[♛ FreemeGB] Fireflies E07 7* Nichia/ SST20/ XP-L HI Emitters 21700 Flashlight Group Buy -【 New Copper+Titanium 】

Here’s a comparison of the X-PL HI and SST-20 in a D4S. Both are around similar output/lumens here, the high CRI 4000K SST-20 will have slightly lower output.




Eve and Adam pre 2019

are you referring to the adult toy store?

Can anyone help with this issue?

I received my Fireflies E07 Friday of last week and it has a strange issue that my Fireflies PL47 has never had:

I will take a video to show you what’s happening but when I ramp up to the top of the ramp (not turbo) the light flickers very heavily and rapidly once it reaches the top of the ramp. This happens if I keep holding the button or if I release the button as soon as it reaches the top of the ramp. The flickering happens most of the time and can last anywhere from 2 – 10 seconds.

It also happens if I save the top of the ramp setting as the memory setting and turn the light off then on again.

Like I said, my PL47 doesn’t have this issue and is totally stable once it reaches the top of the ramp

Hi friend, what is the coupon code for buying directly from fireflies?

To me this sounds like there’s a lot of contact resistance, probably caused by grease/dirt on conductive areas. Please try following:

- unscrew the battery tube and the tailcap

- get some IPA (isopropanol) or contact cleaner and q-tips

- clean the non-anodized front face side and end face side of the battery tube

- clean the springs on the driver side and on the tailcap

- clean the outer rim on the inner side of the taicap (that area where the battery tube end side makes contact with the tail cap)

- clean the terminals on your battery (positive and negative side)

  • screw down everything again and try again to see if there’s still flickering

Also, a copper washer in the tail cap may also help.
These are the ones I use:
“Unique Bargains 10PCS 24mm OD 16mm ID 2mm Thick Copper Washer Flat Ring Oil Brake Line Seal” found on Wally World site.
They are a bit thick but the thinner ones I got are slightly warped and I don’t like them as much.
YMMV

code is in the first post.

Any news about cu+ti e07 edition?When will they open for sale?

Hi Freeme, I have the same question:
Any news about cu+ti e07 edition?When will they open for sale?

I’m sort of glad these are not available as I would be forced to buy one and I already own the fantastic E07.




and with red auxiliary LEDs for sure I couldn’t say no.

:slight_smile:

Now isn’t that just the prettiest little thing? :smiley:

Sign me up, y’all know I’m all over that!

:wink:

Nice! I wait for the retail version.

Mine need that copper! Samsung LH351D W6’s on a 30T pull enough to make 7170 lumens! :smiley:

These are 80CRI, yes?

At 85% optical efficiency, you are probably outputting around 8400 lumens.

That’s 84W of power in a single 21700 light…

That is insane.

You need all the heat capacity you can get.

My brightest E07 with the XP-L HI v3 5000k makes about 7,400 lumens at 1s. Actual numbers was posted in this thread but too lazy to look it up.
