[Unboxing] FIREFLIES E01 21700 Flashlight

Thank you for your unboxing. The pictures are great, particularly the size comparison with the E07. I already own two E07s, which I love.

So, I was wondering where you see the E01 fitting into the FF lineup, other than its lower price point.

In other words, why would anyone with an E07 be interested in owning the E01? (It appears taller than an E07. I was kind of hoping it would be more pocket friendly than the E07, but from a size standpoint, it doesn’t appear to be.)

I would be interested in your perspective, since you own both lights.

Maybe I’m dumb, but why does the star say Cree XM-L when it’s supposed to be a Luminus SST-40?

Thank you for the beamshots, can you do a comparison beamshot with something similar. like the Emisar D1 (I know is reflector instead of optic) for reference?

Thanks!

Because both the XM-L2 and SST-40 use the 5050 footprint and crees are way more popular so thats what the mcpcb makers put on their boards.

I particularly like this:

… because it makes the E01 a great dev host. I made good use of it while adjusting thermal regulation code recently. This graph shows a before/after of how that went:

But that doesn’t matter to most people. It also works well as, um, a flashlight. :slight_smile:

Will you put FF E01 on the FSM list?

or a full Anduril?

Thanks for this, mine is coming

Yes, I just got delayed while working out the details of the source code release. I need to merge the E01 branch and publish it.

It’s easy to reflash if you have the right pogo pin adapter, but difficult otherwise.

I merged everything and put a build online:

Fwiw I found my E01 pretty simple to flash with an soic clip.

Desolder led wires
Push led- wire down into hole
Use small poker tool to push out driver
Flip driver over in place and attach clip to flash.
You DON’T have to mess with the switch wires at all and no components on board interfere with the clip!

I built anduril for the PL47 target, the ROT66 target will work too but the ramp shape will be off. I need to update one of my E07’s back to an UTD pl47 build asap, (it’s ramp is visibly nonlinear after I loaded a ROT66 based hex onto it).

I just found this thread today. Fantastic pictures and great info. Thank you. :beer:

I have been thinking about getting one of these… I am now convinced I need to do it. :money_mouth_face:

I got the confirmation that the cross pattern is definitely an original Luminous devices, directly bought from the manufacturer

I see they removed the aux programming pad as it’s not needed to disconnect the aux board for flashing
the PL47 has it too but you cant get to it

It's funny because it looks just like an XM-L2, on a Cree XM-L board to boot.

Also Atmel MCUs changed the markings recently, first being thought it’s a Chinese fake, reason Microchip bought Atmel
Likely also production of new MCUs in China now so spotted first on Chinese drivers

Its a year now and still MCUs from Mouser show old markings probably will change too until they run out of stock

Who’s adapter and what pogo pins do we order? Links please?

I don’t get it.

They may be afraid of burning out the SST40, which can burn its bond wires around 9A. It hits max output around 6A iirc

I think this will be my next lantern. :person_facepalming:
