sexy. On the other hand, I’m not selling flashlights.

Anywho….next time.

Black paint removed from h2r nova clip to use on E07. Much better! Ordered a silver Olight S1R/S2R 2 way clip but it’s much shorter, so I did some pocket clip swapping around today. Zebralight clip went to the h2r, new Olight clip went on my old zebra h600w, and the h2r clip was sanded and put on the E07. Still have some polishing and clear coating but it looks good and much better than original clip :+1:

The clear ano eo7 looks very nice!

I received my clear E07 today and one of the main LED’s wasn’t working. I already planned on taking it apart for a Luxeon V2 swap so I wasn’t concerned and got to work.

This is what I found:
D7 was the one not working. Absolutely zero solder on the cathode pad.

And the bottom of D7 is dry as well

But I’m happy to report the L1V2 emitter swap went perfect and it’s all buttoned back up!

Light box readings (raw numbers):
Stock SST20 4000K = 35100
Luxeon V2 5000K = 47200
A 34% gain (but that’s to be expected with it only having been running 6 of the sst20’s)

Guess this one missed QC huh…

And don’t forget the SST-20 4000k and below only come in 95CRI, so it is a bit unfair.

How did it not reflow though? Don’t they use skillets to specifically prevent this?

I’m guessing it was a paste applicator error. I can see maybe the center pad not flowing with how much mass this MCPCB has but the cathode and anode pads flow easily even on this big honking thing. I just can’t imagine it not flowing when the 20 other solder joints, including all 7 thermal pads were good unless it simply didn’t get paste.

Either way literally 1 second of QC should of stopped it from going out the door like that…

No issue with my, love it!

What made you choose the luxeon v2 over all the other swap options available? And what method did you use to reflow?

I like them, best 5000k tint I’ve found yet. I usually reflow with hot air from below but for this one I did it on my glass cooktop.

Love my E07 with sst20 4000k 95cri, a lot more output than my pl47 xpl hi v2 5000k

The writing on the wrapper is quite different on the fake cell too

Took my E07 to work today.


That looks like it would be very difficult to clip onto anything in a bezel-down orientation for deep carry. The lip of the clip, where fabric should slide under, seems to be blocked by the smallest heat fin. Is it as difficult to use as it appears?

It works better than the clip it came with bezel down cause the original clip was so tight I had to struggle with it to slide over anything. The Olight clip, being longer, is easier to lift and slide into my pocket bezel down. But because the head of this light is bigger than the battery tube I MUCH prefer bezel up. It makes it much easier to pull out and return to pocket without fighting getting past the larger bezel. Plus I get to look down anytime and see those cool aux lights and see the light is not on. Others notice it also and inquire about it. Pretty cool:) I remember one time my Olight h2r turned on in my pocket and scorched my leg and burned a hole in my pants :person_facepalming: . That’s the day I started doing mechanical lockout on that guy :smiley: This also solves that issue. Don’t get me wrong, I’m still dreaming of this design, but haven’t found or tried making it, yet……

Wow, sure is a lot of complaining about this light. I’m very happy with all three of mine. I use them for work though, and don’t over analyze every detail.

I can’t believe people buy a light with the highest turbo lumen rating in its class and then complain that it gets hot quick? Buy a Maglite if you want to run all day without the option of awesomeness.

Dull the fins if you feel that they are too sharp. I don’t think mine were that bad, but I rounded the edges with a nail file just to see if it would help. Didn’t take much at all to dull the edges, and I like the sort of worn look it created. They’re like a worn in comfy pair of jeans.

As for the lack of heat path (yet it still heats up too quick???), I don’t run in turbo or high levels long enough for it to matter. The flood on this thing is insane, and I find that running it too high causes a bright hotspot in front of me, and quickly ruins my night vision. Unless you are pointing the light up at something, or down from somewhere very high up, it’s almost impossibly to not blind yourself. A more focused beam is definitely better at these lumen levels IMO.

Only thing I don’t like is the lack of an anti roll with the clip removed.

Are you talking about my vid?
