It shows on there website now not to use over 20a batteries on the sst20 emitters. Not much mention about the nichia leds, they must be out.

I still don’t see an explicit warning (all I see is “For SST20 version, around 20A discharge rate needed, LS 20A 21700 recommended”) but it’s good that they now have better recommendations online.. I guess I will try mine with the 30Q to get to know how sst-20 look like before attempting the emitter swap to Samsung.

For something completely different: I have seen people with a mixed blue/purple aux-LED setup. I would have ordered that but I couldn’t find it anywhere so I went with just purple. Are those custom modded or would FireFlies have done that if I had asked?
Edit: Here is a sample image on Neals page (but apparently those are the generic FireFlies product images):

But Fireflies already admitted that (and not due to excessive heat, apparently). See quote at point 6. again: “For E07 SST20 / Nichia version , we only recommend max 20A battery , 20A battery can reach max power for E07 SST20/Nichia version. With a 30T battery on SST20 or Nichia the turbo will go blue no matter how much paste used.” I have not found this recommendation anywhere. Does it come with the instructions maybe?

Edit/P.S.: I don’t want to give the impression that FireFlies is the devil himself. Far from it. They produced a fabulous looking light. They listened to us when we demanded a clear anodized version. (Which is the version I ordered) I just can’t wrap my head around all those tiny details they are lacking. That are sometimes so obviously wrong. Like the PL47 headband. I am really looking forward to their future.


It may be that the Nichia or SST20 just can’t take the current and that’s why they are going blue. If that’s the case, then no amount of improving the heatsink path at the star-pill interface will help. The problem is the peak output of the light is too high for the emitter when used with a full cell.

Are we really believing that any 21700 cells are outputting a constant 49A?! That’s about the point SST-20s die at (x7 emitters).

I’ll buy the Ti version if there is it’s all Ti and no copper etc to ruin the look.

Easy enough to measure if anyone cares to do that (I have no E07)

Ordered two, but decided to order one from BG, the other from FF, so it won’t really matter who sends faster.

Used your links and codes, thanks!

Got my 3rd E07 from Neal and he shipped much faster than Fireflies direct.

the MCPCB have little thermal paste but not enough spread evenly. Had to add more for extra heat transferring Smile

Where can the XPL HI V3 3A NW 5000K version be had? It’s listed in some of the descriptions but there’s no option to select it.

Got my grey e07 from neal. It flickers on moonlight. No matter which battery i use. Anyone else experience this?

never fear shadows…it means a light shines nearby

Apparently it’s a known issue (I believe I read about it in the FW3A thread that all 3 FF lights do that).
My clear E07 didn’t do it with the stock SST’s but all you should have to do is set the ramp floor a little higher (try one step at a time).

Is there an ETA for shipment for the next version that addresses the thermal paste and TIR positioning issues? Thanks.

With Anduril, the bottom of the ramp is moon. It doesn’t have a separate moon level like NarsilM does.

About the flickering, it seems to vary per 7135 chip. Some do it, some don’t. I think I may have found a workaround though, and it’s included in recent builds.

Correct. The lowest setting. As far as i see, its the only light that does it out of all my ff lights.

Which one is the CORRECT output for SST-20 5000K?

Neal’s website has:7x SST20 5000K NW 3500lm

Fireflies website have: 7x SST20 5000K NW 4800 lumens Turbo brightness

Solitude breeds contemplation which creates clarity. 

Environment molds a person. Perseverance changes them.

Yeah, that’s what makes the issue tricky. I don’t have any lights with the flickering issue, so I’ve had to take guesses about how to deal with it, send files to other people, and hope they’ll be willing to test it for me. I think I finally found something which works though.

@wolfdog, it’s the 2nd one.

The 3500 lumens is for the 4000k version and below.
